ST has established an integrated process for the environmental management of waste, covering compliancemonitoring of the quantity of waste produced each year, data collection and reporting. The Waste Ladder methodology, developed by ST, ensures an appropriate end-of-life treatment for each waste stream, based on its economic and ecological impacts. Very strict controls are maintained over the activities of the entire company. 

Waste from operations
Waste from operations is our most critical issue as it may contain hazardous materials. ST has set stringent targets to reduce waste generated from operations and to reuse or recycle materials. At ST dedicated areas have been built into all our manufacturing sites for waste collection, segregation and disposal. Each site ensures that waste is segregated and then managed as a distinct waste stream.
Hazardous materials
ST pays particular attention to hazardous waste resulting from production processes e.g. chemical substances, contaminated plastics and light-bulbs. Most hazardous waste is recycled or reused and the remaining waste is safely disposed of by specially-authorized companies.
External partners
ST’s waste management strategy extends to external partners. We conduct regular audits on waste storage, recycling, treatment and disposal of subcontracting and waste transport companies against ST requirements. 

Our performance and objectives are available in our latest Sustainability report.
