Measuring environmental impact

The environmental cost indicator (ECI) was created in response to the increasing demand for sustainability. This expresses the environmental impact of a product in euros.

To calculate the MKI, the environmental impact at each stage of a product's life cycle is first calculated by performing a life cycle assessment (LCA).

The results from the LCA are then linked to monetary weighting (€) and added together to arrive at 1 MKI score.

LCA (Life Cycle Assessment of greenSand

An extensive life cycle analysis has been made by Nibe for greenSand Semi-hardening and for greenSand Brekerzand, in which the following components have been taken into account:

• the mining process, the crushing, the transport to the Netherlands (A1 to A3)
• transport to customer in the Netherlands (A4)
• applying the material (A5)
• use (B)
• reuse (C)

These have been validated by LBP Sights. The shortened versions of the LCA can be found on the product pages.
