Biofuels and health hazards: An overview

Biofuels, such as coal and oil, have been the most suitable and sufficient substitutes for other conventional fuels in the energy sector for the last few years. For decades, entire populations have suffered from deforestation, global warming, and carbon monoxide issues. Biofuel production is an eco-friendly process that still has health hazards for manufacturing unit workers. That is due to flammable and combustible raw materials and their chemical reactions. Bioethanol is a flammable biofuel prepared by cellulose items and the fermentation of grains. Biodiesel is another combustible liquid-based biofuel produced by alcohol and glyceride in vegetable oil duly catalyzed by strong alkaline like caustic soda. Biofuel plants or trees are the biggest isoprene producers, which meet the ozone layer in the earth's atmosphere. While combining with ozone always causes many health hazards for manufacturing units' employees despite several safety measures. One of the significant consequences is that some factory workers often have asthma, allergy, and lung disorders due to ozone attacks.
