In the frame of a circular economy, the maximization of secondary raw-material recovery is necessary to increase the economic and environmental sustainability of landfill mining and reclamation activities. In this paper, the polyethylene-rich plastic fraction recovered from the reclamation of an abandoned industrial landfill (landfill-recovered plastic, LRP) has been characterized through spectroscopic, thermal, morphological, and mechanical analyses. Then, an economically viable valorization and recycling strategy was set up. The effectiveness of this strategy in the enhancement of LRP properties has been demonstrated through morphological and mechanical characterizations.
在循环经济框架下，最大化二次原料回收对于提高垃圾填埋场开采和复垦活动的经济和环境可持续性至关重要。本文通过光谱、热、形态和力学分析对从废弃工业垃圾填埋场复垦中回收的富含聚乙烯的塑料部分（垃圾填埋场回收塑料，LRP）进行了表征。然后，制定了一种经济可行的增值和回收策略。通过形态和力学表征证明了该策略在增强LRP性能方面的有效性。
