The waste produced by each person varies from 502 kg / year (values declared by the EU) for the most industrialized areas such as Europe, the US, etc. down to 304 kg / year for the less industrialized areas.
The quantity produced in the world is estimated at about 4 billion tons a year. Of this about 60% is from the organic fraction and of this about 70% ends up in landfills which are unmonitored or illegal. The percolation of this waste is the main cause of pollution of water and soil.
