How do you kill a fish with your car? Simply drive it. Wear particles from your tires release a toxic chemical called 6PPD into the watershed killing fish. We want your help to replace this poison with innovative green, sustainable, alternatives. We are Coho Natural Solutions. 

Our business is built on the passion to discover and develop natural alternatives to a toxin that is released into the environment as your car tires wear. This compound, 6PPD, is a necessary evil required to protect rubber from oxidative attack. It KILLS fish! It gets ABSORBED by plants. HUMANS inhale tire dust and 6PPD gets into their bodies.  As a resutl, the chemical 6PPD is under growing scrutiny.  It's most likely a matter of time before it gets banned.

We plan to make tires more eco-friendly through nature by finding green alternatives. We’re inspired by the rich array of natural compounds that have the potential to replace 6PPD as natural antioxidants.  We aim to create sustainable chemistries that are kind to the environment. Our commitment is to thoughtfully identify, evaluate, scale, and launch green alternatives, bringing together science and nature for a cleaner future. Please consider joining us in this green endeavor.

6PPD reacts with ozone and other elements in the environment to form 6PPD-quinone, a highly toxic substance. When it rains, stormwater washes these tire particles from roads into local streams, rivers, and lakes. Once in the water, 6PPD-quinone can be lethal to certain fish species, such as coho salmon, even at very low concentrations. This chemical disrupts their biological systems, which may lead to death.

By supporting the development and adoption of green alternatives to toxic tire chemicals, you help protect fish and the health of our waterways for generations to come. Every choice and voice counts—join the efforts to advance chemistry into a "greener" and more sustainable and fish-friendly future.

Why COHO Natural Solutions?

The Coho salmon is more than our namesake—it's our inspiration and our reason for being. These magnificent fish are among the most vulnerable to 6PPD-Q toxicity, with even trace amounts proving lethal.

For generations, Coho salmon have been the lifeblood of Pacific Northwest ecosystems and communities. They're a keystone species, carrying nutrients from the ocean deep into forests and sustaining countless other species.

When researchers in Washington State discovered mass die-offs of Coho salmon returning to spawn, they traced it to a single culprit: tire chemicals washing off roads. That recent discovery helped to inspire our mission to find natural, safe, and effective alternatives.

Green Chemistry, Real Solutions

At Coho Solutions, we believe nature holds the answers. For millions of years, plants have developed powerful antioxidants to protect themselves. We're harnessing that same chemistry to create tire additives that perform brilliantly—without the toxic aftermath.

Our research will focus on naturally occurring compounds that can match 6PPD's performance while being completely safe for the environment. It's not about compromise—it's about innovation.
