Waste recycling, as they say, no money nor fame. If it were not for migrant workers ... September 2008 the Leningrad region. Waste recycling. Had never met with this problem. Know that there are huge dumps around the cities that spoil the environment and are free magazine for the homeless. I've heard that somewhere there are plants for waste processing and even generate revenue.
But in fact it is very difficult, not only for us, but even in wealthy countries. Unprofitability, toxicity, failure to complete the sort unpredictable components and so on. And the fact that it is difficult (except weapons and space programs), we do know, is very bad. And who will go to work with garbage somewhere outside the city limits for low wages.
