FIGURE 3.4 Scenario 1 – Baseline activities (Martin et al., 1996)

• The textiles company recycles cutting room clippings.
• The automobile parts manufacturer purchases a ringer system for
absorbent socks and rags.
• The seafood processor uses brown water for non-critical cleaning
processes.

Scenario 3
This scenario represents the first development stage of the EIP as shown in
Figure 3.5. This stage takes advantage of potential exchange opportunities
that can take place with little or no additional investment.

• The discrete parts manufacturer sells scrap plastic, which is currently
landfilled, to the recycler. He also purchases plastic pellets from the
plastic recycler instead of from a remote source. The benefits arise
from conducting both transactions with a local broker.
• The textile company sells plastic, which is currently landfilled, to the
plastic recycler.
• The auto parts manufacturer begins selling scrap plastic to the local
recycler, rather than the current recycler he uses in Chicago.
• The ballast manufacturer sells scrap asphalt to the asphalt company
for mixing with its virgin materials.
