Resources Conservation and Recycling, Journal Year: 2023, Volume and Issue: 199, P. 107255 - 107255

Published: Nov. 3, 2023

End-of-life tyres (ELTs) are difficult to recycle due their complex composition. Although there several possible pathways manage ELTs, in Germany roughly 50 % of the ELTs still incinerated. One emerging technology that promises recycling is thermochemical processing through pyrolysis. This enables recover carbon black and pyrolysis oil can be reused for new tyres. Therefore, this study presents a comprehensive life cycle assessment compare environmental impacts from against current dominant alternative end-of-life treatment pathways. The investigated (i) incineration cement plant, (ii) dedicated (iii) production infills artificial turfs. results show material recovery has lower categories global warming, particulate matter resource use compared target energy recovery.

Application of Waste Tire in Construction: A Road Towards Sustainability and Circular Economy

Published: March 13, 2024

The global demand for rubber is on a steady rise, which driven by the increasing production of automobiles and growing need industrial, medical, household products. This surge in has led to significant increase waste, posing major environmental challenge. End-of-life tire (ELT) primary source possesses hazards due its massive stockpiles. While landfilling low-cost easy-to-implement solution, it now largely prohibited concerns. Recently, ELT waste garnered considerable attention potential applications civil engineering construction. These not only enhance sustainability but also foster circular economy between construction sectors. review article concentrates recent research progress challenges waste. It discusses commercially available recycled rubber-based materials, their properties, testing standards, certification. To best authors' knowledge, this first time such discussion commercial products been presented.

Strategies for compatibilization of polymer/waste tire rubber systems prepared via melt-blending

Advanced Industrial and Engineering Polymer Research, Journal Year: 2023, Volume and Issue: 7(4), P. 466 - 481

Published: Aug. 8, 2023

Waste tires are a low-cost and high-calorific alternative fuel, therefore energy recovery is still very popular method of their utilization. On the other hand, waste composed from high quality components can be considered as valuable source raw materials. Recent trends showed that further development tire recycling technologies rubber based materials crucial to design cradle-to-cradle loops for elastomer products. This approach fits circular economy concept, however content in various polymer blends or composites usually results deterioration processing and/or performance properties. Some those technological issues resolved by choose suitable compatibilization method. work summarizes recent advances strategies dedicated polymer/waste systems prepared via simple melt-blending, including: i) optimization conditions; ii) GTR particle size oxidation; iii) devulcanization/reclaiming; iv) reactive blending v) methods. Furthermore, limitations challenges related thermoplastic elastomers on also highlighted.

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

Polymers, Journal Year: 2025, Volume and Issue: 17(3), P. 285 - 285

Published: Jan. 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.
