Aalborg Portland

How are we engaging in symbiosis?

The cement producer Aalborg Portland is the oldest link in the industrial symbiosis network in Aalborg. Over the years, Aalborg Portland has participated in several important symbioses as illustrated on the map.

Symbiosis between Aalborg Portland and Port of Aalborg.

In this symbiosis, Aalborg Portland receives purified sand from the Port of Aalborg. The sand is derived from the regular dredging of the Limfjord, which is necessary to maintain access for shipping in the fjord. Since sand, combined with lime, is the principle raw material in grey cement production, the sand is used in Aalborg Portland’s cement production. Prior to this collaboration, the purified sand was dumped into the sea. The quantities of purified sand vary over the year depending on weather conditions. In 2019 just over 150,000 tonnes of sand were recycled.

Symbiosis between Aalborg Portland and Nordjyllands Power Station.

This is a two-way symbiosis, whereby Aalborg Portland delivers lime sludge to Nordjyllands Power Station and receive gypsum in return. Lime sludge is a by-product of cement production, generated at Aalborg Portland when lime is mined from the limestone quarry. The lime sludge is used at Nordjyllands Power Station for flue gas treatment. The flue gas treatment process generates gypsum of a sufficient quality to be used in cement production at Aalborg Portland.

Energy symbiosis

Aalborg Portland is a key player in the energy symbiosis. Aalborg Portland currently supplies surplus heat to Aalborg Utilities, providing district heating for approx. 30,000 households in Aalborg Municipality. However, this figure is expected to increase to 50,0000 households in the future, a target that Aalborg Portland is working towards through a new supplementary agreement with Aalborg Utilities.

Symbiosis between Aalborg Portland and the Wastewater Treatment Plants

Aalborg Portland is also involved in a symbiosis with the wastewater treatment plants East and West.  The wastewater plants have a number of residual products in the form of sludge and materials from screening (toilet paper, etc.). As part of the symbiosis, these residuals are processed at a sludge drying plant and then sent to Aalborg Portland to be used as fuel in cement production. Approximately 3,000 tonnes were recycled in 2019.

How do we generally work with sustainability?

Although Aalborg Portland is part of a global group, all the company’s development activities are centred in Aalborg, where the company’s research and quality department is located. Development and production of cement products at Aalborg Portland is focused on socio-economic sustainability. Based on a holistic approach, the company contributes to the global achievement of the UN’s sustainable development goals, both economically, socially and environmentally.

Development towards sustainable production started in the 1970s, when energy efficiency came into focus. Since then, tremendous strides have been made through numerous initiatives involving alternative fuels, surplus heat for district heating, recycling of waste etc.

Today, sustainable production remains a key focal point for employment, technological development and exports. Aalborg Portland contributes to the UN-2030 agenda for sustainable development, and several of the associated 17 SDGs, as well as the COP21 Paris global climate agreement.

Aalborg Profil- og Smedeværksted

How are we engaging in symbiosis?

As part of the Sustainable Synergies project, APSV has been exploring opportunities for recycling Aluzinc offcuts from NB Ventilation for use in the company’s production of cladding. The symbiosis between APSV and NB Ventilation is a classic exchange of materials, by which the scrap and waste from one production can be reused by another company. The material is galvanised steel plate, which is corrosion resistant and durable. NB Ventilation annually discards a significant quantity of Aluzinc scrap. Supply of the residual quantities negates the purchase of new Aluzinc sheets, as well as the transport from China. Moreover, APSV also saves resources because their residual product no longer has to be remelted. Transport of material for remelting is avoided, in which the corrosion-resistant alloy is also lost.

”… man sparer på ressourcerne, fordi det giver mening.”

Peter Le Dous, ejer

Aalborg Recycling

How are we engaging in symbiosis?

Aalborg Recycling is a key enterprise in two symbioses around plastic recycling. One is an ambitious collection and processing of agricultural foil. This is quite a challenging process, as the plastic resource is mixed with soil and spread out geographically. Aalborg Recycling is establishing a production plant for this process. The potential environmental benefit of this form of recycling is enormous, as huge quantities of agricultural foil are currently not being recycled.

In the other symbiosis, plastic sheets are collected at Aalborg Recycling with a view to becoming new plastic of similarly high quality. The quantities of plastic sheets are so small that strong collaboration between companies is needed for it to be feasible. Now they shall be collected with a view to recycling them.

Agricultural plastics are not handled well enough today. We will create a business based on the recycling of the plastic in North Jutland in collaboration with a range of companies.

Bernt Pedersen, Aalborg Recycling Afdelingschef

How do we generally work with sustainability?

Aalborg Recycling is one of the country’s leading companies in the recycling of iron and metal scrap, demolition, cutting work and cutting tasks with recycling as its primary business area. Scrap is a key business area that requires strong relationships with many companies, established logistics and optimal possibilities for collecting other fractions, e.g. utilising unladen journeys. This benefits both the environment and the companies of North Jutland.

