Energy Production from Kitchen Waste: Five MWM Gas Engines in China Produce Sustainable Power from Biogas
Mannheim, September 20, 2022
China’s population is growing, and so is the amount of waste that accumulates. In two innovative waste utilization plants, three MWM TCG 2020 V20 and two MWM TCG 2020 V16 gas engines help to make good use of this waste. Thus, the MWM gas engines generate power from the biogas gained from the waste. The generated power is used for the operation of the waste utilization systems, and the excess power is fed into the public grid.
Largest Environmental Protection Project for the Utilization of Kitchen Waste in China
In December 2021, the Likeng wastewater treatment plant—currently China’s largest environmental protection project for the processing of waste—went live. On average, the plant processes about 1,000 t of kitchen waste a day. The plant is operated with three MWM TCG 2020 V20 gas engines that were delivered by the MWM distributor Beijing Pauway Energy Technology Co., Ltd., which also prepared the plans for the project’s energy systems. The gas engines deliver an output of 2,000 kW each. Kitchen waste contains a lot of organic substances, from which biogas is gained in an anaerobic digestion process. After cleaning and post-treatment, the biogas is used as fuel for the MWM gas engines, which produce electricity.
The Likeng wastewater treatment plant processes about 350,000 t of kitchen waste a year. The annual power generation is estimated at 48 million kWh. Through this sustainable form of power generation with biogas, the plant’s carbon emissions drop by more than 15,000 t/year. The generated energy is used for the plant operation, and excess power is fed into the public grid.
Additional Waste-to-Energy Project Planned in Qingdao
In Qingdao, China, kitchen waste will henceforth be used for power production purposes. A power generation project planned by Pauway has been rolled out in a domestic waste utilization park in Qingdao. The new plant is powered by two MWM TCG 2020 V16 gas engines, each of which delivers 1.56 MW. Following the plant go-live, the MWM gas engines will cover the power demand of the waste utilization park and supply any excess power to the public grid. The project will provide the grid with about 25 million kWh of power a year. As a result, carbon emissions will drop by more than 3,300 t/year, and about 666,667 m2 of landfill space for waste can be saved.
The waste utilization park in Qingdao, which Pauway has implemented with MWM gas engines, is a key element of the city’s infrastructure and environmental regeneration. Apart from ensuring the ongoing clean operation of the city, the development of Qingdao’s waste treatment capacity promote the city’s sustainable development with a focus on eco-compatibility and reduced carbon emissions.
MWM TCG 2020 Gas Engine: More Eco-Compatibility, More Economy
The MWM TCG 2020 gas engines are perfectly aligned with the challenges of a dynamic market setting. The gas engines are mainly used for CHP plants in Europe and for biogas worldwide. In the output range from 1,000 to 2,000 kWel, the MWM TCG 2020 gas engines meet the requirements of a broad application spectrum and ensure high efficiency, reliability, flexibility, and eco-compatibility.
