Garbage is defined by humans according to the degree of disuse, the natural processes actually no concept of waste, only products that are produced after and during the natural process take place.
By its nature, there is organic waste that can be parsed.
Like the rest of the junk food, vegetables, dried leaves, and so on.
This garbage can be turned into compost. and there are also inorganic waste that can not be unraveled.
Such as plastic food packaging containers, paper, plastic toys, bottles and drink cups, cans, wood, etc.
And based on its shape no solid waste, liquid waste, waste of natural, human waste, trash consumption, and radioactive waste.
Solid waste is any waste material other than feces, urine and liquid waste.
May include household waste, such as kitchen waste, garden waste, plastic, metal, glass and others.
Liquid waste is a liquid material that has been used and do not need to use again and dumped into landfills.
Like the black waste generated from household toilets and waste generated from the kitchen, bathroom and laundry.
While natural waste is waste that is produced in integrated wildlife through natural recycling process, such as dead leaves in the woods that break down into the soil.
Human waste can be a serious hazard to health as it can be used as a means of progression of the disease caused by viruses and bacteria.
Trash consumption is waste generated by the (human) user of goods, in other words, is the garbage being dumped into the trash. It is a common man's trash. Nevertheless, the amount of waste this category is still much smaller than the waste generated from mining and industrial processes.
Radioactive waste is the result of nuclear fusion and nuclear fission that produces uranium and thorium are very harmful to the environment as well life and humans. Therefore nuclear waste stored in places that are not high impact activities designated places usually mined salt or sea floor (although rare but sometimes still do).
That's why we have to manage our school waste.
So that waste into harmless and useful, then we have to process waste.
Waste management objective is to convert the waste into a material that has economic value and process waste materials not to be harmful to the environment.
Disposal methods are very diverse.
There are hoarding land in a way that is not buried in the ground unused, mining pits, or holes in the hole.
There are also methods that collect recycling and reuse of waste disposed, for example, collected used bottles back for reuse.
Collection can be made from the waste that has been separated from the initial (litter box / junk vehicle specific), or from the waste is mixed.
Biological processing for compost, or known as composting.
The result is compost that can be used as fertilizer and methane gas that can be used to generate electricity.
Energy recovery by way of making fuel, or indirectly by way of an advanced process other types of fuel.
Last avoidance and reduction methods include reuse of second-hand goods, repair defective goods, designing products that can be refilled or can be reused (such as cotton shopping bags replace plastic bags), encouraging consumers to avoid using disposable items (paper towels) , and designing products that useless material for the same function (weight reduction beverage cans).
