Semiconductor manufacturing is necessarily resource-intensive, and SilTerra has implemented thorough waste management procedures that cover wastewater, air emissions and scheduled (toxic) waste. In line with its Hazardous Substance Process Management Policy, SilTerra takes measures to minimise risks related to hazardous substances in its products. Products are regularly sent to accredited laboratories for independent analysis, enabling swift detection in the event that these products exceed the hazardous substance concentration limits as stated in the Directive 2002/95/EC on the restriction of the use of certain hazardous substances in electrical and electronic equipment (“RoHS Directive”) and Regulation 1907/2006/EC concerning the registration, evaluation, authorisation and restriction of chemicals (“REACH”). Close collaboration is also maintained with material suppliers to ensure that procured materials do not exceed the same concentration limits. These stringent practices have contributed to SilTerra’s certification with IECQ QC 080000 (Certificate of Conformity for Hazardous Substance Process Management). Lastly, SilTerra strives to minimise waste-to-landfill by recycling certain waste categories – such as paper, cardboard, packing materials and metal parts – and utilising electronic processes and platforms to replace printed documents.
