The recycling of polypropylene recovered from waste discarded by a composting plant was investigated. recovery involved sorting step carried out means an optical infrared separator and subsequent washing treatment. This method processing allowed us to obtain that only slightly contaminated other polymeric inorganic materials. As many tens tons could be every year in this plant, convenient the e...

This study investigated the performance of recycled polypropylene (RPP)/peanut shell powder (PSP) composites with untreated PSP and treated PSP with alkaline peroxide. The RPP/PSP and RPP/PSPH2O2 composites were prepared by melt mixing and compression molding at different PSP loadings (10 wt.% to 40 wt.%). The samples were characterized by processing properties, tensile properties, Fourier tran...

Leaf and stem fibers of Sorghum halepense L. (SH) were investigated as fillers for recycled polypropylene (RPP) at 10, 20, 30 wt%. The effects SH in RPP on the thermal mechanical properties composites by tensile bending tests, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC). It was found that decreased but their elasticity modulus increased. addition to polymer matrix ...
