In this study different organic fractions of municipal solid waste (OFMSW) were used as raw material in a novel treatment process that combines thermal hydrolysis (TH) pretreatment with anaerobic digestion of the solid fraction and photo-fermentation of the liquid fraction. Specific phototrophic activity tests were performed using a mixed culture of purple phototrophic bacteria (PPB) that consumed up to 80% of the soluble organics. PPB was capable of producing polyhydroxyalkanoates, bioH2 and single-cell protein, apart from methane.
Highlights of the DEEP PURPLE publication:
- Transformation of biowaste by purple-phototrophic bacteria-based treatment
- Time had no impact on overall performance in thermal hydrolysis pretreatment.
- 15% of total solids transformed into high added-value products.
- High biomass yield achieved during photo-fermentation.
