Circular Economy

Our biogas systems demonstrate the effectiveness of the ‘circular economy’ using indigenous technology and materials to treat waste and produce clean energy.

1.  Waste treatment: Reduces Chemical Oxygen Demand in waste waters by about 90%.  Stabilises solid wastes, reducing odours and producing a usable soil conditioner product for reuse of the resource. Avoids smoke and particulate emissions from burning fossil fuels, biomass and municipal waste.

2.  Clean energy: Delivers clean and renewable biogas for industry and power generation.  Easily upgraded to produce biomethane which is a carbon negative replacement for natural gas and ideal as a transport fuel -vehicle fuel that is ready for injection to gas pipeline system.

3.  Climate change: Captures methane a Greenhouse Gas with 28x Global Warming Potential of CO2.  Generates >20x the CO2 equivalent emission reductions and 4x electricity of an equivalent installed capacity of wind or sola photovoltic.

4.  Social impact: Provides good quality jobs for graduates and technicians in rural communities.


Sustainable Development Goals

“In Southeast Asia, with its large agriculture sector, no other source of renewable energy comes close to biogas in terms of contribution to the Sustainable Development Goals” – Des Godson.

1.  Wastewater treatment: Our biogas systems reduce Chemical Oxygen Demand of agro-industrial waste water by approximately 90%, reducing the risk of contamination of water bodies.  Helps to achieve SDGs 6 Clean Water and Sanitation & 14 Life Below Water.

2.  Climate heating: Our biogas systems are designed to capture CH4 (methane) a Greenhouse Gas with 28 times the Global Warming Potential of CO2.  Helps to achieve SDG 13 Climate Action.

3.  Renewable energy: Biogas is a flexible fuel. It may be used to produce heat, electricity and / or Compressed Biomethane Gas. Helps to achieve SDG 7 Affordable and Clean Energy.

4.  Rural development: The production of biogas provides employment and promotes economic development in rural communities. Helps to achieve SDGs 1 No Poverty, 8 Decent Work and Economic Growth & 10 Reduced Inequalities.

5.  Circular economy in action:  We treat waste at source and produce clean energy using simple but innovative technology. Helps to achieve SDGs 9 Industry Innovation and Infrastructure, 11 Sustainable Cities and Communities, and 12 Responsible Consumption and Production.

In addition, our biogas systems make a positive contribution to the SDGs relating to zero hunger, good health and well-being, education, gender equality, life on land and partnerships for the goals helping to achieve SDGs 2, 3, 4, 5, 15 and 17.

The multi functionality of biogas and its positive impact on the Sustainable Development Goals provides a strong justification for carbon emission offset buyers to prefer emission reductions from biogas projects over other emission reductions.

Given the strong positive contribution of biogas to the Sustainable Development Goals, we believe that biogas production from agricultural waste should be the first priority renewable energy in Southeast Asia and the first choice for carbon emission offset buyers.
