If you are going to use a plant as a renewable resource to create sustainable materials suitable for automotive use, you may as well start with a weed. After all, anyone who lives in states with plenty of lush, green grass knows how prevalent dandelions are in the summer months.

And so it's not terribly surprising that researchers from Ford and The Ohio State University are working on new rubber and plastic compounds created from the milky white juice that seeps from the stem of the yellow-flowered weeds. The specific plant being used is the Russian dandelion, otherwise known as Taraxacum kok-saghyz to all you budding botanists out there.

Before any dandelions actually start showing up in our cars, Ford needs to ensure the rubber and plastic produced in this process is up to its quality standards. If that happens, such plastics could be used for floor mats, cupholders and interior trim pieces.

Another potential natural plastic resource is the guayule (apparently a shrub that grows naturally in southwestern U.S.). Click past the break to read the entire press release from Ford.

Weed 'Em and Reap: Ford, Ohio State Look to Put Dandelion Roots to Use in Cupholders, Floor Mats and Interior Trim

- Potential use of dandelion root as a rubber substitute is another example of Ford's investment in sustainable materials for its vehicles including soy foam seat cushions, wheat straw-filled plastic for interior trim and recycled cotton from blue jeans as sound-dampening material

Dearborn, Mich., May 10, 2011 – When homeowners see dandelions sprouting, they start thinking of ways to get rid of the weed, but researchers at Ford and The Ohio State University see a plant that can serve as a new sustainable resource for rubber.

"We're always looking for new sustainable materials to use in our vehicles that have a smaller carbon footprint to produce and can be grown locally," said Angela Harris, Ford research engineer. "Synthetic rubber is not a sustainable resource, so we want to minimise its use in our vehicles when possible. Dandelions have the potential to serve as a great natural alternative to synthetic rubber in our products."

Not all dandelions are created equal, meaning not all can be used as a sustainable resource for rubber. The suitable species for this project is the Russian dandelion, Taraxacum kok-saghyz (TKS), which is being grown at The Ohio State University's Ohio Agricultural Research and Development Center (OARDC). A milky-white substance that seeps from the roots of this species of dandelion is used to produce the rubber.

"Managing weed problems is essential to developing TKS as a commercially viable domestic source of natural rubber in the U.S.," said Bill Ravlin, associate director of OARDC.

Ford could potentially use the substance as a plastics modifier, to help improve the impact strength of plastics. The material might then be used in places such as cupholders, floor mats and interior trim.

"It's strange to see weeds being grown in perfectly manicured rows in a greenhouse, but these dandelions could be the next sustainable material in our vehicles," said Harris.

Before the dandelion-derived rubber can be put to use, Ford researchers will assess the initial quality of the material to evaluate how it will perform in a variety of plastics that are used in vehicles and to ensure it meets durability standards.

Besides the dandelion, the team also is looking into the use of guayule (a southwestern U.S. shrub) as a natural rubber, which is provided by OARDC and can also be grown domestically.

Eco-friendly solutions
Ford's "Reduce, reuse and recycle" commitment is part of the company's broader global sustainability strategy to reduce its environmental footprint while at the same time accelerating the development of advanced, fuel-efficient vehicle technologies around the world.

Over the past several years Ford has concentrated on increasing the use of nonmetal recycled and bio-based materials whenever possible, provided these materials are environmentally favorable in the specific application. Examples include soy foam seat cushions, wheat straw-filled plastic, recycled resins for underbody systems, recycled yarns on seat covers and natural-fiber plastic for interior components.
