Reducing landfill and providing a sustainable alternative to quarried aggregate
Why recycle waste concrete?
By recycling waste concrete and re-using as recycled crushed concrete eco-aggregate:
- it reduces the burden on New Zealand’s landfills and extends their life
- haulage companies can avoid the per tonne tip levies at landfill sites
(levies which are expected to increase in 2020!) - we'll help to preserve our landfill resources for the truly non-recyclable waste
- it helps reduce the pressure on natural aggregate – natural aggregate is a finite supply and apart from recycled crushed concrete, there are no known substitutes
- using a local site for tipping and metal supplies means shorter trips, less running costs, less carbon emissions, less road congestion, less road wear and tear
Why use recycled concrete eco-aggregate?
When you choose recycled crushed concrete eco-aggregate for your project:
- it’s good for business and for New Zealand’s environment
- it’s clean, green, and lean in price!
- it’ll help keep construction costs down
- it’ll improve project efficiency and job cost – recycled crushed concrete eco-aggregate yields more volume by weight (up to 15%)
- you’ll help to conserve our natural quarried aggregate resources
- you help reduce the environmental stress from quarrying, and reduce pollution from trucking metal from quarries (sometimes carted over 100 km from source to site in Auckland)
What can crushed concrete be used for?
The appropriate grade of recycled crushed concrete eco-aggregate can be used almost anywhere natural aggregate is currently used in commercial or domestic projects, including:
- General fill, eg beneath grass, behind retaining walls etc
- Loose on driveways, as unsealed hard stand areas, as paver base for landscaping
- As basecourse or sub-base for footpaths/pavements, medium trafficked roads, driveways and other asphalted or sealed surfaces
- As basecourse under building foundations/slabs
- In civil works such as stopbanks, earth bunds, soakage pits, drainage channels and as pipe and cable trench bedding and backfilling
- Farm tracks, bases and foundations for implement sheds, dairy sheds, etc
- Domestic drainage systems
- Bulk fill, eg embankments and retaining wall construction
- Railway Ballast (subject to Ballast Track Specification 140 compliance)
