    Study and analyze the properties of recycled plastic waste and compare it with virgin plastic

    Plastic is considered one of the most widely used materials in the world, but it causes a major environmental problem due to its inherent difficulty in decomposing and disintegrating, in addition to its high rates of consumption and production. Due to continued use, plastic may lose some of its properties and thus become less usable for its intended purpose. In this case, it is considered waste and is usually disposed of as waste or burned. The possibility of using plastic waste can be a suitable environmental solution. One such way is to recycle this waste into other products with limited properties. In this work, the characteristics of waste polypropylene (PP Waste) and virgin polypropylene (PP Virgin) were studied and compared. Through the results obtained, we have concluded that polypropylene loses some of its ductility properties, and it also gains some hardness after use.

    Study The Characteristic Of The Effect Of Immersion Duration On Lignocellulosic Fibers Stipa Tenacissima

    The main objective of this work is to provide a better understanding of the effect of the degree (duration) of retting of Stipa Tenacissima stems to control the quality of the lignocellulosic fibers obtained. Once harvested and cleaned of impurities, the stems are immersed in a water bath to trigger their degradation for various periods (14,26,30,45,60 and 90 days). After each targeted period, the stems are brushed manually using a metal brush, washed with distilled water, and steamed at 70°C for 6 hours. A series of analyses is carried out on each series of fibers obtained. Firstly, the densities, crystallinity indices, and chemical characterization of the fibers at each degree of retting are determined and analyzed.
