HAINAN PROVINCE BIOGAS
With a tropical climate, exotic vegetation, long sandy beaches and a diverse ecosystem, Hainan Island, the largest island in Hainan province, is affectionately known as the "Hawaii of China".
Home to the Sanya E-Prix, Hainan province is the location for this Gold Standard (GS) rural methane recovery and combustion project, which is helping the region to transition from relying on fossil fuels for energy production to generating their own renewable biogas. The project aims to help farmers in 20 provincial townships to build anaerobic digesters for degrading organic waste, including pig manure, into biogas.
The project reduces greenhouse gas (GHG) emissions in two ways; firstly, by changing manure management processes it can prevent harmful methane (CH4) emissions into the atmosphere and secondly, the biogas can be used in place of the coal previously depended upon for household heating and cooking.
It is estimated this this project can save 53,000 tonnes of CO2 per year, while contributing to 6 of the 17 Sustainable Development Goals (SDGs) (1, 3, 7, 8, 12, 13).
