  • Treated wood: Wood that contains chemical preservatives including creosote, copper chromium arsenic or other arsenical preservatives, pentachlorophenol, etc.

Disposition Methods

Stabilization:
Treatment where waste is chemically stabilized into a solid or semi-solid state such that it no longer exhibits hazardous characteristics and can be managed as non-hazardous waste (does not apply if after stabilization, waste is still hazardous and is sent for disposal or treatment by one of the other methods described here).
Neutralization/Treatment:
Treatment by chemically adjusting the pH of the waste such that the waste can be discharged into a publicly owned treatment works (does not apply if after neutralization, the waste is still hazardous and is sent for disposal or treatment by one of the other methods).
Reused:
Waste is used without further treatment or handling for the original intended purpose of the material before it became a waste.
Landfill:
Disposal of a waste in the ground at a hazardous waste landfill.
Fuel incineration:
Treatment by thermal destruction where the waste, either by itself or blended with another material, is burned to recover its potential thermal energy.
Destructive incineration:
Treatment by thermal destruction at a high temperature hazardous waste incinerator where the physical destruction is the sole intent of the treatment process.
Steward:
A product stewardship organization that meets the mandatory "Extended Producer Responsibility" (EPR) requirements of product stewardship. These include, at a minimum, the requirement that the producer's responsibility for their product extends to post-consumer management of that products and its packaging. There are two related features of EPR policy: (1) shifting financial and management responsibility, with government oversight, upstream to the producer and a way from the public sector; and
Recycled:
Waste is sent for resource recovery where the raw materials used for making the material before it became a waste are recovered to make new materials of the same or different nature (does not include fuel incineration).
