Australian companies offer commercial opportunities for potato waste

Four of the largest potato producers in Australia want to convert 100 per cent of their potato waste into commercial benefit through their partnership with the Fight Food Waste Cooperative Research Centre (CRC).

Over the next three years, The Mitolo Group, Zerella Fresh, Thomas Foods International Fresh Produce, The South Australian Potato Company, together with Industry Association; Potatoes South Australia Inc, and the University of Adelaide will invest nearly $1m in this research and development to save up to 100,000 tonnes of potatoes currently going to waste every year.

Chief executive of Potatoes South Australia, Robbie Davis, said that this is a fantastic opportunity for Australia, particularly South Australia as it is the largest potato growing state.

“We are seeing up to 40 per cent of potatoes rejected because they do not meet retail specifications. At the same time Australia is importing 20,000 tonnes of potato starch each year, and it just doesn’t make sense that we’re not using these huge volumes of potatoes for alternative purposes,” she said.

A large focus of this project is the potential development of an Australian potato starch industry which would provide additional revenue for Australian potato companies; potentially $1,000 a tonne for extracted starch instead of the current value of $0-10 a tonne for the waste.

“Potato starch is used broadly across the food industry, for bioplastics and packaging, to coatings and adhesives. We also want to use the waste from the waste, so after extracting the potato starch, there will be further opportunities using the residual waste from this first stage,” said Davis.

The four Australian potato companies that have partnered with the Fight Food Waste CRC are leaders in their industry and recognise the opportunity this represents to the industry.

Professor Vincent Bulone from the University of Adelaide is leading this research project from his world-class analytical centre for complex carbohydrate analysis, Adelaide Glycomics. The project is in line with the University’s industry engagement priority on agrifood and wine.
