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

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
