Etymology
The word compactor is a modern English formation built upon the classical Latin root pangere, meaning "to fasten or drive in." Its past participle stem, pact-, evolved to signify something fixed or agreed upon, giving us the core concept of binding. The prefix com- intensifies this to mean "fasten or press together." When the agent suffix -or is added, it creates a noun for an entity that performs this action of pressing together. Thus, the literal logic of "one who fastens things together" evolved into the modern, specialized meaning of a machine that compresses waste into a denser form.
Analysis

com: Latin origin, a prefix meaning "together, with".
pact: From Latin pactum (something fixed, agreed), from pangere (to fasten, fix). In this word, it carries the sense of pressing or binding together.
or: Latin agent suffix, indicating a person or thing that performs an action.
