Abstract
AbstractRecycling elastomeric nanocomposites is discussed in view of resource cascading, which aims at maximum exploitation of the value and service time of resources. Special attention is given to particulate releases linked to the elastomeric nanocomposite lifecycle. Recycling of tyres containing, at least partly nanoparticulate, carbon black is discussed as a practical example of the potential for resource cascading, recycling and particulate releases. In the case of elastomeric nanocomposites in general, prevention of degradation and exploring options for self-healing are worth considering in view of resource cascading. Recycling options for elastomeric nanocomposites include: reuse of the product, remanufacturing of the product and use of nanocomposite granulate (where appropriate, devulcanized). Further options are ‘chemical recycling’ (recycling of constituents or conversion products of nanocomposites) and incineration with energy recovery (‘thermal recycling’). Possibilities for the reduction of nanoparticulate releases linked to the elastomeric nanocomposite life cycle and socioeconomic arrangements favoring recycling are briefly outlined.KeywordsCarbon BlackTiO2 NanoparticlesEnergy RecoveryCarbon NanofibersCrumb RubberThese keywords were added by machine and not by the authors.
