Recycling





Everyday, all around the world, people consume a lot of products and do a lot of trash. This trash could be recycled or not. The best thing to do is to recycle. In America, after having collected the trash, it is separated by types -paper, plastic, glass, metal and comom trash. The trash that could be recycled go to a special machine that "pack" it and then it is transported to other places where it is recycled. The trash that can't be recycled goes to a landfill where it is squashed, to remove the air and make the trash good to build on (because there are some explosive gases that obviously are dangerous), and covered with earth. A landfill can originate fields for other purpuses, so landfills can be reused after having all the trash. The trash produces methane gas that is harvested by wells, feeds a gas turbine and produces electricity and that gas can be used to fuel, for example, the garbage trucks too. So trash have a cicle, it produces fuel to fuel garbage trucks so that they can collect more and more trash.

So, with this we can see that recycle and reuse waste for other purpuses is possible and better to the environment. If America does this why doesn't other countries do it too? Think about it: after "packaging" the garbage it is worth a lot of money so it could also solve some economic problems and the world will be better if everybody recycle and every country helps people to do it. Imagine a world without trash spread in the nature and green places where the electricity of our homes is produced from trash gases and where the fuel of our cars is "produced from trash". Imagine a total green world where it is better go out than staying at home watching TV.
