"By providing an additional 14% of renewable energy from an existing resource it also takes a further step towards the circular economy objectives recently agreed in Davos." Around 190 UK wastewater sites now produce biogas to generate electricity which is used on site or exported to the national grid. To maximize the efficiency of this form of generation Veolia's team has developed an existing technology, used in the processing of food waste, to increase the quality of the biogas and derive more renewable electricity and heat. According to Veolia, the fully automated system accurately tracks biogas quality parameters to treat the sludge, and this process results in an 80% reduction in H 2 S, helping increase the output and maintain the efficiency of connected downstream energy plant.
