Course-medium, granula material used in construction. Often consists of sand, crushed stone, gravel etc. Mixed with binding material to create concrete or base.

Alloy Steel

Alloy steel is composed of different compounds such as zinc, nickel, copper, bronze etc. It is strong, tough and corrosion resistant.

Aluminium

Aluminium is resistant to corrosion and is therefore commonly used for doors, windows, roofs and exterior structures.

Asbestos

The term asbestos refers to a group of six naturally occurring mineral fibres: chrysotile, anthrophyllite, amosite, crocidolite, tremolite and actinolite. While asbestos has not been used in domestic building materials since the 1980s, it can still exist in older buildings. Since December 31, 2003 it has been illegal to sell, install or reuse asbestos in Australia. Check with your local waste authority about guidelines for the management of asbestos in recycling C&D waste.

Special Waste

Asphalt

Asphalt, also known as bitumen, is a sticky, black, and highly viscous liquid or semi-solid form of petroleum. It is primarily used for road construction where it is mixed with glue/binder to create a concrete base. Asphalt paving material is commonly reclaimed and recycled, reducing the demand for new raw materials. It is usually crushed and recycled back into asphalt. Recycling asphalt pavement and shingles results in major energy savings due to the high-energy process of creating asphalt binder from oil.

General Solid Waste

General Solid Waste

There are two types of general solid waste (GSW) putrescible and non-putrescible (GWS: NP). Putrescible waste contains organic matter (such as food or animal material) that is likely to quickly decay. Landfills that are licensed to accept putrescible GSW need appropriate and widespread facilities in place to deal with the high production of methane gas and associated odour. When assessing whether a material is defined as GSW, it is important to follow the NSW EPA waste classification guidelines that work through the waste hierarchy of pre-classified waste. www.environment.nsw.gov.au/resources/wasteregulation/140796-classify-waste.pdf

General Solid Waste

General Solid Waste (GSW) Soil

General Solid Waste (GSW) Soil is soil material that does not meet the criteria to be classified as Virgin Excavated Natural Material (VENM) or Excavated Natural Material (ENM). Generally, soils will not meet these criteria because of an abundance of foreign materials (construction and demolition materials) present in the soil. Soil waste is normally classified as GSW by default until further testing and investigation can classify the soil as a higher order material like VENM or ENM. When testing and investigation takes place, it is also a possibility that results can return a positive identification of hazardous materials, contaminants or asbestos and the GSW soil will be classified as a lower order waste stream (Hazardous Waste or Asbestos Waste).

General Solid Waste

Glass

Glass is made from liquid sand. It is 100% recyclable and can be recycled time and time again without losing its quality or purity. Green, clear and amber glass can all be recycled and the uses for recycled glass are endless and varied.
