Green Initiatives

"The great work that is being done at KN Rubber...is a real example of the green economy at work."

For over four decades, KN Rubber has been at the forefront of efforts to minimize the environmental impact of manufacturing. Our commitment to rubber and tire recycling has diverted hundreds of millions of pounds of waste rubber from landfill. Our Nyracord® and Symar® brand products are 100% recycled; as a result, our construction products have the potential to count toward LEED (Leadership in Energy and Environmental Design) credits.

Beyond the manufacturing process, it is our policy to conduct all of our operations in an environmentally responsible and sustainable manner. KN Rubber has achieved ISO 14001:2004 certification, the international environmental standard. Consult our Environmental Policy for further information.
