Dak Lak (VNA) – The pyrolysis technology applied in coffeeproduction in the Central Highland province of Dak Lak has shown efficiency inreducing greenhouse gas emission and improving product quality, a survey of theUnited Nations Industrial Development Organisation (UNIDO) said on November 7.
Pyrolysis is thermochemical decomposition of organic material at elevatedtemperatures in the absence of oxygen. Pyrolysis of coffee husks creates heatwhich can be used to dry coffee beans and leaves a solid residue, which is richin carbon content and can be used to improve soil fertility while minimisingCO2 emissions.
Three years ago, Viet Hien Company Limited in the province was the recipient ofthe pyrolysis technology transfer under the “Minimisation of Industrial Wastefor Low Carbon Production” project funded by the Swiss Federal Department ofEconomic Affairs through the UNIDO. Besides disseminating the pyrolysisequipment in Dak Lak province, the firm successfully transferred the technologyto Brazil.
Swiss Ambassador to Vietnam Maser Mallor lauded the efficiency of pyrolysistechnology used in coffee production in Vietnam, saying that it helps lowergreenhouse gas emission while saving electricity and water.
She affirmed that Vietnam is among prioritised countries in the SwissGovernment’s economic cooperation programme, and her country will continuesupporting Vietnam to improve its capacity in environmental protection andresponse to climate change.
According to the UNIDO, during 2013-2017, the project backed clean production at16 rice and 10 coffee processing plants, saving 1.08 million kWh per year,equivalent to more than 80,000 USD, and cutting 621 tonnes of CO2 eachyear.-VNA
