Materials and products

Different materials

It is possible to make a product from different materials, for example. A window frame, for example can be made from wood or uPVC. The life cycle assessment for a product will depend on the material that it is made from.

Different products

It is possible to use the same material to make different products. Polythene can be used to make food wrap (cling film) or a bucket, for example. The life cycle assessment of different products will be different, even though they are made from the same material.

A life cycle assessment can be used to compare and evaluate the impact of:

  • the use of different materials for the same job
  • the use of the same material for different jobs.
