Our total waste generation includes regular ongoing waste generated by our manufacturing sites (including manufacturing, office and cafeteria waste), as well as one-time waste. We consider one-time waste to be those waste streams that are not generated as part of normal operations, but rather by unique, one-time projects. One-time waste accounted for less than 1% of total waste generation in 2022, and is not included in our normal waste metrics and analysis unless otherwise indicated.
In 2022, our production increased and, as a result, we generated more waste. However, our efforts to reduce, reuse and recycle the waste produced by our manufacturing processes improved our overall waste performance.
We have waste-reduction programs in place at our sites to handle and manage hazardous and non-hazardous waste in an environmentally responsible manner.
For any waste that requires special handling, we ship it to vendors equipped with the knowledge and expertise to properly reclaim, recycle or destroy it. All our waste handling is done according to local rules and regulations.
We regularly audit our waste-management vendors to confirm they are meeting compliance requirements, handling waste responsibly and managing disposal with minimal impact to the environment.
In 2022, we recycled 83% of our total waste (hazardous and non-hazardous), an increase of 10 percentage points compared to 2021. Our recycling rate reflects waste-to-energy activities, which include the conversion of non-recyclable waste materials into usable heat, electricity or fuel through incineration. If we exclude waste-to-energy, the 2022 recycle rate is 78%.
Our E-Scrap Program ships scrap waste to processing plants that reclaim and recover these valuable (and potentially toxic) metals to reduce the amount of e-waste sent to landfills.
In 2022, although production increased 9% compared to 2021, our e-scrap went down, mainly due to process-yield improvements implemented during the year.
