ENVIRONMENTAL REMEDIATION

Asbestos

Asbestos is a set of six naturally occurring silicate minerals with high insulation performance and therefore it has been widely used in the past for production of composite materials (roofing slabs, chimneys, pipelines) and insulation materials.

Fibers and asbestos dust, if inhaled, are carcinogenic. Italy has been the first European country to completely ban its use with law no. 257 of 12 March 1992..
