NSW Government and Cenagen Clash Over $1B Waste-to-Methanol Plant at Historic Kandos Site

Proposed gasification facility at former cement works faces prohibition under state's energy-from-waste framework

A $1 billion waste processing plant proposed for the historic Kandos Cement Works site near Mudgee is at the centre of a dispute between developer Cenagen and the New South Wales government, with Environment Minister Penny Sharpe arguing the project falls under the state's energy-from-waste framework and cannot proceed outside designated precincts.

Cenagen is seeking to develop the facility at the former Kandos Cement Works — the site that supplied cement for the Sydney Harbour Bridge — using gasification technology to process 450,000 tonnes of rubbish per year that would otherwise go to landfill.

The technology exposes waste to temperatures of up to 1,000 degrees Celsius in a low-oxygen environment to produce synthesis gas. Cenagen says the gas would then be used to manufacture 91,000 tonnes of methanol annually, marketed as a lower-emission alternative to fossil-based transport fuels. The company says the project would be the first of its kind in the world.

However, the NSW Energy-from-Waste Framework restricts thermal treatment of waste that involves energy recovery to four designated precincts: Parkes, West Lithgow, Tarago and Tomago. Kandos is not among them.

In a letter to MLC Stephen Lawrence, Environment Minister Penny Sharpe stated it was "unlikely that the activities Cenagen proposes to undertake would be permitted under the Framework" and that there was "no alternative approval pathway to such activities."

Cenagen chief executive Jason O'Sullivan disputes the classification. "We are not energy-from-waste, we respectfully disagree," he said. "There will be some stage where the difference of opinion will have to be resolved. If and when that arises we are comfortable in our position."

The Environment Protection Authority (EPA), to which Minister Sharpe referred inquiries, confirmed in a statement that "the thermal treatment of waste that involves energy recovery is limited to the four precincts" and that "Kandos is not within an approved precinct under the framework." The EPA noted it met with Cenagen representatives in August 2024 and July 2026, and in each meeting conveyed the view that the proposal would likely be prohibited.

Analysis

Why This Matters

  • The dispute tests the boundaries of NSW's energy-from-waste policy, which explicitly limits thermal treatment to certain areas.
  • If approved, the plant would be a world-first commercial-scale facility converting municipal waste into methanol, potentially setting a precedent for waste-to-fuel technology in Australia.
  • The outcome could affect waste management strategies across NSW, where landfill capacity is under pressure.

Background

The Kandos Cement Works operated for decades before closing in 2011 and has since been demolished. The site's historical significance — having supplied cement for the Sydney Harbour Bridge — adds symbolic weight to the controversy. NSW's energy-from-waste framework was introduced to regulate incineration and similar technologies, directing such facilities to specific regional precincts to manage environmental and community impacts. Cenagen's proposal uses gasification rather than combustion, but the government views it as falling under the framework because it involves thermal treatment and energy recovery.

Key Perspectives

[Cenagen]: Argues the gasification technology is not energy-from-waste as defined by the framework, since it produces methanol rather than directly recovering energy. The company is confident its position will be vindicated if the matter goes to a formal determination. [NSW Government / EPA]: Maintains that any thermal treatment of waste with energy recovery falls under the framework, and that projects outside the four designated precincts cannot be approved. The EPA has twice told Cenagen the proposal would likely be prohibited. [Critics / Skeptics]: Community and environmental groups may worry about emissions, transport of waste, and the precedent of allowing such a facility outside the planned precincts. Some may also question the environmental credentials of methanol production from waste.

What to Watch

  • Whether Cenagen pursues legal or planning avenues to force a formal determination of its classification.
  • Potential amendments to the energy-from-waste framework in response to technological arguments.
  • Community and local council reactions in the Mudgee-Kandos area as the dispute develops.
