In this episode, Elaine Kerr, Deputy Director of International Synergies Northern Ireland, talks to Catherine Weetman about industrial symbiosis and how it ‘oils the wheels’ of the circular economy.
Elaine explains what industrial symbiosis is, and how International Synergies provides research and facilitation for ‘resource matching’, helping organisations of all types and sizes.
We discuss the multiple benefits of industrial symbiosis: reducing waste and pollution (and associated costs); creating valuable new by-products, jobs and social value; together with securing access to future resources by setting up local ‘ecosystems’ for materials.





























Elaine tells us how creating new, local feedstocks from redundant resources can also bring widespread benefits for the local economy, by helping improve economic prosperity and resilience.
We talk about changing attitudes and the ways young entrepreneurs and social enterprises are creating value from what we used to think of as ‘waste’.
















Read on for a summary of the podcast and links to the people, organisations and other resources we mention.

What is Industrial Symbiosis?
Symbiosis, the Greek word for ‘living together’, is any relationship between different things, people, or groups that benefits all those involved.  An example from nature is between trees and fungi, which help provide nutrients to each other. 
Industrial symbioses are an important part of the circular economy, using the principle of waste = food.  In other words, using the waste from one organisation to replace virgin resources for another, at the same localising supply and reducing costs.
One of the most famous and large-scale examples is the Kalundborg Symbiosis project, in Denmark.  It started in 1972, and there are now nine industrial partners exchanging a wide range of materials and resources.  There are videos and an interactive map on the
