At school there are also a lot of rubbish. Many students who do not want to care about the school environment. They do not feel guilty if the litter. Although many the trashcan they also do not want to dispose of waste in place. Many students now eat at break time do not throw trash in the trash. They leave trash everywhere.
Many students do not realize the cleanliness of the school. They do not know the importance of school hygiene. If schools are clean, then the learning activities will be fun. Clean school would make us comfortable in learning.
There are several ways that can be practiced at school. One is to separate the trash into three parts. Scholls can provide three trashcans. For example, the green bin is for waste derived from fruits, vegetables and leaves which decompose quickly or often referred to as kitchen waste. This junk often we know called organic waste. We can also provide a hole to bury the trash. After we filled the hole back cover with soil. Waste that has been buried will rot and good to be a fertilizer, which is often referred to as compost.
For example the red cans for garbage broken glass, plastic bottles, cans or trash that can not decompose or can not be burned. This trash can we choose if we are still intact can sell and that can not be sold also can we put in the hole that has been dug up and then we grave from becoming breeding grounds for dengue mosquitoes.
As for the yellow bin is for waste consisting of paper or flammable waste. This type of waste is unnecessary every afternoon we burn. This trash could actually be recycled.
How to handle the waste in the school :
1. Separate organic and inorganic waste.
2. Held a race hygiene.
3. Recycling bins can still be processed into useful items.
4. Students are encouraged not to bring junk into the classroom.
5. Students are given a witness, if the garbage. Sanctions clearing trash for a month
Based on the nature of waste is divided into two :
Organic waste and inorganic waste.
Organic waste is easily decomposed waste such as food waste, vegetables, dried leaves, and so on. This garbage can be turned into compost.
Inorganic rubbish is not easily decomposed litter, such as plastic food packaging containers, paper, plastic toys, bottles and drink cups, cans, wood, and so on. This garbage can be used as commercial waste or garbage to be sold other products. Some inorganic waste that can be sold are plastic food packaging containers, bottles and glasses former beverage, cans, glass, and paper, whether newpaper, and cardboard.
Based on the ability parsed by nature (biodegradability), it can be subdivided into :
1. Biodegradable : the trash that can be perfectly described by the process of either aerobic or anaerobic biological, such as kitchen waste, animal remains, waste and plantation agriculture.
2. Non-biodegradable : the waste that can not be broken down by biological processes. Can be subdivided into :
- Recyclable : waste that can be processed and reused because it has economic value such as plastic, paper, clothing and others.
- Non-recyclable : garbage taht has no economic value and can not be prepared or amended return as tetra packs, carbon paper, thermo coal and others.
How to tackle litter
1. Reduce
Minimize the goods or materials that we use. The more we use the material, the more waste is generated.
2. Reuse
Choose items that can be used again.
3. Recycle
Items that are not useful in recycled again.
4. Replace
Replace items which can only be used once the goods are more durable.