Aalborg Utilities

How are we engaging in symbiosis?

Energy symbiosis

Aalborg Utilities is a key enterprise in energy symbiosis, whereby surplus heat from several local companies accounts for an increasing proportion of the district heating. The use of surplus heat that would otherwise be wasted reduces primary energy consumption in heat production and affords economic and environmental benefits. Aalborg Utilities is continuously assessing, which companies with surplus heat can participate and remains in ongoing dialogue with potential contributors. Utilization of surplus heat is one of several methods that Aalborg Utilities employs to reduce the use of fossil fuels, enabling district heating supply to be derived from completely green energy by 2028.

District cooling

However, Aalborg Utilities’ role in Industrial Symbiosis Aalborg extends beyond collaboration with local companies that contribute to greener district heating. Aalborg Utilities also collaborates with Aalborg Portland and the new University Hospital in Aalborg to provide a sustainable alternative to traditional cooling systems. District cooling shall avail of the constantly cold water of Aalborg Portland’s limestone quarry to cool the hospital buildings. Cooling of the hospital is an important step in developing comprehensive district cooling systems in Aalborg. More and more companies in Aalborg are expected to receive district cooling in the future.

Nordjyllands Power Station and Aalborg Portland: Symbioses based on fly ash, lime sludge and gypsum

” Nordjyllands Power Station”, one of the companies in Aalborg Utilities, is involved in numerous symbioses that extend beyond district heating and cooling.

Such symbioses include fly ash (a residual of incineration at the power plant) used by various companies in the area. Instead of dispatching this by-product to landfill, it is used in Aalborg Portland’s cement production. The asphalt manufacturer Colas Denmark also receives fly ash from the power plant in Aalborg. E-mineral is the company responsible for the nationwide trade of the by-product from power plants. In another two-way symbiosis, Nordjyllands Power Plant receives lime sludge from Aalborg Portland and delivers gypsum back to them. Lime sludge is a by-product of cement production generated by Aalborg Portland’s mining of lime from their limestone quarry. The lime sludge is used at Nordjyllands Power Station for flue gas treatment. The flue gas treatment process generates gypsum of a sufficient quality to be used in cement production at Aalborg Portland.

Water symbiosis with the agricultural sector

Finally, Nordjyllands Power Station is also involved in a symbiosis with the agricultural sector in the area. Previously, surplus water from the fields was pumped into the Limfjord. Now around 120,000 m3 of water is collected and transported through a complex pipe system to Nordjyllands Power Station, where it is used in the gypsum production process. Consequently, the surplus water replaces groundwater in the process.

That is not all

Aalborg Utilities is also engaged in a number of other symbioses within other supply industries. Return to the map to read more.

Holistic thinking and sector connections, which is precisely the essence of Environment++, are absolutely crucial for us to reach the goal of a sustainable restructuring of the energy systems in Aalborg and Denmark in general.

Aalborg Wastewater Treatment Plant East

How are we engaging in symbiosis?

Wastewater Treatment Plant East together with Wastewater Treatment Plant West engages in symbiosis with Aalborg Portland, Reno Nord and Kingo Recycling respectively. The wastewater treatment plants in Aalborg East and West have numerous residual products in the form of dried sludge, screened waste (cloths, bandages, condoms, etc.) and sand. The combined surplus sludge from both plants is fed into the plants’ digesters to be used in biogas production. The digested sludge is subsequently dewatered and delivered to the sludge drying plant to be dried and become biogranulate. The biogranulate is sent to Aalborg Portland, where it is utilized as biofuel, substituting coal and petroleum coke. It also substitutes raw materials in cement production via the ash fraction. Aalborg Utilities supplies around 3.3 to 4 tonnes of biogranulate to Aalborg Portland annually. Screened waste is delivered to Reno Nord, where it is incinerated to produce district heating. The sand is collected by Kingo Recycling, sanitised, and subsequently used in noise barriers.

How do we generally work with sustainability?

Both wastewater treatment plants in Aalborg are classified as MBNDK treatment plants, making the plants among the most advanced in Denmark. The wastewater undergoes a mechanical, biological and chemical treatment, and Wastewater Treatment Plant East has the capacity to treat wastewater from 96,000 population equivalent. After treatment, the wastewater from the plant is discharged into the Limfjord.

Aalborg Wastewater Treatment Plant West

How are we engaging in symbiosis?

Wastewater Treatment Plant West and Wastewater Treatment Plant East are engaged in a joint symbiosis with both Aalborg Portland, Reno Nord and Kingo Recycling. Residual products from the wastewater treatment plants in Aalborg comprise dried sludge, screened materials (cloths, bandages, condoms, etc.) and sand. Biogas is produced from the total surplus sludge production from both plants, which is fed to the plants’ digesters when it is separated from the wastewater. The digested sludge is subsequently dewatered and driven to the sludge drying plant, where it is dried and turned into biogranules. At Aalborg Portland, the biogranulate substitutes coal and petroleum coke as fuel. It also substitutes raw materials in cement production when it becomes part of the ash fraction after firing. Aalborg Utilities supplies around 3.3 to 4 tonnes of biogranulate to Aalborg Portland annually. Screened waste is incinerated at Reno Nord to become part of the district heating production.  Kingo Recycling collects the sand and sanitises it for use in noise barriers.

