Waste screening practices
Prior to disposal, incoming waste is subject to screening procedures aimed at ensuring that the landfill does not accept wastes that are prohibited. The screening occurs prior to entering the landfill, at the gatehouse/acceptance point, the transfer station and the tip face
A classification process of deposited wastes enables the identification of the potential for the waste to release chemical contaminants into the environment through contact with liquids. Wastes may be classified as follows:
Inert - this waste type is the least likely to undergo environmentally significant transformations and therefore should not release significant quantities of greenhouse gases or leachates contaminated with nutrients and / or chemicals.
Solid - this waste type can include putrescible waste, is likely to release higher quantities of greenhouse gases and leachate contaminants than inert waste and consequently needs to be managed with greater care.
Industrial - this waste type may contain four times the levels of greenhouse gases and leachate contaminants than solid waste. Industrial waste is not accepted at the Grafton Regional Landill.
Hazardous - this waste type contains contaminants at levels high enough to require treatment to render them safe before disposal. Hazardous waste is not accepted at the landfill, however the Houshold Hazardous Waste Store provides a repository for orphan waste pending disposal.
Waste re-use and recycling practices
The materials recovery facility (MRF) located in Grafton is the principal site for recycling activities within the Grafton Region. A drop off facility however is maintained at the Regional Landfill for the following material: Glass, PET, HDPE, Aluminium Cans, Steel Cans, Paper / Cardboard, Waste Oil, Batteries, Non-Ferrous Metal, Ferrous Metal, Green Organics, Tyres, Timber, Demolition rubble, drumMUSTER containers.
In addition to drop off facilities, landfill staff and/or contractors are engaged to recover unsorted material suitable for reuse or recycling. This material includes furniture, building material, car parts and other household items, which are marketed through the Grafton materials recovery facility. Public scavenging at the tip face is prohibited.
Habitat restoration areas
A Habitat Restoration Plan has been implemented around the perimeter of the Landfill which includes new plantings of local provenance plant species and the restoration and maintenance of existing regrowth vegetation. The habitat buffer when completed will be 200m wide and approximately 1500m in length having an approximate area of 30ha. The buffer encircles the north, south and eastern perimeters of the final landfill area and will link up with remnant bushland on the western side. It is envisaged that impacts on flora and fauna habitat will be mitigated and an effective visual barrier to the landfill will be provided.
