Analysis of the economic viability and environmental impacts of a conceptual process model for the recovery of lactic acid from spent media in cultivated meat production

Biotechnology Progress, EarlyView.
Abstract Scaled production of cultivated meat (CM) will co‐produce large volumes of spent media. Recycling of abundant metabolites such as lactic acid in spent media offers an opportunity for valorization and reduction of the carbon footprint of CM production; however, the feasibility has yet to be examined.
