Quantifying your resources is important to later deciding where your business has an opportunity for industrial symbiosis: small quantities, or resources used infrequently, may not present very good opportunities, whereas large quantities used on a regular basis may. Resources that are expensive, or hard to source, may also be priorities to consider.
Measurement is an important part of data collection and will help you prioritise where industrial symbiosis could make a significant difference to your business. Measures should be simple, related to cost and quantity, timely and accurate. The more accurate your measurements are, the better they reflect your business processes and the opportunities available through industrial symbiosis.
