The heft and feel of a well-worn handle,
The sight of shavings that curl from a blade;
The logs in the wood pile, the sentiment of huge beams in an old-fashioned house;
The smell of fresh cut timber and the pungent fragrance of burning leaves;
The crackle of kindling and the hiss of burning logs.
Abundant to all the needs of man, how poor the world would be
Without wood.

Everard Hinrichs, quoted by Eric Sloane in A Reverence for Wood

Potatoes and Wood Panels

One of the major tussles in the wood industry over the past decade has been the effort by the EPA to ban formaldehyde-based resins in the production of particleboard, medium-density fiberboard (MDF), oreiented-strand board (OSB) and other wood products. Industry groups have understandably resisted the EPA's effort, since these resins have proven to be reliable, low-cost binders of wood particles for decades, and companies have been able to consistently improve the properties of their wood panels and products using them.

Many new resin systems have been explored as potential substitutes, since a small percentage of people are adversely affected by formaldehyde emissions, and formaldehyde itself is thought to be a carcenogic compound if a subject is exposed to it in sufficient quantities over protracted periods (a qualification, by the way, that does not apply to wood panels and products as manufactured and used these days). Nevertheless, EPA continues to push for a complete ban on the resins, companies continue to push back in the name of common sense...and scientists continue to look for alternatives that will satisfy all.

One such professor, Dr. Andrew Abbott of the University of Leicester, has the latest entrant in the formaldelhyde-displacement race. His solution? A resin system comprised of, among other things, starch of the common potato. Sounds appetizing...




Since I was once in this area of research myself, and have experienced the operational challenges of making an alternative binder system economically competitive with formaldehyde-based binders, I recognize that the key to Dr. Abbott's innovation lies in the coming challenge of commercialization, which he acknowledges near the end of the video. Nevertheless, I wish him and his team well and hope that they have, at last, discovered a game-changing binder that makes the world an even better place in which to live.

The potato...what isn't it good for?

Like! From Idaho, land of "Famous Potatoes" (check out our no-extra-charge standard license plate). Chuck, maybe you could post a pic here? I cannot.

Sorry, Jay. No pics in comments, as far as I can figure.
