recycling rate of

0 %

Because capacity demand increased, the total weight of waste produced in 2020 by WNC significantly increased compared to 2019. In order to continuously improve our waste recycling rate, waste recycling and reuse programs have been implemented. In 2020, the waste recycling rate exceeded 80% at all WNC sites, meeting our goal for the year.

Besides continuing to provide solder waste and PCB trim scraps to recycling vendors for metal recycling, WNC has also implemented several other recycling projects in 2020. Details on these projects are in the table below:

Management of Waste-cleanup Vendors

When cleaning up waste, WNC conducts waste sorting and reduction operations and has established qualified waste-storage areas. Waste is also handled by authorized waste-cleanup vendors. In accordance with regulations WNC files reports online on the waste it generates. WNC conducts annual inspections on its waste-cleanup vendors. The areas inspected include vehicles used for transporting waste, storage facilities, waste handling methods, document verification, and tracking the processing and transport of waste.
