We Recycle 100% of Glass

75% of the national total glass supply is landfilled each year, because traditional processing relies on technology and markets that can’t effectively recycle all the glass. Due to our new and innovative process, all glass can now be recycled and repurposed, and kept out of landfills.

Decrease GHG

Cement is one of the largest contributors to greenhouse gas emissions on the planet. By replacing a substantial portion with our pozzolan alternative in concrete mixtures, we can dramatically decrease emissions. For every ton of cement replaced with glass powder, we save 1 ton of GHG.

Environmentally Friendly & Non Toxic

Our product is virtually 100% free of Crystalline Silica and heavy metals that can be toxic to humans and cause adverse health and environmental effects. It is even safe for application in agriculture as a clean pesticide replacement.

Featured Application: Pozzolan


Have you ever wondered why the Roman Colosseum has lasted thousands of years while modern roads and bridges haven’t? The Romans used volcanic ash to make their concrete. Volcanic ash is amorphous silica – just like SiONEER’s glass pozzolan, Centurion.

Centurion is a clean, non-toxic replacement to fly ash. Made from 100% post-consumer recycled material, helping to not only decrease GHG emissions, but due to the chemical composition of the glass pozzolan – amorphous silica – mitigates the risk of Alkali-Silica Reaction (ASR) while increasing the overall compressive strength of concrete.

Materials Spotlight: Recycled Glass in Concrete

Glass pozzolan solves three different issues at once: eliminating glass going to landfill, making concrete last significantly longer, while at the same time dramatically reducing GHG emissions. Our vision is to hit that trifecta at scale.
