Hazardous waste recycling standards for other hazardous wastes are found in ch. Wis. Adm. Codes. Wisconsin's rules exempt from licensing certain hazardous waste recycling activities. The rules also include specific requirements for each type of recycling activity to ensure that public health and the environment are adequately protected. Basically, recycling of hazardous wastes means the beneficial use, reuse, or legitimate recovery or reclamation of a hazardous waste.
Recycling also includes the recovery of energy from hazardous wastes.
In order to come under the recycling exemption, the activity must be a legitimate form of recycling. The recovery or reclamation of hazardous waste means removing contaminants so that the waste can be put to further use, processed to recover usable materials, or returned to its original form. Examples include distillation of spent hazardous solvents and the recovery of the silver from photographic waste. S. NR 625.06 Wis. Adm. Code. A written approval is not required.
