Definitions “ Agricultural Waste” is any waste from a farm or market garden and includes organic matter such as manure from livestock, slurry, silage effluent and crop residues. It also includes packaging and film, and animal treatment dips. “ Animal Waste” includes carcases or parts of animals or fish, or products of animal origin not intended for direct human consumption, with the exception of animal excreta and catering waste. This includes wastes from the preparation and processing of meat, fish and other foods of animal origin. “Asbestos” includes materials containing a naturally occurring fibrous silicate mineral popular in manufacturing and industry due to its strength, chemical and thermal stability. All waste containing greater than 0.1% asbestos is classified as hazardous waste. Types of asbestos waste are: 

   

 

crocidolite (blue asbestos); actinolite; anthophyllite; chrysotile (white asbestos); amosite (brown asbestos); tremolite; products resulting from the primary crushing of asbestos ore.

“Batteries or Accumulators” are a source of electrical energy generated by direct conversion of chemical energy and consist of one or more primary (non-rechargeable) batteries or secondary (rechargeable) cells, as listed below: 





containing more than 0.0005 % of mercury by weight; containing: — more than 25 mg of mercury per cell, except alkaline manganese batteries, — more than 0.025 % of cadmium by weight, — more than 0.4 % of lead by weight. Alkaline manganese batteries containing more than 0.025 % of mercury.

Batteries contain heavy metals such mercury, lead, cadmium and nickel, which can contaminate the environment when improperly disposed of.

“ Biodegradable Waste” is waste that I s capable of undergoing anaerobic or aerobic decomposition, such as food or garden waste and paper and cardboard, i.e. waste that rots. “ Bottom Ash” is ash that collects at the bottom of a combustion chamber. “By-Products” are materials that are not one the intended products of a production process and include many wastes that are not spent materials or sludges. “ Cathode Ray Tubes” are vacuum tubes, made primarily of glass, which constitute the video display component of televisions and computer monitors. These tubes are classed hazardous due to their lead constituent. “ Cement Kiln Dust” is a fine dust generated during the cement production process. ‘Competent Agency’ where referenced, refers to the Presidency of Meteorology and Environment or its designated representative. “ Construction and Demolition Waste” arises from activities such as the construction of buildings and civil infrastructure, total or partial demolition of buildings and civil infrastructure, road planning and maintenance. It mostly includes brick, concrete, hardcore, subsoil and topsoil, but it can also include quantities of timber, metal, plastics and, occasionally, hazardous materials. “Corrosivity” is the property which identifies wastes that can readily corrode or dissolve flesh, metal or other materials. “ Dredged Spoils” consist of the sediments left over from dredging aggregates (hard rock, sand and gravel) from estuaries or coastal areas. “Electrical and Electronic Equipment” (“EEE”) means equipment which is dependent on electric currents or electromagnetic fields in order to work properly and equipment for the generation, transfer and measurement of currents and fields designed for use with a voltage rating not exceeding 1000 volts for alternating current and 1500 volts for direct current. “Fly Ash” refers to particles of ash, such as particulate matter which may also have metals attached to them, which are carried up the stack of a combustion unit with gases during combustion.

“ Mines and Quarry Waste” includes materials such as ‘overburden’, rock inter-bedded with the mineral, and residues left over from initial processing of the extracted material into saleable products. Extraction and processing waste may include: 



materials such as waste rock and sandy debris, fine grained materials (tailings), derived from crushing and washing the mineral.

These materials are non-hazardous and mostly chemically inert. They are often largely identical to the geological deposits in the locality from which they are extracted. “ Ozone Depleting Substances” (ODSs) are manmade chemicals used in a variety of applications such as refrigeration, fire fighting, foam blowing and as solvents and aerosol propellants.

Purpose a) The objective of this document is to establish a national baseline Waste Classification System within the Kingdom of Saudi Arabia. It is anticipated that this document will be employed nationally by all waste handlers to whom they apply with inspections taking place to verify their implementation progress at a regional level as outlined within the s tandards.

‘TSD Facility’ refers to a treatment, storage and/or disposal facility. “Tyres” are composed of vulcanised rubber in addition to the rubberised fabric with reinforcing textile cords, steel or fabric belts and steel-wire reinforcing beads. Waste tyres are those which have been permanently removed from vehicles without the possibility of being remounted for further road use.

b) The Standard for Waste Classification has effect for purposes connected with the regulation of waste and in particular for the purposes of providing: i)

A national classification system that may be employed within KSA by all waste generators, transporters, facility operators and the relevant competent agencies and other interested parties;

ii)

A classification, coding and defining of all waste types so they can be handled, treated or disposed of accordingly;

iii)

A classification methodology to ensure that waste is dealt with appropriately to ensure the protection of human health and the environment.

