Sewage sludge valorisation


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.
