The rapid growth of scrap tires worldwide has called for many environmentally friendly recommendations to reuse them both in land and marine environments. In marine, for instance, scrap tires could be used as wave barriers, floating breakwaters, or artificial reefs. However, identifying the chemical leaching properties of scrap tires is essential to preserve the safety of the marine ecosystem. This research studied the organic and inorganic leaching properties and rates of scrap tire particles (STP) under different marine conditions. The cumulative mass of inorganics (heavy metals) and total organic carbon (TOC) leached from STP in seawater were investigated under different pH conditions. In addition, leached inorganics and TOC were examined under different salinity and temperature levels that reflect typical seawater conditions. The findings of the study provide recommendations and strategies for safe scrap tire-recycling programs in the marine environment.
