bio-bean was founded in 2013 on the firm belief that there is no such thing as waste, only resources in the wrong place.  We set out to extract the latent energy in spent coffee grounds and convert it into biofuels and biochemicals in a sustainable and commercially-viable way. Five years on we are recycling thousands of tonnes of spent coffee grounds per year to produce our retail product Coffee Logs, a briquette for wood-burning stoves sold through major supermarkets and garden centres, pellets for industrial biomass use and we are also exploring a range of other viable biochemical products derived from spent coffee grounds.

bio-bean is a small, dynamic, award-winning business with offices and factory in Alconbury, Cambridgeshire, a research lab in Welwyn Garden City and a small office in Aldgate, London. We are passionate about our vision, values and people; we aim to be sustainable in everything we do whilst giving our people the space to grow and develop in a fast-moving and high-growth environment.
