Biofuel Using Waste Coffee Grounds – Brewing
Another major contribution from the clean technology company, bio-bean, awaits the world. The organisation has been instrumental in reducing greenhouse emissions by reducing the dependency on conventional fossil fuels. It does so- by- recycling waste coffee grounds into advanced biofuels and biochemicals.
If you are wondering how coffee waste can contribute both environmentally and economically, then let us give you some hard facts first. Coffee is a preferred drink and a fantastic one too, but as much as it works for the world over a cup of coffee, its waste is enormous. Facts show that – each espresso-based coffee creates about 25 grams of waste coffee grounds.
So, What Is the New Economics?
The company bio-bean has now partnered with Shell engine oils and lubricants. It is a big collaboration especially in the context of linking waste coffee grounds with saving the business money.
A media report confirms the breakthrough collaboration indicating that London Buses will be powered by coffee way of fuel. Shell and bio-bean will work together to produce a new B20 biofuel. The same fuel produce will be used to power London Buses. There is no need to do any modifications to the fleet of London Buses which is an outward win-to-win situation, saving costs and contributing to the environment.
The news comes as a big relief to the London city problems of severe air pollution.
Why the Big Deal?
The coffee logs (a consumer product which is a proprietary) of bio-bean is a tried, tested and proven fuel of choice. It is currently in use in different households proving them with a long-form, clean, sustainable way of heating their homes. Coffee Logs are briquettes used in stoves, chimneys and fires.
It only becomes large-scale from here. The power of Shell and bio-bean will scale-up the waste coffee plantation, creating thousands of litres of B20 biodiesel with a noble purpose. It will for the first-time ever power London Buses.
It is a big breakthrough laying focus on the untapped potential of a renewable source like the biofuel.
How Will It Work?
The coffee at stale is huge. The average Londoner has about 2.3 cups of the beverage in a day, which went converted to a now useful waste, amounts to a whopping 200,000 tons in a year.
The Shell-bio-bean team skilfully replaces the 126 million kg of CO2.
The plan is to include coffee waste content from high street chains as well as factories.
Behind the Scenes
The company has a waste coffee recycling factory at Alconbury Weald and has an officially designated fuel partner Argent Energy.
Recently, in November 2017, Shell, bio-bean and fuel blender Argent Energy titled the new biodiesel initiative as a #makethefuture program. The fuel to be made is- a B20 blend.
It is prepared by first blending Coffee Oil with other fats and oil. The coffee oil is extracted from waste coffee grounds. The blended oil is then made into biodiesel by Argent Technology. Followed by mixing it with mineral diesel. Till date, about 6,000 litres of coffee oil has been produced under this project and it is enough to run a London Bus continuously for one year.
It is a very promising initiative for the future transport services since B20 biodiesel gives a CO2 emission reduction compared with conventional mineral diesel.
It provides a big relief from the harmful methane produced at landfill sites where coffee waste is sent to decompose. Methane is a greenhouse gas which is 20 times more harmful than CO2 in a global warming effect.
Arthur Kay set up bio-bean in 2013, making it the first company ever to industrialize the recycling of coffee waste into something useful- the advanced biofuels and biochemicals.
It was a win-win situation given the vast statistic of UK coffee waste generation of 500,000 tonnes every year. The landfill sites most of the coffee waste is dumped emits methane which has a greenhouse effect more powerful than the CO2. So, instead of letting the methane emission damage the environment and also to save the cost of using landfill sites in the UK (subject to the landfill tax), Arthur thought of doing the unique. He established bio-bean with a personal conviction that there is nothing waste and that effective utilisation of resources will negate this presumption of coffee waste. Eventually, the highly valuable compounds of waste coffee grounds were put to produce clean fuels, beginning with Coffee Logs.
Today, the organisation works to create a better waste infrastructure using spent coffee grounds such as from cafes, offices, coffee factories and transport hubs, only to create a sustainable and dependable environment.
