Waste Management pattern is still adhere to the old paradigm where the garbage is still regarded as something useless, worthless, economical and very disgusting. Community as a source of waste was never aware that the responsibility for the management of waste generated is the responsibility himself.

If the garbage – garbage that this remarkable start to be a problem for humans, then humans are aware of the lack concern for trash and began to cause panic and the haunt where – where, not knowing what to do about it.

Trash is a consequence of human activity, because every human activity must generate waste or garbage. The amount or volume of waste is proportional to the level of our consumption of goods / material that we use everyday. A day every citizen of the city generates an average of 900 grams of waste, with the composition, 70% of organic waste and 30% inorganic. The increase of population and lifestyle are very influential on the volume of waste.

Waste generated by the (human) users of the goods, in other words is the rubbish that the garbage, although still much smaller than the waste generated from mining and industrial processes, but it is a waste material that has always been the case for human .


The principles also can be applied in tackling waste for example by applying the 4R principle, namely:

· Reduce ; possible do to minimize the goods or materials that we use. The more we use the material, the more waste produced.

· Reuse ; best to choose items that can be used again. Avoid using disposable items (disposable, throw). It can extend the use of the goods before they become waste.

· Recycle : wherever possible, the goods have not useful anymore, can be recycled. Not all items can be recycled, but it’s been a lot of non-formal industries and industries that utilize household waste into other goods.

· Replace ; carefully the things we use everyday. Replace goods that can only be used once the goods are more durable. Also carefully so that we only wear items that are more environmentally friendly. For example, replace the bag when plastic bags us with shopping cart, and do not use styrofoam because the two materials can not be degraded naturally.

Rather than assume that people will generate an increasing amount of waste, waste minimization should be a top priority.


In general, most of the waste produced in Indonesia is wet garbage, which covers 60-70% of the total waste volume. During this waste management, especially in urban areas, do not run efficiently and effectively as centralized waste management, to dispose of the waste disposal system is mixed.

Waste disposal should be done prior to the grouping of waste by type and its form so it is easy to be recycled and / or used (wet waste, dry waste is sorted out again into the glass and plastic bottles, aluminum cans, and paper). For each ingredient separate bins are provided, there is a plastic trash, like glass, metal tub, and bath for the paper. Waste segregation starts from the household level, and the apartment market. When the difficulty in choosing the minimal trash trash trash is separated between wet (easily decomposed) and dry waste (plastic, cans, etc.)

The government itself provides a garbage collector cars that have been disaggregated according to grouping. Government responsible for organizing the collection of garbage was to be submitted to the recycling plant. Residual waste can be processed by the buildup of (left to rot), composting (fertilizer made), arson. Of the three ways of waste management takes the usual wet Final Disposal is quite broad. In addition the effects are less common good such as environmental pollution, the source of the seeds of disease or the occurrence of landslides.


Other than the management of the above there are other ways to be performed by the City of London is waste utilized as a source of electrical energy (Waste to Energy) or better known as Power Plant Waste.

Waste to Energy Concepts (Waste to Energy) or (Power Plant waste) are summarized as follows:

1. Waste sorting

Sorted garbage to utilize the waste can still be recycled. Inserted into the furnace residual waste incinerator to be burned.

2. Incinerator

Incinerator combustion technology that enables effective and safe for the environment. Combustion temperature is maintained in a high degree of combustion (above 1300 ° C). Smoke from burning too controlled to be in accordance with quality standard exhaust emissions.

3. Heat recovery

Results incinerator will generate heat that can be used to heat the boiler. The resulting steam is used to rotate the turbine and electric generator next move.

4. Ash utilization

The remainder of the waste incineration process is ash. Volume and weight of the resulting ash is estimated that only about 5% by weight or volume of waste was in before the burn. This ash will be utilized for raw brick or other building materials after processing and quality in accordance with building materials.

Major cities in Europe, America, Japan, Netherlands, etc. Waste energy has been made since last decades, and the results are acknowledged to be more able to solve the waste problem. Pollution from PLTSa that had been feared by the people actually can be anticipated by the state that have used PLTSa first. Pollution-pollution such as:

· Dioxin

Dioxin is a dangerous organic compounds that are by-products of chemical synthesis on a process of combustion of organic matter mixed with materials containing halogen elements at high temperatures, such as plastic in the trash, can generate dioxins at a relatively low temperature such as burning at the landfill.

PLTSa already equipped with emission and effluent treatment system, so that the pollutant is released under the quality standard applicable in Indonesia, and do not pollute the environment.

· Residues

The results from the combustion of waste is a residue or bottom ash (bottom ash) and fly ash (fly ash) that B3 waste, but the results of studies and testing for ash utilization PLTSa has been done in other countries. Singapore is currently used to make the island, and in 2029 Singapore will have a new island covering an area of 350 Ha.

PLTSa will use the ash as raw material for brick or building materials.

· Odor

Any garbage that has not undergone the process will remove the unpleasant smell good when transporting and piling and would interfere with the general public.

To avoid odor emanating from the waste will be a separate path to the location PLTSa through Toll roads, surrounding buildings PLTSa trees will be planted to form the Greenbelt (green belt) area of 7 hectares.
