Mechanical pretreatment is an indispensable process in biological treatment plants that remove plastics and other impurities from household biogenic waste (HBW). However, the imperfect separation of plastics in these pretreatment methods has raised concerns that they pose a secondary formation risk for microplastics (MPs). To validate this presumption, herein, quantities and properties of plastic debris and MPs larger than 50 μm were examined in the full chain of three different pretreatment methods in six plants. These facilities received HBW with or without prior depackaging at the source. The key points in the secondary formation of MPs were identified. Moreover, flux estimates of MPs were released, and an analysis of MPs sources was provided to develop an overview of their fate in HBW pretreatment. Pretreated output can contain a maximum of (1673 ± 279) to (3198 ± 263) MP particles per kilogram of wet weight (particles·kg−1 ww) for those undepackaged at source, and secondary MPs formation is primarily attributed to biomass crushers, biohydrolysis reactors, and rough shredders. Comparatively, HBW depackaged at the source can greatly reduce MPs by 8%–72%, regardless of pretreatment processes. Before pretreatment, 4.6–205.6 million MP particles were present in 100 tonnes of HBW. MPs are produced at a rate of 741.11–33 124.22 billion MP particles annually in anaerobic digester feedstock (ADF). This study demonstrated that HBW pretreatment is a competitive source of MPs and emphasized the importance of implementing municipal solid waste segregation at the source. Furthermore, depackaging biogenic waste at the source is recommended to substantially alleviate the negative effect of pretreatment on MPs formation.

废弃聚对苯二甲酸乙二醇酯(PET)饮料瓶等废弃塑料和废弃橡胶轮胎为主要的城市固体废弃物,如不进行合理回收,可能会引发各种环境问题。本研究对这两种废弃物经综合处理后用作沥青路面性能增强改性剂的可行性进行了分析。通过采用三乙烯四胺(TETA)和乙醇胺(EA)对废弃PET进行处理,分析废弃PET经处理获得添加剂的回收机理,同时表征这两种添加剂在改性橡胶沥青过程中的表现。鉴于此,本文采用红外光谱和热分析法对PET添加剂(PET-TETA和PET-EA)进行了研究,进而通过红外光谱、黏度、动态剪切流变和多次应力蠕变恢复等试验对这两种PET添加剂改性的橡胶沥青进行了分析。结果表明:通过化学处理后,废弃PET可被增值回收为功能性添加剂,以提高橡胶沥青的整体性能。本研究所开发的回收方法不仅有助于缓解废弃PET塑料和废弃轮胎的填埋问题,而且可将这些废弃物转变为耐久性路面建设的高附加值新材料。

分析了经典塑性力学用于岩土类材料的问题,它采用了3个不符合岩土材料变形机制的假设。从固体力学原理直接导出广义塑性位势理论,将经典塑性力学改造为更一般的塑性力学——广义塑性力学。广义塑性力学采用了塑性力学中的分量理论,能反映应力路径转折的影响,并避免了采用正交流动法则所引起的过大剪胀等不合理现象,也不会产生当前非关联流动法则中任意假定塑性势面引起的误差。给出了广义塑性力学的屈服面理论、硬化定律和应力-应变关系,并建立了考虑应力主轴旋转的广义塑性位势理论。屈服条件是状态参数,也是试验参数,只能由试验给出。应用表明,广义塑性力学可作为岩土材料的建模理论,还可应用于诸如极限分析等土力学的诸多领域,具有广阔的应用前景。
