From elastomer microstructure to thermomechanically damaged nanocomposites: an insight into the parameters influencing the biodegradability of rubbers by natural microbial consortia
Summary
Researchers examined how the complex rubber microstructure of tire and road wear particles—including carbon black, silica, and polymer cross-links—governs resistance to biodegradation by natural microbial consortia, finding that thermomechanical damage during road use alters particle morphology but that TRWP remain largely persistent beyond two years in environmental conditions.
Tire and road wear particles (TRWP) have raised questions about their environmental fate, and there is a particular lack of knowledge regarding their biodegradability. Recent studies suggest their persistence beyond 2 years in soil or water. Conversely, several microbial strains have been show...
