Sir, I concur with your correspondent R. Dean1 on the unprecedented usage of PPE (personal protective equipment) leading to the other PPE (polluting Planet Earth). One good alternative to protect Mother Nature in this situation is the conversion of plastic waste material into a liquid biofuel. Pyrolysis is the procedure of conversion of any material at very high temperatures. All PPEs which at present are disposed in landfills, oceans, etc, which impose negatively on aquatic animals, can be transferred to an incinerator and then pyrolysis can be done to break down the propylene chains to form a liquid. The liquid obtained can be used as a biofuel. We are very much in need of fuel for the operation of various mechanical devices. This biofuel can be further reused thus protecting our planet. Due to the increasing population and their demand for energy consumption, this would serve as a healthy alternative and also preserve our nature.2
