To a elaborate sustainable waste management program for the city, we need to investigate the existing flow of wastes. But, to complicate the situation, the statistics are often not available and rarely reliable. According to various estimates, every year Saint Petersburg produces from 5 to 9 million cubic meters of MSW [Cherp, Vinichenko, 1998], so the amount of scrap glass is 259-900 thousand cubic meters per year. About 30% of waste by weight and 50% of waste by volume are packaging materials [Minko, Bolotin, Zhernovaya, 1999]. Every year the composition of waste changes and the main tendency is of an increasing variety of wastes. Nowadays in Russia, particularly in Saint Petersburg, homeless people have to adopt to living outside, the main sources of their revenue is dust-heaps. They select paper, aluminium and glass bottles from the generał waste flow and then hand them to point of utility materiał acceptance. Homeless people change the composition of dust heaps to a great extent. So it is impossible to estimate the content of some waste. It is necessary to say they help to solve the MSW problem, but, of course, there are such components, which cannot be used even by them, because of the waste's non-recyclable character. In Saint Petersburg not only homeless people select waste, but some pensioners also do it because of a lack of money. (fragment of text)
