Soil-Concept is developing a procedure to transform sewage sludge compost into gasENERCOM is really a concentrate of technology. The idea of ENERCOM is thus to take sewage sludge treatment and recovery several steps further. The compost is obtained by mixing pre-treated sewage sludge with plant waste. Soil-Concept was founded in 1996 and has been collecting sewage waste in Diekirch since 2000. Today, about 35% of Luxembourg’s sewage waste goes into Soil-Concept’s big silos that are able to process 12,000 tonnes of the mix, which includes plant waste.
