Business opportunities

Repurposed glass and its derivatives are currently incorporated into some Montreal sidewalks (most notably around the Montreal Museum of Fine Arts and in the Quartier des spectacles) and are used as glass mulching in landscaping projects. A number of SAQ stores already have concrete floors and counters made with glass aggregates, giving a second life to more than two million bottles.

To learn more about current research and the advantages of using glass in commercial applications, see the Research and Development section.

Key companies in the concrete industry have begun to follow suit.


Here are some real-life uses

Cement additive

Adding glass powder to concrete increases the material’s structural strength and water resistance and facilitates concrete placing as compared with conventional concrete. Recycled glass can also be very useful in engineering and public works projects. Using glass powder as a cement additive is now systematically included as a tendering condition in all SAQ calls for tender for new store construction projects.

Sound attenuation wall

Jansen Industrie has built the first-ever concrete sound attenuation wall that includes glass powder. The wall is located in Boucherville, on Autoroute 20 at the corner of Ampère and Normandie streets. Installed in collaboration with the Ministère des Transports du Québec, the wall is comprised of 230 concrete blocks to which 53,000 bottles (25 metric tons) of glass, in the form of powder, have been added. The company has developed a process that enables it to replace between 20% and 30% of the conventional concrete powder with recycled glass powder in its sound-attenuating architectural blocks.

Another use for glass powder is being tested by the City of Montreal in a reconstructed section of sidewalk on Poutrincourt Street in Ahuntsic-Cartierville borough. If successful, the trial could pave the way for the regular use of glass powder in sidewalks throughout the city. For more information, watch this City of Montreal video.

Landscaping mulch

Recycled glass mulch is made from finely crushed glass containers. As it consists mainly of glass in various colours (clear, green, amber) that has been transformed into a kind of coarse sand, it is light green in colour, not unlike a pistachio. Glass mulch is non-toxic for humans and pets and doesn’t cut or otherwise harm the skin when handled with bare hands. Landscaping specialists can refer to the technical specifications (French only) for more information.

Also sold in bags as recycled glass sand for pool filtering systems, it can be found in most of the following outlets :


Environment-friendly furniture

An example of the innovative potential of recycled glass is this bench, made by Jansen Industrie and incorporating 226 glass bottles transformed into powder. As glass powder makes concrete more impermeable, the bench is also graffiti-proof. The SAQ donated the bench in the accompanying photograph to the Montreal Museum of Fine Arts in 2013.

Glass aggregates in interior finishing materials

Concrete slabs in many SAQ stores contain glass powder and aggregates that replace limestone, a natural resource needed to make concrete. In addition, glass aggregates can be incorporated into countertops.

Trial uses

Once transformed into precipitated silica, glass can be used in paint, ink and tires as a filler to strengthen silicone and rubber. Paint incorporating powdered glass is currently being tested in the offices of the SAQ’s Montreal distribution centre. Transformed glass is also being used as an abrasive in toothpaste, since it doesn’t scratch tooth enamel.

Environment-friendly slab

Gaudreau Environnement has designed an environment-friendly slab made entirely from recycled materials. Manufactured using only hard-to-recycle items, the product is the very model of an integrated eco-responsible process. Each environment-friendly slab is comprised of glass (75%), plastic bags (20%) and porcelain (5%). Available in different colours and sizes, the slabs are an effective alternative to conventional surfacing products and are ideal for all urban development projects. A green, totally made-in-Quebec innovation!
