The document summarizes an upcoming conference on industrial ecology and symbiosis taking place from October 13-14, 2011 in Norrköping, Sweden. The conference will discuss how industrial ecology aims to optimize energy and resource consumption by having the waste of one process serve as the input for another in an interconnected system. Industrial symbiosis is seen as a process where materials, energy, and information flows are investigated between companies to develop cooperative links and improve efficiency. The conference aims to explore how cities and industry can work together in a sustainable way through approaches like industrial ecology that treat the urban environment holistically by closing material and energy loops.

2. Industrial Ecology definition
Industrial ecology is described as:
An integrated system, in which the
consumption of energy and materials is
optimised and the effluents of one process
serve as the raw material(s) or energy for
another process
(Frosch & Gallopoulos, Scientific American:1989)

3. Industrial Ecology: Interconnectedness of
Physical & Social Systems
Physical Systems:
Technology, Material and Energy Flows
interconnectedness
Social Systems:
Individuals, Organisations, Culture,
Values, Institutions

4. Industrial Symbiosis
Industrial Symbiosis is seen as a
process whereby materials, water,
energy in the techno-sphere and
informational, organizational and
management flows at the institutional
level between and among companies
are investigated with the objective of
developing and improving co-
operative links between/among them

5. Why Eco-Industrial Parks?
EIPs are being promoted as one of the means of
achieving sustainable development:
Community
Partnerships leading
to better economic
development &
quality of life
Higher resource &
economic efficiency
Ecological site
planning & green
buildings
Expanded use of
renewable energy

8. Through an industrial ecology approach…
•The urban environment is treated as an interconnected
system, not isolated subsystems
• Linear behaviours are transformed into circular ones
• Energy and material waste is minimized
• New links between different sectors are established
• Products/materials are converted to another use when
their initial use is completed
