• La société Systèmes Durables offre un transfert de technologie et de compétences de la recherche vers les industriels, les collectivités, les chambres consulaires et les aménageurs de zones d’activités.

• Son expertise est axée autour de deux thématiques complémentaires :

LISST - CIEU

• Le Centre Interdisciplinaire d'Etudes Urbaines ( CIEU ) est une composante de l'UMR 5193, Laboratoire Interdisciplinaire Solidarités, Sociétés, Territoires (LISST) hébergé par l’université de Toulouse le Mirail.

• Thèmes de recherche :Axe 1 - Villes et systèmes urbains. Axe 2 - Ancrage territorial des systèmes économiques Axe 3 - Recomposition des territoires Axe 4 - Analyse des processus de différenciation et de ségrégations Axe 5 - Habiter dans la ville Axe 6 - Gouvernance et développement durable des villes

The biosphere-technosphere analogy

• Nature operates without any waste products. What is rejected by some organisms provides food for others.

• Processes for creating technomass are quite similar to processes for creating biomass

• Societal and technological systems can be viewed as particular ecosystem

Natural ecosystem

Artificial ecosystem

The industrial Ecology concept

"why would not our industrial system behave like an ecosystem, where the wastes of a species may be resource to another species?”

Frosch, R.A.; Gallopoulos, N.E. (1989) "Strategies for Manufacturing“ Scientific American

“The organisation of industry on this principle (…) means in effect using natural processes as a model, for in them the resolution of all

arising contradictions is the motive force of progress.”Davitaya, F. (1977) "Changes in the atmosphere and some problems of its protection“ Society and the Environment: A Soviet View; Progress Publishers.

From Industrial Ecology to territories

Geographical and territorial systems can be viewed as ecosystems

There is evident analogy between the functioning of natural ecosystems and the interactions between firms,

actors, territory portion, geographical area etc....

Towards territorial sustainability

• Considering territories as complex but coherent ecosystems in interaction with other natural and/or artificial ecosystems, industrial ecology :– provides new guidelines to break into the territories complexity– seeks global balance between territories and the biosphere– helps them to evolve towards sustainability

• Industrial Ecology applications have a large rangeSource: Chertow, 2000

Operating Industrial Ecology

• An important part of the emerging field of industrial ecology is the development of industrial symbiosis.

• Symbiosis means co-existence between diverse organisms in which each may benefit from the other.

• In the context of industrial ecology, the term is applied to the industrial co-operation between a number of companies and municipalities when they exploit each other’s residual or by-products or when they operate mutually.

Industrial Metabolism

• Metabolism is a term inherited from the study of living organisms.

• Industrial metabolism is nothing much than this principle applied to an artificial system

• A key tool to operate Industrial ecology as it helps to understand the physical flows that constitute the basis of the economy of a system (a territory for instance)

• It can reveal potential for new economic activities and / or industrial symbiosis development.

PRESTEO©

• A Client/server tool

• Allows to match industrial metabolism (from factories, industries, collectivities…)

• Helps to find eco-industrial symbiosis opportunities

New perspectives

• Understanding of the territorial systems and integrated approach of the territories is critical to enhance industrial ecology’s tools and methods.

• Thus, new researches involving “Systèmes Durables” and the “Université de Toulouse II – Le Mirail” started on April 2008.

• Their goal is to have a fresh look at the concept of territory from the angle of in order to reach an operational definition that resituates territory inside the biosphere’s bounds. This will also lead to a third version of the software PRESTEO.

• The cross-over between industrial ecology and social sciences such as spatial planning will create new knowledge and open innovative perspectives of research in both disciplines.
