Garbage is unwanted material remaining after the end of a process. Trash is defined by a man in the degree of application, in the processes of nature there is no concept of actual garbage, only products that are produced after and during the natural process takes place. However, because human life is defined in the concept of the environment can be divided according to type of waste-kind.
The types of waste
Based on the source
By its nature
Organic waste - can be parsed (degradable)
Inorganic waste - do not decompose (undegradable)
A. Organic waste, namely waste such as leftover perishable foods, vegetables, leaves, and so forth. This waste can be further processed into compost; 2. Inorganic waste, ie waste that does not easily decompose, such as plastic food packaging containers, paper, plastic toys, bottles and drink cups, cans, wood, and so forth. This waste can be used as commercial waste or waste products to be sold laiannya. Some inorganic waste that can be sold is a plastic food packaging containers, used beverage bottles and glasses, cans, glass, and paper, either newsprint, HVS, and cardboard;
Based on the shape
Trash is either solid or liquid material that is not used anymore and discarded. According to the waste form can be divided as:
Solid waste means any waste material other than feces, urine and liquid waste. Household waste can be either: kitchen waste, garden waste, plastic, metal, glass and others. According to this waste material is grouped into organic and inorganic waste. Organic waste is waste that comes from items that contain organic materials, such as the remains of vegetables, animals, paper, pieces of wood from household appliances, pieces of twigs, grass at the time of cleaning the garden and so on.
Based on the ability of nature is broken down by (biodegradability), then it can be subdivided into:
Biodegradable: ie waste that can be described completely by the process of either aerobic or anaerobic biological, such as kitchen waste, animal remains, waste and plantation agriculture.
Non-biodegradable: the waste that can not be explained by biological processes. Can be subdivided into:
Recyclable: waste can be recycled and reused because it has economic value such as plastic, paper, clothing and others.
Non-recyclable: trash that has no economic value and can not be processed or converted back like tetra packs, carbon paper, thermo coal and others.
Liquid waste is a liquid material that has been used and is not necessary to go back and dumped into landfills.
Black waste: liquid waste resulting from the toilet. This waste contains harmful pathogens.
Household waste: liquid waste resulting from the kitchen, bathroom and laundry. This waste may contain pathogens.
Waste can be in any phase of matter: solid, liquid, or gas. When released in two phases of the latter, especially gas, can be regarded as waste emissions. Commonly associated with pollution emissions.
In human life, large amounts of waste coming from industrial activities (also known as waste), such as mining, manufacturing, and consumption. Almost all industrial products will become waste at a time, with the amount of waste which is roughly similar to the amount of consumption.
to prevent the liquid waste is not waste factories such haphazardly throw into the ditch.
Waste produced in the wild are integrated through natural recycling processes, like dead leaves in the woods that break down into soil. Beyond the wildlife, the waste can be a problem, such as dead leaves in the neighborhood.
Human waste (UK: human waste) is the term used for the results of the human digestive tract, such as feces and urine. Human waste can be a serious hazard to health because it can be used as a vector (means of development) diseases caused by viruses and bacteria. One of the major developments in human dialectic is the reduction of disease transmission through human waste in a hygienic way of living and sanitation. Included are the development of the theory of distribution pipes (plumbing). Human waste can be reduced and reused for example through waterless urinal system
Consumption of junk
Consumer waste is waste generated by the (human) users of the goods, in other words, the waste is dumped into the trash. This is a general waste of human thought. However, the amount of waste this category is still much smaller than the waste generated from mining and industrial processes.
Nuclear waste is the result of nuclear fusion and nuclear fission of uranium and thorium that produce very harmful to the environment hidupdan humans. Therefore, nuclear waste is stored in places that are not high potential to perform activities of designated places are usually former salt mines or the sea floor (though rarely, but sometimes still do).
