Recycling automotive waste has increasingly become an alternative solution towards producing sustainable materials given the rising issue of raw material shortages and waste management challenges at global level. The improper end-of-life vehicle (ELV) waste management poses detrimental impacts on the environment. This paper proposes a novel method to develop thermal insulation sandwich panels using ELV waste, motivated by the critical needs of creating high-performance thermal insulation for buildings. Six sandwich panels (P1-P6) of different weight and ratio of shredded ELV particles were manufactured. The sandwich panels structure was made of three layers: a core, and a glass face sheet bonded to each side. The core structure composed of Polycarbonate (PC) from headlamp lenses and polyurethane (PU) from seat, bonded using resin casting approach. Thermal conductivity of the samples was measured using guarded hot-plate apparatus. Results corroborated that thermal conductivity of ELV-based sandwich panels reduced remarkably compared to panel without ELVs, recorded at 15.51% reduction. Composition gives the best thermal performance was made of mixed ELV core materials of ratio 50%PC:50%PU, it has a thermal conductivity value of 0.1776 W/mK. The transparency data were obtained using Haze-gard plus haze meter. The best luminous transmittance value was exhibited by P2 (100% PC), 67.47%. The best clarity value and haze value were shown by P6 (25% PC: 75% PU), 55.13% and 52.6% respectively. ELV waste can be recycled to develop useful sustainable thermal insulation to improve thermal and optical transparency performance of buildings as a substitute for conventional materials which have a relevance for future façade concepts.

鉴于全球范围内原材料短缺和废物管理挑战日益严重，回收利用汽车废物已日益成为生产可持续材料的替代解决方案。报废车辆（ELV）废物管理不当会对环境造成不利影响。本文提出了一种利用ELV废料开发保温夹芯板的新方法，其动机是为建筑物创建高性能保温材料的关键需求。制造了六块不同重量和比例的切碎ELV颗粒的夹心板（P1-P6）。夹心板结构由三层组成：芯和粘结在每一侧的玻璃面板。前灯透镜的聚碳酸酯（PC）和阀座的聚氨酯（PU）组成的核心结构采用树脂浇铸法粘合。使用防护热板设备测量样品的热导率。结果证实，与不含ELV的面板相比，基于ELV的夹芯板的热导率显着降低，减少了15.51％。由比例为50％PC：50％PU的混合ELV芯材制成的组合物提供了最佳的热性能，其导热系数值为0.1776 W / mK。透明度数据是使用Haze-gard plus雾度计获得的。P2（100％PC）显示出最佳的透光率，为67.47％。P6（25％PC：75％PU），55.13％和52.6％分别显示出最佳的清晰度值和雾度值。
