The disposal of facemasks has become a growing concern due to the increasing volume of healthcare waste and its potential negative impact on the environment. This study aimed to develop a shredder that can effectively dispose facemasks and into raw materials that can be used for other purposes. The shredder was designed with an ultraviolet light (UV-Light) sanitation device and a motor that rotates at a high speed. This allows the shredding of the facemasks into small pieces the smaller pieces go straight to the storage system also called a hopper where a UV-C and UV-A placed to sanitize the shredded facemask. The prototype was tested using three parameters. The throughput was measured by the time it took for each type of facemask to finish the shredding process. The KF94 averaged 2.21 seconds, the 3D facemask averaged 1.44 seconds, and the surgical facemask averaged 2.54 seconds. The second parameter is the size of the facemask, although the facemask has an unwanted smaller bit around 2-mm the average size of the shredded facemask is 2.35 x 1.44-mm. Lastly, the maximum capacity of the prototype is 0.78 kg of shredded facemasks.. The prototype was evaluated by 36 respondents who are experts in the medical field and engineering and was rated 4.66. The prototype was proven functional however, this is only limited to KF94, a 3D facemask, and a surgical facemask, and can process one facemask at a time.
