Solid Waste

In a general sense of waste, solid waste and garbage is as follows.

  1. Waste is the material remaining on an activity and / or production process. Type of waste in the hospital is composed of solid waste, liquid waste, radioactive waste and waste gas.
  2. Solid waste (solid waste or refuse commonly called garbage. Solid waste does not include human waste.
  3. Garbage is all of the substance of objects arising from the actions of man which is discarded because it is not used or desired by the owner.

What is a Solid Waste?

Solid waste is defined as the rest of the activities of human and/or natural processes that shaped solid. Or, solid waste is the waste that is solid composed of organic material and inorganic material that is considered no longer useful and should be managed so as not to harm the environment and protect the investment of development.

Then based on the Term Environment for the Management, solid waste is a material which is wasted or thrown away from the source of the result of human activity and natural processes that do not yet have economic value. Thus, the solid waste is the rest of the/a result of human activity, which is shaped organic and inorganic substances that can harm the environment so that the necessary management and processing. Solid waste can be generated from different types of activities such as residential, office, industrial, schools, markets and other public facilities.

Type-The Type Of Solid Waste

Solid waste management is a series of activities which include storage, collection, transport, waste treatment and final disposal or hoarding basil to such processing.

Based on its composition, the solid waste can be divided into two, namely:

1. Solid Waste Wet

Solid waste damp is a solid waste that is shaped organic ingredients that are easily decomposed by microorganisms. The process of decomposition will occur when solid waste is left in a wet state and is at the optimum temperature of about 200-300C. In general solid waste wet utilized as compost. Examples of solid waste is wet, the rest of the foods, the vegetables, the skin soft fruit, and leaves.


2. Solid Waste Dry

 Solid waste dry waste solid-shaped organic and inorganic materials. In general solid waste dry do not quickly decompose microorganisms so that it is difficult in a state of decay. Solid waste dry inorganic can be upcycled into other products that are useful. Examples of solid waste is dry, like paper, plastic, containers of food or drink, cans, wood, metal, and glass or a glass.


But, solid waste can be classified into six groups as follows:

  • Organic waste easily rot (garbage), namely solid waste semi-wet, in the form of organic ingredients that is easy to rot or decompose microorganisms. Examples are: the rest of the food, the rest of the kitchen, vegetable waste, fruit peels fruits
  • Waste inorganic and organic’t rot (rubbish), namely solid waste inorganic or organic dry enough that it is difficult to decompose by microorganisms, so it is difficult to decompose. Examples are: cellulose, paper, plastic, glass, metal.
  • Trash the ashes (ashes), namely solid waste in the form of ashes, usually the result of combustion. Trash is easily carried by the wind because it is lightweight and not easy to rot.
  • Waste animal carcasses (dead animal), like all waste in the form of dead animals, such as rats, fish and livestock to die.
  • Trash sweep (street sweeping), namely solid waste results of the sweep of the street containing a variety of trash scattered in the streets, just as the foliage, paper and plastic.
  • Industrial waste (industrial waste), like all the solid waste that originate from industry. The composition of the waste depends on the type of industry.

The handling of solid waste can be distinguished from the usefulness or function of the solid waste itself. Solid waste there can be recycled or used again as well as having economic value such as plastic, textile, metal scraps, but there are also that cannot be used again. Solid waste that can not be used again usually thrown away, burned, or dumped unceremoniously. Some of the specific industry of solid waste that is produced sometimes create new problems associated with the place or the broad areas that needed to accommodate the waste.
