Sustainability is at the center of everything we do at Sustainability Sand and Stone.
We offer a central South Auckland recycling facility for non contaminated hydro excavation waste.
We process using cyclones and filtration, along with vibration, which uses less energy than crushing. The embodied carbon from these processes is generally minimal compared to other market options.
Aggregates are extracted and available for use. This displaces the need for virgin aggregates being both used, and transported.
Non Potable water is extracted and available for re-filling the hydro excavators
