Industrial symbiosis engages traditionally separate industries in a collective approach to competitive advantage involving physical exchange of materials, energy, water, and/or by-products (Chertow, 2000). Industrial symbiosis often deals with the use of a previously disposed waste (as solid, liquid, gas) from one facility by another facility to provide a valuable by-product.

The identification of industrial symbiosis opportunities is often done through rigorous assessments, including the analysis of industry inputs/outputs, discussions with park management and companies, opportunity identification workshops, and desktop review of international experiences.
