Bio-fuel which derived from bio waste or in other words, plant and animal waste has many benefits to mankind for their greater goodness. Although bio-fuel contains disadvantages, the advantages are greater than them according to the articles I referred. Consequently, bio-fuels of all matter are taken from nature. They have energy of sun stored in trees and animals. After some procedures, people can make use of bio-fuel in many ways.
Firstly, accordingly, firewood is a frequent mode of bio-fuel in Sri Lanka which helps to overcome hardships. Villagers can discover it from their surroundings easily as there are plenty of died parts of trees available. It allows many people to make profits from them. People in remote areas can collect and sell firewood, save their money for fuel that uses for cooking as wood is common in rural areas. Consequently, it improves the living standards of destitute in countryside as they gain extra amount.
Thirdly, people can produce bio gas, which is one of the most common forms of bio-fuels, at their home premises at an inexpensive rate. Villagers can easily install a bio gas unit at home. It reduces electricity and cooking costs. Also it diminishes transportation costs. Furthermore, bio-gas units help to make earnings from garbage that throw away from house and garden. As its setup cost and ingredient are cheap, people in rural areas can get a good net profit to enhance their living standard.
These kinds of bio-fuels have drawbacks. The government has to spend a huge amount of money to develop the technology to achieve large amount of profit. Farmers should be encouraged to cultivate oil bearing seeds though they don’t wish to give up their traditional cultivations. As there are not enough oil seeds currently in Sri Lanka, the government and relevant authorities have to wait till those trees produce their crops.
