Boral has secured approval from Sydney Water for its Blended High-Grade Compaction Sand (HGCS) to be used as an approved non-standard product.
The approval comes after more than a year of intensive trials involving Boral, Sydney Water and John Holland. The Boral HGCS will be used in the Upper South Creek Advanced Water Recycling Centre project which is Sydney Water’s largest infrastructure investment in Western Sydney.
“The incorporation of glass sand into Boral products has been a six-year journey from initially finding a suitable source, working with the NSW Environment Protection Authority (EPA) to establish a Boral-specific glass sand order, to now having approval from Sydney Water on our flagship Boral Blended High-Grade Compaction sand,” Boral recycled product manager Jeff Adams said.
“By using double-washed glass sand, we are providing a sustainable alternative to projects and demonstrating the strength of reusing materials to create a circular economy. We look forward to continuing our work with Sydney Water and its contractors to provide sustainable material into the market.”
Boral HGCS is a blend of natural sand and up to 40 per cent double-washed glass sand. Boral sources the glass for the double-washed glass from recycling company IQ Renew. The two companies worked together in the initial development stage to find the right grade of glass for Boral.
The Boral HGCS is produced at Boral’s Emu Plains recycling facility.
“We are pleased to have an innovative glass compaction sand alternative to supply to construction projects across NSW and for Sydney Water, specifically, given the critical supply of natural washed bedding sand,” Adams said.
“Our glass sand provides economic and environmental benefits when used instead of diminishing natural resources that require transporting long distances, as well as the obvious avoidance of glass into landfill.”
