Changsha New CWI Environmental Technology Co., Ltd.
In 2014, Changsha New CWI Environmental Technology Co., Ltd. constructed the comprehensive utilization of landfill gas project in qiaoyi landfill site with a total investment of 70 million yuan. The project includes the operation, gas collection and on-site management of the landfill in changsha solid waste treatment field. The first phase of the power plant was connected to the grid in 2005, with a total installed capacity of 14MW, generating 270,000 kilowatts per hour per day and more than 400,000 cubic meters of landfill gas per day, reducing carbon dioxide emissions by 700,000 tons per year, and generating more than 500 million kilowatts per hour.
It is planned to expand a 14MW capacity project, which is expected to be connected to the grid and generate electricity in the middle of November 2018. After the expansion, the total installed capacity will reach 28MW (22 units), generating 460,000 KWH/day and treating 256,000 KWH/day of landfill gas, essentially, realize the comprehensive utilization. The establishment of the project not only greatly reduces the potential safety problems of landfill gas to landfill site, but also improves the surrounding environment of the landfill site.
