The ever-increasing production of plastics reveals the necessity of robust waste recycling technologies, which is critical for environmental sustainabilty and economic prosperity. Not only must these processes be capable of addressing a broad variety of commodity polymers, but they must also produce cost-competitive products to allow for widescale implementation. Conversion of plastic wastes into value-added carbon materials offers a promising upcycling pathway, potentially coupling cost-efficacy with process scalability. This work reviews the current progress in plastics-derived carbons, focusing on common commodity thermoplastics such as polyolefins, polyethylene terephthalate, and polystyrene while also highlighting more complex plastic waste streams, including thermosets, engineering plastics, composites, and mixed wastes. Lastly, a perspective is provided on future research opportunities to further enable the upcycling of plastic wastes to valuable carbonaceous materials.
塑料产量的不断增加凸显了强大的废物回收技术的必要性，这对环境可持续性和经济繁荣至关重要。这些工艺不仅必须能够处理各种各样的商品聚合物，还必须生产具有成本竞争力的产品，以便能够大规模实施。将塑料废物转化为增值碳材料提供了一条有前景的升级循环途径，有可能将成本效益与工艺可扩展性结合起来。本文综述了源自塑料的碳的当前进展，重点关注常见的商品热塑性塑料，如聚烯烃、聚对苯二甲酸乙二酯和聚苯乙烯，同时也强调了更复杂的塑料废物流，包括热固性塑料、工程塑料、复合材料和混合废物。最后，对未来的研究机会提供了一个展望，以进一步推动将塑料废物升级循环为有价值的含碳材料。
