Greenhouse gas hunter
As with many organic wastes, self-dissolving beans also generate methane gas. Methane is a gas that heats the sphere 86 times more than carbon dioxide. In this case, it is terrible that almost all of the grounds are thrown away.
When the waste is handled correctly, they can even support the fight against climate change by trapping greenhouse gases. According to a study, heating beans with potassium hydroxide creates a material that traps methane. It is also stated that this material can trap carbon like methane and is faster and more economical than other carbon capture and storage methods.
When it is recycled, it can be used in many areas, from bio-fuels to fertilizers, which do not harm the environment. Because it contains rich natural oils. 1 lt of biodiesel fuel can be produced from 5-7 g of its grounds.
Since 2013, a recycling factory called Beo-Bean has been operating in England. It produces an alternative fuel to fossil fuels (logs and pellets) and it is stated that this fuel emits 80 per cent fewer emissions to nature.
Alternatively, bio-fuel production will be made at the Bio-Bean factory. It is stated that it has produced 2.5 million cups and 6,000 litres of fuel so far, and this amount will be enough for a bus for a year.
