Alternative Proteins Magazine NEWS 8 October 2025 Goterra announced the successful completion of its first large-scale rendering trial, marking a significant milestone in the commercialisation of insect protein in Australia. Conducted using larvae aggregated from all operational sites and processed with an external regional NSW rendering partner, Goterra explained that the trial produced insect meal containing >70% protein and ~12% fat, exceeding industry requirements, outperforming conventional benchmarks like soymeal and more in line with premium fish meals. “This trial validates a core part of our thesis,” said Olympia Yarger, CEO of Goterra. “Aggregated food waste inputs don’t compromise protein quality. It's a key step forward in demonstrating the consistency and scalability of our product.” This successful trial also marks a deliberate and strategic step in Goterra’s evolution by externalising the rendering process and focusing on core competencies in organics waste processing technology and protein production, according to the announcement. Outsourcing the rendering of BSF meal, oil, and tallow creates better pathways to scale more efficiently and deliver on the current infrastructure gap for food waste processing in Australia. The trial follows the announcement of a landmark partnership between Goterra and Skretting Australia in 2024 to integrate insect protein meal into aquaculture feed. As global demand for sustainable, traceable feedstocks increases, partnerships like this are critical to accelerating Australia’s circular economy.

Working with bio conversion hub producer Inspro, the researchers from Kent’s School of Natural Sciences have tested a novel bio-conversion unit (BCU) based at Bank Farm in Aldington to assess its viability for extensive BSFL production at an industrial scale. This provides real-world analysis of how BSFL could be used to provide an eco-friendly approach to animal feed. BSFL are recognised as a sustainable feed additive for livestock and can help create a more complete system for farms by recycling food waste into eco-friendly protein and fertiliser. The BCU’s effectiveness in converting organic byproducts into valuable biomass through the production of BSFL was assessed to reduce the farm’s reliance on environmentally taxing feed sources, such as soy and fishmeal. The researchers analysed the gut microbiome of the larvae to understand how it behaves when reared on different waste diets at a large scale. They found that larvae reared on low-bioburden substrate (waste with very few germs) in the BCU demonstrated comparable or improved protein and fat content compared to those reared on animal feed.
