  • Compositions and methods for the removal of chewing gum residues from substrates
    Patent number: 8455421
    Abstract: This invention relates to methods for removing chewing gum and residues thereof from substrates using chewing gum modifying compositions comprising ionic liquids. In one embodiment, the chewing gum modifying composition may be used together with one or more oxidising reagents. In another embodiment, the chewing gum removal compositions further comprise one or more enzymes and one or more enzyme mediator compounds. The invention further relates to novel ionic liquid and enzyme compositions that are suitable for use in removing chewing gum residues.

  • RECOVERY OF ORGANIC CONTAMINANTS FROM TERRESTRIAL ENVIRONMENTS
    Publication number: 20090270670
    Abstract: The present invention concerns a method for removing organic contaminants from a terrestrial environment, such as soil. The method involves contacting the contaminated soil with a solid polymeric material having an affinity for a target organic contaminant, without the need to add any liquid to the soil to form a slurry and/or without the need for the soil to have a high moisture content. Preferably, the organic contaminants absorbed into the polymer materials are removed from the polymer and the polymer reused.
