30 Aug 2024 --- Biotech company MicroHarvest is formulating fermentation-based microbial proteins with a lower footprint per kg of product, as the global protein demand is set to increase by nearly 50% by 2050, says Julian Schildknecht, head of brand and growth at MicroHarvest. The Germany-based company’s protein ingredients — which it says emit an estimated 2-3 times less CO2 eq/kg compared to plant-derived solutions — can be used for sustainable alt-meat applications.
