Not knowing what Mike's definition of a "ruse" is, I can't refute his statement. I can shed some light on the matter. As usual, the situation is not so simple as the ideologues like to scream. Speaking as a chemical engineer who has worked for a variety of "evil" companies, I can tell you that most of the plastics industry is sincere about getting some kind of recycling going. This is not because of any altruism or new-found love of the environment. Rather, most these companies learned from the pollution laws of the 60's and 70's that one is far better implementing one's own programs than waiting for government (Federal and State) to ram them down your throat. Just by looking at the waste disposal numbers (the alarming rate at which plastic is consuming remaining landfill space), the industry has already resigned itself to that fact that recycling will become mandatory (maybe not this year, but within the 20 year life-time over which most chemical plants are designed to provide a good return on investment). Thus, five years ago an industry-wide effort was started to make recycling economically feasible (for the most part, it is not). Most plastic products are made from blends of various high purity feedstocks. The processing technologies are very sensitive to changes in purity and composition of these feedstocks. (before decrying this fact, remember: this property makes plastics valuable, since this means one has great control over the material properties with small changes the manufacturing process). This makes recycling post-consumer plastic waste extremely difficult to economically reprocess. Clearly, before recycling is economic, one must reduce the variance of the feedstock. The numbering system is a very cheap method that, when used industry-wide, goes long way towards cutting the variability. Notice, however, that this is but one step. As it is an easy one, the industry has already done this. The next steps are more difficult. In my few, the single biggest thing we can do as individuals to make plastics recycling a reality is to pressure our local governments into change the way solid waste disposal is financed. If everyone (business and residential) had to pay for their garbage pickup BY THE BARREL, than than throwing away plastic containers would have a marginal cost (under th current system, the marginal cost is zero: you pay the same for tossing 10 coke bottles as for one). This would greatly shift the economics in favor of recycling. At present, recycling must compete with (very cheap, very pure) virgin feedstocks. Tough. However, if trash cost by the barrel, than recycling must only be less expensive than disposal cost, which, in LA anyway, is much easier to achieve. Harassing companies is a poor way to move them: any company that does not watch it bottom line ceases to exist. However, shift the forces that affect the bottom line, and companies can be remarkably pliant. >Here's the new credo: you built it / manufacture it, it's yours for life. Whatever happened to personal responsibility? If you choose to buy something, why are you free of all moral taint while the manufacturer, which has devoted great effort to responding to the public taste, must bear all moral responsibilty? I have always thought that constructive effort was more useful for solving a problem than just trying to find someone else to blame. just my $0.02 worth - I look forward to the flames 8-) -- --------------------------------------------------------------------------- Tyler Holcomb * "Remember, one treats others with courtesy and repsect * tylerh@juliet * not because they are gentlemen or gentlewomen, but * caltech.edu * because you are." - paraphrased from Garth Henrichs *
