Title: Cleaner Production, Industrial Ecology and Sustainability


1
Cleaner Production, Industrial Ecology and
Sustainability
  • Jouni Korhonen

2
Topics
  • Materials flows in industrial systems
  • Materials flows in ecosystems
  • Research challenges

3
Flows of Matter in Industrial Systems
Industrial system, production and consumption
  • Over-harvesting of renewables
  • Use of non-renewables

Nature
Nature
- Wastes exceeding the ecosystem carrying capacity
University of Tampere, Research Institute for
Social Sciences, Jouni Korhonen June 2005
4
Flows of Energy in Industrial Systems
Industrial system, production and consumption
  • Use of non-renewable fossil fuels

Nature
Nature
- Producing emissions exceeding natures
assimilation capacity
University of Tampere, Research Institute for
Social Sciences, Jouni Korhonen June 2005
5
Flows of Carbon in Industrial Systems
Industrial system, production and consumption
  • Use of geological carbon, extracted outside
    ecosystems

Nature
Nature
- Releasing cardon dioxide (CO2) foreign to nature

Natural Ecosystem A Sustainable System
Solar energy
Plants
Animals
Decomposers, scavengers, bacteria, fungi
Waste heat
Cyclical and cascading flow of materials and
energy based on infinite solar energy input
(master of recycling)

  • Research challenges
  • System Vs. System boundaries
  • Example Finnish forest industry imports and
    exports
  • System Vs. System component
  • Example Inter vs. Intra-organizational
    management
  • Eco-efficiency Vs. Growth
  • Example The rebound effect and the Jevons
    paradox, e.g. fuel efficient cars vs. mileage
    driven
  • Downstream impacts Vs. Upstream root causes
  • Example CFCs, SO2 as known impacts
  • Waste Vs. Its definition (cultural/social
    construct)
  • Examples Past vs. present, Developed vs.
    Developing countries
