This document provides a timeline of industrial symbiosis from the 1800s to present day. It notes that in the 1800s, many industries would utilize waste from other industries as raw materials. The term "industrial symbiosis" was first coined in 1947 to describe relationships between dissimilar industries exchanging byproducts. Significant examples of industrial symbiosis developed between large industries located in Kalundborg, Denmark starting in 1959 and in Kwinana, Western Australia in the 1950s. The concept has since inspired eco-industrial parks and synergistic relationships between firms seeking economic and environmental benefits through industrial cooperation.
