Description

Municipal solid waste recycling system {RENEWABLE AND COMPOSTING SYSTEM FOR MUNICIPAL SOLID WASTE}

The present invention relates to a system for recycling urban solid waste, and more particularly, to minimize the landfill amount of final waste and to provide high-quality quality through treatment such as screening, crushing, and drying of urban solid waste generated from human activities or natural cycles. It relates to a system for recycling municipal solid waste into fuel products, etc.

In general, municipal solid waste (MSW) refers to materials that are no longer needed for human life or industrial activities, such as garbage, combustion ash, sludge, waste oil, waste acid, waste alkali, and animal carcasses.

For example, municipal solid waste refers to waste in a solid state, which is distinguished from liquid and gaseous waste among wastes generated in cities, rural areas, etc., including domestic waste under the current Waste Management Act, and It may include industrial wastes having a configuration, and when integrated with the domestic wastes and industrial wastes, it may also include wastes designed to discharge facilities within a range that does not impair the identity of the composition.

These municipal solid wastes include both organic and inorganic materials, such as food waste, paper, wood, waste plastic, waste vinyl, and waste iron. etc. are classified as inorganic waste.

Conventionally, most household waste was disposed of by landfill or incineration.

However, in the case of landfilling municipal waste containing a large amount of organic components, odors such as methane gas are generated in the landfill due to the decomposition of organic components, and water quality deteriorates due to contamination of leachate and landfill of non-degradable materials such as waste vinyl Soil contamination is a problem.

In addition, since the conventional landfill is already saturated, there is a problem in that a new landfill site must be secured in order to continue the existing landfill method.

On the other hand, as a way to treat domestic waste, there is a case where household waste is incinerated.

However, in the case of incinerating municipal waste containing a significant amount of wet waste such as food, there is a problem in that harmful components such as dioxin and furan are discharged, causing secondary environmental pollution.

In this regard, an alternative to installing a pollution prevention facility to prevent the generation of harmful substances has been proposed, but there is a problem that is not suitable from an economic or practical point of view.

Accordingly, a method of recycling only food waste after separate collection has been proposed, but in this method, there is a restriction in that food waste must be separated and collected, and even when food waste is separated and treated, the remaining waste is landfilled or incinerated. There remains a problem that needs to be dealt with separately.

As an example, municipal solid waste management is currently the main responsibility of local governments, which includes garbage from households, non-hazardous solid waste from industry, commerce and utilities, market waste, yard waste and street litter. is defined as

Recently, government agencies have started to specify regulations for the disposal of waste, landfill being the main method of waste disposal, which is very inefficient and when poorly buried landfill decomposes, harmful substances may be released into the environment.

Therefore, landfill has inherent problems such as unavailability of land, deterioration of groundwater, and contamination.

The most commonly considered alternative to such landfill methods is mass incineration, which produces a variety of pollutants that, in improperly controlled or high concentrations, may cause respiratory distress and disease.

These pollutants are generated by the incomplete combustion of municipal solid waste and the burning of plastics. The treatment of municipal solid waste is expected to increase in terms of population growth, population concentration in urban and suburban areas, and an increase in the number of industries generating solid waste. It is becoming an increasingly serious problem.
