We really fire up the sludge
Thanks to our thermal recycling activities, we reduce annual demand for fossil fuels by over 100,000t and generate 70,000 MWh of energy
Sludge is a versatile resource that is generated by the treatment of wastewater. This recyclable material is particularly interesting as it contains phosphorus – a vital element for all living organisms - as well as other nutrients and organic substances. Moreover, in its dried form, sludge has an energy content similar to that of brown coal. As market leader, we create natural closed cycles: by recycling it so it can be used on the fields of local farms, by thermally treating it to generate energy and by recovering and recycling phosphorus.
Energy recovery means that the calorific value of the sludge is used to generate energy – whilst eliminating pollutants at the same time. Using the material as a secondary fuel in power stations and sewage sludge incineration plants is an intelligent and carbon-neutral way to produce energy that also helps to cut demand for fossil fuels.
An ever increasing number of power stations are using this intelligent and carbon-neutral way to produce energy
Sludge used on farmland is an eco-friendly and sustainable way of replenishing the nutrient, humus and mineral content of soils
Using sludge as a fertiliser on farmland is a sustainable form of recycling as 60% of all phosphate in Germany is used by agricultural businesses to fertilise their fields and a further 20% for producing animal feed. Sludge is an extremely important supplier of nutrients and humus and helps to conserve our planet's natural resources.
We close material cycles by recovering phosphorus – a resource that it becoming more and more scarce – from the wastewater and using it as a fertiliser
The sludge and organic structural elements undergo a biological treatment process to produce high quality composts and soil substrates which can be used for gardening and landscaping as well as for redeveloping land. The composting method is an environmentally friendly process which generates a final product that is rich in nutrients and ideal for improving soils.
