Landfills and coal mines are the two largest CH₄ emitting industries in Australia.  Considering the global warming potential of CH₄ (~ 25 times that of CO₂ over a 100 year period), developing a unique technology to mitigate CH₄ emissions is critically important to avoid further ozone depletion in this region. The CH₄, which is simply wasted or unutilized, could be re-routed for industrial production of bio-polymers via biotechnological approaches. However, it requires vigorous laboratory testing, optimization and robust consortia formulation to work with landfills and coal mine cases, especially the former emit high (max. 60 % CH₄) and the later emits very low concentrations (max. 1% CH₄) of CH₄. In our research, we aim to develop robust consortia, i.e. mixed populations of methanotrophs and cyanobacteria, to effectively re-store CH₄ and CO₂ as bio-polymers (ex. Polyhydroxyalkanoates - PHA) in an appropriate bio-reactor design. Merits of this project are: the technology can be extended for any CH₄ and/or CO₂ emitting industries, limit fossil fuel consumption for plastic production, support additional revenue and provide regional employment opportunity. Further, successful implementation allows claiming of Clean Development Mechanism (CDM) benefits for carbon capturing in Australia.
