ST is committed to continuously reducing, re-using, recycling and managing waste streams from our 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.

"92% of ST's waste is recycled or re-used. 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, our EHS Decalogue requires that all sites meet either their national/local regulations or the company procedures whichever are the most rigorous. 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.
- Office and canteen waste
ST goes beyond EHS Decalogue targets to revalorize office and canteen waste. ST works closely with its canteen subcontractors to increase organic waste composting and the recycling of cardboard, bottles and cans. ST also recycles paper-based information via secure partners. Communication and events to raise employee awareness and engagement are also regularly organized.
- 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 regulations and ST standards.
Waste management objectives
- Reduce the generation of waste by at least 5% per year (kg per production unit)
- Reduce the generation of hazardous waste by at least 5% per year (kg per production unit)
- Re-use and recycle at least 95 % of waste
- Reduce landfill waste to less than 2%.
Our performance against these objectives is available in our Sustainability report.
