No Waste Technology
At the risk of keeping this discussion going for a little while longer, I will
note that DuPont has set a ZERO WASTE goal for its facilities (maybe they have
this on their web site). Incremental improvement will not get them there
quickly. GE has instituted a "six sigma program." They currently have about
35,000 defects per million (3 sigma). They are trying to go to 3.5 defects per
million (6 sigma) in 5 years (See Forbes, 1/26/98 p.44). I have spoken to some
of their environmental people who believe this program will be applied to wastes
as a defect. Xerox has a goal of zero waste factories (check out their website
at www.xerox.com). The paper industry has been looking at minimum effluent
mills (TAPPI Press, 1996). There is a great note on GREEN CHEMISTRY in C&EN
(ACS) in the December 22, 1997 issue (p.47). There are making things with
totally new pathways eliminating large amounts of waste along the way. Will
TetraTech or other large engineering firms be working on these projects if they
are so worried about the laws of thermodynamics? We need new technology in some
of these cases, totally new ways to make the things we want. Finding "safe"
substitutes will only get us new wastes. Why have large companies been flocking
in this direction and the P2 community is refusing to budge? By the way, we
have received some good examples along the way with this discussion. I am
surprised at the resistance to this concept by some members of the list.
