Firstly, the waste must divide into organic waste and inorganic waste
A. Organic waste utilization
Utilization of organic waste, such as composting (composting) waste that
can be changed easily decompose into compost is environmentally friendly.
In addition to environmentally friendly compost is also very easy in
practice students in school and at home.
In addition to easily make compost the manufacture also cost-effective.
Purpose of making compost is to make students understand how to manage
waste correctly Organic and Inorganic.
Excellent compost adds nutrients to the soil so that it can add fertility
of soil, enhances the ability to retain water in the soil, improving the system
of air spaces in the soil and enhance the holding capacity of the soil to
provide plant nutrients on plant fertility.
In composting, there are several ways, namely ....
1. Compost making natural way to do this in a way to hoard junk plants
gradually into the hole measures 1.5 x 1.5 x 1.5 meters.
Then layered with manure and sprinkle in a little ash and lime.
Later on it adds another layer of plant litter and animal waste in the
cap and so on so be razed to the ground.
The landfill waste should be moist but not too wet in the period of 2-3
months.
Where waste is already shrunk to a tenth of its original size, then the
waste is being composted manure.
2. Composting with the help of Microbes: Making compost is very easy with
the help of microbes by fermenting organic waste such as animal manure / man,
straw, rice husk, bran / bran smooth, grass, leaves, trash and other household
forth.
And commonly called Manure.
B. Inorganic waste utilization.
Garbage or waste that we produce every day, usually we throw
away without us sorted into.
This is probably because they do not know or may not want to
know that the waste can be sorted into a waste Organic and Inorganic that can be utilized into useful items.
Inorganic waste is waste that is not derived from living
things.
Inorganic waste requires a long time can not be relegated
even naturally.
Some of them Inorganic waste cans, plastic, styrofoam and
other materials glassware.
One that we can do in Inorganic waste is recycling
(Recycle).
Recycling is an attempt to process the item or items that
are not in use in order to be utilized again.
Immediately, the process or waste Inorganic Waste, Inorganic
Waste Here I describe into 4 parts:
1. Waste Plastic Waste plastics commonly used as wrapping
goods.
Plastic is also commonly used as household furniture.
Advantages goods made of plastic that is not rusty and
durable.
For example, my friends try to grave plastic garbage for
several months, then dig some more and see the land cover can be sure the waste
will remain intact.
One way is by recycling into useful goods again for sure.
Such example is used plastic buckets that can be recycled
back into plastic spoons, trash, scoop and flower pots.
Of plastic food wrappers though again we can be a craft that
purse, laptop bag, slippers, umbrellas and shopping bags.
Bottle bins can be utilized also be children's toys such as
ship-calloused example, cars and so on.
2. Trash Metal waste or waste from metal such as iron, tin,
aluminum and others can be found easily in the environment around us.
Trash cans of materials most commonly we find and the
easiest to use and useful crafts.
As a simple example, namely the processing of a trash can
drums, flower vases, key chains, piggy bank and gift box.
3.Glass
Waste or glass that is broken can be
recycled back into the original goods or other items such as a new bottle,
vase, souvenir eyes and other decorations that have artistic and economic
value.
4. Waste paper is
easily destroyed and everything seems harmless like plastic.
But the name certainly cause problems if the waste on leave
granted.
As an example of paper that littered the classroom will
inevitably lead to a sense of discomfort in the learning process. As the
processing of waste paper can be utilized to ornament boxes, book covers, photo
frames, pencil and others.
