Every year Australia produces enough sewage, agricultural and processing residuals to power more than 1 million homes. Utilitas biogas plants safely and reliably capture and utilise energy and nutrient from this organic waste that would otherwise typically be disposed of to the environment at a cost.
Biogas (mostly methane) from the natural biological treatment (anaerobic digestion) of wet organic waste and wastewater can be used to generate reliable, continuous electrical power. Biogas can also be directly used to displace other fuels in boilers and burners or “upgraded” for natural gas grid injection (Biomethane), liquefied at low temperatures (BioLNG) or compressed at high temperatures (Bio-CNG) for transport fuels.
Utilitas has mapped the “biogas hotspots” across Australia. Growing demand for food, increasing energy costs and supply risks are the main drivers of the emerging biogas industry.
Elsewhere in Asia, the Middle East and Africa are also increasingly looking towards a biogas energy future, China for example, has a target to have 300 million rural residents using electricity generated from biogas by 2020.
The Australian biogas industry is now starting to evolve as an exciting new energy segment. A joint Deloitte Access Economics/QUT study predicts bio-refining in all its forms can contribute more than $1.8 billion in gross state product to Queensland and create up to 6640 jobs. The demand for sustainable and cost-effective petrochemical replacements and other ‘green’ chemicals is fuelling a new wave of advanced technologies.
