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 either the Sentinel EPE
Recycler or the Sentinel EPS Recycler. However, as previously
stated, Grossman concluded that existing technology was available
that provided equivalent capability of recycling polyethylene and
polystyrene. Specifically regarding the Sentinel EPS recycler,
Grossman also concluded that recycling equipment that achieved
the same result as the Sentinel EPS recycler sold for about
$50,000 during the relevant period.
2. Lindstrom
Lindstrom graduated from Massachusetts Institute of
Technology with a bachelor's degree in chemical engineering.
From 1956 until 1989 Lindstrom worked for Arthur D. Little, Inc.
in the areas of process and product evaluation and improvement
and new product development, with special emphasis on plastics,
elastomers, and fibers. At the time of trial, Lindstrom
continued to pursue these areas as a consultant.
In his report, Lindstrom determined that several different
types of equipment capable of recycling expanded polyethylene
