First, the wastes were separated in origin into hazardous
and non-hazardous. Non-hazardous were also separated into
recyclables, non-recyclables and domiciliary. The minimization
strategy was mainly focused on the periodical quality analysis
for preventing an early oil change in all the production equipments
and solvent dosage planning to avoid losses. In addition,
aqueous solvents, when possible, replaced chlorinated solvents.
The final destination of hazardous wastes was decided as follows:
treatment plants for immobilization and authorized landfill
and suppliers (paint, oil, grease and anti-stain packaging)
