Industrial ecology

The science of industrial ecology emerged in the late 1980's and refers to the study of the physical, chemical and biological interactions and interrelationships within and among industrial and ecological systems. Applications of industrial ecology involve identifying and implementing strategies for industrial systems to more closely emulate harmonious and sustainable ecological systems. Industrial ecology can be considered a comprehensive approach to implementing sustainable, industrial behaviour; it is the shifting of industrial process from linear (open loop) systems, in which resource and capital investments move through the system to become waste, to a closed loop system where wastes become inputs for new processes.
 
Industrial ecology was popularised in 1989 in a Scientific American article by Robert Frosch and Nicholas E Gallopoulos. Frosch and Gallopoulos' vision was "why would our industrial system not behave like an ecosystem, where the wastes of a species may be resource to another species? Why would not the outputs of an industry be the inputs of another, thus reducing use of raw materials, pollution, and saving on waste treatment?"
 
Industrial ecology proposes not to see industrial systems (for example a factory, an ecoregion, or national or global economy) as being separate from the biosphere, but to consider it as a particular case of an ecosystem - but based on infrastructural capital rather than on natural capital. It is the idea that if natural systems do not have waste in them, we should model our systems after natural ones if we want them to be sustainable.
 
Industrial ecology is practiced throughout the concrete supply chain.
