Plastic waste into fuel

Scientists at the University of Pennsylvania discovered that plastic waste can be transformed into small pieces of plastic used as fuel. Under normal circumstances, all kinds of plastic waste, including dirt, must be buried. However, in the method developed by the University of Pennsylvania, this small piece can be mixed with coal as a co-fuel for stoves and boilers, or Burning in a cement furnace.
The shredded plastic is fed into an electrically heated mold at an appropriate temperature to intensify the heat, melt and fuse the outer layer of the material, and the rest of the material does not melt, and the resulting compressed plastic is snowed into small pieces. It has been calculated that these plastic pieces provide 20 times more energy than they need to produce them. Even if these plastics can be re-melted and reshaped, the traditional recycling process also requires a relatively high energy input. Currently, the University of Pennsylvania is conducting combustion experiments on these small blocks to calculate the amount of heat they emit. Researchers claim that they do not plan to use polyvinyl chloride because of their presence of contaminated emissions.
