Dong uses enzymes to process mixed MSW for biogas production and material recycling (NL)


A new technology that uses enzymes to treat mixed Municipal Solid Waste (MSW) to recover the organic fraction for processing in an anaerobic digestion facility, has been unveiled by Dutch energy utility, Dong Energy. According to Dong, the technology, dubbed ‘REnescience’, treats ordinary unsorted MSW and industrial waste similar to MSW using enzymes to convert biodegradable material in waste into liquid biomass (bioliquid). The biodegradable material can thus be separated from the solid and recyclable fractions of the waste, while the bioliquid is said to be highly suitable as feedstock for biogas production with a high biogas yield, enabling either efficient energy production or upgrade to natural gas.
