7. Recycling of Discarded Goods

Improper disposal of product waste may harm personal safety or damage the natural environment. It is recommended that consumers comply with local safety and environmental regulations and hand over the product to a local distributor or qualified waste recycling department for disposal when it is abandoned, in order to avoid environmental pollution and improve the material recycling rate.
