This project is providing benchmarking on UK industrial sectors and indicators on energy and resource productivity.

Stock dynamics and material flows

Durable materials and products remain in use, providing a service to the end user, for a number of years. The dynamics of product and material stocks can be used to estimate future material demand and material reaching the end of life. The uptake of new technologies (such as electric vehicles) are also influenced by stock dynamics. A modelling approach grounded in stock dynamics is being used to assess the interplay between a number of energy and resource demand reduction options, including: production efficiency, product lightweighting, reuse and recycling, material substitution, lifetime extension, product switching and changes to the service supplied.

What we are asking

  • How are energy and resource efficiency opportunities influenced by the in-use stock of materials and products?
  • What can the dynamics of product additions and removals from stock tell us about reuse opportunities?
  • How can service provision from durable materials be maintained under a low energy demand future?
