In October 2009, the public prosecutor of the Criminal Court of Alessandria (Italy) charged several individuals (including employees and former employees of Solvay and Ausimont SpA, now Solvay Specialty Polymers Italy - SSPI) in relation to alleged criminal violations of environmental laws and public health legislation. The provisional claims of civil parties admitted to the trial amounted to about €105 million.

In December 2015 the Assize Court of Alessandria sentenced three local Solvay/SSPI managers to imprisonment and awarded civil damages of around €400,000.

An appeal was lodged by all parties with the Assize Court of Appeal of Turin which rendered its decision in June 2018 confirming: 1) acquittal of two of the SSPI managers; 2) sentence of the three Solvay/SSPI managers reduced to a suspended sentence of 20 months imprisonment; 3) damages for civil parties were maintained at €400,000, but other civil claims were rejected; 4) the charge of sanitation failure was dropped; 5) SSPI not liable for damages to Alessandria Municipality. The term for lodging a further appeal before the Court of Cassation is still pending.

As of the end of 2016, seventeen civil proceedings were brought before the Civil Court of Livorno (Italy) by former workers and relatives of deceased workers at the Rosignano site seeking damages (provisionally quantified at €9 million) in relation to diseases allegedly caused by exposure to asbestos. Three of the seventeen proceedings have been dismissed so far.
