Special Issue Information

Dear Colleagues,

Rubber has great importance in the industrial field, especially for cars (as tires), and many other important applications which vary greatly in scope. This Special Issue will analyze new techniques and strategies for treating, recycling, valuing, and reusing rubber waste. The aim is to provide a broad overview of these new techniques and strategies, and to evaluate the results of these techniques in order to give a second life to these rubbers once they have served their primary use. This Special Issue will provide a scientific perspective of these strategies to enable the reuse, valorization, and recycling of waste rubber. Once their useful life has come to an end, rubber materials may present difficulties for reuse or recycling. In 2017, 13% of US tires were sold in the used tire market after serving their primary use. Of the tires that were scrapped, 43% were burnt as tire-derived fuel, with cement manufacturing being its largest application, while 25% were used to make ground rubber, 8% were used in civil engineering projects, 17% were disposed of in landfills, and 8% had other uses. Hence, a topic of interest for this Special Issue is the analysis of aspects related to the application of new techniques or new uses, in addition to attempts to recycle, reuse, or other proposals that deal with waste rubber.

After the success of the previous Special Issue, entitled “Recycling of Rubber Waste ”, we are pleased to invite researchers to contribute to this second Special Issue. This Special Issue will focus on new treatments or uses for waste rubber and will explore the recycling, reuse, and valorization of waste rubber.

Dumped non-biodegradable tires present a significant environmental threat, with overflowing landfills and associated health risks highlighting the urgency of tire waste disposal. Current disposal methods, such as stacking tires in open spaces, exacerbate the problem. The large-scale recycling of tire rubber waste offers environmental benefits. This study examines the effects of pre-treatment using NaOH and micro-silica as a mineral admixture on the mechanical strength of crumb rubber concrete (CRC) with partial replacement of natural sand. Samples of M20 and M30 grade were prepared with varying levels of crumb rubber (CR) replacement and evaluated at 28 days. CRC prepared with pre-treated NaOH solution and micro-silica showed improved workability and strength compared to conventional concrete and untreated CRC, with the highest strength observed for 5% CR replacement using micro-silica. Predictive models and micro-structural analysis validated these findings. Life Cycle Assessment (LCA) using OpenLCA v2.10 software and the ecoinvent database revealed that incorporating micro-silica into CRC did not significantly increase environmental impacts, compared to conventional concrete across different mixes.
