bio-bean is a clean technology company founded in 2013 by Arthur Kay. We give used coffee grounds a second life, working with waste management companies to collect grounds from coffee shops around the UK, and recycling them at our factory in Cambridgeshire. Here we clean and dry the coffee grounds before converting them into solid biofuels: coffee pellets for industrial boilers, and Coffee Logs.

Coffee Logs are our first consumer product. They are eco briquettes for use in stoves and woodburners, burning 20% hotter and longer than wood thanks to coffee’s high energy content. Coffee Logs are packaged 16 to a bag and can be purchased online or in garden centres and farm shops throughout the UK.

We are also conducting R&D into the potential applications of the natural oils found within coffee grounds, such as for the cosmetics and food industries.
