Porous rubber tubing (PRT) derived from scrap tire has traditionally been used solely for microirrigation.
In this study, we demonstrate that PRT can be used as an alternative, durable membrane material which has potential for use in a variety of water and wastewater filtration applications. The life cycle analysis (LCA) for using scrap tire derived PRT for water filtration was also quantified by examining its manufacturing procedure. Two methods of crumb rubber production – mechanical and cryogenic – were evaluated. A final brief market analysis suggests that PRT has a favorable potential for creating a new product market and at the same time diverting scrap tires from landfills.
