Since 1973, SDI has been a leader and innovator in the field of manufacturing products from recycled tire rubber.  At our facility in Eugene, Oregon we mold our full product line of traffic safety, parking lot safety, and wheel chocks using both buffings and crumb rubber.  At our plant in Elkhart, Indiana we use crumb rubber to produce bases that sell by the truckload, thereby saving on freight cost to our mid-west and eastern customers.SDI's products are environmentally conscious and will meet your traffic and safety needs.  Contact us for high quality and excellent service.SDI continues to be a leader and innovator in the field of manufacturing products from post-consumer recycled tire rubber. We use 10 mesh minus crumb rubber or buffings according to the requirements of the product. Our environmentally conscious products will meet your traffic and safety needs,The energy required to produce a pound of virgin rubber is 15,700 BTUs, while that expended in the production of an equivalent amount of recycled rubber is only 4,600 BTUs...a savings of over 70%.The disposal of the estimated 200 million tires that are discarded annually is a costly problem of major proportion.

Natural rubber, the product of latex gathered from tropical trees and plants, accounts for a large quantity of the rubber raw materials consumed annually in the U.S. But the largest quantity is synthetic rubber, derived from petroleum (it takes half a barrel of crude oil to produce the rubber in one large truck tire). While recycled rubber makes up less than 4% of the total, many billions of pounds of rubber, comprised mostly of automobile and truck tires, are discarded each year.The raw material sources of natural rubber, Malaysia, Indonesia, Thailand, Sri Lanka, and Brazil, could, in years ahead, become uncertain or even inaccessible to U.S. industry due to political and/or economic reasons. And with the oil-producing countries exerting certain controls, the future price and availability of synthetic rubber, which is derived from petroleum, are open to serious question.Recycled rubber is found in a countless variety of industrial and consumer products, tires, wheel chocks, mats, dock bumpers, die-cut parts, fittings, and other obscure but essential components that are not always readily visible to the naked eye. In an era where energy conservation, materials availability, and solid waste management are of such pressing concern to us all, it is imperative that we have a better understanding of recycling and the value of recycled products, such as those made from recycled tire rubber.
