Manildra Group powers down emissions with cutting-edge cogeneration
Manildra Group, Australia’s largest wheat processor, has overhauled energy use at its Shoalhaven Starches site in Nowra – the world’s largest wheat gluten and starch plant of its kind.
In 2024, the company switched on a state-of-the-art cogeneration plant that replaced coal-fired energy with a cleaner gas-fired system. Backed by $85 million loan from the Clean Energy Finance Corporation, the $250 million investment delivers big results:
Up to 40% emissions cut, or about 300,000 tonnes of CO₂ annually
Steam and power generated from one process
More than 90% of the site’s power now produced on-site
The cogeneration system uses natural gas to power turbines that generate electricity. Heat from those turbines is then captured to produce steam – a critical input for production.

“Our investment in cogeneration has transformed the way we power our Shoalhaven Starches site – reducing up to 300,000 tonnes of carbon dioxide emissions each year. It’s a significant milestone in energy efficiency and emissions reduction, helping us future proof our operations to stay competitive globally.”

Why it matters
Shoalhaven Starches is a global leader and producer in wheat gluten, starches, syrups, ethanol and animal feed. This upgrade keeps the site competitive and sustainable.
However, reliable steam and energy generation remains critical for Manildra Group’s operations, and they continue to rely on natural gas for these energy-intensive processes. Being in a regional location also limits their access to lower-emissions electricity, so ongoing collaboration with government and industry partners is essential to help address these challenges.
As the largest private employer in the region, Manildra Group’s investment in a greener future also safeguards jobs and the future of Australian food manufacturing.
The bigger picture
Manildra Group’s project is part of a broader industry shift. With energy costs rising and emissions targets tightening, food and grocery manufacturers are exploring smart ways to reduce their footprint without compromising on output.
