The world’s largest waste-to-biogas conversion plant is gearing up for a grand opening next spring in Northwich, using advanced enzyme technology to handle unsorted domestic waste. Around 15 tonnes of trash per hour – 120,000 tonnes a year – will be sorted at the REnescience plant in a process that will power nearly 10,000 homes, according to Dong Energy, which runs the project. The Danish energy company has invested £60m in the Northwich venture, which will use trash collections by local councils in Chester and Wigan to produce 5MW of renewable energy. Its energy conversion process works by separating organic matter such as paper and foods from other waste streams and then “washing” it free of contaminants using enzymes in a giant reactor.
