ABSTRACT:
The present invention relates to methods of using recycled rubber including recycled rubber from tires to absorb hydrocarbons. The method is particularly applicable to absorbing waste or contaminating hydrocarbons from solid surfaces or particles where hydrocarbons may have been spilt or otherwise have contaminated the surfaces. The methods may also be used for removing spilt hydrocarbons from a liquid such as crude oil spills at sea.
