for $20,000; and (4) the Midland Ross Extruder, available in 1980
and 1981 for $120,000. Grossman observed that all of these
machines were “widely available".
Grossman's opinion regarding the Sentinel EPE recycler was
based on the descriptions of such recycler as set forth in the
writings of other professionals. Grossman neither tested nor
examined the Sentinel EPE recycler.
Finally, Grossman reported on the relationship between the
plastics industry and the petrochemical industry. Grossman noted
that although the development of the petrochemical industry is a
contributing factor in the growth of the plastics industry, the
two industries have a “remarkable degree of independence".
Grossman observed that the “oil crisis" in 1973 triggered “dire"
predictions about the future of plastics that had not been
fulfilled in 1981. Grossman stated that the cost of a plastic
product depends, in large part, on technology and the price of
alternative materials. Grossman's studies concluded that a 300-
percent increase in oil prices results in a 30-40 percent
increase in the cost of plastic.
Grossman did not specifically value the Sentinel EPE
recycler. However, as previously stated, Grossman concluded that
existing technology was available that provided equivalent
capability of recycling polyethylene.
