A Veggie-Plastic Coating May Be A ‘White Knight’ For Threatened Yellow Cedar


Reno, Nevada, August 26 2015 – With Yellow Cedar edging ever closer to joining the US Endangered Species List, a vegetable oil based plastic may be its white knight when it comes to helping reduce pressure on its use for repairing giant wood water flumes.

The veggie-plastic has the unique property of molecularly bonding to any wood thus making its application with other plentiful types a wood a viable alternative where long term contact with water is concerned.

“We had great success with our Ecodur coating on a giant water flume made of Yellow Cedar in Washington State,” commented Castagra CEO, Peter Roosen. “But it works just as well as any wood because of how it binds to any cellulosic material forming a permanent, waterproof layer that, as it happens, is also rated for safe contact with drinking water.”

Roosen said Ecodur is very much a green product being made of castor oil and the commonly found mineral gypsum.

“It’s completely non-toxic, no volatile organic compounds, no solvents, and totally inert biologically when its out there in the environment. The oil is renewable and any waste is fully recyclable.”

Yellow-cedar is one of the world’s toughest woods with exceptional longevity and durability. It is widely used for shingles, posts, poles, marine pilings, small boat hulls, oars and paddles, water and chemical tanks, exterior doors, and window boxes. Structural grades are commonly used for exterior applications such as bridges, decking, stairs and for landscaping.

If the conifer is listed, it would become the first tree in Alaska to be protected under the federal Endangered Species Act. The cedar is found from southeast Alaska down to Northern California.

Roosen says in his home province of British Columbia, Yellow Cedar has enormous importance to First Nations people.

“It is a widely-recognized symbol of the Northwest Coast. The cedar has been part of their lives for thousands of years and was a great resource to them in their daily lives and permeated their spiritual beliefs and ceremonial life of coastal First Nations and still does today.

“If the use of our veggie-coating can make a contribution to lessening the pressure on its use, then so much the better. Over-arching all of this though is climate change which is suspected as being the main culprit for the rapid decline of cedar forests where often there is insufficient snow cover in winter to protect the shallow roots.”

Roosen added: “Ecodur was developed in British Columbia, one of the last great areas of Yellow Cedar resources. Let’s hope it can be a white knight and help consumers realize, whether they be flume repairers, shingle, boat, or even bridge builders, that other woods can potentially be used instead if they get this unique protective coating.”

“Climate change appears to be gathering pace with its effects showing up all over the place, whether it be longer droughts, the dying trees in your city, the shrinking reservoirs, or missing snow on your favorite ski resort.”
