MAQOLA ANNOTATSIYASI

quote
This article focuses on analyzing the efficiency of polymer waste recycling and utilization technologies. The study showed that the recycling of polyethylene (PE) and polypropylene (PP) reaches 85% and 78%, respectively, due to their molecular weight and crystallinity, which are suitable for recycling processes. However, the recycling of polyethylene terephthalate (PET) and polystyrene (PS) demonstrates lower efficiency, at 45% and 40%, respectively. The results indicate that to improve recycling efficiency, optimal parameters for temperature (400°C) and time (30 minutes) should be established. The article also emphasizes the importance of implementing environmentally safe recycling technologies for polymer waste
