"Trash"
Waste is an unwanted waste material
after the end of a process. Waste is defined by humans according to the degree
used, 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 the concept of the Trash the environment
can be divided according to the types.
By its nature:>
1. Organic waste - can be parsed (degradable)
2. Inorganic waste - do not decompose (under-gradable)
1. Organic garbage, e.g. waste that easily decompose such as food scraps,
vegetables, leaves, and so on. This garbage can be further processed into
compost.
2. Inorganic garbage, e.g.waste that is not easily decompose, such as
plastic food packaging containers, paper, plastic toys, bottles and drink cups,
cans, wood, and so on. Trash can be used as commercial garbage or trash
to be
sold as another products. Some nonorganic waste that can be sold is a plastic
food packaging containers, used beverage bottles and glass, cans, glass, and
paper, either newsprint, HVS, and cardboard.
Based on the form:>
Trash is either solid or liquid material that is not used anymore and
discarded. According to the waste form can be divided as:
a. Solid Waste
Solid
waste is 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 the 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 parsed by nature (biodegradability), then it
can be
subdivided into:
1. Biodegradable: ie waste that can be described completely by the process of
either aerobic or anaerobic biological, such as kitchen waste, animal remains,
garbage farms and plantations.
2. Non-biodegradable: e.g. waste that cannot be explained by biological
processes. Can be subdivided into:
o Recyclable: trash can be recycled and reused because it has economic value
such as plastic, paper, clothing and others.
o Non-recyclable: trash that has no economic value and cannot be processed or
converted back like tetra packs, carbon paper, thermo coal and others.
Liquid Waste
Waste liquid 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. Trash contains harmful
pathogens.
• Domestic waste: liquid waste generated from the kitchen, bathroom and
laundry. This garbage may contain pathogens.
Waste of natural
Waste that is produced in integrated wildlife
through natural recycling processes, like dead leaves in the woods that break
down into soil. Outside of wild life, this waste can be a problem, such as dead
leaves in the neighborhood.
Human garbage
Garbage man (UK: human waste) is the term commonly used against the results of
human digestion, such as feces and urine. Human waste can be a serious hazard
to health because it can be used as a vector (means of progression) of disease
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 the development of the theory
of distribution pipes (plumbing). Human waste can be reduced and reused for
example through a waterless urinal system.
Waste Consumption
Trash consumption is waste generated by the
(human) users of goods, in other words is rubbish dumped in the trash. This is
a general waste of human thought. Even so, the amount of waste this category is
still far smaller than the waste generated from mining and industrial
processes.
"Waste Management"
Waste management is the collection, transportation, processing, recycling, or
disposal of waste material. This phrase usually refers to waste materials
resultant from human activities, and usually managed to reduce their impact on
the environmental, health or beauty. Waste management is also done to restore
natural resources. Waste management can involve solid, liquid, gaseous, or
radioactive method and special skills for each type of substance.
Objectives:>
Waste management is a necessary process with two objectives:
• convert the waste into material that has economic value (use of waste), or
• process waste in order to be a material that is not harmful to the
environment.
Recycling Methods
The process of making goods that still have value for reuse of waste referred
to as a cycle recycling. There are several ways, first is to take waste
material to be processed again or take the calories from materials that can be
burned separately generate electric. Method a new method of recycling continues
to be found and will be explained below.
Examples of recycling:
The benefits of waste management:>
1. Saving natural resources
2. Energy savings
3. Saving landfill
4. Beautiful environment (clean, healthy, convenient)
5. Reduce pollution
Disaster waste is not managed well:>
1. Avalanche pile of garbage
2. Source of disease
3. Environmental pollution
4. Cause flooding
Waste Management in Schools
Stages of waste management in schools is:
a. Prevention and reduction of waste at the source. This activity begins with
the activities of sorting or separation of organic and inorganic by providing
organic and inorganic trash in every school district.
b. Recovery of waste consisting of:
1. Utilization of organic waste, such as composting (composting) waste that can
be changed easily decomposed compost became an environmentally friendly way to
preserve the function of the school district. Based on the results of studies that
by doing activities that the composition of organic waste composting to 70% can
be reduced up to 25%.
2. Utilization of inorganic waste, either directly or indirectly. Recovery of
direct, as the craft-
making raw material from used goods, or
recycled paper. Other recovery indirectly, such as selling used goods such as
paper, plastic, cans, old newspapers, bottles, glasses and bottles of drinking
water in containers.
3. Final waste disposal sites. Residual waste that can not be utilized
economically both from composting activities and the utilization of inorganic
waste, the number reached + 10% should be disposed of to landfills end (TPA) in
schools.
In addition to creating a healthy condition of the school, the school must meet
the criteria, such as cleanliness and ventilation of the room, cleanliness of
the canteen, toilets, showers, sinks, implementing health services, health
education, guidance counseling and management of community participation.
