Document Summary
The garbage project: our garbage woes are serious but not exceptional, and can be dealt with by safe disposal methods that are already available. Biggest challenge is recognizing that the conventional wisdom about garbage is often wrong. There are 4 ways: dumping it, burning it, converting it into something usable again, and minimizing the volume of material goods (future garbage) aka source reduction: dumping has been favored everywhere. Katie kelly in book garbage, asserted that the amount of msw in u. s. annually would fill 5 million trucks that would stretch around the world twice, fill twin towers of 187 world. Problem- no way to measure or weigh more than a fraction of what is thrown out. Estimates of size of waste stream vary a lot from 2. 9 to 8 pounds per capita / day. We forget everything that is no longer there to see.
