According to Dr. Hoang Sinh Truong from the New Energy Research Center, Hanoi University of Technology, producing electricity from rubbish is transforming rubbish to gas to fuel power generators.
Garbage is kept in close boxes to ferment, disintegrate and release gas. Gas is gathered and directed to extracting and compressed air machines after its water component is taken away. Then, gas is directed to fuel turbines.
Technologies to produce power from garbage have been used for many years, and electricity from mud and garbage is not only new energy but also helps protect environment, according to Prof. Tran Dinh Long, Vice Chairman of the Vietnam Electricity Association.
According to Dr. Truong, it is appropriate now to implement mud and garbage-fueled power plants as related technologies are available and the amount of mud and garbage is huge.
However, Long said, the country needs to calculate economic efficiency in terms of expenses to buy technologies and costs to produce power in order to clarify if investment on garbage electricity is lower than other regenerative sources.
Director of Danang Department of Natural Resources and Environment Nguyen Dieu said the city is conducting research on implementing this clean technology, even when costs are high since the city prioritizes protecting environment.
Many localities and specialists have been interested in utilizing mud and garbages to produce power, yet such projects are still under studies.
Go Cat in Ho Chi Minh City is the first plant producing electricity from rubbish. It generates electricity from rubbish of the two big rubbish dumps, Phuoc Hiep 1 and Dong Thanh, to supply 42 million kWh each year to 20,000 households in the city.
