Biogass Renewables uses a process called anaerobic digestion to convert commercial and industrial waste into onsite electricity, heat and clean methane gas. The organic waste streams that feed our plants range from supermarket, kitchen, dairy, vegetable, abattoir and fishery waste, to grain and legume surplus, to ordinary garden waste.
Anaerobic digestion produces large quantities of biogas, comprising methane and carbon dioxide. The cleaned methane fraction can be stored, pressurised and used to generate onsite power and heat, with surplus fed into the electricity grid, or used to power equipment and vehicles.
The digestate by-product of the process can be readily and safely used as a commercial organic compost or fertiliser.
On a case by case basis, anaerobic digestion projects are likely to qualify for carbon credits under the proposed Australian Clean Energy Futures Scheme.
Anaerobic digestion is not a new technology, but it is new to Australia having been standardised and refined through prolific use and development by industry in Europe (particularly Germany) and Britain over the last 15 years.
