Cleaner Vietnam - Biogas from Cassava

Vietnam is one of the 10 biggest producers of cassava in the world. Its manufacture involves generating large quantities of wastewater. The starch in the latter ferments and creates methane - a highly toxic climate killer.

The Daklak Tapioca Factory in central Vietnam is now collecting the gas as an energy source and using it to operate the facility. The process helps reduce coal consumption, thereby cutting greenhouse gas emissions.
