NovoNutrients, a US-based startup led by David Tze, has developed a method to convert CO2 into protein for both human and pet consumption. The company has raised $18 million in a Series A funding round to build a pilot-scale facility to demonstrate the scalability of its fermentation process, which tweaks bugs to achieve this conversion. This innovative approach, reported by TechCrunch, aims to reduce carbon emissions and provide a sustainable protein source. Similarly, another startup, Savor, has created a synthetic vegan fat from CO2, which could cut carbon emissions and save rainforests by eliminating the need for livestock and farmland. These advancements highlight the growing trend of using biotechnology to create sustainable food sources.
