Our current world can rely on biofuels as sources of green energy. The abundance of lignocellulosic waste in our environment presents a unique potential to meet energy needs by creating biofuels. Due to its high combustible resin content, pine needles are another LB that is entirely a waste product and a cause of soil infertility as well as forest fires. Each pre-treatment method for the generation of biofuels has benefits and drawbacks, however pre -treatment by organic acids has certain advantages like low cost, less corrosive and environmentally benign. The results show that pine needles are a good and prospective source for the synthesis of bioethanol
