Okaz, 2 August 2026: The National Waste Management Centre released a guide defining eight main categories of waste and setting out technical mechanisms for classification, forming the basis of all waste management processes in the Kingdom.
The framework identifies municipal, industrial, construction and demolition, healthcare, marine, green, sludge, and special waste as the principal categories. Classification is based on source, physical and chemical properties, and hazard level.
The guide emphasises that classification underpins every stage of waste management, from determining whether a material qualifies as waste, to assessing whether it is hazardous or non‑hazardous, and finally selecting appropriate methods for transport, treatment, recycling, reuse, or disposal.
Waste producers are responsible for ensuring accurate classification, documenting data, and preparing reports. Service providers must verify the accuracy of accompanying data before handling waste. The Centre is empowered to check compliance, verify licences, conduct inspections, collect samples, and request records when necessary.
Hazardous waste classification involves a detailed technical process, including chemical characterisation, hazard assessment, and evaluation of properties such as toxicity, flammability, corrosiveness, and reactivity. These measures ensure that hazardous waste is subject to special handling, treatment, and disposal procedures to minimise risks to human health and the environment.
