Abstract. Problems with plastic solid waste have been a major increasing problem not only in local towns but in the whole Philippines and traditional PSW shredders have been adequate but there is still a huge room for improvements. This study presents an innovative approach to increasing the thermal efficiency of small scale PSW shredders. Continuously Variable Transmissions (CVTs) have only been exclusively adapted to the automotive industry and in doing so, hinders its advantages to other fields such as solid waste management. As a modern approach to designing, a proof of concept in the form of stress and performance simulation when a CVT is integrated into a PSW shredder is therefore presented in this paper. In addition to the calculations in designing the parts, the CVT PSW shredder assembly is also tested under von-Mises, Soderberg and Goodman criteria for failure in Ansys Mechanical to ensure safe use while under operation and Matlab Simulink is used for performance simulation. After the design process regarding the parts’ dimensions, materials, and other considerations within the scope, the result from performance simulation showed promising results in that the major KPIs fuel consumption and theoretical throughput are better in the model with CVT when compared to the same model using a fixed gear ratio transmission.
