Deep Branch

Deep Branch is a carbon dioxide recycling company that uses microorganisms to convert clean CO2 into high-quality products to enable global sustainable animal nutrition.

Deep Branch uses microbes to convert carbon dioxide from industrial emissions into products such as animal feed.

Deep Branch was founded in 2018 by Peter Rowe, Rob Mansfield, and Bart Pander. The company is headquartered in Nottingham, Nottinghamshire, United Kingdom.


Deep Branch addresses both the sustainability of animal farming and the reduction of carbon dioxide emissions with their CO2-to-protein technology, creating the first scalable path for a truly sustainable protein generation process from a waste product.


Deep Branch's first product Proton™, is not just a more environmentally friendly feed ingredient, but will also provide a regular supply of a price-stable, price-competitive, and nutritionally optimal bulk protein.


Deep Branch's platform will roll out multiple Proton production facilities, with an anticipated 600,000 tonnes per annum global capacity by 2030, utilising over one million tonnes of carbon dioxide every year.


Deep Branch is backed by Novo Holdings, UK government’s BEIS, DSM Venturing, Total Carbon Neutrality Ventures, Barclays Sustainable Impact Capital and others. The company received £4.8M in new financing on Jun 07, 2022. This brings Deep Branch's total funding to £15.3M to date.
