Presentation Transcript

  1. VARIOUS RUBBER WASTE HANDLING METHODS • Incineration • Pyrolysis • Crushing, grinding, pulverization • Cryogenics • Use of chemicals or steam • Microwave energy • Ultrasonics

  2. OBJECTIVES: • Recycling GRT, rubber wastes and thermosets through devulcanization, decrosslinking, compounding and revulcanization • ADVANTAGES OF ULTRASONICS: • No chemicals involved • Fast devulcanization • Continuous process • Devulcanized rubbers can be revulcanized • Decrosslinked thermosets can be molded
