How should I dispose of the Infinix X6515 Smart 7 at the end of its life?

The device, battery, and accessories must not be disposed of with normal household waste. They must be taken to designated waste collection points and recycled using separate recycling services in accordance with local laws, as indicated by the crossed-out wheeled bin symbol on the product. Improper disposal may be harmful to human health and the environment. (Page 6)
