Actually plastic has several advantages, such as strong, light, and stable. However, the plastic is difficult to decompose by microorganisms in the environment causing serious environmental pollution. To solve the problem of plastic waste, several approaches such as recycling, plastic waste processing technology, to the development of new plastic materials that can be destroyed and decomposed in the environment, known as biodegradable plastics.
Here we will discuss about waste management methods through combustion process using incinerator and recycling process to handle the combustion side product. It is expected that this method can be applied in Indonesia to deal with environmental problems caused by environmental disability (especially microorganisms) in remodeling and decomposing plastic waste.
The use of plastic continues to increase from year to year. Even in 1992, plastic waste was ranked third of all waste production in Bandung. Plastic waste itself is a waste that is difficult to degrade. It causes pollution on environmental sustainability.
During this effort to handle plastic waste is done by sanitary landfill method. This method is one of controlled waste management. Trash is discharged to the TPA (Final Disposal), then the garbage is compacted with the tractor and then covered with the ground. This will eliminate air pollution that will cause waste. At the bottom of the place is equipped leachate channel system that serves as a waste liquid waste channel that must be processed first before discharge into the river or into the environment.
This method is not effective because it often causes pollution of ground water and the environment around the landfill. Even recently, in Bandung there was a disaster due to landfill that does not meet the requirements. In addition there is the possibility of gas that can cause air pollution. Gases that may be produced are: methane, H2S, NH3 and other H2S and NH3 gases although the numbers are small, but can cause unpleasant odors that can damage the respiratory system of plants and make plants lack of oxygen gas and eventually die.
In the process of landfilling, waste should be processed first in a way destroyed in order to minimize the volume of waste in order to facilitate the compression of garbage. To do this would require additional work that led to additional funds.A better solution needs to be considered. The solution includes efforts to reduce plastic waste production and waste processing efforts that already exist.
Efforts to reduce waste production
Efforts to reduce waste
(1) Use of biodegradable plastics, (2) Much research has been done to obtain biodegradable plastics.
The waste segregation should start
Combustion results are gases and combustion residues. The decrease in the volume of solid waste from combustion can reach 70%. This method is relatively more expensive than sanitary landfill, which is about three times as much
- Requires a relatively small area compared to sanitary landfills.• Can be built near industrial sites.
- The combustion residue is relatively stable and almost all of them are inorganic.
- Can be used as an energy source, both for steam generators, hot water, electricity, and metal
The drawback lies in the expensive investment, labor, repair and maintenance costs, and still removing residues, also generating gas.In general, the combustion process inside the incinerator is:
- Burnable waste is inserted in a container or supplier.
Nextthe garbage is set so that it is flat and then put into the burner stove.
- Ash combustion results, can then be used as a waste cover on landfill.
- While the results of gas will be channeled through a chimney that is equipped with a scrubber or accommodated to be utilized as an energy generator
