Abstract
Until now, recycling studies brought to the agenda after the rapid increasing of plastic materials in every area and causing those plastics to environmental pollution after discarding them following the utilization. The purpose of recycling plastic waste is to minimize environmental pollution and to create of new resources. To perform the present study, Recycled Polypropylene Granules (RPP) belonging to Polypropylene (PP) will be used in most particularly in the automotive and in the packaging industry finding application area behind the Low Density Polyethylene (LDPE). To develop the several properties (physical and thermal) of RPP polymer and to get close to or greater value to the original PP features, different rates of micron-sized glass fibers, talc and CaCO3 are added into the polymer. By recycling waste, demand for natural resources (such as oil, which is plastic’s raw materials) will decrease and rapid consumption of energy sources will be prevented while providing the protection of natural resources. Raw materials imports would be reduced due to the usage of recycled products. In this study, Recycled Polypropylene Granules (RPP) were obtained from companies and glass fiber/talc/CaCO3 additive RPP granules in different ratios were produced with compounding extrusion process. These produced new composite pellets were produced in injection molding machine by means of designed mold to perform tensile and impact tests. In the thermal analysis, the melting temperature and crystallization rate were determined by DSC analysis; the thermal decomposition temperature was determined by TGA analysis. Micro structural examination was done using a Scanning Electron Microscope (SEM).
Highlights
Environmental alarming has led to a renovated concern in usual materials and problems like recyclability and ecological care are happening gradually significant for the initiation of novel materials and artifacts (Arbelaiz et al, 2005)
Similar results for glass fiber and wood flour were obtained from recycled polypropylene reinforced hybrid composites (AlMaadeed et al, 2012)
Differential Scanning Calorimetry (DSC) Analysis Results In Table 1, the DSC analysis results are given for the samples of Recycled Polypropylene Granules (RPP) polymer, RPP+30% talc, RPP+30% CaCO3 and RPP+30% GF polymer composites
Summary
Environmental alarming has led to a renovated concern in usual materials and problems like recyclability and ecological care are happening gradually significant for the initiation of novel materials and artifacts (Arbelaiz et al, 2005). Plastic recycling has been effectively applied with main treated materials causing in economic profits (Da Costa et al, 2007). Recycled PP is obtainable as a trash material and generates many ecological harms. To decrease the ecological harms, PP can be reprocessed to fabricate new value added artifact with little fabrication price (AlMaadeed et al, 2012). Due to its decent mach inability, excessive recyclability and little price, PP has been noticed a wide range of claims in the textile, packaging, car and furniture productions. To enlarge the variety of claims, growing the strength and modulus of PP has revived significant concern. Discharging PP with hard inert specks is an operative, inexpensive and suitable method to increase the strength and stiffness (Zheng et al, 2009)
