Which of the following should never be buried or incinerated?

Batteries should never be buried or incinerated due to their hazardous contents, which can include heavy metals and other toxic substances. When buried, batteries can leach harmful chemicals into the soil and groundwater, posing serious environmental risks. Incineration can release these toxins into the air, contributing to air pollution and potential health hazards for nearby populations. Proper disposal methods for batteries, such as taking them to designated recycling centers, are essential to mitigate these environmental and health issues.

In contrast, while options like plastics, food waste, and wood scraps have their own disposal guidelines, they do not carry the same immediate and severe environmental risks when disposed of improperly as batteries do.
