Antonyms are words with opposite meanings to a given word, and for "repurpose," the antonyms can be "destroy," "throw away," "waste," or "discard." These words mean to dispose of something without considering how it can be used again or differently. Unlike "repurpose," which means to find a new and creative way to use something, these antonyms convey a lack of appreciation for the resourcefulness of repurposing. The benefits of repurposing include conserving resources, reducing waste, and minimizing environmental effects. Therefore, it is essential to consider repurposing before resorting to the antonyms mentioned above.
