The recycling of plastic packaging wastes helps to alleviate the problems of white pollution and resource shortage. It is very necessary to develop high-value conversion technologies for plastic packaging wastes. To our knowledge, carbon materials with excellent properties have been widely used in energy storage, adsorption, water treatment, aerospace and functional packaging, and so on. Waste plastic packaging and biomass materials are excellent precursor materials of carbon materials due to their rich sources and high carbon content. Thus, the conversion from waste plastic packaging and biomass materials to carbon materials attracts much attention. However, closely related reviews are lacking up to now. In this work, the pyrolysis routes of the pyrolysis of plastic packaging wastes and biomass materials for conversion to high-value carbons and the influence factors were analyzed. Additionally, the applications of these obtained carbons were summarized. Furthermore, the limitations of the current pyrolysis technology are put forward and the research prospects are forecasted. Therefore, this review can provide a useful reference and guide for the research on the pyrolysis of plastic packaging wastes and biomass materials and the conversion to high-value carbon.
塑料包装废弃物的回收利用有助于缓解白色污染和资源短缺问题。开发塑料包装废弃物的高值转化技术非常必要。据我们所知，具有优异性能的碳材料已广泛应用于储能、吸附、水处理、航空航天和功能包装等领域。废塑料包装和生物质材料因其来源丰富、碳含量高，是碳材料的优良前驱体材料。因此，从废塑料包装和生物质材料向碳材料的转化备受关注。然而，截至目前缺乏与之密切相关的综述。在这项工作中，分析了塑料包装废弃物和生物质材料热解转化为高值碳的热解途径及影响因素。此外，总结了这些所得碳材料的应用。进而，提出了当前热解技术的局限性并预测了研究前景。因此，本综述可为塑料包装废弃物和生物质材料热解及转化为高值碳的研究提供有益参考和指导。
