TRIBUTE TO RUST

March 1, 2013

By Kristin Johansson,  PCI Magazine

I recently came across an inspiring story from Harley-Davidson® regarding a highly corroded motorcycle. This particular motorcycle, a 2004 FXSTB Softail Night Train, drifted for more than a year across the Pacific Ocean following the tsunami that devastated parts of northern Japan in 2011. The motorcycle was recovered off the coast of British Columbia by a man named Peter Mark, when it washed ashore at low tide. He discovered the motorcycle, still bearing its Japanese license plate, in a container where the bike was being stored by its owner.

Mark worked with news agencies and representatives from Deeley Harley-Davidson Canada and Harley-Davidson Japan, and eventually found the owner, Ikuo Yokoyama, who lost his home and members of his family in the tsunami. Still struggling to rebuild his life in the aftermath of the disaster, Yokoyama declined Harley-Davidson’s offer to restore and return the bike to him, although he was grateful for the offer and touched by the outpouring of support from Harley riders around the world. He asked to have the motorcycle preserved in its current condition and displayed at the Harley-Davidson Museum as a memorial to those whose lives were lost or forever changed on that day. The bike is now under glass in the Harley-Davidson museum in Milwaukee. As per Yokoyama’s request, it remains un-restored and largely untouched.

In this situation the corrosion is a tribute for all to see. However, corrosion is normally a widespread, costly and hazardous problem that no one wants to see. The American Galvanizers Association estimates that metallic corrosion costs nearly $423 billion annually in the United States, and about one third of that is noted as avoidable corrosion – a cost that could be eliminated if proper corrosion protection methods were in place.

GREEN CHEMICALS

The Green Seal certification is granted by the organization with that name and has a great number of members contributing with the requirements to pass a raw material or a chemical product as "green". Generally for a material to be green, has to comply with a series of characteristics like: near neutral pH, low volatility, non combustible, non toxic to aquatic life, be biodegradable as measured by oxygen demand in accordance with the OECD definition.
Also the materials have to meet with toxicity and health requirements regarding inhalation, dermal and eye contact. There is also a specific list of materials that are prohibited or restricted from formulations, like ozone-depleting compounds and alkylphenol ethoxylates amongst others. Please go to http://www.greenseal.com/ for complete information on their requirements.
For information on current issues regarding green chemicals, see the blog from the Journalist Doris De Guzman, in the ICIS at: http://www.icis.com/blogs/green-chemicals/.
Certification is an important — and confusing — aspect of green cleaning. Third-party certification is available for products that meet standards set by Green Seal, EcoLogo, Energy Star, the Carpet & Rug Institute and others.
Manufacturers can also hire independent labs to determine whether a product is environmentally preferable and then place the manufacturer’s own eco-logo on the product; this is called self-certification. Finally, some manufacturers label a product with words like “sustainable,” “green,” or “earth friendly” without any third-party verification.
“The fact that there is not a single authoritative standard to go by adds to the confusion,” says Steven L. Mack M.Ed., director of buildings and grounds service for Ohio University, Athens, Ohio.
In www.happi.com of June 2008 edition, there is a report of Natural formulating markets that also emphasises the fact that registration of "green formulas" is very confused at present, due to lack of direction and unification of criteria and that some governmental instittion (in my opinion the EPA) should take part in this very important issue.
