Over 80% of Local Governments (LGs) worldwide are responsible for residential solid waste collection within their territory [1]. However, solid waste management is a great challenge from an organizational, technical, and financial perspective, and municipalities are often overburdened by the task. This solution focuses on the processes which the LGs can undertake to promote sustainable waste management in their communities through a long-term approach.
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.