“ Used Oil Fuel” is any oil that has been refined from crude oil, or any synthetic oil, that has been used and, as a result of such use, is contaminated by physical or chemical impurities. “ Waste Electrical and Electronic Equipment” (“WEEE”) means electrical or electronic equipment which is waste within the meaning of including all components, subassemblies and consumables which are part of the product at the time of discarding. ‘waste handler’ is a generator, transporter and receiver of waste who has waste responsibilities. “ Waste Oils” are any mineral-based lubrication or industrial oils which have become unfit for the use for which they were originally intended, and in particular used combustion engine oils and gearbox oils, and also mineral lubricating oils, oils for turbines and hydraulic oils. (see also Used Oil Fuel). ‘waste tracking’ is the recording of information from the waste generator about the quantity and type of waste produced; recording information about who transported the waste and when; recording information from the waste receiver about the quantity and type of waste received; and matching information about the waste from both the generator and the receiver.

Hazardous Waste a) Hazardous waste is waste which presents a hazard to human health or the environment because it contains dangerous substances. A waste is hazardous if; i)

3)

it is included in the Hazardous Waste List, Appendix A, Table 1; and/or

ii)

it contains one of the hazardous constituents listed in Appendix B, Table 2; and/or

iii)

it displays one of the hazardous properties listed in Appendix C, Table 3, for example, toxic, corrosive or dangerous to the environment; and/or

Classific ation of hazardous waste a) To establish whether a waste is classified as hazardous, it must be determined if the waste is Listed on the Hazardous Waste List (Appendix A, Table 1). b) If a waste is identified as one of the waste streams in the Hazardous Waste List then it must be classified and treated as hazardous, irrespective of whether a hazardous waste constituent or property is present or not in the waste. The Table lists wastes from generic industrial processes, wastes from certain sectors of industry and unused pure chemical products and formulations. Any waste fitting a narrative listing description is considered a listed hazardous waste. c) If the waste is not listed, a waste Generator must then establish whether the waste contains any of the hazardous constituents listed in Appendix B, Table 2. These constituents pose a threat to human health and the environment. d) If the waste is not listed in the Hazardous Waste List or does not contain one of the hazardous waste constituents, the assessor of the waste must determine the waste’s composition to establish whether it contains a hazardous property, as listed in Appendix C, Table 3, according to either: i)

liquid wastes (other than those aqueous waste containing less than 24% alcohol by volume) that have a flash point less than 60°C (140°F). The flash point test determines the lowest temperature at which the fumes above a waste will ignite when exposed to flame; solid wastes that, under standard temperature and pressure, are capable of causing fire through friction, absorption of moisture, or spontaneous chemical changes and, when ignited, burn so vigorously and persistently that they create a hazard.

4)

Potentially explosive; Reacts violently; or Generates toxic gases or vapours.

iii)

If a cyanide or sulfide-bearing waste is exposed to pH conditions between 2 and 12.5, it can generate enough toxic gases, vapours, or fumes to present a danger to human health or the environment.

i)

It is normally unstable and readily undergoes violent change without detonating or becomes unstable if resulting from decomposition from shock or impact.

Ignitability a) Wastes that display the ignitability property are those that can readily catch fire and sustain combustion. Wastes that are hazardous because they may ignite include the following:

At standard temperature and pressure; If subjected to a strong ignition source; or If heated under confinement.

When mixed with water, it is: -

Toxicity a) Toxic compounds or elements can leach into underground drinking water supplies and expose users of the water to hazardous chemicals and constituents. A waste is toxic if it is likely to leach dangerous concentrations of toxic chemicals into groundwater. The Toxicity Property Leaching Procedure (TPLP) requires that a liquid leachate is created from a hazardous waste sample. It must then be determined whether the leachate contains any of the toxic chemicals in amounts above the specified levels listed in Appendix D, Table 4.

Corrosivity a) Corrosive wastes can readily corrode or dissolve flesh, metal or other materials. Corrosive hazardous wastes include the following; i)

aqueous wastes with a pH of 2 units or below or of 12.5 units or above; and

ii)

liquid wastes that corrode steel at a rate greater than 6.35 mm (0.250 inches) per year.
