Waste to Energy and Fertiliser

The cattle colonies outside Karachi house around 1 million cattle. Most livestock farmers are small holders who discharge untreated effluent into the drains and coast, resulting in widespread damage to local environments. The Landhi waste to energy project will capture this waste and digest it, creating methane gas for power generation as well as organic fertiliser. The project will also generate much-needed employment in this poor area.

Ann McLean and Anthony Woods undertook field studies in the project site to gather technical, social and financial information necessary to compile a detailed pre-feasibility study for the Asian Development Bank, under the PREGA program. The pre-FS reviewed the sectors involved, nature and scale of the waste resource, the carbon credit/CER implications, the scope for power generation and fertiliser sales, social and environmental benefits, and the investment requirements to complete the project. The report was accepted by the ADB, and the project has progressed towards attracting commercial investment.
