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 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
Industrial Symbiosis
5
Why Eco-Industrial Parks? EIPs are being promoted as one of the means of
achieving sustainable development:
Higher resource &
economic efficiency
Expanded use of
renewable energy
Community
Partnerships leading
to better economic
development &
quality of life
Ecological site
planning & green
buildings
6
From regional efficiency to a sustainable region
Regional efficiency
Regional learning
Sustainable Östergötland
7
Sustainable Regional Development
Metabolism
material and
energy
Social and
business
dynamics
Technical systems
and infrastructure
Governance and
institutions Sustainable
Regional
Development
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
9
Circularization of energy and material flows
Wastewater, liquid waste (Biogas production)
CO2, NOx, SOx
Organic portion (Biogas production)
CH4
(Upgrading)
Combustible portion (Electricity or
heating/cooling)
Organic Fertilizer (Urban agriculture)
Liquid fossil fuels
Food
Ashes from incineration (Construction material)
Construction materials
Gaseous fossil fuels
Used cooking oil (Biodiesel production)
Water Metals and other
minerals
