Trisun plans green power for Vietnam

Australia's Trisun Energy has set a major investment target to build power generating waste treatment plants in Vietnam, as the country looks to 'green energy'.

Sydney-based Trisun Energy Co has set a goal of building up to 20 electricity generating high energy waste treatment plants capable of replacing coal-fired plants in Vietnam.

Trisun Energy recently secured a $US520 million treatment plant outside Hi Chi Minh City, capable of consuming 40 per cent of the daily land fill waste.

The project, cleared by the Ho Chi Minh City's People's Committee, follows completion of a comprehensive study in 2016, after a bidding process launched back in 2011.

Trisun Energy says its long-term goal is to provide Vietnam with a "stable, non-harmful source of clean and green energy," according to Vietnam media and the company's official website.

The waste treatment plants use electrical energy and high temperatures created by an electric arc or plasma gasification.

The plant will be capable of burning up to 3,000 tons of garbage of day - the equivalent of more than 40 per cent of the city's waste.

Trisun Energy says the electric arc breaks down the waste into gas and solid waste (slag) in a device known as a plasma converter.

"The process has been intended to be a net generator of electricity, as well as reducing the volume of waste set to the land fill," the company said.

"The high temperatures, the low volume of gas emissions and the dissociation of organic compounds, gaseous emissions from plasma waste processes are much cleaner than other kinds of gasification," Trisun said.

Trisun says the next step is to build a second plant in Hanoi, "and spread to other regions and locations throughout the country".

The goal is to build "12 to 20 plants" in the next five to 10 years, with the energy generated capable of replacing that produced by a coal-fired plants.

Vietnam media said prior to Trisun Energy entrance companies involved in solid waste treatment in Ho Chi Minh City included the US backed Vietnam Waste Solutions (VWS), disposing 5,000 tonnes of waste per day.

But the VnExpress International said in 2016 Ho Chi Minh City awarded state-owned Cienco, which also provides environmental services, was given the go ahead to build the first waste treatment plant capable of generating power.
