By capturing gas from wastewater lagoons and converting it into electricity, the Linshu project, located in the Eastern  Shandong Province of China, reduces business-as-usual emissions from entering the environment by converting it into renewable electricity. This electricity is then fed back into the industrial plant for energy thus displacing energy that was previously acquired from fossil fuel sources.  


In China's manufacturing sector, wastewater from production activities is often stored in open lagoons which, due to anaerobic reactions, leads to the release of large amounts of methane. Methane, as a GHG, is significantly more potent than CO2 and by trapping heat is estimated to be responsible for ≈25% of global warming. Finding innovative solutions to deal with manufacturing wastewater is crucial in tackling climate breakdown and maintaining the health of global ecosystems.


The project effectively reduces emissions by displacing energy that would otherwise be supplied to the industrial plant from the burning of fossil fuels. In addition, the implementation of an anaerobic biogas recovery system mitigates methane from entering the environment - thus reducing greenhouse gases in multiple ways. Finally, the projects create employment opportunities, through both the construction and operational phases of the plant boosting the local economy.
