This UK business turns coffee into fuel

Starbucks (the coffee) started trying recycled alternatives disposable cups. However, the coffee used is often overlooked. Bio-bean in the UK believes it has found a way to turn this waste into a valuable resource.
The world is drinking around 2 billion cups Coffee producing 6 million tons of used ground every day 2011 study. When they go to landfill, rotting areas release greenhouse gases into the atmosphere, contributing to global warming.
However, bio-bean 7.000 tons It is based on biofuels for a year. In 2017, it developed a coffee-based biofuel for use in it. Diesel buses in Londonbut wasn’t commercially viable, so the company shifted its focus to solid fuels for home and industrial use.

Bio-bean, $ 7 million It has been providing funds since it was founded in 2013. Costa coffeeLondon Rail Station and UK rail operator Network Rail.

“We succeeded to be really successful with our innovations [because] we managed to scale, “says Bio-bean Director and Commercial General Manager George May.” Other people can recycle one or 10 tons of coffee. We have realized more than 20,000 tons of recycling in our lives. ”

Bio-bean has been affected by the Covid-19 crisis, but its activities continue. While coffee outlets in the UK have been temporarily closed due to coronavirus restrictions, Bio-bean said it can still pick up soil from various recycling partners, but in lower volumes than usual.

Coffee as fuel

At the company’s Cambridgeshire facility, the used coffee grounds are decontaminated to remove paper cups or plastic bags, and then through a dryer and further screening. Finally, they are processed into products such as biomass pellets and home fire logs.

The company also produces a natural flavor extract in a separate process from ground coffee particles.

Pellets can be used to power industrial boilers, heat commercial greenhouses or dry cereal products, while coffee logs can be used on wood stoves.

“Coffee is extremely calorific and makes itself a really cool fuel,” says May. “They burn about 20% warmer and 20% longer than wooden logs.”

The founder of the company costs one pound of Bio-bean coffee logs £ 7 ($ 8.70) - similar to other fire logs found in the UK.

Jenny Jones, a professor of sustainable energy at the University of Leeds, says recycled coffee grounds have potential as fuel, but must be compared to alternatives to deal with coffee-ground waste such as incineration and assessment of total carbon savings. or mulching for plants.

Jones also says that ground coffee particles, like most biomass residues, are higher in sulfur and nitrogen than most wood emitting harmful gases such as sulfur dioxide and nitrogen oxides when burned.

Despite being postponed by the coronavirus pandemic, Bio-bean said it plans to expand its operation to northwest Europe in the next five years.
