Sewage sludge valorisation

Trailer

How it works

aqualia will demonstrate an innovative start-to-end valorisation process in Toledo, Spain. The sludge will first be subjected to pretreatment and anaerobic bioconversion. 

CO2 contained in biogas will be upgraded via bioelectrochemical treatment into alcohol and organic acids: high value chemicals for industrial purposes.

In parallel, a pilot in the Netherlands coordinated by Wetsus will valorise surplus sewage sludge. Pretreatment is followed by a fermentation phase. Green solvents will be used to extract PHA biopolymers.

ITENE will test how they can be processed into bioplastics and biomaterials for packaging.

Thanks to modern, state of the art upgrading processes, numerous biogas plants feed their biogas directly into the natural gas grid after removing impurities and upgrading it to natural gas quality already today. In some cases, biomethane is even sold directly “from the farm” in small CNG filling stations. This proves: natural gas vehicles can run on […]
