Technical Guidelines Biological Waste Treatment

1.1        Purpose

This Technical Guideline (TG) sets out the information that will be used by the National Centre for Waste Management (the Centre) to regulate and licence biological waste treatment facilities in the Kingdom of Saudi Arabia (KSA).

Therefore, this document is intended to provide a guideline for those involved in design, construction, and operation of biological waste treatment facilities, to:

• Identify and determine all requirements for developing different biological waste treatment facilities according to the international best practices and latest available technologies;

• Provide practice guidance on how to treat biodegradable waste through different biological waste treatment technologies in an environmentally-sound manner;

• Identify the key technical and management parameters that influence the performance of the facility, minimise potential environmental impacts as well as health and safety risks for worker and the general public.

This technical guideline is not a design manual or a standard for biological waste treatment facilities. Sound judgement and the appropriate technical expertise needs to be applied to ensure that, when designed, constructed, and operated, biological waste treatment facilities will comply with the principles set out in this TG as well as with any conditions of a licence issued by the Centre.

1.2        Scope

The provisions of the present Technical Guideline address all parties involved in the management of biological waste treatment facilities, namely:

• The National Centre for Waste Management (MWAN or the Centre);

• The Environmental Protection Competent Authorities or The National Centre of Environmental Compliance (NCEC);

• Design and Construction companies involved in biological waste treatment facility projects; and

• Biological waste treatment facility operators (Service Providers).

It covers aerobic and anaerobic digestion of non-hazardous organic fraction from municipal solid waste (MSW) streams (including residential waste, institutional and commercial waste), industrial waste streams, green waste, and agricultural waste.  

This document does not address or apply to the biological treatment of water-based liquid waste.
