New research has revealed using food waste to create commercial chicken feed would not only save the Australian poultry industry an estimated $500 million a year, but it could reduce the country’s total greenhouse gas emissions by at least five percent.

In collaboration with Food Recycle Ltd. and Poultry Hub Australia, a team of University of New England researchers led by Postdoctoral Research Fellows, Dr Amy Moss and Dr Thi Hiep Dao, studied the impacts of feeding hens a waste-based diet using discarded food scraps from businesses such as breweries, hospitals, nursing homes, and hospitality venues. Using a patented production process owned by Food Recycle Ltd., the waste was converted to a granular powder that was suitable to be fed to poultry. After rigorous testing, they found egg quality remained high and did not impact the health or welfare of the animals.

Dr Dao said a switch to waste-based chicken feed at a commercial level could have several positive impacts for both the environment and the hip pocket.

“The increasing cost of commodities, such as soybean meal, paired with the increasing demand for low-carbon poultry products, has put immense pressure on the poultry industry to explore alternative feed ingredients,” Dr Dao said.

“Recycling food waste into poultry feed will help farmers to save on feed costs, generate significant improvements in feed efficiency, reduce the environmental impact of poultry production and assist the Australian poultry industry to meet the growing demand for more sustainable and low-carbon poultry production.”

In Australia, about 65 percent of poultry production costs are spent on feed, while it is estimated 7.3 million tonnes of food ends up in landfill each year. Diverting this waste into a cheap and sustainable feed option is expected to lower greenhouse gas emissions created from producing eggs and chicken meat by 76 and 25 percent respectively. Financially, the low cost of commercial waste, paired with the fact that it can be sourced locally, would have the potential to slash feed costs by half.

Because of these benefits, it’s hoped the patented technology used to produce waste-based feed is adopted widely within the next five years.

Chief Executive Officer of Food Recycle Ltd., Norm Boyle, said there are big plans on the horizon.

“Food Recycle Ltd. has appointed OzHarvest Ventures as the Australian and New Zealand Technology Licensee to exploit the patented and patent-pending technology, and they are currently raising $20 million in capital to build the first production facility for Australia to be located in Sydney.”

“Meanwhile, Food Recycle International Ltd. is working in more than 20 countries to introduce the technology globally. We anticipate that within five years, recycled food waste feed will be the go-to solution globally for the poultry, pig and aquaculture industries.”
