In the future, wastewater treatment plants can have a broader function by being converted into biorefineries.

All of the world's wastewater treatment plants produce large quantities of sewage sludge, used today to produce biogas. In the future, treatment plants can have a broader function by being converted into biorefineries for the production of everything from biogas to different new materials.

Researchers - Resource - Recovery - University - Borås

Researchers in Resource Recovery at the University of Borås, Sweden, plan to validate a new concept in which they produce and extract fatty acids using membrane bioreactors, which in turn are used to produce the substances acetic acid and hydrogen.

Today, food waste and sludge from wastewater treatment plants are being used to produce biogas, but biogas competes with other energy types, such as wind power and solar energy, which makes the production of biogas alone limiting.

"But with our technology, we can develop a platform so that the treatment plants can be transformed into refineries where different chemical substances can be extracted and used to produce...
