Recycle

To understand RECYCLING IS IMPORTANT "recycle" the CONCEPT THAT HAVE GARBAGE and stop seeing IT AS SOMETHING DIRTY AND USELESS IN ITS ENTIRETY.
Recycling is an industrial process that converts the waste discarded (secondary raw material) into a product similar to the original or another. Recycle to save energy, save natural resources and bring back to the production cycle that is thrown away. The word recycling was introduced to the international vocabulary in the late 80s, when it was found that the sources of oil and other raw materials were not renewable and are running out. Recycling means = Re (repeat) + Cycle (cycle).
To understand recycling, it is important to "recycle" the concept that we have garbage and stop seeing it as something dirty and useless in its entirety. The first step is to realize that waste is a source of wealth and that to be recycled should be separated. He can be separated in several ways, the simplest being to separate the organic waste from inorganic waste (wet / dry waste).

 
In nature nothing is lost. Decomposers living beings called "eating" lifeless material or decomposition. They divide the field so it can be recycled and used again. This is called the biodegradable material. When an animal dies, it is recycled by nature. When a material is broken into small pieces, bacteria and fungi, the most important decomposers, they can work.
The aerobic decomposition is more complete than the anaerobic for generating carbon dioxide, water vapor and mineral salts, substances essential to the growth of all plants, which generate the humus, great fertilizer for the soil.
Anaerobic process, are generated gases (methane and hydrogen sulfide), which cause an unpleasant odor, the anaerobic decomposition produces a dark liquid called leachate (liquid with large amounts of pollutants) normally found at the bottom of the trash cans. This slurry is the main cause of the contamination of rivers and groundwater.
Recycling brings the following benefits: Contributes to reducing the pollution of soil, water and air. Improve the cleanliness of the city and the quality of life. Extends the life of landfills. Improves the production of organic compounds. Creates jobs for the unskilled population. Generates revenue by selling the recyclable material. Stimulates competition, since the products generated from recycled are sold alongside those produced from virgin materials. Contributes to the enhancement of public sanitation and to form an ecological conscience.
In Brazil, it is important that small and medium-sized recycling companies have financial and technological support to improve their recycling technologies, as this would be contributing in generating jobs, reducing waste and producing better quality products in clean technology .
A great solution for solid waste is one that provides the maximum reduction in the amount of waste at source. When waste can not be prevented should be recycled for reuse or recovery, so that is the minimum possible what is intended for final disposal by landfill.
The recycling has emerged as a way of reintroducing a system of the matter (and energy), which would become trash. Once diverted, waste is collected, sorted and processed for use as feedstock in the manufacture of goods which were previously made with virgin raw material. Thus, natural resources are less committed.
