Turning waste into resources

All human activity creates waste. However, waste can also be a valuable resource. Excess agricultural produce, fish waste, manure, wastewater sludge, household, and restaurant waste are all perfect raw materials for production of biogas.

Biogas can be upgraded to pure biomethane (Renewable Natural Gas), which can be compressed and used as a low carbon vehicle fuel (CNG, RNG, CBG). It can also be injected into the natural gas grid, providing renewable energy to both homes and businesses. Biomethane can even be liquified to bioLNG (LBG), providing low carbon fuels for the heavy transport sectors on land and at sea.
