ST is committed to continuously reducing, re-using, recycling and managing waste streams from manufacturing sites including hazardous substances, metals, packing, plastics and other non-biodegradable materials.
Waste management is a strategic environmental focus for every ST site. ST’s waste strategy covers all waste streams, from operations sites and products. Our Environment Health and Safety (EHS) Decalogue contains ambitious targets to increase re-use and recycling ratios and also to identify the most appropriate solutions for waste disposal to avoid sending waste to landfill.

"ST continuously strives to reduce the amount of waste it generates and to identify the most appropriate disposal solution based on environmental and economic impacts".
ST has established an integrated process for the environmental management of waste, covering compliance, monitoring 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.
ST's operational waste
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 re-use or recycle materials. At ST, even though waste is managed according to country prerequisites and local requirements. 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 re-used and the remaining waste is safely disposed of by specially-authorized companies. In accordance with the Basel Convention, none of our sites export hazardous waste.
- External partners’ waste
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.
