Alternative Proteins Magazine NEWS 14 October 2025 A recent study conducted by Better Insect Solutions in collaboration with FarmInsect sheds light on the carbon and water footprints of BSF farming. The study analyzed three operational BSF farms each producing between 400 and 1,000 tons of live larvae annually. The study focused on the "fattening stage" of BSF larvae, where young individuals are grown into harvest-ready larvae – similar to broiler chicken production. All three farms reported emissions below 1 ton of CO₂ equivalent per ton of fresh BSF larvae produced, the study found. In fact, when benchmarked against broiler farming, BSF production showed up to 40% lower emissions. This is considered a game-changer for the feed industry, which is under increasing pressure to reduce its environmental impact as well as remaining cost-effective. In the study, feed for the larvae emerged as the most significant contributor to emissions, but also the area with the greatest potential for improvement. Farms using organic waste streams like potato pulp dramatically reduced their carbon and water footprints. According to the GHG protocol, true waste materials carry zero upstream carbon burden, making them ideal for sustainable feed.

Following the launch of the world’s first dry dog food based on microbial protein in early 2025, the Swisttal, Germany-based company is now presenting a complete range for future-oriented canine nutrition, including the world’s first vegan wet dog food with microbial protein. With the new MicroBell wet food and MicroBell snacks, Marsapet is reportedly offering dog owners for the first time a fully vegan product line consistently based on microbial proteins. Both products embody innovation, sustainability, and a forward-looking approach to canine nutrition – from daily meals to healthy treats in between. “Tierisch gut, ganz ohne Tier!” (“All the goodness, none of the animals!”) – Marsapet states that this claim is now brought to life in three product categories. MicroBell Snacks impress with their innovative recipe and delight dogs, while the wet food stands out with its creamy texture, offering a modern and complete form of vegan canine nutrition. “With the expansion of our MicroBell line, we are creating an entirely new category in pet nutrition,” explains Marcel Hoffmann, Managing Director of Marsapet GmbH. “Dog owners can now feed their companions in a fully sustainable and wholesome way – without compromising on taste or nutritional quality. This is true innovation that makes a real difference.” Read more>> Marsapet unveils vegan wet dog food Photo: Freepik
