Scheduled Waste Management

Scheduled waste is any wastes that possess hazardous characteristics and have the potential to adversely affect the public health and environment. There are 77 types of scheduled wastes listed under the First Schedule of Environmental Quality (Scheduled Wastes) Regulations 2005 and the management of wastes shall be following the provisions of the above Regulations.

Waste can be classified by obtaining information on how the waste is generated and the raw materials used in the related process. By identifying the source of the waste and/or its specific hazardous characteristics, the waste generator can use the information to classify the waste and the specific SW code by referring it to the list of scheduled wastes in the First Schedule of the Regulations of the Environmental Quality (Scheduled Wastes) Regulations 2005.
