You know what it is garbage?
Residue or garbage, is any useless, superfluous considered material, and/or without value, generated for the activity human being, and which needs to be eliminated. It is any material whose proprietor eliminates, he desires to eliminate, or he needs to eliminate.
The term garbage is applied generally for materials in the solid state. Useless or superfluous liquids or considered gases, are, while this, generally calls of residues (liquid or gaseous). However, the terms garbage and residues also can be used to describe respectively fluid and solid.
Organic garbage
Organic substance, animals and vegetables. In them it can be included food remaining portions, leves, seeds, remaining portions of meat and bones, papers, wood, etc.
Exactly in the present time this type of garbage is considered pollutant e, when gathered, the organic garbage many times can become inatrativo, highly mal-cheiroso, in general due to decomposition of these products. But, in case that it does not have a minimum of care with the storage of these residues creates a propitious environment to the development of microorganisms that many times can be agents who can cause illnesses. Organic garbage can be decomposed
The main component of the organic garbage is the human, composed garbage for the residues produced for the human body, such as excrements and piss. The human garbage can highly be dangerous, a time that can shelter and transmit with easiness a great variety of worms, bacteria, fungos and .causing viruses of illnesses. A primary accomplishment of the civilization human being has been the reduction of the transmission of illnesses through the human garbage, thanks to the hygiene and the basic sanitation. The organic garbage can be seletivizado and used as seasoning (from the compostagem) or be used for the production of certain fuels as biogás, that he is rich in methane (from the Anaerobic digestion).

Inorganic Garbage
inorganic garbage it includes material all that does not possess biological origin, or that it was produced through half human beings, as plastic, metals and leagues, glass, etc. Considering the conformation of the nature, the inorgânicos materials are represented by minerals.
The majority of the inorganic garbage possesss a great problem: when played directly in the environment, without previous treatment, delay much time to be decomposed. The plastic for example, is constituted by a complex strong on molecule structure between itself, what it becomes difficult its degradation and posterior digestion for agent decompositores (primarily bacteria). To solve this problem, diverse inorgânicos products are biodegradable.
Highly Toxic Garbage
Nuclear and hospital garbage enters in this question. These products need to receive treatment special, or can cause serious ambient damages and/or to the health of many people. Nuclear garbage must be isolated, while hospital garbage must be incentive.
Domestic Garbage: he is the formed one for the solid residues produced by the residential activities and presents around 60% of organic composition and the remain formed for plastic packings, cans, glasses, papers, etc.

Urban Solid Garbage: it includes the domestic residue as well as the residue produced in public installations (parks, for example), in commercial installations, as well as remaining portions of constructions and demolitions.
Industrial Garbage: it is generated by the industries, and she is generally highly destructive to the environment or the health
Hospital Garbage: it is the classification given to the dangerous products without value and considered produced inside of a hospital, as used syringes, aprons, etc. For being dangerous, being able to contain .causing agents of illnesses, this type of garbage is separate of the produced remain inside of the hospital (food remaining portions, etc), and generally is incinerado. However, certain hospital materials, as aprons that had kept constant contact with electromagnetic rays of high energy as rays X, are categorized of different form (the mentioned apron, for example, are considered nuclear garbage), and receive treatment different.
Nuclear Garbage: composition for highly radioactive products, as remaining portions of nuclear fuel, hospital products that had had contact with radioactivity (aprons, papers, etc), at last, any material that had exposition drawn out to the radioactivity and that possesss some degree of radioactivity. Had to the fact of that such materials to continue to emit radioactivity for long periods of time, them total need to be confined and isolated of the remaining portion of the world.
Recycling
The recycling is the process of reaproveitamento of organic and inorgânico material of the garbage. Optimum method of garbage treatment is considered, in relation to the environment, a time that diminishes the amount of sent garbage the sanitary aterros, and reduces directly the necessity of extration of more raw material of the nature. However, many materials cannot continued be recycled (staple fibres, in special). The recycling of certain materials is viable, but little or not practised for being economically impracticable. Some garbage forms, in special, highly toxic garbage, cannot be recycled, and needs to be discarded.

Landfill
landfill is considered a way practical, cheap to destine the urban and industrial residues, beyond treat esgotonão. Therefore, they are the used form more for treatment of residues. They use great land areas, where the garbage is deposited. However, traditionally, they make unusable some materials that could be recycled, beyond being a source of pollution of the ground, rivers and lakes and air. The pollution if must to the process of decomposition of the organic substance that generates enormous amounts of biogás, that it contains toxic methane and other components, and of chorume, liquid I contend component toxics that flue of the garbage for the ground and bodies of water (as rivers and lakes) of the region. Currently, the new aterros have been constructed in way to prevent the contamination of ground, demanding themselves it installation of waterproof blankets that prevent the infiltration of the chorume beyond the area destined to fill with earth it. The liquid that is restrained in it I fill with earth, the chorume, then is lead until a system of treatment of effluent for posterior discarding in conditions that do not attack the environment.
Incinerators
Incinerators literally incineram the garbage, reducing it it leached ashes. They are highly polluting, generating enormous amounts of pollutants, as gases that contribute to the aggravation of the effect greenhouse. It is the method used for the hospital garbage destruction, that can contain .causing agents of potentially fatal illnesses. In the century passed until middle of the Fifties it was practical common, the industrial residue and until the organic substance to be eliminated with use of great ovens for atmospheric waste of the chimneys.

Composting
It is a aerobic treatment, through which the organic substance if decomposes in seasoning or composition.
Anaerobic Digestion
Anaerobic digestion is a treatment for anaeróbica decomposition that generates biogás, that it is formed by about 50% of methane and that can be burnt or be used as combustible. The solid residue of the Anaerobic digestion can be treated aerobicamente to form composed.
Permanent Confinement
Toxic and highly lasting garbage, and that it cannot be destroyed, as nuclear garbage, needs to be treated and to be confined permanently, and kept in some place of difficult access, as excavated tunnels the kilometers below of the ground, for example.
