Do you believe insect-based protein is a reliable alternative to traditional soy or fish meal?

Innovafeed and Protix have released a joint paper documenting how industrial integration in insect farming reduces carbon intensity. This development suggests a shift toward more sustainable protein sources as global demand for alternative feeds increases.

Why it matters

Reducing the environmental impact of protein production is critical as marine stocks face sustainability challenges, with only 62 percent of stocks deemed sustainable in 2021. Scaling insect protein offers a potential solution to mitigate the carbon footprint associated with traditional livestock and aquaculture feed.

A joint paper citing Global Feed LCA Institute data shows insect protein production carbon values vary from 0.5 to 77 kilograms of CO2 equivalent per kilogram of protein. Innovafeed reduced its protein carbon intensity fivefold since 2022 to reach 1.2 kilograms in 2025.

The players

Innovafeed

A biotechnology company focused on producing insect-based protein for animal feed and fertilizer through industrial scaling.

Protix

An insect-based ingredient producer that utilizes commercial operations to scale sustainable protein sources for the feed industry.

The details

The industry improves sustainability by co-locating production facilities with partners to recover waste heat and feeding larvae on wet organic by-products. This industrial integration avoids the need for energy-intensive drying processes, which can reduce the carbon footprint of insect meal by up to 80 percent. By transitioning from pilot projects to large-scale, optimized industrial processes, companies aim to lower carbon output further.

2019: Commercial operations life cycle assessment completed for Protix.
2020: Industrial integration found to reduce carbon footprint by 80 percent.
2021: Sustainable marine stocks level fell to 62 percent.
2025: Innovafeed reached 1.2 kilograms of carbon dioxide per kilogram of protein.
2030: Target date for Innovafeed to reach 0.6 kilograms of carbon dioxide per kilogram of protein.

Health Landscape

The push for lower-carbon protein sources follows increased reliance on the Global Feed LCA Institute to standardize environmental impact reporting across the feed industry. This effort marks a departure from traditional reliance on marine-based proteins, which have faced significant sustainability pressure.

While these developments occur in industrial agricultural sectors, they signify a broader push for more sustainable food systems that may eventually influence retail standards for animal products. Consumers interested in environmental health can keep track of how production metrics evolve when selecting protein sources.

The takeaway

Industrial insect farming is evolving to significantly reduce carbon output by utilizing waste by-products and heat recovery. Monitoring the shift toward these sustainable feed sources can help you stay informed about the environmental footprint of the global food supply.
