Review of MSW recycling technologies in Russia and abroad
All known technologies of waste recycling and processing have been entered the Russian market by 2010. Foreign experience shows that a rational organization of MSW processing offers a chance to use up to 90% of recycled polymers in the construction industry, for example as concrete aggregates. The incineration of 1,000 kg of MSWs yields energy equivalent to that produced by burning 250 kg of fuel oil. The real savings turn out to be even greater, since waste, unlike fuel oil, requires no expenses for its production.
When developing a thermal recycling technology, it is important to control atmospheric emissions of nitrogen dioxide and furans. Based on profitability and environmental friendliness, the following municipal solid wastes storage and recycling methods can be cited as promising: preliminary sorting, landfilling, incineration, biothermal composting, low-temperature and high-temperature pyrolysis.
