The research entailed creating and designing a prototype for recycling shredded plastic waste into high quality pellets for use in different industrial and manufacturing environments. The two main objectives in the research are the creation of a plastic extruder that can be scaled and a method for recycling shredded plastic into a uniform pellet. With predictable characteristics. The prototype was developed to accommodate two types of plastics, namely, PET and PLA. The PID Controller measures and controls temperature, while the Arduino Uno is used to program the system. Experimental runs were carried out to fine- tune the pelletization process concerning parameters such as temperature control, size uniformity, and material integrity.Analyses of the produced pellets' suitability for use in subsequent manufacturing processes revealed that their qualities were on par with or superior to those of commercially available pellets. The outcome for the PET and PLA mixture demonstrates that higher temperatures produce better outcomes; 753 pellet pieces weighing 19.7g were produced at the ideal temperature of roughly 150–155° C. PLAs and PETs also showed high temperature performances; the best yield was 680 pieces weighing 15.4g at 210°C. Functionality, beauty, workability, durability, economy, safety, and salability all had mean evaluation scores of 4.40.with a descriptive rating a very good.

The research sought to create a process of recycling plastic waste into high quality pellets
that can be utilized in different manufacturing and industrial environments. The research
entailed creating and designing a prototype for recycling shredded plastic waste into high
quality pellets for use in different industrial and manufacturing environments. The two
main objectives in the research are the creation of a plastic extruder that can be scaled and
a method for recycling shredded plastic into a uniform pellet. With predictable
characteristics. The prototype was developed to accommodate two types of plastics,
namely, PET and PLA. The PID Controller measures and controls temperature, while the

Arduino Uno is used to program the system. Experimental runs were carried out to fine-
tune the pelletization process concerning parameters such as temperature control, size

uniformity, and material integrity.Analyses of the produced pellets' suitability for use in
subsequent manufacturing processes revealed that their qualities were on par with or
superior to those of commercially available pellets. The outcome for the PET and PLA
mixture demonstrates that higher temperatures produce better outcomes; 753 pellet pieces
weighing 19.7g were produced at the ideal temperature of roughly 150–155° C. PLAs and
PETs also showed high temperature performances; the best yield was 680 pieces weighing
15.4g at 210°C. Functionality, beauty, workability, durability, economy, safety, and
salability all had mean evaluation scores of 4.40.with a descriptive rating a very good. The
results point to the possibility integrating recycling technologies to promote circular
economy principles and build environmental resilience.
