1.2 Purpose of this waste assessment - Waikato District Council

“…material that when discharged to the environment will have no adverse effect on people or the environment. Thisincludes natural materials such as clay, soil and rock, and other inert materials such as broken concrete and brick, ormixtures of any of the above, and excludes:(a) material that has combustible, putrescible or degradable components, and(b) materials likely to create leachate by biological or chemical breakdown, and(c) products or materials derived from hazardous waste treatment, hazardous waste stabilisation or hazardouswaste disposal practices, and(d) materials such as medical and veterinary waste, asbestos, or radioactive substances that may present a risk tohuman health, and(e) materials contaminated with hazardous substances or pathogens, and(f) hazardous substances.This definition is very similar to, but not exactly the same as, the Cleanfill Guidelines definition quoted above(for example liquid waste is not mentioned).For some types of waste, cleanfills are competing directly with landfills. However, cleanfills are much less costlythan landfills to establish and require much lower levels of engineering investment to prevent discharges intothe environment. Cleanfills also have much lower compliance costs than landfills. Because of these differingcost structures, cleanfills charge markedly less for disposal than landfills, often on the order of 10 per cent oflandfills’ gate charges.There are several consented cleanfill operations in the Waikato district.Table 2: Cleanfill facilitiesName/operatorBombayQuarry,HolcimKey services/waste streams Location Capacity & estimatedoperational lifeCleanfill disposal, for quarry customers onlyRidge Road,BombayUp to 500,000 m3 from late2011, consented to 2025PerryResourcesLtdCleanfill disposal for public (topsoil, clay,spoil); $5 plus GST per tonne, if takingsand $4.50 plus GST, topsoil is free (laterscreened and sold)HutchinsonRd, HorotiuConsented to 2030Wedding IH& Sons LtdCleanfill, construction and demolitionwaste, sand, subsoil, clay and compostBedfordRoad, TeKowhaiUp to 109,500 m3 per annumof cleanfill and C&D wasteTe KowhaiSandsCleanfill (preferably topsoil forrehabilitation)SH39, TeKowhaiConsented till 2021, but willlikely be at capacity by end of2011EnvirofertCleanfill (clay, soil, rock, concrete, brick,demolition products)(Take other materials such as plasterboardbut these are reprocessed)GeraghtysRoad,TuakauCurrently consented to 2019,but intend to extend consentsS D WatsonLtdCleanfill (concrete, clay and topsoil) forland contouringBucklandRd, Tuakau35,000 m3 per dayWhangarataQuarry,Ridge RoadQuarry LtdCleanfill and quarryRidge Road,BombayUp to 700,000 m314
