Reusing or recycling water means that you re saving money on your water bills, because you re using less of it, and also means that you re actually using less fresh water for watering your lawn, washing your car and washing your clothes, plates and other items. Recycling does a lot of help in protecting the planet, because it helps reduce the amount of garbage we discard. Recycling is referred to as the process or re-using or re-tooling used materials, into new products or other new derivatives. The most common recyclable materials include metal, glass, textiles, paper and plastic. The amount of wood and paper that we throw in our landfills each year is more than enough to heat 50,000,000 for the next twenty years. Used aluminum beverage cans are among the most easily-recyclable items today. A used aluminum can be recycled and returned back to the grocery shelf in as little as 60 days, and recycling one aluminum can saves enough energy to power a television set for 3 hours. You can also design Styrofoam into rings or squares that the children can use as a float in the pool. Styrofoam boxes can also be used for leftovers to help germinate seeds.

In the US, the Environmental Protection Agency (EPA) and other state departments manage and oversee the laws which regulate the disposal of hazardous wastes. The EPA requires that hazardous wastes be handled with extra precaution, and should also disposed at designated facilities. Among the materials that need to be handled with extra care include medical waste, commercially-generated waste, electronic items and components, radioactive materials, ammunition, and other unknown materials.