 

How do we generally work with sustainability?

Both Wastewater Treatment Plant West and Wastewater Treatment Plant East are classified as MBNDK treatment plants.

Alfa Laval

How are we engaging in symbiosis?

Alfa Laval, in collaboration with Aalborg Utilities, engages in energy symbiosis in Aalborg. In the symbiosis, surplus heat from Alfa Laval’s production is supplied to the Aalborg Utilities district heating network. In general, the industrial sector plays a major role in the development of a sustainable heat supply in Aalborg, whereby conventional heat sources are being replaced by greener initiatives. The company increased its share of surplus heat supplied to the network in 2020.

How do we generally work with sustainability?

Alfa Laval is one of the world’s leading suppliers within heat transfer, centrifugal separation and fluid handling. 

Alfa Laval’s relatively new office building on Gasværksvej in Aalborg has received a DGNB silver certificate. DGNB certification is a guarantee that a building is sustainable and that sustainability is considered in all aspects of the building. This also means that all the building materials selected and processes must be traceable back to the manufacturer and be of sustainable materials. The office building has i.a. a low energy rating, as solar cells and solar shading are deployed to reduce energy consumption.

Alfa Laval in Aalborg develops, delivers and services boilers, burners, heat exchangers and inert gas burners for ships and industries worldwide. In recent years, their Aalborg department has also had an increasing focus on the development of green technologies for shipping, such as scrubber solutions for cleaning sulphur gases from funnels on ships. In addition to the sustainable initiatives in Aalborg, the company has many more sustainable initiatives and enterprises on a global level.

Bobach Stålentreprise

How are we engaging in symbiosis?

Bobach Stålentreprise has been strongly involved in symbiosis development in Aalborg. For example, the company is part of a symbiosis, in which a handful of production companies share residual materials with the socio-economic Råt&Godt, transforming residual products into modern, long-lasting design furniture. Environmental and economic gains go hand in hand in this symbiosis: Bobach Stålentreprise saves money, as they do not have to pay for the disposal of the waste themselves, Råt&Godt gains a financial benefit from the sale of the furniture, and the collaboration provides numerous environmental and social benefits in the community. At the same time, the symbiosis has been a positive media story and provided a platform for new collaborations between the companies.

Bobach Stålentreprise is also in symbiosis with a number of steel fabrication companies in Aalborg East, which receive corrugated plastic sheets in the form of spacers between the steel plates. Although the 2-10 mm thick plastic sheets are made of a pure plastic material and are therefore very suitable for recycling, the individual company’s quantities have been too small to bear the logistical costs of recycling. Therefore, the plastic sheets have typically thus far been sent for incineration along with other waste fractions. In the symbiosis, they must now be collected at Aalborg Recycling with a view to becoming new plastic of similarly high quality.

It is a collaboration we are proud of!

Helle Bobach, Director

How do we generally work with sustainability?

Bobach Stålenterprise A/S is a certified fabrication and engineering company, which executes everything from small tasks to large advanced steel structures. The company designs and projects tasks within balconies, railings, stairs and others. It is a multigenerational family-owned business that takes a practical approach to sustainability. Obviously, it makes sense to save on resources!

Brunø Stål

How are we engaging in symbiosis?

Brunø Stål is active in a number of symbioses with companies in the local area. The company collects a sizable quantity of corrugated plastic sheets used as spacers between the steel sheets delivered from their supplier. This generates an amount of waste that can be readily recycled, as the material is clean. Together with other smaller steel processing companies in the Aalborg area, Brunø Stål will collect the plastic sheets and jointly ensure that they are transported for recycling, rather than incineration.

In addition, an energy consultant investigated how the buildings could be heated and energy improved. Although the investigation did not yield a basis for a symbiosis on that issue, Brunø gained specific knowledge of the decision-making process, which also yielded an environmental effect.

It is good to have a common collection system, so we can take care of the environment.

Torben Kjær, Director and owner

How do we generally work with sustainability?

Brunø Stål ApS is a steel fabrication company in Aalborg, which specialises in the fabrication of steel and leaf springs as well as project engineering tasks in steel. The company manufactures and assembles i.a. columns, beams and stairs in steel as well as railings and guards.

Colas Danmark

How are we engaging in symbiosis?

