Environment: Reduction of the use of (raw) materials

The downloadable document describes two strategies for reducing the use of (raw) materials in order to cause less harm for the environment. The first strategy is called: 'Choice and saving of (raw) materials' and the second strategy is called: 'Closing the material-cycle'.
Both strategies are here explained with checklists. These checklists have proved to be very helpful in identifying opportunities for reducing the use of (raw) materials and achieving cost savings in the process.
