The most costly aspect of hazardous materials handling is disposal. There are many regulations that can affect the disposal of used Exsorbet.
Regulations differ from state to state, county to county and landfill owner to landfill owner.
In time, most states will have the same regulation. Some states also regulate the parts per million of contamination in the used absorbents. Generators of the waste need to determine if their waste stream is hazardous or non-hazardous. The ten pound rule is intended to help regulate the small generators. Most large factories will not fall under the ten pound rule and will conform with some type of pre-determined disposal program.
