ACT appoints new landfill gas manager

Green energy supplier LGI Limited will deliver gas infrastructure services to all ACT Government landfill sites, under a new 15 year contract with the state government.

Recycling and Waste Reduction Minister Chris Steel said the contract would see an estimated 34,900 megawatt hours captured each year, enough to power 5370 homes.

LGI Limited will deliver infrastructure upgrades at Mugga Lane landfill, including at least four power generators at Mugga Lane, each with the capacity to produce 1.06 megawatts of energy per hour.

Mr Steel said LGI Limited would also install an enclosed flare at the West Belconnen landfill to manage the safe destruction of gas onsite, as the volumes are not enough to provide a commercially viable quantity for sale.

According to Mr Steel, the ACT Government has been capturing landfill site methane emissions since 1997.

“Methane gas is generated when organic waste in landfill decomposes,” Mr Steel said.

“If properly managed, gas can be extracted and used to generate electricity, significantly reducing greenhouse gas emissions at the same time.”

Community consultation open for Canberra WtE

The ACT Government has begun community consultation on waste to energy (WtE) to help develop policy and provide information for stakeholders.

It follows the results of the ACT’s Waste Feasibility Study which found Canberra was unlikely to achieve a recovery rate of more than 80 per cent without some form of WtE leaving 200,000 to be sent to landfill.

The ACT Government has launched a survey to gather community feedback and provide information on the different types of WtE to clearly outline the territory’s position on energy recovery. It has also launched an information paper to outline the challenges and opportunities for the technology in the ACT’s context.

The consultation will inform the ACT Government’s consideration of WtE in the territory.

Currently the ACT has a target to divert 90 per cent of waste from landfill by 2025 and has implemented a container deposit scheme to also improve the territory’s waste diversion rates.

WtE processing facilities are already in use in the ACT with methane gas captured at the Mugga Lane and West Belconnen landfill facilities used to power around 3000 homes.

The ACT has also set a range of targets to 2020 for secure and affordable energy which involves using clean energy technology.

City Services Minister Chris Steel said in the information paper that a serious conversation about what to do to reach the ACT’s landfill diversion targets is needed and should explore whether WtE is part of the solution.

“WtE technologies sit on a spectrum – not all of these involve burning or heating and some technologies are already in use in the ACT, for example through landfill gas capture at our Mugga Landfill site,” Mr Steel said.

“One of the key recommendations of the Waste Feasibility Study was the development of a WtE policy in the ACT to provide certainty to industry and the community about whether WtE has a role in the nation’s capital.

“As the Minister for City Services I want our community and industry to be partners in co-designing a long-term, informed and evidence-based policy vision for WtE in the ACT.”

The community consultation period will close on 29 November 2018.
