2021 Asphalt Rubber Summit

July 8 @ 9:00 am - 12:00 pm

Waste management on islands can be challenging because of the limited landfill capacity, high energy costs, limited recycling options, and other hurdles. With over 3 million waste tires annually, Puerto Rico is one such example. Improperly disposed waste tires retain water and facilitate the breeding of mosquitoes which spread infectious diseases, posing a health hazard.

Puerto Rican waste tires are typically exported for energy recovery. However, because their amount is vast, the interest in local recycling and reuse is increasing. Recycled tires can be pulverized into ground tire rubber (GTR) modifier for asphalt pavements. GTR asphalt has been successfully used states such as California, Arizona, and Florida. In Puerto Rico, GTR-modified pavements can potentially alleviate waste tire streams. However, potential waste management policies should include the quantification of environmental impacts to ensure environmental benefits and identify potential tradeoffs.

To learn more about waste tire management solutions for Puerto Rico and how data-driven decision-making can inform local efforts, join Asphalt Rubber Summit on July 8th from 9 am to noon ET. Sustainable Pavements Program will present a life cycle assessment (LCA) study on the environmental impacts of GTR-modified pavements in Puerto Rico and the impacts of different waste management practices on a system level.
