FIGURE 3.8 The Bruce energy linkages (Cardina Group)

The positioning of and interaction occurring between these industries
enables the participants in the park to exchange recovered material so that
byproducts of one firm serve as a raw material in another. Any residues gen-
erated at the Bruce Agra Foods facility, for example, are used either for animal
feed or as an input for ethanol by Commercial Alcohols. Another established
waste linkage in the park involves the use of carbon dioxide from the fer-
mentation plant by Bruce Tropical Produce in their agricultural process.
Figure 3.8 illustrates the types of linkages that exist between the firms in
The Bruce Energy Centre. This project has been championed by Integrated
Energy Development Corporation, a local industrial firm. It has resulted in
substantial savings for the firms involved, an increase in local jobs, and envi-
ronmental benefits.

Fairfield Ecological Industrial Park, USA
The Fairfield park is located to the Southeast of Baltimore, Maryland, USA.
The park deals mainly with heavy Industries such as petroleum firms, chemi-
cal plants, trucking depots, asphalt manufacturing facilities, and others. During
the last couple of years a lot of effort has been put in by the City of Baltimore,
Baltimore Development Cooperation, and Cornwell University, for example,
to come up with an outline for an efficient ecological industrial park (Smart
Growth 2000).
