The prototype Barton Engine fits inside a shipping container and, its proponents say, could be attached to businesses to take biowaste and transform it into portable energy supplies that power the business producing the waste.

“The advantage of having an engine that can be efficient and small is that you can put the generator where it’s required and where electricity is being used,” Andrews said.

As the Albanese government’s legally binding 2030 emissions reductions targets inch closer, the independent Climate Change Authority has increased pressure on the government and every sector of the economy to reduce emissions.

The authority, led by former NSW treasurer Matt Kean, on Thursday outlined its recommendations on how the six highest emissions-producing parts of the economy should reach net zero by 2050.

It found managing Australia’s waste – particularly organic material in landfill, which produces methane that accounts for about 75 per cent of emissions from the waste sector – would be crucial in limiting the dangerous release of greenhouse gasses.

Emissions from sewage systems, biological (including medical) waste, and thermal waste treatments from incinerators comprise another 20 per cent of emissions from waste, the report said.

“A mix of technologies for the processing of organic waste will be required, and these are likely to consist of composting, anaerobic digestion and combustion of waste to generate energy,” the report found.

The Victorian government has thrown its support behind waste-to-energy projects, and announced in July it would contribute $8 million to 24 projects, which it says could boost the state’s renewable energy capacity by 6.82 megawatts, which is enough to power 3410 homes with renewable energy.

Yarra Valley Water in April announced a new $48 million Lilydale facility would start accepting commercial food waste from as early as 2025, using “digesters” rather than a gasifier or incinerator process, to break down the food and create biogas.

The NSW government has banned the development of thermal energy from waste facilities across greater Sydney, with limited exceptions. Waste to energy projects are instead limited to four precincts: around Parkes, the Richmond Valley, the Southern Goulburn and West Lithgow.

Capricorn Power, which has a patent pending on its Barton Engine, co-funded the pilot project with the Advanced Manufacturing Growth Centre, and hopes to secure investment to push its engines into the market.
