Polymer recycling is a way to reduce environmental problems caused by polymeric waste accumulation generated from day-to-day applications of polymer materials, such as packaging and construction. The recycling of polymeric waste helps to conserve natural resources because most of the polymer materials are made from oil and gas. This chapter reviews the recent progress on the recycling of rubber based blends and their systems. In addition, the effect of recycling on the properties including mechanical, thermal, rheological and processing behavior of the recycled rubber blends is highlighted in the present chapter.
