ECONOMIC & GREEN BENEFITS

 
   
  Watt for watt, biogas energy costs less to produce
  A 2008 report for the California Energy Commission calculated busbar costs for various forms of energy generation, including coal, hydroelectric, thermal and wind power. Biogas was by far the cheapest form of energy to generate. Other studies typically agree: biogas power costs less. Sustainable Alternatives expects similar savings from our Sri Lanka operation.
   
   
  Biogas production helps clean up the environment
  Sustainable Alternatives produces biogas from the organic fraction of municipal solid waste that would otherwise become landfill, or be disposed of in various unsuitable, polluting ways.
   
   
  Generating electricity from biogas reduces greenhouse action
 

Biogas is mainly methane, a highly efficient greenhouse gas (GHG). When burned to produce electricity, methane is converted to carbon dioxide, reducing the amount of greenhouse gas produced by 95%. Biogas conversion to electricity or CNG (compressed natural gas) for use as fuel further reduces the carbon footprint by replacing an equal amount of fossil fuel.

Biogas production from waste (biomass) is carbon-neutral and does not increase levels of greenhouse gas in the atmosphere. The recovery and combustion of one ton of biogas replaces as much as 500kg of diesel fuel and saves 1600 kg of CO2 emissions.

 
  Biogas production can make farming greener
 

Since the by-product of anaerobic digestion is a nutrient-rich organic fertilizer, Sustainable Alternatives can help Sri Lankan farmers reduce their dependence on expensive, polluting chemical fertilizers now in widespread use.

Biogas Production can make transport cleaner and greener.
Biogas upgraded to CNG is a cleaner burning alternative to diesel that can power our busses, lorries and cars, save valuable foreign exchange and make our cities greener.
