Well now food waste climate tech startup Goterra will be feeding the real thing to fish for real as part of a new partnership with Tasmania-based aquaculture feed supplier Skretting Australia.

Founded in 2016 in Canberra Goterra recycles food waste using modular maggot-based robotic systems. The black soldier fly larvae eat through the waste, converting it into high-value, low-impact protein and fertiliser in just 12 days. The maggots are turned into livestock feed – and now fish feed. 

The solution diverts waste from landfills and slashes carbon emissions to deliver a 97% reduction in CO2e. Goterra now operates across six locations spanning four states, bringing its green technology to companies including national retail giant Woolworths. 

CEO and founder Olympia Yarger said the partnership with Skretting Australia will drive the upscaling of technologies  to mitigate food waste impacts, while contributing to the sustainable production of Australian farmed seafood.

“Collaborating with our offtake customers like Skretting, contributes towards their ambitious ESG targets whilst also closing the loop of this circular value chain,” she said.

“These are the partnerships that stabilise the foundation of a circular economy. Global business with regional inputs ensure stability of production, sustainability of inputs and ensure that Australian Agriculture continues to deliver high quality produce with feed produced right here in Australia. I could not be more proud to embark on this next stage of our journey”.

Skretting Australia, the Australian arm of Nutreco’s aquaculture division. Among the concerns around Tasmania’s salmon farming industry is the demand for fish as feed, with demand beginning to outstrip supply. The pellets used to feed the industry are typically made from chicken meal and fish meal. The validation of insect meal offers a new, more sustainable option.

Skretting Australia marketing manager Rhys Hauler said Goterra’s insect meals has great potential to be used as a source of protein in their aquafeeds.

“We are constantly looking for new low-cost, low-footprint ingredients to increase our raw material flexibility,” he said.

“Goterra insect meals offer the potential to deliver on both of these fronts. We see these materials as not only safe and sustainable, but also of a quality that protects the end product, maintaining the nutritional benefits consumers have come to expect from high quality seafood.” 

Goterra raised $10 million in a bridging round last year, having previously raised $8 million in mid-2020, with backing from agtech VC Tenacious Ventures and Grok Ventures, the family fund of Atlassian cofounder Mike Cannon-Brookes.

The company is currently looking to raise a Series B.
