Why is Glass Sand a Vital Ingredient for Polymer Concrete?
Lower Carbon Footprint
Polymer Concrete with glass sand can achieve a lower carbon footprint compared to Portland cement concrete
Long History
Glass and polymers have a long history of successful interaction
High Glass Load
Polymer concrete can contain up to 95% recycled glass sand
Non-Permeable
Inert, binds with polymer better than natural stone, hardness is higher
THE PROBLEM
A Two-Fold Problem: Waste Glass and Mined Stone
Waste Glass
Each year, over 8 million tons of glass end up in landfills due to low scrap values, high transportation costs, and inconsistent government support, leading to a dismal recycling rate in the U.S. Although glass is infinitely recyclable, it is often used as landfill cover, wasting a valuable resource.
Impact of Stone Mining and Aggregate Extraction
The mining of stone and aggregates for construction use causes significant environmental damage and creates a high carbon footprint, partly due to the transportation distances from mine to end-use. This practice contributes to ecosystem disruption and increased greenhouse gas emissions.
THE SOLUTION
Polymer Concrete
By combining pulverized glass sand with polymers, manufacturers provide a new lease on life for recycled glass. With construction, landscaping, and interior design applications, glass in the composite mix results in finishes that are wholly unique to the end product, as well as finishes that mimic sought-after architectural stone. The higher the glass load the more the product looks and feels like stone, making it possible to manufacture beautiful, sustainable architectural materials.
A SUCCESS STORY
Case Study: Caltech Creates Pavers, Bricks, Building Blocks, and Curb Units Using Crushed Glass!
Jean Vezina, co-founder and CEO, leads Caltech’s expanding environmental services, which focus on empowering communities to recycle waste locally. Caltech's efforts have helped to reduce landfill waste and environmental harm, while also creating jobs. Their approach emphasizes training local workers to meet international standards in safety, environmental protection, quality, and innovation.
One of Caltech’s notable achievements is the addition of recycled glass and plastic bottles to manufacture construction materials such as pavers, bricks, building blocks, and curbstones. Caltech has used Andela Products Mega-Mini glass pulverizer to turn waste glass and plastics into marketable products. According to CEO Jean Vezina, the machine is reliable and produces glass sand suitable for both construction and landscaping, turning discarded glass into valuable resources.
In a single project, they recycled 16 tons of glass into sand to create pavers. Additionally, since 2019, Caltech has recycled over 7 million plastic water bottles in Timor-Leste, resulting in the manufacture of 12,000 pavers made from recycled glass and plastic.
