Types of Waste in the Environment

The impact of careless and not properly managed waste disposal is in the form of soil, water and air pollution, and flooding.

Thus it can be said that this waste management aims to prevent, overcome pollution and damage to the environment, restore the quality of polluted environment, and improve the capabilities and functions of environmental quality.

Examples of waste management are as follows:

Solid waste

As organic waste will rot resulting in a foul odor that invites animals to arrive, generally these animals can spread disease, and can pollute the soil.

Non-decomposed and non-organic organic waste which is disposed of into water bodies (rivers, lakes, seas), will pollute the water, even if dumped into rivers it can cause flooding.

Household waste and the like in urban areas are managed by the Local Government or private Sanitation Service.

These wastes (other than feces) are collected in Temporary Shelter (TPS), then from the TPS they are taken to recycling or processing or integrated waste processing facilities or final waste processing sites. Ideally, but in reality there is still pollution due to garbage disposal.

The final landfill (TPA) in big cities in Indonesia is only a place for garbage collection, without further treatment.

The local government starts to make integrated processing sites by preparing waste sorting, recycling sites, and incineration (controlled burning).

Previously the landfill was only to dispose of garbage, the community perceived that the integrated processing site was only camouflage, as a result the people living in the surrounding area were also doing a lot of rejection of the existence of this integrated waste processing site.

Wherever it is disposed, it will contaminate its landfill, both on the ground and in the water.

Therefore, wastewater treatment must be carried out both from housing and industry.

In the industrial area wastewater is treated with a Waste Water Treatment Plant (WWTP).

In housing, the disposal of latrine is septic tank, this is a form of processing individual sewage, while other wastewater goes into the sewers.

Fecal Waste Treatment Plant (IPLT) or Septage Treatment Plant (STP) is a form of communal sewage treatment.

IPLT uses a biological system with an oxidation pond equipped with a motor.

The results of the IPLT whether water or mud can be returned to nature safely, the mud can be used as compost. In addition, IPLT in densely populated settlements can produce biogas.

Biogas is a gas that is fermented by organic matter by anaerobic microorganisms.

Biogas toilet is a toilet waste that is used to be processed into methane (CH4) which is then used as cooking fuel by the local community.

This biogas toilet is a further development of biogas technology for livestock waste.