The asphalt producer Colas Danmark A/S has joined forces in a symbiosis with Nordjyllands Power Station for the exchange of the residual by-product fly ash. Fly ash comprises fine particles, a by-product of incineration at the power station. Instead of sending this by-product to the landfill, it is used i.a. at Colas Denmark in the production of asphalt. Apart from Colas Danmark, the local cement producer Aalborg Portland also receives some of the fly ash. 

As a global market leader, the Colas Group is conscious of its responsibility for the climate. Consequently, the group has over the years introduced a large number of global development initiatives.

Companies in Aalborg East

How are we engaging in symbiosis?

There are a number of companies in Aalborg East that contribute to various symbioses.

Leasing rather than purchase of transport equipment

One symbiosis involving companies in Aalborg East is product-to-service offers, in which KS Group participates. Customers can either choose to buy or lease such equipment as handcarts from the company. This symbiosis demonstrates how new business collaborations with other companies involving leasing can lead to optimisation of resource and material consumption.

Green appliances

Various companies in Aalborg East, especially housing associations, are also collaborating with De Grønne Hvidevarer (DGH), which has been collecting and renovating domestic appliances for resale to private individuals for several years. In this symbiosis, new models are tested for sale to companies based in Aalborg East. The aim is to make it easy to replace domestic appliances with renovated ones delivered with a warranty and possible service agreement. The extended lifetime of the appliances yields a significant environmental effect by reducing the need to produce new appliances.

Local treatment of oil-water mixtures

This broad group of symbiotic companies also includes Kingo Recycling’s customers. For a number of years, they have been sending oil contaminated process and wastewater to South Jutland for treatment. Consequently, several hundred heavily laden trucks had to drive through Jutland each year. Kingo Recycling has now built a business based on local water treatment that minimises the need to transport it out of North Jutland. This symbiosis is a good example of how a resource can be turned into a business opportunity by retaining it in the immediate area while enabling new symbioses between companies.

Surplus heating

Grocery stores in the area deliver their surplus heating to the district heating network, thereby contributing to greener district heating.

Fibertex Personal Care

How are we engaging in symbiosis?

The company has been involved in the development of a number of symbioses in recent years. The company uses e.g. in its machines a so-called sieve belt, a conveyor belt of 4.5 x 75 meters made of very strong polyester. It is changed ten times a year and it would be a great advantage to be able to reuse it afterwards. Consequently, Fibertex together with other companies teamed up with the socio-economic workshop Råt&Godt and an industrial designer to develop a new design line that utilises the surplus materials of the companies. Initially, a series of tables and lamps are being developed by the designer Mikkel Huse. The combination of strong design and local production in Aalborg East are key elements in the collaboration.

Moreover, the concentrated nature of the business park in the Aalborg East area also affords opportunities for a common recycling scheme for wooden pallets, of which Fibertex is a part. At many companies today, it is customary to discard used pallets, and companies often pay for collection and disposal. Consequently, there is a potential for increased recycling of wooden pallets, which makes good sense both economically and environmentally. Therefore, Fibertex Personal Care is also linked to a recycling scheme for the recirculation of pallets among companies, with the Hobro-based company LC Emballage as the key logistics hub and distributor.

We would never have thought of making designer lamps from our sieve belts.

Mette Due, Quality and Environmental Manager, Fibertex Personal Care

How do we generally work with sustainability?

Fibertex Personal Care produces non-woven materials for the hygiene industry. The company’s product portfolio illustrates their importance as a player in the hygiene industry’s value chain.

Fortum

How are we engaging in symbiosis?

Aalborg East Business Park is home to numerous companies that generate oily process and wastewater in their operations. These companies have thus far transported this water to South Jutland for treatment, oil separation and cleaning of its components. The unnecessary transport of tonnes of water on heavily laden tanker trucks formed the basis for a collaboration between Kingo Recycling and the companies in Aalborg East. The contaminated water is collected and treated locally in Aalborg and separated from the oil. Fortum still receives the environmentally hazardous components of the mixture, which they are experts at processing properly. The symbiosis not only represents an environmental benefit due to the CO2 savings by minimising transport, but also exemplifies a business opportunity arising on the basis of a resource that negatively impacts the environment and which can be treated more efficiently for both customers, companies and the environment.

Treatment and separation are continuously improved, with the aim of increasing the quality sufficiently, so that the recycled oil can substitute new oil products.

Over the years, numerous companies in the industrial area of Aalborg East have been sending process water and wastewater containing oil for treatment to South Jutland. Consequently, several hundred heavily laden trucks have to drive through Jutland every year. Kingo Recycling has built a business based on local water management, so that as little as possible has to be transported away from North Jutland. Kingo Recycling delivers the oil-water mixture to Avista, which separates waste products and water from the oil, so that it can then be recycled. The waste materials are managed at Fortum. In collaboration with Sustainable Synergies, a number of symbiosis opportunities with local companies have been considered as a part of business development.

The symbiosis is a good example of how a resource can be turned into a business opportunity by retaining it in the immediate area, while generating opportunities for new symbioses between companies. Consequently, it has also been investigated, whether the separation can be of such a high quality that the oil can replace the consumption of new oil products at other companies.

