Recycling plant of the future
Stockholm is one of Europe’s fastest growing metropolitan regions. Since 2000, the country’s population has increased by more than 400 000 people. This growth brings opportunities but also presents major challenges. Demands for housing, energy, infrastructure and waste management are growing, and to meet these demands, new, smart, well-thought-out solutions are essential.
To rise to this challenge, we are working with waste management company Ragn-Sells in Högbytorp, where we will be integrating material and energy recovery in a unique, efficient and sustainable way, generating electricity, heat, biogas and bio-fertiliser from waste products.
The E.ON plant in Högbytorp will contribute to sustainable growth by transforming something nobody wants –waste –into something everybody wants –energy and nutrients.
Creating the circular economy
The recycling plant, which consists of a biogas plant and a combined heat and power plant (CHP), has a strategic location in Högbytorp, northwest of Stockholm. We’re focusing on both costumer’s requirements and societal needs when we provide the basis for the next generation’s sustainable system solutions.
In a circular economy, the lifespan of products is prolonged as long as possible, and waste is transformed into valuable resources.
In the Högbytorp plant Ragn-sells recycle as much as is feasibly possible and we integrate material and energy recovery, and rejected residual products are converted into electricity, heating and biogas.
The combined heat & power plant (CHP)
A CHP plant produces electricity and heat at the same time. In the CHP at Högbytorp the energy from the waste will be put to efficient use.
This is how it works:
- The fuel, which consists of rejected residual products, makes water boil and produce steam.
- The steam drives a turbine that operates a generator which creates into electric power.
- The electricity is fed onto the electricity network.
- The remaining heat in the steam heats the water in the district heating network.
- Cool water is then circulated back and the process starts again.
Organic waste becomes biogas and biofertilizer
The biogas plant in Högbytorp transforms food waste and other organic waste into biogas, a renewable alternative to petrol and diesel. Biogas contributes to reducing the amount of carbon dioxide emission from vehicles.
In the production of biogas, bio-fertiliser, which can be used to enrich the soil in ecological or conventional agriculture, is also produced.
- Organic food
- Organic waste
- Manure and residues
- Biogas (fuel)
Did you know that…
- A bag of household food waste can produce enough energy to fuel a car for 3 kilometers?
- By replacing petrol with E.ON’s Biogas 100, you decrease your carbon dioxide emissions by 90 percent?
- Bio-fertiliser replaces mineral fertiliser, hence reducing the need of virgin phosphorous?
- Thanks to a certification*, bio-fertiliser can be used in organic farming?
