The Victorian state government recently announced that the Kororoit Creek Road Level Crossing Removal Project will be the first rail project in the state with an innovative application of recycled glass sand.
Kororoit Creek Road is part of the VicRoads Principal Freight Network thoroughfare in Victoria’s west, which manages 22,000 cars to Laverton, Williams, Altona and elsewhere.
Procured from a raw materials supplier, recycled glass sand has been used as bedding fill for combined service routes on the project, as well as backfill for drainage piping.
Recycled glass sand is manufactured from inert recycled glass recovered from the glass recycling process. The report said that reusing this material reduces the amount of waste being sent to landfill and preserves our existing sand deposits. It also reportedly conserves energy that would otherwise be used to extract sand.
The cost of recycled glass sand in this case was about half the price of virgin material, due to shorter transport distances. It is also safer to handle as it presents a lower respiratory hazard than traditional sand.
