Cleaner Production, Industrial Ecology and Sustainability Jouni Korhonen

Topics  Materials flows in industrial systems  Materials flows in ecosystems  Research challenges

Flows of Matter in Industrial Systems - Over-harvesting of renewables - Use of non- renewables Nature Industrial system, production and consumption Nature- Wastes exceeding the ecosystem carrying capacity University of Tampere, Research Institute for Social Sciences, Jouni Korhonen June 2005

Flows of Energy in Industrial Systems - Use of non-renewable fossil fuels Nature Industrial system, production and consumption Nature- Producing emissions exceeding nature’s assimilation capacity University of Tampere, Research Institute for Social Sciences, Jouni Korhonen June 2005

Flows of Carbon in Industrial Systems - Use of geological carbon, extracted ’outside’ ecosystems Nature Industrial system, production and consumption Nature - Releasing cardon dioxide (CO 2 ) foreign to nature University of Tampere, Research Institute for Social Sciences, Jouni Korhonen June 2005

Natural Ecosystem: A Sustainable System PlantsAnimals Decomposers, scavengers, bacteria, fungi Cyclical and cascading flow of materials and energy based on infinite solar energy input (’master of recycling’) University of Tampere, Research Institute for Social Sciences, Jouni Korhonen June 2005 Solar energy Waste heat

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 ’Jevon’s paradox’, e.g. fuel efficient cars vs. mileage driven  Downstream impacts Vs. Upstream root causes -Example: CFCs, SO 2 as known impacts  Waste Vs. Its definition (cultural/social construct) -Examples: Past vs. present, Developed vs. Developing countries University of Tampere, Research Institute for Social Sciences, Jouni Korhonen June 2005
