BioWave™ Rubber Treatment Method
The BioWave process treats crumb rubber with a two-stage method combining microbial oxidation and microwave energy.
The resulting treated crumb rubber can be mixed with new rubber to create tires containing 20 percent or more recycled
rubber.

Market Assessment
Over the years, more than 800 million scrap tires have accumulated in stockpiles in the U.S. A tire’s physical structure, durability, and heat-retaining characteristics make these stockpiles a potential threat to human health and the environment.

Under recently passed legislation in Europe, landfill disposal of used tires is prohibited beginning in 2006. Also, the European Community has issued a directive requiring car makers to achieve close to 100 percent recycling of car components, including tires.

If tires containing BioWave treated crumb rubber can compete in cost and performance with new tires, the process should have a huge global market.

Patent Status
U.S. Patent No. 6,407,144 has been issued on this invention.

Stage of Development
BioWave treated crumb rubber was incorporated into a tire tread compound and the compound was tested for a number of performance parameters.
