On Li-on batteries:

The U.S. Environmental Protection Agency (EPA) does not regulate the disposal of batteries in small quantities; large quantities are regulated under the Universal rules of Hazardous Waste regulations (40 CFR PART 273). Lithium batteries are not currently being collected by manufacturers for recycling. Lithium batteries are currently disposed of after their use.
...
Incineration must be performed by an approved and permitted waste treatment facility that handles lithium ion batteries. If you are not sure if your waste facility can handle lithium ion batteries, contact them and verify if they are permitted or not.
