Recycled Granite Has Lots of Design Possiblities

Granite Scraps, normally sent to landfill

In keeping with my theme of writing about products made from waste material, I was contacted by a company called Green Stone Granite, based in Guelph, Ontario. Green Stone Granite is a new enterprise that takes leftover granite from building jobs and turns it into new products. Dana Laferriere, my contact at Green Stone explained to me that after counters or flooring or tiles have been made from granite, the off-cuts are usually sent to landfill. According to Green Stone’s estimate, 30-40% of granite is “waste”, as in off-cuts and scrap, and is sent directly to landfill. Green Stone has asked local granite manufacturers  (Guelph and surrounding area) to send their scraps to them instead of landfill.

Green Stone Granite’s goal is to become a zero waste facility. Dana said,

We need to get our name out there to educate the public that there are different uses for granite, and now the option for recycled granite. Once we do that and our business grows, we will be able to put the money into achieving a zero waste facility. Currently we are able to re-purpose on average 70% of the granite that comes to our facility. Our goals for the future is to start producing landscaping material with the remainder including aggregate which would bring that to 100%.

Split Stone granite tiles for kitchen

Feature Wall made from split stone granite scrap

Their most popular product is the split stone. It is rough, like any natural stone in its finished form.  The split stone has many applications from kitchen backsplashes, fireplace surrounds to outdoor uses such as pavers and for outdoor kitchens. They also create cutting boards/cheese trays and are in the process of developing granite ice cubes (whiskey stones).

Cost: The cost is comparable to a marble or glass backsplash.

Delivery: They are able to deliver the product to the Toronto area, and are currently speaking with eco building stores about carrying it directly in Toronto.

Installation: Installation is similar to installing traditional tile, however the stones are dry stacked so no grout is required. The benefit to our product is every project is unique and there are endless possibilities of colour combinations.

    Thank you very much for your question Bettina.

    We currently do not test for radon. According to a 2010 test done by Health Canada. The types of granite that they tested commonly purchased in Canada; none were found to have significant levels of radon. At this time, Health Canada expects that the main source of radon in a house will be soil gas which is drawn inside naturally

    This is something, however we will continue to monitor. Again, thank you for your question.

    Hi Bettina,
    Good question. I’m not sure, but I’ve left a note with Dana to respond re the radon.

    Thanks Kathy. Do you know if they test the granite for radon before recycling it into their product?
