bio-bean is getting the world #poweredbycoffee

by TTT in


We recycle waste coffee grounds from your morning cup of coffee into local, sustainable biofuels to power your city. Now, our new product - Coffee Logs -  help you heat your stove in winter and your BBQ in summer.


About Us

bio-bean is an award-winning, UK-based, clean technology company, the first in the world to industrialise the process of recycling waste coffee grounds into advanced biofuels, displacing conventional fuels and chemicals in the process.

A few years ago, architecture student, Arthur Kay, was designing a coffee shop, when he came up with a crazy idea - what if coffee waste could be used to power our cities, buildings and even our cars? Where others saw waste, he saw an opportunity and set about turning this vision into a reality. Arthur founded bio-bean, which now owns and operates the world’s first coffee waste recycling factory with capacity to process 50,000 tonnes of waste coffee grounds a year (this accounts for one in ten cups of coffee drunk in the UK!). The bio-bean team is made up of 25 passionate biochemical engineers, mad scientists and eco-warriors and is in partnership with pioneering R&D, green energy and waste management companies.


We have already recycled the waste from millions of cups of coffee and we are giving you the exclusive opportunity to power your BBQ or your stove with Coffee Logs, helping us on our journey to get everyone #poweredbycoffee!




How Do We Do It?

We know this all sounds a bit wacky, so we want to tell you how we do it:

  1. bio-bean collects waste coffee grounds from instant coffee factories, coffee shops, office blocks and transport hubs all over the UK.
  2. At our factory in Cambridgeshire, the waste coffee grounds go through a variety of complex processes to turn them into useful and highly calorific advanced biofuels.
  3. We supply these biofuels back to producers of the waste coffee grounds, creating a truly circular economy. Our Coffee Logs, however, are designed for you to use in your stove or BBQ, our first product for the general public.



What Are Coffee Logs?

Every year we burn millions of tonnes of imported, expensive and dirty wood and coal.

We thought there has to be a better solution and so, in response to this, we have developed a new product - Coffee Logs - biomass briquettes made from waste coffee grounds. They are a clean, cheap, local, sustainable (and fun!) alternative to dirty imported fuels. They are the perfect fuel for heating your home in winter or your BBQ this summer. This campaign gives you the exclusive, first chance to be part of this innovative product launch.

Designed, developed and manufactured by bio-bean in the UK, our Coffee Logs can be used in a wide range of different appliances such as wood burning stoves, chimeneas, BBQs, pizza ovens, smokers or just on an open fire. When compared to conventional woody fuels, Coffee Logs:

  1. burn hotter and longer;
  2. ignite quickly;
  3. are more sustainable;
  4. are more cost-effective; and
  5. are manufactured by bio-bean in the UK from locally sourced waste coffee grounds.

Launching and distributing Coffee Logs at scale is expensive and we need your help to do this. Examples of a few costs we need to cover include expanding the existing factory, hiring a few more clever engineers, packaging, transport and finally delivery to you, our customers.
