Carbon Reduction and Sustainable Food Production in One Step

Deep Branch is a carbon dioxide recycling company that uses microorganisms to convert clean carbon dioxide into high-quality products to enable global sustainable animal nutrition. Founded in 2018, the company is a fast-growing startup operating in both the UK and the Netherlands. (2)

Sustainability of animal farming and broader concerns regarding reduction of emissions are two of the biggest problems of our time. By 2050 the world’s carbon emissions must be net-zero to avoid environmental catastrophe, yet by this point our planet’s population is predicted to increase by a third. With average consumption of animal products increasing, it’s thought that the output of animal farming will have to double to meet demand.

First Slide V3

Of the total emissions associated with the average person, approximately one quarter comes from diet and the majority of those emissions are associated with animal products. Although at Deep Branch we recognise the best way to reduce dietary carbon intensity is to reduce meat consumption, we’re pragmatic in recognising that not everyone sees it this way. At Deep Branch, we’re tackling this problem through the development of Proton™, our single-cell protein.

Rather than relying on the conventional protein sources of protein, fishmeal and soy, which are often shipped from the Americas, Proton™-based feeds can be produced from locally sourced ingredients with 90% less carbon intensity. 

Proton™ is not just dramatically more sustainable, it’s also cost-competitive, making the transition to Proton™-based feeds an easy decision to make.

Our Founding Story

Deep Branch co-founders met at the University of Nottingham’s Synthetic Biology Research Centre (SBRC). Whilst working together on ways to utilize gas fermentation for the production of chemicals, the team discovered they had a shared desire to make a positive impact on the world. Pete and Bart left the SBRC to pursue new challenges in commercial and academic biotech, whilst Rob remained at to continue the work of his PhD. The team kept in touch and when in the summer of 2018 Bart proposed a new twist on how gas fermentation could be used for clean production of single-cell protein, Pete and Rob were sold. They were able to go from idea to raising pre-seed funding within four months, and haven’t looked back since.
