Recycling plays an important role in the reduction of solid waste. In 2010, the European Union recycled 31% of all its waste, and considering a recycling rate of 1% of GDP in the European Union. However, Brazil recycles only 13% of its urban waste, losing 8 billion a year according to the Institute of Applied Economic Research (Ipea).
Unused waste has filled public dumps, which is a serious environmental problem. So to end this problem, the National Solid Waste Policy was created, which establishes principles, objectives, instruments and guidelines for the management of solid waste. The treatment of these wastes has the following order of priority:
- Not Generation
- Treatment of Solid Waste
- Environmentally appropriate final disposal of tailings
Law 12,305 / 2010 obliges companies and municipalities to adapt. However, many municipalities have not been able to close the dumps, which will be replaced by landfills, but they have high costs. To reduce landfill it is essential to reduce the volume, because if the volume of waste that is destined for landfills is landfilled, then it will soon become economically unviable.
To reduce the volume it is necessary to reuse with the compost, where branches, trunks and trees crushed and mixed with other organic waste, produce a fertilizer of excellent quality. Also recycling waste such as cardboard, glass and metals that can go back to the industries and decrease the generation of new waste. With these processes, the volume of waste will decrease dramatically, where it is possible to treat and deposit in landfills.
