Pozzotive is a ground glass pozzolan and industrial filler made from 100% recycled post-consumer glass. It is a safer, sustainable and higher-performing material
that dramatically reduces embodied CO2 emissions in concrete.

Revolutionary Product Benefits

CO2 Reduction

CO2 Reduction

Pozzotive pozzolan can replace up to 50% of cement in concrete, reducing embodied CO2 emissions on a nearly ton-for-ton basis. Because concrete is the most abundant construction material in the world, the beneficial environmental impact of Pozzotive in concrete is dramatic.
Improved Concrete

Improved Concrete

Pozzotive produces a more durable, longer-lasting and higher-performing concrete that significantly improves its resistance to chloride penetration, sulfate attack, efflorescence and freeze thaw cycles.
Circular Economy

Circular Economy

Pozzotive is produced from 100% post-consumer glass, harvested and processed regionally, and used in local, sustainable building projects. This reduces transportation emissions and costly landfills and creates an optimal 'circular economy.'
Safer Material

Safer Material

Pozzotive is free of crystalline silica, a carcinogen, and toxic heavy metals, making it a safer and more environmentally friendly replacement for use as a concrete admixture, industrial filler and abrasive media.
Faq & technical Data

Revolutionary Industry Solutions

Glass Recycling Industry

The economics for glass recovery are quite poor and municipalities across the US are burdened with a rising inventory of post-consumer glass, a vast majority of which is landfilled. Pozzotive utilizes 100% of recycled glass regardless of glass color or the presence of ceramics.

Concrete Industry

The EPA estimates that the production of a ton of cement, a vital component of high-performance concrete, releases about a ton of harmful CO2. Replacing cement with Pozzotive Pozzolan reduces this CO2 on an almost ton-for-ton basis, and provides a consistent, readily-available, clean alternative that actually improves the lifespan and performance of concrete.

Pozzolan Industry

Environmental regulations and the rise of cost-effective alternative energy sources have moved electricity generation capacity away from coal-fired power plants, reducing the supply and quality of fly ash, the most common pozzolan. Pozzotive fills these supply voids with a high-performance, environmentally beneficial, locally-sourced and easily-replenished pozzolan.

Client Testimonials

A big focus of our team throughout the year was on sustainability. As the only team in the National Competition to utilize Pozzotive®, we were able to create a strong and sustainable cementitious blend that had a very light color.

Madeleine Murphree Civil Engineering Team | University of Florida 2019 and 2021 Winners ASCE National Concrete Canoe Competition

Through numerous structural and infrastructure concrete pours with Pozzotive ground-glass pozzolan replacing 20-40% of the cement, Urban Mining’s material, supply logistics, applied concrete knowledge, and overall communication have been consistently top-notch. Glad to have this locally-sourced option for well-performing, lower embodied carbon concrete that is also facilitating regional glass recycling.
