The global push for sustainable waste management encourages the integration of co-digestion methods for sewage and organic waste using anaerobic reactors, promoting environmental and economic benefits for municipalities.
Numerous studies, from laboratory experiments to large-scale implementations, have explored the potential of this co-treatment, but there's still a lack of a unified definition and understanding of co-digestion's impacts.
The review highlights how combining organic waste with sewage treatment could significantly boost methane production and improve sustainability, while also identifying challenges like the need for customized strategies and regulatory support.
