Globally, the water industry uses a lot of energy for the treatment of wastewater and its distribution. Subsequently, it can be a large emitter of carbon with detrimental impacts on the planet. Fortunately, sludge produced from wastewater treatment can be digested to produce biogas which can be used to offset fossil-fuel derived electricity, or displace vehicle fuel.
This presentation looks at how digestion, especially enhanced digestion can reduce the carbon footprint of biosolids management, irrespective of the outlet of the biosolids. As well as the production of renewable energy, advanced digestion has other environmental benefits including:
