Speaking at a press conference on August 26, the department’s director Nguyen Toan Thang said the plants are expected to start running on a trial basis in September next year, and process 50 percent of the city’s solid waste to produce power.

They will come up at existing solid waste treatment facilities in Cu Chi district run by the Tam Sinh Nghia Investment Development JSC., Vietstar Joint Stock Company and Tasco Joint Stock Company.

“They would help ensure a healthy living environment and are needed for the city’s green and sustainable economic development.”

Using advanced technologies to generate electricity at waste treatment plants is in line with the city's orientation on urban solid waste management.

The city wants waste-treatment facilities to use advanced technologies to generate electricity from garbage instead of burying it in landfills. It aims to reduce the volume of buried waste to 20 percent by 2025.

Burning and burying of garbage are two methods that have an adverse impact on the environment.

The city generates around 9,000 tonnes of solid waste daily, of which 72.5 percent is buried and the rest is burnt, recycled or used to produce fertilisers.

Advanced technologies will convert waste into electricity and produce by-products that can be recycled.

The power generated would be used to run the plants and the excess would be transmitted to the national grid, Thang said.

“The projects will help reduce the volume of buried waste and greenhouse gas emissions, and control odours and leachate leakage from waste.”

Ngo Nhu Hung Viet, Director of Vietstar Joint Stock Company, said the power plant would use German technology and have a daily waste processing capacity of 2,000 tonnes in the first phase by 2020 and 4,000 tonnes in the second phase by 2021.

“It would help HCM better protect the environment and to become a more modern city,” he said.

Groundbreaking for the construction would be on August 28, he said.

Thang said the municipal People’s Committee has directed relevant agencies to quickly complete the legal procedures for the three plants.

The city will call for bids to identify investors for two more similar power plants next year.
