Thanks to the GP-Mini, we can now recycle 100% of all type of glass we collect or glass debris we generate from our site without major efforts as it separates corks, lids and labels from the glass and produce a nearly debris free sand – gravel without sharp edges.

Jean Vezina | CEO


Caltech Construction specialises in providing diverse services to support the construction, environmental, marine and oil and gas sectors.

The CEO Jean Vezina approached Waste Initiatives to explore the concept of turning recycled glass into sand that can be used in
their plastic recycled pavers. It will help Timor-Leste with its recycling challenges, create new jobs, and streamline Caltech’s plastic paving manufacturing process.

The Waste Initiatives team consulted with Jean and worked out the best business case for a glass breaking system. Their goal is to reduce the amount of waste we send to the landfill by 70% within five years.


Waste Initiatives proposed their entry-level glass pulveriser, the GP-Mini, that produces an aggregate and sand mix and separates corks, lids and labels.

The unit has a relatively small footprint and has a throughput of up to 1.5m3/hr on whole and broken glass.

Jean says: “The unit is simple to operate, reliable and requires minimum maintenance. We now use the glass sand-gravel generated as pipe bedding on our site or as sand in our plastic sand pavers.”

“With this technology available, I do not see any reason to dispose of glass into landfill!”

OzTyre Recyclers

If you want a machine, just ring up Jason. Waste Initiatives will be with you for the long term. The partnership between Waste Initiatives and OzTyre Recyclers has been fantastic. We told Jason what we wanted and how many tyres we needed to produce in an hour. He came up with many different options until we have the shredder we have now.

OzTyre Recyclers approached Waste Initiatives with an ambitious target to be one of the first in the sector in Australia to recycle 100 per cent of used tyres and have an Australian market for the end-product.

Before the export ban, tyres were baled and exported. They had to shift their strategy to processing rubber to chip suitable for export and reuse as Tyre-Derived Fuel (TDF) and for further processing.

Tyre Stewardship Australia in conjunction with Waste Initiatives helped and advised them on local and overseas requirements. As a result, a further interest arose in taking rubber all the way down to rubber crumb & powder.


The first step was to put the wheels in motion by installing a newly designed shredder system developed over the last two years. The old baling equipment was processing 400 tyres an hour, and they wanted an equivalent workflow with the new equipment.

The result is a tyre shredder with an integrated rotary screen. The turnkey system includes infeed and outfeed conveyors, controlled by a main PLC control station. It’s been designed and engineered to take whole tyres down to 50mm chip and can process up to 550 tyres per hour.

The second phase is currently underway for installing a tyre crumb & powder plant to provide rubber for a range of applications including some exciting new markets.

Since installation, the unit has proven reliable, safe & user-friendly and is consistently achieving high bin payloads across both timber and cardboard waste streams. Our experience with the team at Waste Initiatives and their product has been completely satisfactory, and we have no hesitation in recommending them – great work guys.

Lyndon Bain | Group Facilities Manager


Introduced to Volkswagen by Remondis Australia, Waste Initiatives were engaged to assess a deteriorating compaction system at VW’s parts distribution centre at Chullora.

During Waste Initiatives’ site assessment, it became apparent that the range of cardboard box sizes/thicknesses and the timber crates/ pallets being disposed of were proving unmanageable and increasingly costly with the existing compactor.

Space being at a premium, the resulting waste overflow due to the inferior compaction performance of their old machine left the site with an ongoing logistics and material handling challenge which required excessive labour and increased collection services – inflating the site operating costs.


The ideal solution for Volkswagen was quickly indentified as the mutli-use RPV7700 Roll Packer fitted out with a special-purpose roller to ensure efficient compaction across both timber and cardboard waste streams, without cross- contaminating the bins.

An additional RP7700 Roll Packer was specified for VW’s sister DC in Melbourne.

Upon installation, the site immediately proved the benefit of the original Roll Packer – seeing a significant increase in bin payloads, effective crushing of the most challenging of their waste profiles (including over size crates & boxes), and a safe & reliable operating process delivering substantial savings on their operating costs and freeing up their labour resources.
