Daklak Tapioca Factory produces about 12,000 tonnes of tapioca starch products. The production process results in large quantities of wastewater with a high content of organic substances and the energy required has been generated by burning coal. Prior to the implementation of the project, the wastewater decomposed anaerobic under formation of methane - a gas around twenty times more harmful than CO₂. This methane was able to freely enter the atmosphere.
In the climate protection project, the pond is now covered by a membrane and thus the methane is captured. The recovered methane from the wastewater treatment can be burnt in addition to coal in the existing, modified boilers. Besides the reduction of the greenhouse gases methane and CO₂, the local air quality is also improved by the reduced amounts of coal burnt.
