Following Tianjin Shuanggang and Qingguang garbage incineration and power-generation projects, Shuangkou garbage power-generation plant was put into operation in 2008, which symbolizes the scientific disposal of urban household garbage in Tianjin.
Located near Shuangkou garbage landfill site in An’guang Village, Shuangkou Town, Beichen District of Tianjin, Shuangkou Garbage Incineration and Power-Generation Plant has brought in from the United States four Caterpillar gas engine generators with 5,520 kw installed capacity. The first-phase construction of the project, which has been finished, witnesses one gas engine generator on stream, with the annual power generation reaching 8 million kwh, and connected to the North China power grid.
Situated in Jinnan Economic Development Zone of Tianjin, Shuanggang garbage incineration power-generation plant is the first such plant in Tianjin and the biggest one in China.
What meet people’s eyes, when they first step into this plant, are the clean roads and neatly trimmed trees and mowed lawns. Nobody believes that such a beautiful and quiet place is a garbage disposal plant, where hundreds of garbage transportation vehicles come in and out and 1,200 tons of garbage are disposed here every day.
By incinerating garbage, this plant generates powers for homes and factories. The facility effectively solves the garbage pollution problem in Tianjin. Together with the urban garbage disposal facilities, it forms a garbage decontamination system which enables the decontamination rate of urban household garbage in Tianjin rise to 81 percent.
At present, the daily household garbage generated from Heping, Hexi and Jinnan Districts amounts to about 420,000 tons, accounting for up to one fourth of that from all 18 districts and counties of Tianjin. All the garbage now is sent to Shuanggang Garbage Incineration and Power-Generation Plant for treatment and power generation.
Currently the Shuanggang garbage incineration plant disposes 1,200 tons of garbage per day, with the yearly decontaminated, recycled and reused household garbage amounting to 400,000 tons. That capacity can generate as much as 101 million kwh of electricity for power grids annually. All the operation indicators reach historical record.
According to Shuanggang Garbage Incineration and Power-Generation Plant, the harmful gas produced from household garbage incineration in the plant is properly disposed, meeting European Union emission standard through adopting the advanced smoke-purification technology in the process of power generation. The traditional ways of disposing garbage by land-filling and dumping in the open air, which severely damaged the air and environment, have been replaced.
In addition, following the circulative economy principle of “reduce, recycle, and reuse”, this plant burns garbage to generate power, with its remains to make bricks and waste heat to provide heating service for household. The only emission is steam. In this way, a complete circulative economic chain takes shape.
Situated in Beichen District of Tianjin, and invested by Tianjin Like Environmental Protection Co., Ltd., Qingguang Garbage Incineration and Power-Generation Plant incinerate garbage to generate power. With two power generators with the installed capacity of 6,000 kw each, the designed garbage disposal capacity per day reaches 600 tons.
Cities in China are now confronted with the headache of garbage pollution across the country. Generating electricity from household garbage not only solves the problem of household garbage disposal, but also benefits the environment. It also helps save energy.
During recent years, Tianjin, guided by the outlook of scientific development, actively meets the call of resources conservation and construction of an energy-efficient and environmental-friendly society. Garbage power generation is a new trial for Tianjin, a veteran industrial city, to crack the hard nut energy constraint and environmental pollution. At present, garbage power plants can only be found in some economically developed municipalities and provinces such as Beijing, Shanghai, Tianjin and Zhejiang.
