The diploma thesis deals with the design of the plastic bottle crusher, which should work in the conditions of small collection yards. As part of the analysis of the current state of the art, the existing design solutions are described, and a specification sheet for the construction of the machine is further specified. In the next chapter, the thesis describes the theoretical foundations that need to be applied in solving the topic and possible solutions. The practical part contains the design of the crusher in 3D software, also with necessary calculations of important machine parts and drawing documentation. In conclusion, the design of the crusher is evaluated on the technical- economic side.
