Item TECHNOLOGY ANALYSIS OF PLASTIC RECYCLING INDUSTRIES & THEIR PERFORMANCE ENHANCEMENT: A CASE STUDY OF KATHMANDU VALLEY(I.O.E. Pulchowk Campus, 2023-10) PANTHI, RIMAThis thesis presents the comprehensive study of the current plastic recycling technologies employed in the industries of Kathmandu valley. The research identified a technological gap that required improvement. To fulfill this gap machines that are being used in plastic recycling industries, with a focus on HDPE, were redesigned as per engineering calculations and then fabricated. Numerical verification of redesigned machines revealed subsequent improvement. It showed that for granulator machine by using the suitable bearing type, the dynamic and static load bearing capacity was increased by 2.13 times and 2.64 times respectively compared to the existing design. Similarly, for dryer machine, using double support instead of single increased critical loading by 1.48 times and combined loading decreased by 1.63 times. Likewise, the mixture machine also achieved significant enhancement, with critical loading increased by 2.53 times and combined loading decreased by 2.95 times.
