How should I dispose of the Infinix X6512 Smart 6 HD and its battery at end of life?

The device, battery, and accessories must be disposed of in accordance with local regulations and must not be thrown away with normal household waste. The crossed-out wheeled bin symbol on the product indicates it must be taken to designated waste collection points using separate recycling services. Improper disposal can be harmful to human health and the environment. (Page 5)
