Meet The Future Bus That Will Run On Coffee; Future Sustainable Energy From Coffee

Biobean, an energy firm in London is set to release a bus in the capital that will run on fuel made from coffee waste. Arthur Kay, the green entrepreneur behind the firm, emphasized the need for bio-fuel in the modern world of energy diversity, in the spirit of realizing a sustainable environment.

Given that London is one of the most populated cities in the world, the need for cleaner air could never be more crucial. Biobean is actively gathering coffee waste from coffee chains and converting it to liquid fuel and so far, the startup has achieved some visible progress. According to Mr. Kay, diversification is important and as long as people keep drinking coffee, there will always be coffee waste. This obviously means that the firm has unlimited ingredients to keep doing what they are already doing and perhaps expand into other energy related fields.

So how exactly do we go from coffee to fuel? Of course, the technical details of the fuel extraction from a pile of coffee waste is patented, but the basic idea revolves around something called ‘hexane extraction’, which involves evaporation of the coffee grounds to extract the oil. For every pile of coffee grounds, about 20% of oil extracted and the remaining waste can be burnt off as wood fuel.

Bio-fuel first came into play in the early 1990s when it was created from ethanol extracted from Brazilian sugarcane. Issues concerning sustainability of the project later arose and the country decided to shift to bio-gas. Gustaf Landahl in Stockholm is currently pioneering one of the greatest energy projects today, the Smart Cities project, that attempts to explore newer ways to generate energy from food waste. Of course, this would mean cleaner air in our cities, which is quite remarkable to say the least.

Back to London, Mr. Kay seems quite optimistic as he aims to amass tonnes of coffee waste and produce enough fuel to power the whole city. The coffee-run bus will be unveiled by the company in just a few weeks and will probably run in parallel with Ford’s newest 20 plug-in hybrid vans in an effort to prove that with technology, it’s still possible to achieve a cleaner and sustainable environment. A proposal that we all once would have thought as stupid is finally going live.
