About Western Aggregates
|
It is our understanding that 16% of New Zealand’s waste stream is recyclable hard
fill. Our company and others like us are working hard to reduce that figure. With plant efficiency, we estimate over 99% of the waste concrete and excavated soil tipped at our West Auckland site gets recycled into a variety of quality products suitable for construction and other similar projects. We also offer a free site inspection and advice service, not matter how big or small. |
What we do
At Western aggregates, we recycle hard fill and supply quarry products. We offer delivery and pickup.

Recycling process
We have two areas of operations – Concrete and Soil. Concrete is a year round operation, and the soil operation is seasonal with a closedown over the winter months.
CONCRETE
When your waste concrete is crushed, any steel is removed with magnetic separators and sent away for recycling. Primary product is then crushed further and screened into various graded secondary products suitable for construction, drainage, retaining walls and other projects.

SOIL
The bulk of the raw soil we accept generally comes from contractors stripping sites for new construction. We process the soil to remove contaminants such as wood, plastic, concrete etc. It is amazing how the raw soil is transformed into a quality product that is easily handled and spread.

ENVIRONMENTAL POLICY
As members of the Recycling Operators of New Zealand (RONZ ) and following our company ethos, we are continually working towards improving the environmental efficiency of our operation. Moving to reduce our carbon footprint, we have electrified as much plant as possible, and when able intend to be purchasing green electricity. |

ENVIRONMENTALLY PRODUCED PRODUCTS - THE WAY FORWARD We believe there is a good market for environmental products, especially when they are cost effective to purchase. The service we provide not only saves on filling valuable landfill sites, but depending on the job location can also have a direct impact on transport costs. At over $1.00 per minute for transport these days, trucking material further than needed can make a substantial difference to a projects cost. The type of operation we run can be commonly found in progressive countries, but up until now most operators in New Zealand seem to have not developed crushed concrete products much past a basic filling product, hence a limited sales market. We take it beyond that by producing a range of quality products. |

COST EFFECTIVENESS
People sometimes ask why we charge tip fees for their waste concrete and soil when we need it for processing. Unlike a quarry or landfill where there is only one income stream, we have two. This means we can reduce the prices of tip fees and of product supply to ensure a steady flow of material in and out. If a price comparison is made with those of traditional suppliers like landfills, quarries and supply yards, you should be pleasantly surprised. |
