This document summarizes a presentation by Phil Johnson from International Synergies Limited on industrial symbiosis and the circular economy. It discusses International Synergies as a company, defines industrial symbiosis, presents case study examples, and outlines their model for delivering industrial symbiosis programs. Key points include that industrial symbiosis connects unused resources from one company to another for mutual economic and environmental benefit, and that their National Industrial Symbiosis Program in the UK has delivered substantial cost savings, material reductions, jobs created and carbon reductions.
