Europe is most concernec about Sustainability so they pay realy good money for Recycling.
It makes it the easiest way to earn money if you collect tins and plastic bottles and submit in the Recycling centers in any super market.

I came this idea when I met a man in a train with a big bag of recycled cans that he collected from parties and clubs, he told that on weekends he makes up to 150 euro per day and 100 euro on a normal day.
