  • Start date

    30 March 2020

    End date

    31 August 2023

  • Project Partners
    Shire of Collie, South West Development Commission


The project involves the design, build and operation of a 1.5 tonne/hour pre-commercial demonstration energy-from-waste (EfW) plant located in the Shire of Collie in Western Australia.


Technologies that convert inedible plant material (called biomass) and municipal solid waste (garbage) into biofuels and biochar can help to reduce carbon dioxide emissions and improve energy security, while diverting waste from landfill.


The EfW plant will use patented grinding pyrolysis technology (the Renergi Process) to convert an estimated 4000 tonnes per year of municipal solid waste, and 8000 tonnes per year of forestry wastes into crude pyrolysis/bio-oil for energy applications, and bio-char for land and other applications.


The project will demonstrate and share lessons on the economic costs and benefits of both small modular scale EfW plants, and larger commercial scale deployments. This includes advantages to consumers and market participants of situating EfW projects within communities around Australia.

Additional impact

Municipal solid wastes, forestry and agricultural wastes will be converted into high-value products such as biochar, biofuels and biocarbon materials while sequestering the CO2 that has already been emitted into the atmosphere.

Renergi installs innovative biomass pyrolysis plant

From start-up inception in 2012 to the verge of plant operation in 2023, ARENA has supported biomass-to-energy company Renergi along its renewable energy journey.
