Sludge is the solid waste material, primarily organic in nature which settles out in the residential/municipal wastewater treatment process. When the dewatered and dried sludge undergoes anaerobic digestion, it generates biogas (mostly Methane) which can be collected and used as a source of renewable energy.
The local government is responsible for ensuring that the anaerobic sludge digestion takes place in an efficient manner and waste to energy conversion is emphasized. Therefore, Proper planning, implementation and regulation techniques are required for the anaerobic sludge digestion, not only for proper disposal but also to generate energy in the process.
