Recycling - The Responsible Alternative

Contact Opta Minerals Inc.

Opta Minerals continues to build on a tradition of handling industrial products in a safe and responsible manner. Our company roots can be traced back to the early 1870’s when we were active in the processing and supplying of mineral based products for industrial markets. Our current site has been operational in the recycling materials business since the 1930’s. The evolution of our company included the environmentally responsible management of renewable resources. Opta Minerals is truly an environmental success story; the preservation of our environment is the very foundation we have built upon. We operate a modern recycling facility at our 32 acre site in Waterdown, Ontario in compliance with our unique recycling permit.

Let us profile your current by-product management. A successful partnership with Opta Minerals will improve your bottom line, limit your long-term liability, assist you in meeting government waste reduction targets and improve our environment.
