WEEE Notice¶

The European Directive on Waste Electrical and Electronic Equipment (WEEE), which became effective on February 13, 2003, has led to major changes regarding the reuse and recycling of electrical equipment.

The main objective of this directive is to prevent waste from electrical and electronic equipment and to promote reuse, recycling and other forms of recovery. The WEEE logo on the product or packaging indicates that the product must not be disposed of with other household waste. You are responsible for disposing of all discarded electrical and electronic equipment at appropriate collection points. Separate collection and sensible recycling of your electronic waste helps to use natural resources more sparingly. In addition, proper recycling of waste electrical and electronic equipment ensures human health and environmental protection.

For more information on disposal, recycling, and collection points for waste electrical and electronic equipment, contact your local municipal authority, waste disposal companies, the distributor, or the manufacturer of the equipment.