Through the massive saving in transport, the symbiosis yields clear environmental benefits that include a significant reduction in CO2 emissions.

How do we generally work with sustainability?

Kingo Karlsen A/S is a demolition company that works determinedly to develop sustainable solutions and disseminate knowledge and expertise within the sustainable demolition and recycling of building materials. The company is committed to six of the UN’s 17 Sustainable Development Goals in particular, and their vision is to become the Nordic region’s synonym for environmentally sound demolition conducted with respect for people and the world we live in.

Kingo strives to ensure that environmentally hazardous substances do not spread to the environment, groundwater and the world’s oceans by sorting hazardous substances from the building mass during processing. Once hazardous substances have been removed and delivered to an approved waste recipient, the remaining clean building mass can be reused and recycled for the benefit of the environment. Kingo is also keenly focused on sustainable industrialization by e.g. treating and reprocessing construction waste products for recovery. The quality of the end product is so pure that the soil can be used for special purposes demanding extraordinary requirements for quality.

The company recycles up to 98% of the building materials processed, and the goal is for recycled and reused building materials to become the preferred material choice in new construction projects.

Kirk Skumteknik

How are we engaging in symbiosis?

A small company with a potentially huge environmental effect. Kirk Skumteknik develops, produces and installs insulation solutions for district heating wells. Residuals from their production could be incorporated as insulation material into the products of RC Beton, which produces concrete elements with built-in insulation. Moreover, the company received assistance to expand its business area, as spreading the solution will beneficially impact the environment. Today, the high-tech district heating pipes are connected in uninsulated holes (wells) in paths and roadsides, from which heat is lost.

It is a completely new product - a solution you cannot do without.

Jesper Sand Kirk, business owner

How do we generally work with sustainability?

Kirk Skumteknik offers a complete insulation solution for district heating wells. The insulation enables a significant reduction in heat loss from the district heating network, which in itself is economically viable, but also minimises and eliminates operational and maintenance challenges.

KS Gruppen

How are we engaging in symbiosis?

The transition from selling products to selling services is often mentioned as a good way to reduce environmental impacts, because it can lead to less ‘equipment’ laying around at the customers. In this symbiosis, the KS Group demonstrates how this can be specifically done based on their sales of transport equipment. In their new business model, customers can either choose to buy or lease e.g. handcarts from the company. The service model yields clear positive environmental and energy effects and affords KS Group a new business area, where they hold a strong position in high-quality transport products. At the same time, the symbiosis illustrates how new business collaborations with other companies within leasing can lead to optimal resource and material consumption.

This benefits both business and the environment.

Claus Svensk Jessen, CEO

How do we generally work with sustainability?

KS Group operates within four key areas: wheels, transport equipment, ergonomics and fixtures, providing a 360-degree solution that addresses all the customers’ needs from project development to workstations.

LC Emballage

How are we engaging in symbiosis?

Private individuals often use moving boxes over and over again, but other cardboard boxes are generally not recycled. Consequently, there is tremendous potential for making cardboard box consumption more circular, with LC Emballage as a focal point in the symbiosis to realise this potential in Aalborg. The company in Hobro is collaborating with companies in Aalborg East to achieve a cheaper and more environmentally friendly packaging solution. LC Emballage offers to buy used cardboard boxes from one company and sell them to another, providing benefits for all parties. LC Emballage buys used cardboard boxes at a significantly better price from the individual company than if the boxes had ended up as recycled or combustible waste.

LC Emballage also engages in a symbiosis for the recycling of wooden pallets. The company purchases a wide variety of pallets and pallet frames, including disposable pallets and damaged pallets, which are repaired, sorted and resold from their warehouse in Hobro. Through such a scheme, companies in 9220 area can have their pallets collected and receive a modest sum for those pallets that can be recycled. It is a simple, stable, and environmentally friendly solution to tackle the issue of unreturnable pallets.

When companies in an area work together to recycle pallets and cardboard, logistics become better and recycling more attractive.

Erik Lund, business owner

How do we generally work with sustainability?

LC Emballage’s business model is recycling. The environmental effect is central to the company’s daily operations and creates the possibility for a consistent supply of pallets for multiple purposes. Extensive experience ensures that there are buyers for each pallet stored in their large warehouse in Hobro. Cardboard boxes is a newer business area and the business is growing right now. It started with recycling and repairing pallets, later it turned out there are also tremendous environmental benefits and business opportunities in cardboard boxes. Subsuppliers are especially interested in recycling boxes that are in perfect condition. The boxes are used everywhere where it is not important to have your own logo on the packaging, or where customer company wants to signal their consideration for sustainability.

Mani Pine

How are we engaging in symbiosis?

