Sewage sludge becomes fertiliser.

The European Union has about 50.000 municipal and industrial waste water treatment plants (WWTPs) whose waste water treatment technologies tend to have a very negative environmental impact and generate a lot of greenhouse gases (GHGs). WWTPs use a lot of energy to clean water and generate over 11 million tonnes of sewage sludge waste. The current main disposal routes for sewage sludge (landfilling, incineration, agriculture, composting) are causing a big environmental problem. The ECO-BIS project offers a new solution which is not yet on the market. Its two main aims are to make the waste water cleaning processes of industrial and municipal WWTPs more ecological and efficient and to recycle sewage sludge waste into a high value added carbon-phosphorus fertiliser.

The Eco-bis technology was developed by Greenlife, which now coordinates the project. The technology is very efficient in pre-cleaning of waste water and dewatering of sewage sludges. The key feature of this innovative technique is the pyrolysis system, which converts the energy-rich and dewatered sewage sludges into a high value and marketable fertiliser. All these systems use less energy than conventional techniques and reduce CO₂ emissions. With the help of the Eco-Innovation project we establish three ECO-BIS plants in Austria, Hungary and Slovenia and recycle sewage sludge into a high value biochar material.
