Local governments all over Pakistan adopt open land fill solid waste management models. In some instances, SWM involves mere collection of solid waste from residential areas and dumping in outskirts of the cities and towns, with zero management of such waste. More recently, creation of SWM companies by Government of the Punjab, has introduced some level of SWM but even this model lacks international best practices in the sector.
Adoption of waste-to-energy biogas projects can not only help manage the SWM effectively, but also provide much needed Bio-Methane for households, CNG for vehicles, LNG for remote areas as well as a sustainable energy source for Electricity Generation locally.
Both, the Wet and Dry Anaerobic Bio Gas Plants offer viable solutions for municipal solid waste management. Since, this waste is predominantly unsegregated with high inorganic content, the treatment of MSW in Pakistan, Wet Anaerobic Plants are a costly proposition given the technologies involved for segregation add up to over all costs. However, industrial scale Dry Anaerobic Plants are a viable solution to safe and climate friendly disposal of MSW in Pakistan.
