Company I worked for used recycle polymer in two of their most

not have to be clear. They did not brag about being environmentally

I think it was '71, sometime during the oil embargo, when I was at the
NPE in Chicago and material of any type was hard to come by. I remember
talking to one guy who had to take two carloads of styrene toilet seats
for regrind to get one of virgin styrene. We sold thermoset molding
systems so regrind wasn't an option. There was a lot creativity with
replacing compounds with stuff derived from furfural. The stuff flowed
like water and the moldmakers had fits adapting to it.
