Pathways to Carbon Neutrality: A Review of Life Cycle Assessment-Based Waste Tire Recycling Technologies and Future Trends

Processes, Journal Year: 2025, Volume and Issue: 13(3), P. 741 - 741

Published: March 4, 2025

Waste tires (WTs) pose significant environmental challenges due to their massive volume, with millions of tons generated globally each year. Improper disposal methods, such as illegal burning, further aggravate these issues by releasing substantial quantities greenhouse gases (GHGs) and toxic pollutants into the atmosphere. To mitigate impacts, adoption environmentally friendly resource recovery technologies a thorough evaluation benefits are crucial. Against this backdrop, research reviews life cycle assessment (LCA)-based analyses WT recycling technologies, focusing on performance contributions GHG emission reduction. Key pathways, including pyrolysis, rubber reclaiming, energy recovery, evaluated in terms carbon emissions, alongside an in-depth analysis reduction opportunities across various stages process. Based findings, paper proposes feasible recommendations identifies future trends for advancing recovery. The objectives (1) systematically review existing LCA findings technological pathways recovery; (2) evaluate advantages disadvantages current from perspective reduction; (3) explore trends, proposing optimization development.

Abstract Rubber exhibits excellent mechanical properties after cross‐linking, which provides a strong foundation for its application across various fields. However, the intricate cross‐linked network structure significantly impairs reprocessing capabilities of rubber materials, thereby posing difficulties their recycling. To overcome this challenge, we utilize twin‐screw extruder devulcanization‐grafting modification waste ethylene propylene diene monomer (EPDM), facilitating large‐scale recycling and processing while simultaneously maximizing performance reclaimed rubber. Under thermal shear, desulfurizing agent zinc diethyl dithiocarbamate (ZDC) reacts with cross‐linking bonds (SS, CS) in rubber, leading to scission chains subsequent opening rubber's network. Simultaneously, graft maleic anhydride (MAH) introduces new functional groups (OH/COOH), can improve performance. Compared devulcanization modified alone, exhibited better tensile modulus, strength (12.02 MPa), tear (29.91 kN/m). Furthermore, recycled was comparable that original By adopting technology, challenges environmental pollution resource caused by accumulation be effectively addressed, providing solution sustainable utilization Highlights Mechanical‐chemical recover large quantities (EPDM). Zinc opens EPDM enable degradation. Maleic during enhances properties. Tensile reaches 100%
