This paper addresses the recycling of an industrial waste of jute (Corchoruscapsularis) and polypropylene fibers from Tapetes São Carlos carpet manufacturer conducted through the manufacture of composite materials and use of polypropylene (PP), a compatibilizer (C), and nano-calcium carbonate (N). The components were mixed in a co-rotational twin-screw extruder and dumbbell-shaped specimens were produced by injection molding. A masterbatch was previously processed for improving N dispersion in the polymer matrix. The composites were exposed to accelerated aging and tested by tensile and contact angle measurements, and evaluated by visual appearance before and after accelerated aging. The morphological evaluation was conducted by scanning electron microscopy (SEM). The processing techniques used provided composites with 50 wt.% waste, good N dispersion, no thermal or mechanical degradation of fibers, and better mechanical properties than pure PP. The presence of industrial waste led to a 135 % improvement in the elastic modulus of PP matrix and decreased deformation at break from 435 % to 5 %.N acted as mechanical reinforcement and decreased wettability. 18 % and 16 % improvements were achieved in the elastic modulus of the matrix when N was incorporated through the masterbatch and by direct extrusion, respectively. The composite processed after the manufacture of the masterbatch and with no compatibilizer showed a 186 % improvement in the elastic modulus of the matrix, lowest wettability, and best average performance under accelerated aging. Accelerated aging promotes a small reduction in stiffness, but a drastic dropping in the elongation of the materials. The composites can potentially be used in several commercial applications due to their properties and processing flexibility, which are relevant from both sustainable and economic viewpoints.

本文探讨了黄麻（Corchoruscapsularis）工业废料的回收利用）和TapetesSãoCarlos地毯制造商的聚丙烯纤维是通过制造复合材料并使用聚丙烯（PP），增容剂（C）和纳米碳酸钙（N）进行的。将这些组分在同向双螺杆挤出机中混合，并通过注射成型生产哑铃状样品。预先处理了母料以改善氮在聚合物基质中的分散。使复合材料经受加速老化，并通过拉伸和接触角测量进行测试，并通过加速老化之前和之后的视觉外观进行评估。通过扫描电子显微镜（SEM）进行形态评价。所使用的加工技术为复合材料提供了50 wt。％的废料，良好的N分散性，纤维没有热降解或机械降解，以及比纯PP更好的机械性能。工业废料的存在使PP基体的弹性模量提高了135％，并将断裂变形从435％降低至5％.N起到了机械增强作用，并降低了润湿性。当通过母料和通过直接挤出掺入N时，基质的弹性模量分别提高了18％和16％。在制造母料后且没有增容剂的情况下加工的复合材料在加速老化下的基质弹性模量提高了186％，润湿性最低，平均性能最佳。加速的老化促进了刚度的小幅下降，但是材料的伸长率却急剧下降。
