<p>Process for surface activation and/or devulcanisation of sulphur-vulcanised rubber particles. In order to break the sulphur bridges and to reduce the sulphur, the rubber particles are treated in a biotechnological manner in a medium with mesophilic anaerobic and/or optionally anaerobic and/or microaerophilic bacteria and/or with one or more enzyme systems of such bacteria. The thus treated, activated rubber particles show improved vulcanisation properties, in comparison with non-treated rubber particles, a nd permit the production of better quality articles.</p> |
