Geelong launches $3M organics composting facility

The City of Greater Geelong has launched a $3 million garden organics composting facility that is able to recover 35,000 tonnes of green organics per year.

Compost from the Geelong Garden Organics Composting Facility will be used on council land, such as parks and ovals, and local farmers. It will see an abatement of 49,000 tonnes of carbon dioxide emissions per year.

Sustainability Victoria provided a $500,000 grant towards the facility on behalf of the Victorian Government.

Projects in regional Victoria have increased the organics processing capacity by 38,250 tonnes per year, with approximately 74,570 households now able to access kerbside collections for food and/or organic waste. With the launch of the new facility, kerbside organics collection services have resulted in an average abatement of 81,621 tonnes of carbon dioxide per year.

Sustainability Victoria CEO Stan Krpan said he was delighted to see the organics facility opened.

“We’ve been working closely with the City of Geelong to enable greater recovery of its valuable resources,” he said.

“Victoria’s population could reach 10 million by 2050, putting pressure to our waste recovery and disposal systems. Taking action now through creating and expanding recycling opportunities will greatly reduce the environmental impact of these resources ending up in landfill, and their economic value being lost.

“This project falls under Statewide Waste and Resource Recovery Infrastructure Plan and the Victorian Organics Recovery Strategy, which plans for all viable recovered materials to be extracted from waste streams before reaching landfill,” Mr Krpan said.

The new Geelong facility is able to provide long term benefits such as processing the council’s green organics, with the potential to process additional organic materials such as food.

“Geelong is one of three large regional organics projects funded by the Victorian Government. It followed Ballarat and Bendigo which all now divert large quantities of organics from waste streams,” Mr Krpan said.

Monash Uni helping farmers profit from food waste

Research has begun on helping farmers transform their food waste into profit while improving their business model thanks to a joint effort from Monash University’s School of Chemistry, IITB (India), the Food Innovation Centre and the agriculture industry.

Monash University is using a holistic approach to ‘biomass valorisation’ to help the industry extract high value components such as antioxidants, oils, pectin and protein from food disposal. Mangoes, pomegranate and pineapple skin, spent coffee grounds and almond ash.

The food waste also extends to fresh produce that is disposed for not meeting the cosmetic standards of supermarkets.

Professor Tony Patti said the biomass valorisation looks at the entire fruit or vegetable, not just what is eaten, which is what currently provides value to the grower.

“The skins, seeds, kernels, leaves and off-cuts were seen as ‘waste’, adding to their disposal costs. These by-products are not waste, but a potential valuable resource, providing several components, identified as being of high market value,” Dr Patti said.

“Monash is working with Australian growers and businesses to diversify the potential market opportunities, including expansion into the pharmaceutical, cosmetic and pet food industries.

“Using this research, food and agricultural companies can tackle costly waste challenges, improve their environmental footprint and create a sustainable business that takes full advantage of growing demand in domestic and export markets for high quality food products,” he said.
