Industrial symbiosis (IS) / synergies
What does the modern industrial process look
like?
Eg – making beer
-to produce beer, it uses energy and resources
while producing waste energy and by products
-it is a linear process within a firm
-we can apply and environmental management
systems(EMS) to reduce the environmental
impacts
Eg – traditional product life cycle
-many firms work together to produce a
product, it uses energy and resources while
producing waste energy and by-products
-it is a linear process that happens between
firms
What does symbiosis?
-any interdependent or mutually beneficial
relationship between two persons/group
What can we apply to reduce the environmental
impacts between firms?
Synergy- an exchange of waste (in excess)
resources and energy between companies for
mutual benefit
Benefits:
-economic benefit – cost saving and higher
efficiency
-environmental benefit – less “wasted”
materials and energy
-economic/environmental – increase resource
efficiency (eco-efficiency) and security
-social- employment opportunities
Industrial symbiosis
-is the capture, recovery and reuse of previously
discarded or unrequired resources from one
industrial operation by other, traditionally
separated, industries operating near by
Characteristic
-engages traditionally separated industries in a
collective approach to competitive advantage
involving physical exchange of materials,
energy,water and/or by products
FOUR types of IS
1.by products- one company uses the waste of
another company
2.utility synergies-companies have joint
infrastructure and use waste/energy from each
other
3.service synergies-sharing service and
facilities like transport, security.
4.supply chain synergies- when companies use
similar input/output so they can save on
distribution of inout/output
Planning map for industrial symbiosis
-inorganic by products –
-water –
Energy –
3 stages of IS toolkit
1.assess potential for synergies in an industrial
area
2.deliver detailed listing of possible synergies
3.priotise identified synergies
Problems in Australia for by product reuse
-no standard requirements of reuse for many
applications eg soil conditioning or for use as a
road base, fill material
-lack of leadership and support from
government when dealing with related
community issues and concerns
-by-products continue to build up in storage
facilities
International regulatory frameworks and
standards
In USA and EU - regulatory frameworks and
standards are widely used
-EU alternative materials framework carried
out to remove the uncertainties associated with
using alternative materials
Identifying drivers and barriers to symbiosis
development
1.regulation
D: air, water quality requirements, reporting
schemes
B: complicated, approval procedures
2.economics
D: increased revenue
B:low cost of resources and waste disposal

Document Summary
To produce beer, it uses energy and resources while producing waste energy and by products. It is a linear process within a firm. We can apply and environmental management systems(ems) to reduce the environmental impacts. Many firms work together to produce a product, it uses energy and resources while producing waste energy and by-products. It is a linear process that happens between firms. Any interdependent or mutually beneficial relationship between two persons/group. Synergy- an exchange of waste (in excess) resources and energy between companies for mutual benefit. Economic benefit cost saving and higher efficiency. Economic/environmental increase resource efficiency (eco-efficiency) and security. Is the capture, recovery and reuse of previously discarded or unrequired resources from one industrial operation by other, traditionally separated, industries operating near by. Engages traditionally separated industries in a collective approach to competitive advantage involving physical exchange of materials, energy,water and/or by products less wasted service and synergies-sharing synergies-companies have.
