ReCycling
Recycling turns materials that would otherwise become waste into valuable resources. Collecting used bottles, cans, and newspapers and taking them to the curb or to a collection facility is just the first in a series of steps that generates a host of financial, environmental, and social returns. Some of these benefits accrue locally as well as globally.
ReUse
The most effective way to make an impact on waste is simply to reuse an item so it stays out of the waste stream and another, new item doesn't need to be made to replace the discarded one.
ReBuilding
Many of the items brought in are old and out of date, but by no means unusable. Many just need a quick repair or some newer parts to improve performance.
