If you like to drink coffee, or have a coffee shop, coffee shop, and restaurant that also many serve coffee, do not waste coffee pulp. Because the coffee grounds can be used as a new energy source.
Is Bio-bean, a start-up from the UK who managed to create biofuel-based coffee grounds. In cooperation with Shell (RDSB) and Argent Energy, Bio-bean uses this latest fuel to drive a diesel bus in London as a pilot project.
To date, Bio-bean has produced 6,000 liters of coffee oil as a pilot project used by the London transport authorities to drive one of their diesel buses. That much coffee oil is claimed to be enough to help the power setera with one city bus for a year. "This is a great example of what can be done as we begin to rethink waste as an untapped resource," Bio-bean founder Arthur Kay said in a press release.
Bio-bean collects coffee grounds from cafes, restaurants and coffee beverages, then and transports them to its recycling facility. There, the coffee grounds were dried and then extracted into coffee oil. The extraction results are then mixed with other fuels to make B20 biofuels, which can be used in unmodified diesel buses.
"We're spending a hefty coffee powder and containing valuable compounds, and making them the ideal feedstock to produce clean fuels," Bio-bean said on their official website.
In the UK alone, the number of coffee drinkers is very much, so they will have no trouble obtaining raw material of coffee grounds. Bio-bean estimates that the UK produces 500,000 tonnes of coffee grounds a year, mostly dumped in landfills where they can release greenhouse gases that are harmful to the environment.
Although it has succeeded in creating fuel based on coffee grounds, Bio-bean says that there is no "formal agreement" to continue using its coffee oil in London, but they hope to soon find a new market.
"There is great potential for this project to flourish in the United States, the largest number of coffee drinkers on the planet, 400 million cups per day," the company said in a written statement.
In addition to Biodiesel fuels, Bio-beans also process coffee pulp into "Coffee Logs", a kind of briquettes that can be used in a furnace instead of wood or coal briquettes.
As an additional note, Arthur Kay, who founded Bio-bean in 2013, won the BusinessGreen Leader Awards as Enterpreneur of The year 2017 in June 2017. "In one of our most competitive categories, Arthur Kay won this award with the presence of Bio-bean as one of the most exciting start-ups in the UK today.He has pursued a vision to convert waste into sustainable fuel and has developing a successful and increasingly successful business profile that is impressive in the process, "BusinessGreen said in remarks when submitting the award.
What about in Indonesia? As one of the largest coffee-producing countries in the world, and also with the rapid growth of coffee shops, it is unfortunate that until now no one has come up with ideas, or at least mimics Bio-bean steps to make coffee grounds as an environmentally friendly fuel alternative.
