Recycled glass feedstock
A circular solution that gives an existing resource new value.
The people behind your supply
Aaron Stevens
Glass to Sand Brisbane operations
Aaron leads Glass to Sand Brisbane, the operation converting post-consumer waste glass into engineered silica sand. That feedstock supports MaxSil and the wider Sustainable Concrete Group materials portfolio.
For growers, the circular story starts here: real processing equipment, locally recovered glass and an Australian operation connecting resource recovery with plant nutrition. The same waste stream serves agriculture and the built environment.
Aaron and the circular supply chain at SCG
David Archer
MaxSil founder and inventor
David developed the patented process that turns recycled glass into plant available silicon. His materials science work is the foundation of MaxSil's Australian-made fertiliser and the field trials behind it.
Oscar Ledlin
SCG co-founder and strategic investor
Oscar brings industrial development, investment and commercial experience to Sustainable Concrete Group. He is helping build the platform behind MaxSil's growth and circular materials production.
Science is only useful when it works on farm.
Katrina
Agronomist, Peel Ag
With 33 years in agronomy and a fifth-generation farming background, Katrina explains why she uses MaxSil on her own hard red soils. Hear where plant available silicon fits in a fertiliser program focused on costs and farm income.
Andrew Kennett
National Sales Agronomist
Based in Toowoomba, Andrew brings consulting agronomy experience across Australia and the South Pacific. His role connects MaxSil's field evidence with practical conversations about crops, application and supply.

Inside the Brendale ball mill.
Our Brisbane facility turns recovered glass into fine silica products. Ball milling is part of the processing behind MaxSil: the grind matters because plant available silicon, not simply total silicon, is what growers need to compare.
The plant also offers toll milling and contract ball milling through Micron Materials, our sister business.
Fully circular. Strong sustainability focus.
Put an existing resource back to work.
MaxSil gives post-consumer glass a productive second life as plant nutrition. Resource recovery, Australian manufacturing and better use of farm inputs sit at the heart of what we do.
We focus on a circular supply chain, not extracting virgin silica for every new tonne. Sustainability is built into the feedstock choice and the way our plant supports multiple useful materials.
Plan ahead for available stock.
Our circular production serves more than one market. Finished MaxSil stock is limited to what is available from production, so talk to us early about larger volumes and seasonal requirements. Confirm current availability and delivery timing before planning your application.
