A fuel It is a material that, due to its properties, burns easily. The concept usually refers to the substance that, when oxidized when ignited, gives off hot and release Energy that can be taken advantage of.
Fuels, in this way, generate mechanical energy or thermal energy. The gasoline (also known as naphtha), the diesel oil or gasoil, the natural gas, the wood and the Coal they are some of the most widely used fuels worldwide.
All fuels have a certain calorific value: the amount of Energy (heat) released per unit volume or mass when the oxidation reaction occurs. This reaction begins when the fuel reaches its ignition temperature.
The fossil fuels they come from biomass whose origin dates back several million years. The Petroleum, the Coal and the natural gas are examples of this type of fuel, which they are not renewable (once they are exhausted, they disappear, since they cannot be generated at the same rate as their consumption).
It is important to bear in mind that, when oxidation occurs and energy is released, fuels leave different waste. Among them appears the carbon dioxide, a polluting substance that contributes to the greenhouse effect.
Most cars, for example, need gasoline (naphtha) to run. This fuel consists of a combination of hydrocarbons that come from oil. When the gasoline in the combustion chamber of the motor, the chemical energy of the fuel is converted into the mechanical energy that allows the movement of the vehicle.
Bio Bean and coffee as fuel
Since the end of 2017, a young British company called Bio Bean started converting large amounts of coffee grounds waste into biofuel capable of supplying the almost ten thousand buses of the city of London. It is worth mentioning that the London bus network is among the busiest on the planet, which is why the achievement is even more impressive and, why not, beneficial for the economy usually.
Approximately disposed of in the UK every year two hundred thousand tons of ground coffee waste, which after its decomposition in the landfills they generate a considerable emission of methane gas that exceeds almost thirty times the harmfulness of carbon dioxide.
Arthur Day, founder of Bio Bean, relied on the high calorie content of ground coffee to carry out research on its potential as a fuel for both private use and automobiles. industrial. After having received permission from the authorities, the company embarked on the production of six thousand liters of coffee oil.
Bio Bean was supported from the start by many factories and coffee shops across the UK, and this tipped the balance in favor of the project in a decisive way. The coffee oil must be mixed with certain fats to give a biocomponent of 20% to which it must then be added diesel ore to get the biofuel B20.
Without a doubt, 2017 marked a milestone in the history of the fight against environmental pollution, since thanks to this revolutionary fuel, carbon dioxide emissions began to be reduced to significant levels. Two of the companies that collaborated with Bio Bean are Argent Energy and Shell.
Before this endeavor, others had taken place with similar purposes, which were also tested in the almost ten thousand vehicles from the London bus network; for example, fuels made from meat waste and oil. In the words of Arthur Kay, this project “is a good example of what we can achieve when we begin to see waste as unexplored resources.”
