The dawn reported that a plant set up in Sanghar in Sindh by the United Nations Environment Program is generating 50 cubic meters of biogas, sufficient to energize 20 households, in addition to producing 200 kilogram of liquefied and 150 kilogram of solid fertilizer a day by using 400 kilogram of agricultural waste.

The UNEP announced that its Japan based International Environmental Technology Centre had taken up the project to convert agricultural waste into clean, sustainable energy. The project was completed at a cost of PKR 2 million.

A survey carried out by the IETC and the Mehran University of Engineering and Technology found that 2.5 million tonnes of waste, comprising wheat and canola straw, cotton stalks, cotton gin waste, sugarcane tops, bagasse, rice straw and husks, and banana plant, was produced in Sanghar district.

A subsequent calculation found that the energy potential of the available waste was equivalent to 1.07 million tonnes of firewood or 910 million units of electricity. The converted waste could meet the energy demands of roughly 400,000 households.

It was learnt that while 20% of sugarcane tops was being fed to animals, the rest was being burnt in the fields along with the entire banana plant waste and 70% to 80% of rice straw. The Sanghar Sugar Mills agreed to provide the land and funds to build the plant.