The company was the initiator of a symbiosis in Aalborg. One partner is Salling Entreprenørfirma, which collects large quantities of wood materials from the demolition of old buildings. Another partner has large quantities of functional steel bolts that have only been used once in packaging. Instead of discarding these residual materials, both steel bolts and wood were used in the manufacturing of furniture. The symbiosis was based upon demand for sustainable products. 

How do we generally work with sustainability?

The company’s core business is custom furniture. When customers order a high-quality product that is really desired, it is less likely to be replaced. Tailored durable solutions are sustainable as opposed to use-and-throw-away ones, because they ensure that production directly matches the individual specifications of each order. Thereby minimising waste. Timeless and stylish quality solutions afford a longer product lifespan, which is important for sustainability. 

To refresh sold furniture items, the company offers customers the possibility to order sanding and new oiling of items, or even new legs, for a modest price. A new look almost for free – that extends its lifetime. Both Azobé wood from wharfs and ship planks of other types of wood with patina are used in the production and design of new furniture. This is advantageous both from a design and environmental perspective.

There are also specific projects in the pipeline to develop a range of outdoor furniture made from a residual material – a granulate of clothing fibres. A new tabletop concept is also under development, using offcuts from production that are cut into rods and assembled to form a strong, durable tabletop, which is then veneered with oak. This reduces waste and generates a new quality product.

Maskinfabrikken Fuglsangs eftf.

How are we engaging in symbiosis?

Maskinfabrikken Fuglsangs Eftf. produces steel components, i.a. for wind and offshore projects. As part of the Sustainable Synergies project, the company has been investigating the possibilities of recycling plastic sheets from the packaging of raw materials by participating in a symbiosis with Aalborg Recycling.

How do we generally work with sustainability?

Maskinfabrikken Fuglsangs Eftf. moved to Port of Aalborg in 2019 in connection with a major expansion and modernisation of its production facilities. This afforded improved conditions, especially for operations within their offshore and wind energy department. The company currently has around 100 employees, divided between CNC machining, water, plasma and laser cutting of components, the manufacturing of structures for the offshore and wind energy sector, as well as assembly and service.

The move to a centralised business park location offers advantages. It is the first step in becoming a greener company. Compared to the previous facilities, the new factory affords savings in both heat and energy resources. There is less transport internally, improved waste sorting and more recycling. The infrastructure also provides greener transport of large-scale structures, both by sea and freight transport by rail. This yields positive environmental impacts. Collaboration and development opportunities are also enhanced, because customers are closer, laying the foundation for potential new symbioses in the future.

NB Ventilation

How are we engaging in symbiosis?

Sheet metal offcuts

NB Ventilation is involved in a number of symbiotic collaborations due to the large amount of Aluzinc offcuts that occur in their production of ventilation systems. A neighbouring company, Aalborg Profil- og Smedeværksted, is interested in using some of the material. In addition, NB Ventilation and companies from other industries are part of a joint symbiosis, in which they supply surplus materials to the socio-economic workshop Råt&Godt. Here, a new design line based on surplus materials is being developed by an industrial designer, especially for production at Råt&Godt. Initially, a series of tables and lamps are being developed by the designer Mikkel Huse. The combination of strong design, good residual materials and versatile local production in Aalborg East are the key elements in the collaboration.

Plastic sheet

NB Ventilation also engages in symbiosis with a number of steel processing companies in Aalborg East, which receive corrugated plastic sheets that act as spacers between the steel plates from their supplier. Although, the 2-10 mm thick plastic sheets are made of a pure plastic material and therefore easily recyclable, the individual company’s quantities have so far been too small to justify the logistical cost of recycling. Consequently, the plastic sheets have typically been sent for incineration along with other waste fractions. In the symbiosis, the sheets are collected with a view to becoming new plastic of a correspondingly high quality.

Hand tools

Hand tools that no longer work are typically discarded as repair is expensive. This is not the case at NB Ventilation. The company has joined forces with the socio-economic company Råt&Godt to prove that it is possible to extend the life of a large proportion of the hand tools that are discarded. At best, the company takes back the repaired hand tool for the benefit of both the economy and the environment.

Our core business is green - now the company must be too!

Per Højbjerre, CEO

How do we generally work with sustainability?

NB Ventilation A/S produces ventilation units for both housing, office and industry, primarily focused on comfort ventilation, industrial ventilation and energy-efficient heat recovery. Production ranges from small residential units, units with built-in fire compartment, ordinary comfort systems, to huge customised industrial systems with airflow of more than 120,000 m3/h. All in all, the product, ventilation with heat recovery, is centred around optimal utilisation of resources. The company is developing from a craft-based production to a modern industrial manufacturer through development projects with a particular emphasis on sustainable transition.

Nye Aalborg Universitetshospital

How are we engaging in symbiosis?

