Re: friendly plastic?
I assume your "closed-loop system of fewer points with a reusable
stock-in-trade" was metal type? I think the points you raise about
energy loss, resources used, would apply to any manufacturing process.
In the 50s and 60s a great percentage of the manufacturing effort and
"stored energy" that went into metal type technology over the past
century was simply lost as materials, equipment, type, etc., were
scrapped and melted down. The same can be said about computer
technology and most any electronic technology where progress makes
obsolete with near lightening speed.
To answer Chris's question. Photopolymer waste is essentially carbon
in organic molecules. In terms of how does it effect the environment,
it meets EPA standards for disposal into the water system. Likely the
average homemaker dumps more hazardous stuff down the drain during the
daily cleaning process.
I have heard that some kind of polymer is actually pumped into old
sewer lines as it coats the walls of the pipes and prevents lead
contamination. A good portion of all living matter is polymer-based
(in the scientific sense). I could go on and on. Can you recycle
plates? I assume plastic-backed plates can be recycled as plastic?
since that is what they are. Maybe steel-backed plates could be
recycled as steel (I assume the polymer would burn off as carbon).
