Characteristics of the waste in Schools
School
as a gathering place for many people to be the largest waste producer in
addition to the market, household, industrial and institutional. In general,
waste can be separated into:
1. Organic waste /
nonperishable comes from food scraps, vegetable scraps and fruit skins, fish and meat, garden waste (grass,
leaves and twigs).
2. Inorganic waste
/ nonperishable form: paper, wood, fabric, glass, metal, plastic, rubber and
soil.
Waste
generated mostly school is kind of dry waste and wet waste only slightly. Dry
waste is produced mostly in the form of paper, plastic and a little metal.
While the wet garbage from a tree fallen leaves, food scraps and food wrapping
in banana leaves.
Waste management
1. Sorting is
separated into groups of organic and non-organic waste and placed in different
containers.
2. Processing by
implementing the 3R concept:
Reuse (reuse) that is using a
particular waste is still possible to use [reuse old bottles].
Reduce (reduction) that is trying
to reduce everything that can lead to waste and reduce the waste that already exists.
Recycle (recycled) that is using
certain waste to be processed into a more useful item [recycling organic waste into compost].
3. For waste that
can not be addressed within the scope of the school, gathered to place
Temporary Shelters (TS) has been provided for further transported by the janitor
to the Final Disposal (TD).
Waste dumped TS
placed based waste sorting has been done. This is done because the rapid decay
of organic waste while non-organic waste takes longer to decompose so require
special treatment. For TS are intentionally provided by the school polling
station should be equipped with a system hole cover so that rodents, insects,
and certain animals not enter into it, and also to avoid the smell of garbage
that could interfere.
To facilitate the
range is usually also provided small bins are placed in places easily
accessible as temporary shelters waste before disposal to the polls. Garbage
disposal in the garbage should also be separated into organic and inorganic
trash when it's full and must be immediately discarded to the polling station
or directly taken up by the janitor for disposal to landfill.
Designing Waste Management in Schools
In the school
environment, waste management requires a serious attention. With the
composition of most of the residents are children [the learners] do not rule
out the management was not optimal. But also can be used as a medium of learning
for its students. One of the parameters of a good school is environmentally
sound.
Organic waste can
be processed into compost. The process is easy and simple. Elementary school
age children can work on their own until high school. With wet waste composting
at school can be a medium of learning for students. At least the children will
learn about the Natural Sciences. Children will also learn to appreciate the
environment. They will learn how to waste it can be beneficial to humans not
only as something dirty and disgusting. The resulting compost can be used to
fertilize plants that exist or as a mixture of planting medium in pots.
Waste paper
generated a lot of that type HVS. This paper types among scavengers have the
highest prices. Not to mention cardboard, paper food wrappers and other paper
types. Especially for waste paper, can do two things to manage.
1. The first is
recycling as its own management. Waste paper can be recycled fairly easily.
Scrap paper cut into small pieces and soaked in water. The next process is the
blender to turn into pulp. This is where creativity is needed. Pulp can be used
as recycled paper or can be used as the basis of creativity, such masks pigora
paper or forms.
2. The second form
of management is sorting system for sale. HVS manifold paper separated from
other types such as newspaper, cardboard and kerdus. Waste paper that has been
sorted earlier sold to scavengers. Scavengers will periodically come to the
school to pick up the paper.
Another type of
rubbish in the school is pretty much plastic. Garbage is mostly made up of
plastic wrap and a bottle of mineral water. For the latter type are now much
sought after. Used bottles are made from PET plastic can be recycled into
plastic pellets. Similarly, the former beverage cans are made of metal. This
type of waste should also be sorted, collected for sale. Children can also be crafted
creative crafts or wall hangings.
By sorting system
is expected students to learn how rubbish the original dirty and disgusting
apparently has a sale value. Economic subjects can be learned from a pile of
garbage in school. The students will realize that there are job opportunities
in the surrounding areas, not just the look but can also be created.
In the design of
waste management in school, students need to be actively involved. This can be
done by forming teams assigned to a scheduled basis. Periodic exhibitions and
competitions can be done to raise awareness of waste management. Writing in a
blog or bulletin board is a good exercise to cultivate the souls manage waste.
Thus emerged a new awareness that, "Garbage is not a problem, but an opportunity".
