Dandelions are the new rubber trees. If you’ve ever dug up––or tried to dig up––dandelions, you may have noticed a bit of white latex sap that drips out of broken roots and stems. German molecular biologists and engineers have bred dandelions particularly rich in that sap. In concert with Continental, a German auto supply manufacturer, they opened a facility in Munster that produces rubber from field-grown dandelions. The product is blended with imported rubber sourced from rubber trees (Hevea brasiliensis) grown in Asia. The tires will be road-tested in Germany soon. “Dandelion tire” doesn’t sound as charming as “dandelion wine,” but given the shortcomings of synthetic rubber and Hevea‘s susceptibility to pests and diseases, it’s still a good idea.