The building of the new university hospital, thanks to a collaboration with Aalborg Utilities and Aalborg Portland, paved the way for a completely new symbiosis group in Aalborg. The companies, Aalborg Utilities and Aalborg Portland, joined forces on a sustainable alternative to the traditional cooling systems: They plan to use the constant cold water from Aalborg Portland’s limestone quarry to cool the hospital buildings. Cooling of the hospital is a vital step in developing district cooling systems in Aalborg, affording an opportunity to connect more companies to the system in the future.

Port of Aalborg

How are we engaging in symbiosis?

Port of Aalborg is part of a symbiosis, in which purified sand is utilised by the cement producer Aalborg Portland. The sand is derived from the periodic dredging of the Limfjord, which is necessary for ships to navigate the fjord. Since sand, combined with lime, is the primary raw material for the production of grey cement, the sand is used in Aalborg Portland’s cement production. Prior to this collaboration, the dredged sand was deposited in the sea. Quantities fluctuate throughout the year depending on weather conditions, but on average approx. 100,000 tonnes of sand are recycled annually.

Symbioses are an integral part of our sustainable business park and are incorporated into the development and design of both our own and our customers' companies.

Jesper Raakjær, Port of Aalborg Development and HR Manager

How do we generally work with sustainability?

Port of Aalborg is a modern inland port with a 360-degree view, multimodal logistics solutions, and an unambiguous focus on supporting the realisation of Aalborg Municipality’s business and sustainability strategy. As Denmark’s largest inland port, Port of Aalborg’s development strategy also has a clear focus on the developing the surrounding business park, which has been designated as Aalborg’s future growth zone.

Sustainability is a focal point for the port’s activities, from which the role of industrial symbiosis facilitator emanates. Port of Aalborg supports green transition both locally and globally. In collaboration with a number of local actors that include Aalborg University, the municipal authorities, utilities, companies and business networks, determined efforts are being made to develop Green Hub Denmark and showcase Aalborg on the world stage as a leading sustainable industrial symbiosis.

In addition, we are actively working on the UN’s 17 Sustainable Development Goals. Internally, Port of Aalborg also reduced electricity consumption and CO2 emissions by approx. 40% from 2010 to 2018. Moreover, environmentally friendly cranes, electric bicycles and electric cars, light-controlled LED lighting outdoors and indoors, energy optimization of buildings, recycling of residual products, establishment of photovoltaic systems and cycle paths, etc. have been implemented.

Råt&Godt

How are we engaging in symbiosis?

Råt&Godt is a socio-economic workshop with a business model that is deeply rooted in sustainability. Therefore, it only makes sense that Råt&Godt is also a key company in Aalborg’s symbiosis network.

In this symbiosis, hand tools are exchanged between companies. Hand tools are typically discarded if they do not work, because repairing them is expensive. Consequently, the socio-economic company Råt&Godt has joined forces with NB Ventilation to investigate, whether it is possible to extend the service life of the hand tools discarded by production companies by repairing them. There is no time here to see if the tool could be repaired. At best, companies can take the repaired hand tool back for the benefit of both the economy and the environment.

The combination of strong design and versatile local production in Aalborg East are key elements in another collaboration. A number of companies in Aalborg East have been considering the question what to do with their production offcuts which are too good to be discarded. Consequently, NB Ventilation, Bobach Stålentreprise and others teamed up with Råt&Godt and an industrial designer to develop a new design line specially adapted to the production capabilities at Råt&Godt. Initially this resulted in a series of tables and lamps. Mikkel Huse from Huse Design designed the furniture specially to make use of the good materials available, while giving the furniture an industrial but classic look that is unique in market for sustainable design today.

Caring for things is worthwhile, that is why we take care of resources.

Christian Helweg, founder and owner

How do we generally work with sustainability?

“Råt&Godt is a workshop in development” helping young people with challenges to transition from unemployment to employment by creating a structured everyday life with positive expectations and collegial community, where desire, skills and readiness are fostered and enhanced by the young people themselves in a constructive collaboration with the workshop employees. The company produces a range of products including custom-made furniture and interiors from leftover and recycled materials in collaboration with the young people in the workshop. All activities in the company incorporate sustainability, either socially or environmentally – often both at the same time. The entrepreneurial environment of Urban City offers a social and creative community for entrepreneurs as well as various events and rental of facilities.

Under the motto: “Because people and materials deserve a second chance”, the company focuses on sustainability and enduring solutions, both socially and environmentally.

Reno-Nord

How are we engaging in symbiosis?

At Reno-Nord, we produce environmentally friendly district heating and electricity from the energy in residential and commercial waste. We supply the surplus heat from our energy plant to Aalborg Utilities, which distributes it through the city’s district heating network. Together with Nordjyllands Power Station, we supply more than half of the heating demand in Aalborg Municipality.

In collaboration with the company owners, we have strived for many years to extract recyclable waste from incinerable waste. This initiative is now being further strengthened by the agreement of the climate action plan for the waste sector. We expect to continue supplying a significant portion of the heat demand to the Aalborg Utilities district heating network, as the spare capacity that can arise from sorting recyclable waste can be used for energy production with green fuels such as garden waste – or waste from other areas in Denmark, where dilapidated incinerators are being decommissioned.

