VFAs such as acetate, butyrate and propionate are chemical building blocks used in a wide range of products, including cosmetics, food additives, pharmaceuticals and plastics. Their production often involves carbon-intensive processing of petrochemical feedstocks, but a more energy-efficient alternative has recently emerged A collaboration between chemical engineers and animal scientists has created a system for recovering valuable industrial chemicals from animal waste, representing a major step towards circularity and environmental sustainability.The incorporation of selective ion-exchange membranes into an electrochemical separation system, the system is 80% more energy efficient than previous standard electrochemical processes. The main barrier to its widespread implementation is the lack of an efficient method for extracting VFAs from the chemically complex broths that result. O you think that the system will help lower the cost of production ?
