Calysseo, a joint venture between worldwide animal nutrition leader Adisseo and protein innovator Calysta, is building the first facility in Chongqing, China, which is expected to become the world’s first commercial-scale production facility of single-cell protein.
Delegates gathered at the site for a ceremony to mark the beginning of construction, which will deliver 20,000 tonnes of FeedKind protein in its first phase. A second phase will bring extra tonnes of capacity to the market to meet market demand. The plant will supply the Asian aquafeed market, which represents more than 70 per cent of the world’s aquafeed market.
The plant is being built by Calysseo in the Changshou National Economic and Technological Development Area, Chongqing City. The strategic partnership between Adisseo and Calysta will directly address one of the most important opportunities in aquaculture – to provide high-quality seafood without adding extra pressure to the environment.
The global aquaculture market is experiencing strong growth and is expected to become the third-largest animal protein source, with the production representing more than 100 million tonnes.
FeedKind is produced by fermenting natural gas with naturally occurring bacteria, producing a non-GMO feed ingredient, a safe, nutritious, traceable and affordable protein. The alternative protein will also help to reduce pressure on wild fisheries. If used instead of fishmeal, 100,000 tonnes of FeedKind could mean that between approx. 420-450k tonnes of wild-caught fish could be saved. Used instead of soy, the same quantity of FeedKind could free up as much as 535 km2 of land and would save 9 billion liters of water.
