The invention is a method of using enzymes from thiophyllic microbes for selectively breaking the sulfur rubber cross-link bonds in vulcanized rubber. The process is halted at the sulfoxide or sulfone step so that a devulcanized layer is reactive with virgin rubber. 8 figs.

Nonaqueous ozonation of vulcanized rubber

Patent Serkiz, Steven M.

A process and resulting product is provided in which a solid particulate, such as vulcanized crumb rubber, has the surface functional groups oxidized by ozonation using a nonpolar solvent. The ozonation process renders the treated crumb rubber more suitable for use in new rubber formulations. As a result, larger loading levels of the treated crumb rubber can be used in new rubber mixtures.

Microwave treatment of vulcanized rubber

Patent Wicks, George G ; Schulz, Rebecca L ; Clark, David E ; Folz, Diane C

A process and resulting product is provided in which a vulcanized solid particulate, such as vulcanized crumb rubber, has select chemical bonds broken by microwave radiation. The direct application of microwaves in combination with uniform heating of the crumb rubber renders the treated crumb rubber more suitable for use in new rubber formulations. As a result, larger particle sizes and/or loading levels of the treated crumb rubber can be used in new rubber mixtures to produce recycled composite products with good properties.

Reconstituted polymeric materials derived from post-consumer waste, industrial scrap and virgin resins made by solid state pulverization

Patent Khait, K.

A method of making polymeric particulates is described wherein polymeric scrap material, virgin polymeric material and mixtures thereof are supplied to intermeshing extruder screws which are rotated to transport the polymeric material along their length and subject the polymeric material to solid state shear pulverization and in-situ polymer compatibilization, if two or more incompatible polymers are present. Uniform pulverized particulates are produced without addition of a compatible agent. The pulverized particulates are directly melt processable (as powder feedstock) and surprisingly yield a substantially homogeneous light color product. 29 figs.

Absorption of hydrocarbon vapors by vulcanized rubber

Patent - in OSTI.gov collection Snyder, R.H.

A method of substantially precluding accumulation of combustible hydrocarbon vapors in the air of a closed substantially empty holding tank is described comprising: placing an effective combustion preventing amount of vulcanized rubber particles in the size range from 6 mesh to 200 mesh in contact with the hydrocarbon vapors within the holding tank, and, absorbing the vapors emanating from residue in the tank whereby a sufficient amount of the vapors are absorbed into the vulcanized rubber particles to ensure that the hydrocarbon vapor/air ratio is below the explosive envelop.
