Integrated waste management (IWM) is the waste management strategy currently
employed throughout the United States. This can be defined as the complementary
use of a variety of practices to safely and efficiently handle municipal
solid wastes (MSW) from residential, commercial and institutional sources.
IWM practices currently include:
- source separation, recycling, composting (aerobic digestion - including
vermicomposting - and aneaerobic digestion), incineration and combustion,
and landfilling.
Waste generators (residences, businesses, municipalities) typically
pay a tipping fee to have waste collected, hauled off site, and processed.
Processing usually involves separating waste into materials which can
be recycled, composted, incinerated for waste-to-energy, and finally
disposed of in a landfill. Tipping fees are charged by the tonnage,
so
the lighter the waste content the cheaper it is to be hauled and the
cheaper it is for the generator. Currently the largest portion of the
waste stream by volume is organic residuals, the heaviest segment of
which is food waste. For this reason, it behooves individuals and municipalities
to compost or otherwise recycle as many organic materials as possible.
Unfortunately, current recycling levels average only 35% nationwide.
United States waste management statistics from 2006 are presented in
BioCyle's 16th annual nationwide survey, "The State of Garbage in
America" (Vol. 47, No. 4, p. 26, April 2006). The article can

An historical perspective on the waste industry in the US, Canada,
and Europe is richly illustrated in “The
Future of Waste”,
(BioCycle, January 2004, pp. 59-62), by Helen Spiegelman and Bill Sheehan.
Sheehan
is cofounder and director of the Athens, Georgia-based Product Policy
Project (www.productpolicy.org)
and cofounder of the GrassRoots Recycling Network. Helen Spiegelman is
a cofounder of the Product Policy Project, and she is also a board member
of the Recycling Council of British Columbia and past president of the
Society Promoting Environmental Conservation, both in Vancouver. The

A valuable insight into sometimes opposing philosophies about waste
is offered by Guy Crittenden in his editorial entitled Zeroing
in on Waste printed in Solid Waste & Recycling magazine (June/July
2005). The specific philosophies Crittenden evaluates are "integrated
waste management (IWM)" and "extended producer responsibility
(EPR)".
