Wastes that are household in origin, or that are generated in the food production, general building maintenance and office administration activities of those facilities to which this definition applies, are not considered to be biomedical or hospital waste but rather to be non-hazardous solid waste. Hazardous waste is defined fully in Appendix 5 of the Supplementary Guide. Hazardous waste incinerators must be licensed by the responsible jurisdiction. Hazardous waste incinerated in a mobile incinerator temporarily located at your facility must be included as part of this activity.

Sewage sludge means sludge from a facility treating wastewater from a sanitary sewer system.
