High population growth and urbanisation is greatly accelerating consumption rates in Asian cities, leading to a significant increase in waste generation. Reducing the quantity of organic waste has a vital role in abating methane emissions and mitigating climate change.
Generating biomethane from biodegradable waste can assist by alleviating the escalating environmental burden of waste in Asian cities and can thereby result in sustainable waste management.
As economic growth induces higher demands on energy production in Asia, conserving fossil fuel resources is becoming increasingly imperative. Extracting and mining fossil fuels places a heavy burden on land resources including the risk of land contamination. The production of liquid biofuels also places pressure on land resources. For example, the cultivation of crops, such as palm oil in South East Asia, to produce biodiesel, results in vast loss of forest and peat land through land conversion practices.
The use of organic waste to produce biomethane as a vehicle fuel is a renewable energy source and eliminates society’s reliance on fossil fuels for transportation. Manufacturing biomethane is environmentally benign, having little impact on land resources with production plants located on land already occupied by existing landfill, thus avoiding any additional use of land.
