Administration
The Kalundborg center for industrial symbiosis was established and financed
by symbiosis partners with the following objectives:

• Follow-up on the current Kalundborg symbiosis.
• Developing a database for Kalundborg symbiosis and other successful
case studies.
• Developing an internal and external communication system to dis-
seminate information and experience.
• Coordinating studies on the industrial symbiosis according to demand
and need.
• Organizing of visits and study tours on the symbiosis.
• Consultation on new symbiosis projects.
• Contributing to forming new symbiosis projects.

Brownsville Eco-Industrial Park (Martin et al., 1996)
This case study is a prototype developed by a group of researchers for the
existing Brownsville eco-industrial park located in Texas, USA. The main
reason for selecting this case study in particular is that the group of
researchers who studied this EIP has developed five different scenarios based
on the level of interaction and the extent to which wastes and resources are
exchanged between members of the park. Not all of the EIP members par-
ticipate in each scenario. In scenario 1, very few of the companies are work-
ing together. As we move from one scenario to the next, the level of
cooperation and interactions among members of the park increases. In sce-
nario 5, each EIP member interacts with the others in some way. This means
that in one case study we will be able to trace the development of EIP and
how this will be reflected on the economical and environmental benefits.
To develop the EIP prototype and its different scenarios, the researchers
have collected data regarding the inputs and outputs of each company oper-
ating in the area of Brownsville, their willingness for using recycled material
