Science 5

1. PROPER WASTE MANAGEMENT

2. WASTE MANAGEMENT Refers to the process by which garbage is properly collected, transported, and disposed of. In the Philippines, waste management is a major environmental concern, because of the tons of garbage that are thrown every year into the dumpsites and it is already filled up. Due to increase in population, many materials are used and the materials are dump as garbage. Also, decreasing of the resources on Earth. To address the concern on waste management, five R’s is introduced: reduce, reuse, recycle, recover, and repair.

3. REDUCE Use only the resources that is truly need, use fewer resources, and throw away fewer things, therefore help to reduce the world’s waste. There are different ways to do that.

4. 1. During the opening of class: parents should only buy exact tamount of school supplies. Hoarding is okay but when you hoard and others are not used, they may end up as surplus of supplies that is not useful anymore. 2. T ransportation: if you are going a nearer place, walking or biking is more efficient way rather than riding a vehicle. When you walk, less money spent, less fuel energy used, and lesser marine natural habitat destructions. Because fuels are gathered underneath the ocean. You can help to preserve our natural resources.

5. 3. In the house: unplug or turn off gadgets, appliances that is not in used. More appliances playing, more electricity being used up. And electricity is generated from burning fossil fuels. It takes thousand years to replenish f ossil fuel. 4. Using of paper; instead of printed outs projects or assignment, send them thru emails, because more papers produced, more trees are cut off. We should reduce the usage of papers. 5. Do not play with water. Close the faucet after use, when there is leaking faucet, repair them immediately to avoid wastage of water.

6. REUSE To use it again It extends the lifespan of materials before throwing or recycling it. It can be observed in different ways:

7. Do not throw the books, they may be useful for your younger siblings. If not, donate them to be used by others instead of throwing it. Do not throw empty back papers, it can be used as scratch paper for computing math problems. Donate the clothes you no longer wear and the toys you no longer played with.

Wheels into garden pots. Old clothes to rugs. Glass material and metal scraps molded (by heating) to glass bottles and metal sheets.

11. RECOVER It involves getting the materials or substances from garbage and having these processed then reused. It can be observed in different ways:

12. Damage cellphones or any gadgets must be sold to any electronic shops. Some parts can be useful in making new gadgets. Ink cartridge, instead of buying new one, you can refilled it with new ink.
