Climatic change has become a pressing issue and so is depletion of fossil fuels. Burning of fossil fuel is also contributing in emission of the toxic material in the atmosphere. This, in turn, is interfering with the living conditions of the human beings. To overcome such issues, the scientists and researchers are trying to find a mid-way. The main aim is to find a source of energy which will not harm the atmosphere. Apart from that, the fuel should be bio-degradable and economical.
Recently, researchers from several institutions of China have come across a new discovery. They have published a paper in the journal Science Advances. In the paper they have demonstrated the way to produce bio-coal from plant waste. Moreover, the paper also contain the process as well as description of production and uses respectively.
Researchers claim that the use of bio coal will reduce the emission of CO2 in the atmosphere. And this, in turn, will help control global warming. Also, the process of creating a bio coal is way greener than that of the natural coal.
Re-use of Abundant Bio-Waste to Produce Bio- Coal
Scientists have tried converting plant waste into energy source, and bio-oil is one product of such effort. However, bio-fuel as an energy source offers several drawbacks. They are chemically unstable and have fluctuating caloric value. After heating bio-oils at 240 degree Celsius, it will produce black, and hard material. The appearance of the material is similar to that of natural coal. After experiment, the researchers concluded that the coals could be burned just like the natural coal. It can produce enough heat to boil water. Further, it will help produce thermal energy.
The bio coal can be produced using variety of natural ingredients, which come under the category of bio waste products. Some of the ingredients include- straw, rice husks, soybean straw, sawdust and bagasse. Among all, as per researchers, rice husks is the best and are easily available around the world.
The researchers suggest that bio-coal is the best alternative to replace natural coal. Moreover, combustion of the bio coal does not emit cadmium, zinc, manganese or lead in the atmosphere. Also, it can reduce the emission of CO2 in the atmosphere substantially.
