Traditional Pavers Require A Large Amount of Energy and Resources To Produce

Tons of used plastics are wreaking havoc on our environment, and waste glass is overflowing our landfills. More than 5 trillion tons of plastic are floating in our oceans and beach pollution comprised of plastics and waste glass exceeds 6 billion tons. Any useful thing we can make from these two ingredients is a win-win! Glass, as opposed to plastics, is endlessly recyclable. Andela pulverizers create clean glass sand that can be used in a myriad of helpful ways. Shredding used plastics to mix with clean glass sand to create glass and plastic pavers is a beautiful solution.

Pulverized glass combined with a shredded plastic mix creates a lighter, stronger, and more durable paver. First, shredded plastics are safely heated to make a polymer binder in place of cement and water, then glass sand is mixed in. This mix is pressed by molds into decorative paver shapes and other useful shapes such as for curb construction. The pavers use up to 50% recycled glass sand/aggregate per volume which provides the structure, strength, and durability required.

Variety of Design

The plastics glass mix is made into a variety of designs using presses and custom-made molds.  Permeable paver, decorative patio block, or interlocking road pavers are all available.  A variety of surface construction designs are possible.

How Is Glass Aggregate Used to Create Pavers?

To create glass and plastic pavers, follow these steps:

  • Pulverizer the glass using the Andela glass pulverizer unit or system.
  • Shred the mixed plastics into little chips.
  • Mix the glass and shredded plastic chips.
  • Pour them into the extruder.
  • Take the melted plastics and glass mix and put into the mold and press.
  • Cool it off in water and you have the finished product.

Caltech Created Pavers, Bricks, Building Blocks, and Curb Units Using Crushed Glass

Tons of Waste Glass and Plastic Bottles Diverted From Landfill

Co-founder and CEO Jean Vezina leads Caltech’s growing environmental services portfolio. Processes in development enable communities worldwide to recycle their waste on location, drastically reducing waste and environmental damage while generating employment opportunities for some of the most vulnerable populations. Central to their commitment is upskilling local workforces to international standards, focusing on safety, environment, quality, and innovation.

Mixing recycled glass and recycled plastic bottles to create pavers is just one of their groundbreaking processes! Caltech uses Andela Products Mega-Mini glass pulverizer to produce the glass sand used in the mix. So far, they have created pavers, bricks, building blocks, and curb units.

“The Andela (GP-Mini) machine works without fail, every day. Love the simplicity and robustness of it. The resulting sand can be used in construction or in landscaping. Indeed, do not turn glass into the trash, turn it into a usable (and valuable) product.”

- Jean Vezina, CEO - Caltech Group

Millions of plastic water bottles Recycled in Timor-Leste.

In Timor-Leste hundreds of tons of plastic waste is generated each week. Caltech has helped manage waste by recycling plastic to create pavers, bricks, building blocks and curb units. To date, over 7 million plastic water bottles have been recycled since 2019, resulting in the production of 12,000 recycled pavers.
