Dealing with waste plastic



Every year people throw away millions of tones of plastic.
Plastic is made of petrol and this pollutes a lot. Furthermore, this creates huge mountains of waste that will never disappear.
Some years ago, scientists discovered how to reduce this problem by turning old plastic waste to new. It consists in a mechanism which melts every kind of plastic, and then they cool it producing a waxy substance that can be used to make new plastic items.
I’d to conclude by saying that we all could put our grain of sand by reusing plastic bottles and also by doing our shopping using “shopping baskets”, these ones that used to use our ancients.
