An agreement concerning a plant to treat methane gas emitted from decomposing trash to produce electricity has been signed by the Hanoi Urban Environment Company, the T&T Joint Stock Company, and three enterprises from South Korea: Sudokwon Landfill, the Korea Engineering Consultant Corp., and Samyoung.

Located at the Nam Son Waste Treatment Complex in Hanoi’s Soc Son district, the plant has total investment of over $13.1 million, funded by the World Bank and South Korea’s Ministry of Environment. It will take some 15 months to build, and once completed is expected to produce 5 MW of electricity annually for 15 years, according to Mr. Le Anh Tuan, Chairman of the Hanoi Urban Environment Company.

The Nam Son landfill is the largest in Hanoi, treating some 4,000 metric tons of trash each day.

According to specialists, trash dumps generate a huge amount of methane (CH4), which, if not collected and treated, will rise up into the air, ten times more in volume than CO2, and create greenhouse gases. But if it is collected and treated, however, it could become a useful energy resource.

The new plant will therefore lead the way in the management of other waste treatment complexes in Vietnam. The government has encouraged projects to generate electricity from waste, and all power produced will be purchased.

Earlier this year, the country’s first industrial waste-to-energy plant was put into operation at the Nam Son Waste Treatment Complex, supplying electricity to the national power grid. Using the latest technology provided by Japan’s Hitachi Zosen C, the plant can treat 75 metric tons of waste and produce around 1.93 MW of electricity each day. The plant cost more than VND645 billion ($28.3 million), with nearly VND472 billion ($20.7 million) coming in the form of non-refundable aid from Japan’s New Energy and Industrial Technology Development Organization.
