Chicken waste biogas-to-energy plant for China

Jenbacher biogas engines from GE Energy have begun powering China’s largest chicken waste biogas-to-energy plant located at the Minhe Animal Husbandry facility near Penglai City in Shandong Province. The 3 MW plant features three of GE’s JMS320 Jenbacher engines, which generate electricity for both the 19,000 m2 complex and for export to the local grid.

The new biogas plant features an anaerobic digester system that consumes 300 tonnes of manure and 500 tonnes of wastewater daily. The resulting digester biogas is delivered to the engines to generate electricity. Residual material in the digester can later be used as fertilizer.

Minhe Animal Husbandry Co. is the biggest stud and meat chicken farm and the industry’s only stock-listed company in China. The company’s 23 stud chicken farms maintain a total of 1.5 million stud chickens and another 3.7 million chickens for meat production annually.

Jenbacher engines can help farm customers overcome the operational and environmental impacts of their operations. By consuming the waste in the digester to create biogas electricity, the technology can greatly reduce the site’s greenhouse gas emissions and dust created by the chicken waste, which in turn helps improve regional air and water quality.

The use of chicken waste digester biogas to generate on-site power also supports China’s national economic goals to promote the use of renewable, distributed energy technologies to improve local reliability and reduce regional greenhouse gas emissions, says GE. Backed by the International Bank for Reconstruction and Development, the project receives financial support through the sale of carbon credits called Certified Emission Reductions (CERs).

One of GE’s four official Jenbacher gas engine distributors in China, Jebsen & Co of Hong Kong, supplied the three biogas engines and engine control equipment for the project.
