WASTE CATEGORIES

The proposed Waste Management Activity is classified as a Waste Recycling and Recovery process using Pyrolysis based Thermal Treatment in line with the Waste Management Hierarchy and the requirements of the various Policies on Thermal Treatment of Waste - including Pyrolysis as a Complimentary Waste Management option. This Waste Management Activity is further defined as a Waste Minimisation Programme and creates high quality Refuse Derived Fuels. 

The following Waste Categories were considered from a feedstock or pre treatment point of view as well as a post treatment point of view.

Category A: “Hazardous Waste” 

Means any waste that contains organic or inorganic elements or compounds that may, owing to the inherent physical, chemical or toxicological characteristics of that waste, have a detrimental impact on health and the environment and includes hazardous substances, materials or objects within business waste or residue deposits as outlined below:

HAZARDOUS BUSINESS WASTE 

(4) Waste from Petroleum Refining and Natural Gas Purification 

(6) Waste from Organic Chemical Process: (b) MFSU of Plastics, Synthetic Rubber, Manmade Fibres; (e) Pharmaceuticals

(12) Oil Waste and Liquid Fuels: (d) Oil/Water separator waste; (e) Waste of Liquid Fuels;

(14) Other not specified: (c) Unused and off-spec batches; (f) waste from barrel cleaning, tank cleaning;

(17) Waste from Waste Treatment Facilities: (a) incineration or pyrolysis waste; (g) Metal containing shredded waste; (h) Waste from oil re-generation;

      

Category B: “General Waste”

Means waste that does not pose an immediate hazard or threat to health or to the environment, and includes—

(a) domestic waste;

(b) building and demolition waste;

(c) business waste;

(d) inert waste; or

(e) any waste classified as non-hazardous waste in terms of the regulations made under section 69 of NEM:WA, and includes non-hazardous substances, materials or objects within business, domestic, inert, building and demolition wastes as outlined below:

       

Category B: "Business Waste"

(4) Waste from Thermal Processes: (a) Waste from other combustion plants and power stations

(7) Oil Waste and Liquid fuels: (a) Oil Waste

(8) Other Waste not Specified: (a) End-of-life vehicle and machinery; (b) Electronic; (c) Unused and off-spec batches;

(10) Waste from Waste Treatment Facilities: (a) incineration or pyrolysis waste; (d) Metal containing shredded waste; (e) Waste from mechanically treated waste (sorting, crushing, shredding, pelletizing)

Excluded Waste Streams

The following waste is excluded from any process of GTEK, any waste that consists of or includes:

  • Anatomical, infectious or biologically active medical/health care waste;
  • Asbestos containing waste;
  • Bio-hazardous waste;
  • Entire batteries;
  • Explosives;
  • Mineral acids and corrosives;
  • Radioactive waste;
  • Any POP containing waste;
  • Unsorted municipal waste; and
  • Unknown or unidentified wastes.

Waste Regulations

The regulatory framework varies from country to country and within regions of countries. GrahamTek has evaluated some of the more sensitive regulations and designed its standard Equipment Set to meet the more stringent regulations. For larger scale operations a full Environmental Assessment study would typically be required. GrahamTek uses Worley Parsons, a global partner, as its Environmental Assessment Consultants. The list below provides the context to a basic EIA for the standard plant design. 

  • GNR 921: s3(2) CATEGORY A - BASIC ASSESSMENT - “The sorting, shredding, grinding, crushing, screening or bailing of general waste at a facility that has an operational area in excess of 1000m2.”
  • GNR 921: s3(3) CATEGORY A - BASIC ASSESSMENT - “The recycling of general waste at a facility that has an operational area in excess of 500m2, excluding recycling that takes place as an integral part of an internal manufacturing process within the same premises.”
  • GNR 921: s3(4) CATEGORY A - BASIC ASSESSMENT - “The recycling of hazardous waste in excess of 500kg but less than 1 ton per day calculated as a monthly average, excluding recycling that takes place as an integral part of an internal manufacturing process within the same premises.”
  • GNR 921: s3(5) CATEGORY A - BASIC ASSESSMENT - “The recovery of waste including the refining, utilisation, or co- processing of waste in excess of 10 tons but less than 100 tons of general waste per day or in excess of 500kg but less than 1 ton of hazardous waste per day, excluding recovery that takes place as an integral part of an internal manufacturing process within the same premises.” 
  • GNR 921: s3(6) CATEGORY A - BASIC ASSESSMENT - “The treatment of general waste using any form of treatment at a facility that has the capacity to process in excess of 10 tons but less than 100 tons.”
  • GNR 921: s3(7) CATEGORY A - BASIC ASSESSMENT - “The treatment of hazardous waste using any form of treatment at a facility that has the capacity to process in excess of 500kg but less than 1 ton per day excluding the treatment of effluent, wastewater or sewage.”
