Polymeric products such as plastics and rubbers are in widespread use, and the recycling of these polymeric materials has not kept pace with the increased production. There are serious environmental consequences to disposing of waste polymeric materials in landfills or incinerating them. Their low biodegradability makes it unpopular for both large and small industries to recycle them. This study reviews recycling strategies for waste thermoplastic and thermoset materials undertaken by industries and researchers. The primary objective is to review these techniques and identify those that can be applicable to the construction industry. There are three conclusions from this review: (1) Recycling of polymeric waste materials can be helpful to limit landfilled or incinerated waste plastic. (2) Proper selection of a recycling method for waste plastics and rubbers can effectively address the recycling problem without compromising the mechanical properties of the construction material. (3) The majority of the published articles in construction materials research have overlooked the importance of pre-treatment of waste polymeric materials to ensure compatibility with construction materials. Accordingly, there is an urgent need for understanding the science of functionalization of polymers to be able to tune surface properties of the recycled granules for targeted applications. This paper highlights critical research needs to facilitate the recycling of thermosets and thermoplastics to promote resource conservation and sustainability.

塑料和橡胶等聚合物产品得到广泛使用，这些聚合物材料的回收利用并没有跟上产量的增加。在垃圾填埋场处置废弃聚合物材料或将其焚化会产生严重的环境后果。它们的低生物降解性使得大型和小型工业都不欢迎回收它们。本研究回顾了工业和研究人员对废弃热塑性和热固性材料的回收策略。主要目标是审查这些技术并确定可适用于建筑行业的技术。本次审查得出三个结论：（1）聚合物废料的回收利用有助于限制填埋或焚烧的废塑料。(2)合理选择废旧塑料、橡胶的回收利用方式，可以在不影响建筑材料力学性能的前提下，有效解决回收问题。(3) 建筑材料研究发表的大部分文章都忽视了对废弃聚合物材料进行预处理以确保与建筑材料的相容性的重要性。因此，迫切需要了解聚合物官能化的科学，以便能够针对目标应用调整回收颗粒的表面特性。本文强调了促进热固性塑料和热塑性塑料回收利用以促进资源保护和可持续性的关键研究需求。
