Cultured meat or clean meat refers to meat grown artificially as opposed to meat sourced from livestock by conventional slaughtering. Such meat products are grown in the lab directly from an animal cell. In a first, Singapore has given regulatory allowance for sale of lab-grown meat. The advantage of cultured meat is that it is environmentally friendly. It also addresses health concerns and animal welfare concerns. According to Barclay estimates, the alternative meat market could reach 140 billion USD by 2029.
