last few decades mankind produces household waste on a large scale.The modern city for the year accumulates around 300 kg of waste per person, so recycling of waste - one of the most pressing issues of today.
Removal and disposal of waste is a very specific activity that requires the use of special technology.The processing is necessary not only to monitor the implementation of numerous rules and regulations, but also to use techniques and equipment.Very often, industrial waste contains harmful to human substances - heavy metals, dioxins, fluoride.All of them are very dangerous for human health.Harmful substances with rain water into the soil, the air in large quantities released sulfur dioxide and methane.From trash in landfills comes the risk of spontaneous combustion.In addition, illegal dumps are a breeding ground for insects and rodents.
modern approach to this problem - recycling of household waste and the possibility of their further use.Spending time, energy and money on waste disposal is wasteful.However, modern technology allows not only safe to recycle waste, but also reap the benefits.Recycling waste requires a specific type of processing, the result of which will get the possibility of their re-use.
Waste paper, metal and glass can be directly used again.Building wastes which do not change their properties, may be buried in the ground.Solid waste is mainly used to produce fuel.Received after the waste fuel is equivalent in quality brown coal and peat.Scientists believe that the energy produced by conversion of waste into energy and fuel, will be able to cover the needs of one third of the world's economies.Another kind of using solid waste - is fragmentation and conversion to construction materials.For example, crushed and compacted plastic mixed with asphalt and petroleum resins and used for road construction.Also, shredded plastic is used to produce films, roofing materials and toys.
Disposal of waste that need to undergo intermediate treatment - it is alkaline, acid, waste oils.Some settling agents dewatered and dried.Part of flammable products, such as waste oil and plastics - are burned.In modern waste treatment plants it has been established recycling of household and industrial waste, special technology allow you to sort, crush and identify waste fractions, dangerous for the environment and human health.At the global scale uncontrolled accumulation of household and industrial waste is the threat of changing the balance of oxygen and carbon dioxide in nature, reducing the amount of clean drinking water.They entail soil pollution and degradation of water bodies, climate change.The most important task of the global economy is that the recycling of household waste has passed a series of a series of dangerous technologies.
