Energy has needs in every sector all over the world, such as transportation, industrial development, home heating, and electricity production and in our daily life. Till now most of the energy production depends on the crude oil sources but in our planet the crude oil sources are limited. There is a probability that once these energy sources may come to an end, it could cause disastrous collapse of the human civilization considering the future fade of this universe scientist and researchers all over the world had been doing research for new alternate energy sources like solar energy, wind energy, bio-fuel etc. Plastics are produced mainly from crude oil. Incomprehensible amount of plastic bags are consumed every year all over the world and after use the discarded plastics bags become a severe problems to the natural environment. Dumping of these waste plastics create hazardous land fill problems, to avoid this problem transport of plastic waste to landfill cost $2800/ton. A new simple and cost effective technology has been developed for the conversion of the waste plastics into low sulfur diesel fuel. This developed technology can convert most types of waste plastic into low sulfur diesel fuel.展开更多
