In the quest for sustainable energy sources, scientists and researchers worldwide are continuously exploring innovative ways to harness energy from natural resources. One such groundbreaking development is the extraction of biofuel from tree bark, a method that is revolutionizing the energy sector and changing the landscape of renewable energy. Tree bark, often considered a waste product in the timber industry, is now being recognized for its potential as a valuable resource for biofuel production. The process involves converting the lignin, a complex organic polymer found in the bark, into bio-oil through a method known as pyrolysis. This transformation is an energy-efficient process that results in a renewable energy source, contributing to the reduction of our reliance on fossil fuels. …Research and development in this field are ongoing, with scientists working tirelessly to improve the efficiency and sustainability of the conversion process.
