Solid Household Waste Management

Утилизация твердых бытовых

In addition to the world ' s most common methods of mechanized decontamination and reprocessing of TBTs - incineration, aerobic composting and a combination of these two methods - alternative technologies for the disposal and processing of TBTs are being developed around the world to obtain new materials and extract valuable waste fractions. Integrated work intensified TB with the extraction of valuable secondary materials, the anaerobic discharge of fuel and organic fertilizer. The extraction technology from the TBT of burning fractions and the manufacture of fuel brackets or granular fuels has been developed and implemented, the TBT press for building blocks, etc.

The main complete trim is the maximum mechanized extraction from the total mass of the TBT of the waste components. Each specific scheme uses its set of technology equipment that allows for more or less extraction of waste fractions. In the pill. 1 Different ways of extracting waste fractions from domestic waste are presented.

TBT offences

Method of recovery

Black metal

Electrical separation

Colour metal

Variable " running " magnetic field extraction; fragmentation and pneumatic separation

Paper

Pneumatic split of fractions by velocity in the air flow; hydropulpation and deposition of thin cohort fractions

Textile

Dry extraction in cylindrical groves with hooks (wilters); separation by maintaining strength (as opposed to paper) when laden and washed

Synthetic film

Pneumatic separation at the velocity of the air flow; separation by maintaining the strength of the wet and retiring; electrostatic separation

Glass

Mocreai separation in cyclones; pneumatic section in the upstream air flow at turn speed; separation in meters with reflective drip and ballistic properties

Plastics and cardboards

Optical separation of bottles and carton packages


The separation of TBTs is mainly seen as a way to improve " traditional " processing techniques (the quality of composts is improved through the removal of ballast fractions, the debris-burning bulb is reduced, and not only as a method for the disposal of some valuable TBT components.

Thus, the efficiency of the waste management method, which focuses on the extraction of waste components, is determined by the procurement value of the components identified, taking into account their quality. A case in point is a few fundamentally different technology-tested integrated TBT separations.
