Recycled rubber technology

According to E.W.M.C. International Inc., the Emery microwave process has been used commercially to recycle rubber tires and process medical waste. Research and development is currently being conducted on the application of the technology to treat contaminated media. All information is from the vendor and has not been independently verified. 

Smith Environmental is the owner of the battery waste treatment process (BWTP), a technology that uses washing, liberation, and gravity separation to treat waste from battery wrecking operations. Treatment by the BWTP process typically yields rubber, plastic, and a concentrated lead product. The vendor claims this is a closed-loop system where all water used in the process is recycled. The technology was commercially available and had been used for full-scale cleanups in 1995. RIMS were unable to obtain information from the vendor, so current commercial availability is unknown. 

Recycling rubber from tires for use in asphalt pavements is a promising technology. Asphalt pavements incorporating tire rubber are claimed to have twice the lifetime of ordinary asphalt, but they can cost twice as much. Pavements with crumb rubber additives consume over one million tires per year now, and both asphalt-rubber and rubber modified asphalt concrete have considerable potential for expansion. If Federal, state, and local governments promote much broader use and demonstration of this technology, perhaps the technical issues will be resolved and usage will expand.

Method B also differs from Method A in that it is an ultrasonic technique and the use of this technology addresses the problems that may be caused by tackiness and the static electrical forces that recycled rubber particles may exert on each other to form agglomerates. The problem of agglomeration can be particularly prevalent for particles that are 80 mesh or finer. The use of ultrasonic agitation eliminates the formation of agglomerate by dispersing the particles.
