Devulcanization of Waste Tire Rubber via Microwave and Biological Methods: A Review

Polymers, Год журнала: 2025, Номер 17(3), С. 285 - 285

Опубликована: Янв. 22, 2025

This paper presents a thorough literature review on devulcanization methods applied to waste tire rubber: “microwave devulcanization” and “biological desulfurization”. To do so, 80 papers published from the year 1990 2024 in journals with subscription open access status across 12 databases were reviewed. compares efficacy reviews basic concepts, advantages, processes, variable parameters of these two methods. In microwave devulcanization, energy breaks sulfur crosslinks between polymer chains. The latter breakage is mainly enabled by presence carbon black tire, which an excellent absorbent. biological desulfurization, bacteria or fungi convert elemental substances sulfate. general, rubber leads lower crosslink density thus higher degree devulcanization. On one hand, breaking requires significantly shorter time than desulfurization. Crosslink scission occurs throughout sample but only surface Microwave not sensitive additives does require detoxification before other desulfurization since it involves living organisms that may tolerate certain additives.

Abstract Liquid rubber, an environmentally friendly oligomer with low viscosity, exhibits the capability of co‐crosslinking within rubber matrix. In this paper, liquid butadiene (LPBD) is employed to replace plasticizer‐treated distillate aromatic extract (TDAE) in green tread rubber. The results demonstrate superior performance LPBD compared TDAE, particularly terms tensile strength at both high and room temperature, elongation break, rebound properties. Although increase DIN abrasion volume loss factor 60°C relatively smaller, hardness reduced case equal replacement these improvements can be achieved by adjusting crosslink density achieve comparable TDAE plasticizer usage. summary, reduce rolling resistance, improve wet skid offering a promising solution long‐standing issue pollution industry. Highlights Feasibility using instead as Crosslinking matrix improves mechanical properties temperature. Adjustment crosslinked network resistance resistance.