How do we generally work with sustainability?

Every day, we ensure environmentally sound treatment and disposal of the waste we receive from the North Jutland municipalities, companies and private individuals. The waste is incinerated in a modern energy plant with effective flue gas treatment that both protects the environment and generates heating for Aalborg Utilities district heating customers.

 

Up to 2025, the area around Reno-Nord will be expanded to facilitate the establishment of North Jutland Resource Park. The site, which is being established in collaboration with Aalborg Utilities, includes a new modern recycling depot for residents of the city and a resource hall for handling and storing the various forms of waste set aside for recycling. In that way, we can also identify any need for adaption of our existing waste energy plant, thereby matching our future needs.

What is Industrial Symbiosis?

The sharing of surplus resources, such as materials, energy or by-products between two or more companies. It can include the sharing of materials, logistical solutions, facilities and expertise.

Part of the North Jutland network

North Jutland has a strong tradition of collaboration and resource efficiency. In North Jutland it is just called common sense. The local business networks ensure cohesion, and the companies drive each other to be stronger and better. Strong actors within the companies, both ports, the university, municipalities and utilities, support corporate collaborations to manage resources and increase competitiveness. Regional infrastructure affords excellent connections by both land and sea, rail for freight transport and flexible business solutions. Examples of strong initiatives that support sustainable transition can be found throughout North Jutland. The ports of Hanstholm, Thyborøn and Hirtshals are at the forefront of a large state-funded project to ensure source sorting of ship waste, so that it can be recycled. Hydrogen Valley and a strong position on Power to X in the region ensure the development of technologies, methods and collaborations within hydrogen, methanol and green fuels. Foresighted district heating plants are actively working to include surplus heat from industry into the composition of district heating, especially in the Mariagerfjord area. Currently, Port of Aalborg has a new sustainable business area on the drawing board that focuses on synergies between companies from the start. Upon moving in, companies should be able to benefit from each other locally through e.g. value-creating collaborations, potentially with already established companies in the area.

This shall ensure optimal conditions for new business models, resource flows between companies and opportunities for connecting to green infrastructure, such as district cooling from the nearby groundwater reservoir. A test centre is planned for a wide range of green solutions, supported by the local business environment and joint initiatives such as Green Hub Denmark.

Your company can avail of guidance on establishing in the sustainable business park, sustainable action plans, calculated environmental impacts and specific help with collaborations or sustainable optimisation through Industrial Symbiosis North. If you want to know more about the different options, you can read more under the section “Join us”.

Effects

Participating companies can derive beneficial environmental and economic outcomes from the collaborations regardless of size. The effects are preliminarily described in the project Sustainable Synergies and apply to small and medium-sized companies. On average, each company saves 264 MWh, which corresponds to the annual energy consumption of 8 households. On average, the companies can prevent 800 tonnes of CO2 emissions, equivalent to the annual CO2 emissions of 100 Danes. Companies that send their surplus resource to another company typically save on waste management costs. The company receiving the surplus resource can in turn save on materials procurement costs. The typical value of a resource exchange symbiosis is between DKK 30-50,000 per year for a small company.

Moreover, companies can develop new products and reach new markets and customer groups, if e.g. residual materials can be processed through the collaborations. The average value of such a symbiosis is far greater – two smaller companies can expect in Sustainable Synergies DKK 1-2 million annually.

In addition, the symbiosis benefits the companies through an improved image, capacity and competence development, along with an enhanced corporate culture and attitude to work in the company. Social benefits and job creation are an additional effect of industrial symbioses. For larger companies, the work of symbiosis is applicable to Environmental, Social and Governance, CSR, and Global Reporting Initiative standards. Additionally, it secures future opportunities for insurance, financing and loans, as the financial sector is also moving in that direction.

The mapping framework

The symbioses on the map above have been developed over a number of years, either by the companies themselves or in collaboration with the Network for Sustainable Business Development North Denmark (NBEN), Business Network 9220 or through the EU project Sustainable Synergies - a close collaboration between the Danish Centre for Environmental Assessment at AAU, Port of Aalborg and House of Energy, the then energy cluster. That project was chosen by the Danish Business Authority as Denmark's best Regional Fund project in 2020 in the Green Europe category.

The initiative to showcase the green business collaborations through Industrial Symbiosis North stems from several partners. The Environment ++ collaboration between the Port of Aalborg, AAU and Aalborg Municipality, Aalborg Utilities and RenoNord laid the groundwork for the initiative.

Today, Green Hub Denmark also conveys the story further, and new collaborations are constantly being created. Symbioses in North Jutland are far more extensive than the map shows. The symbioses shown have either exchanged materials at least once, or are in development. They have all been created via Sustainable Synergies or mapped in connection with Environment++.
