We are Australia’s largest producer of renewable energy from biomass.
In addition to raw sugar, our mills generate renewable energy from the biomass they produce while crushing cane. This biomass, called bagasse, is the cane fibre that’s left over after crushing has stripped the sugar cane of its juice.
The bagasse is recycled and used as boiler fuel at our mills. It’s burned at temperatures of up to 800˚C to produce steam, which is either used as heat for the milling process or converted into electricity. This process is called cogeneration.
Our eight sugar mills have a total generation capacity of 199 megawatts, producing 600,000 megawatt hours a year. We create enough renewable electricity to allow for significant quantities to be exported into the Queensland power grid. The electricity we export is enough to power more than 80,000 Australian homes each year.
Three of our mills - Invicta, Pioneer and Victoria - have upgraded cogeneration facilities to increase their export capacity. Pioneer’s cogeneration plant is Australia's largest generator running only on biomass. Surplus bagasse produced in our Burdekin mills during the crushing season is stockpiled on large, specially designed pads at Pioneer to enable the cogeneration facility to continue to operate outside of the crushing season.
