Waste
In our daily activities, we produce a lot of waste. When we unwrap a packaged snack, or leave some broccoli in our plate, or if we decide it is time for a new videogame, we are saying that we no longer want to use those things and therefore we want to get rid of them. It is a very simple gesture, once decided, we throw everything in the trash and when it is full, we throw the bag full of rubbish in the large bin outdoors. From this moment onwards, there are special services in charge of managing our waste and the problem is solved for us. Actually behind waste there is a lot to know and a lot that we can do. First of all, what is waste?
