H. G. de  aCo-production of thermoplastic composites with solid residue from enzymatic hydrolysis of recycled paper sludge.h[electronic resource]  c2017  aThe aim of this study is to enhance the use of agro-industrial byproducts and to address the environmental concerns by a novel method of co-production of thermoplastic composites with a solid residue constituting biorefinery. Accordingly, the reuse of 10e30 wt. % solid residues (SRH) from the enzymatic hydrolysis of recycled paper sludge (PS) in the production of thermoplastic composites with polypropylene (PP) was investigated. Thermal properties, water absorption, tensile strength and morphology of the prepared composites were evaluated. Higher thermal stability, rougher and wetter surface, and characteristics of a brittle material were observed in PP-SRH composites in comparison to the pristine PSPP composites and the neat PP. The water absorption increased with increasing amount of SRH, but in lower proportion compared to other common raw materials used in the preparation of composites. Use of SRH resulted in similar or better properties compared to the composites made with the unhydrolyzed paper sludge, suggesting that SRH has potential for recycling and utilization as filler in the development of thermoplastic composites.  aComposite materials  aPulp and paper sludge  aThermal stability  aWettability  aResíduo Solido  aCompósito termoplástico  aEstabilidade térmica  aMolhabilidade  aPaper mill sludge  aResource efficiency  aSolid residue1 aCLARO, F.
