Antonyms for the word "products" are tricky to identify, as this term refers to a broad class of items that can vary significantly in their characteristics and uses. However, one possible antonym for "products" could be "inputs," which describes the materials, resources, or information that are used to create a product. Another antonym could be "waste" or "byproducts," which refer to the unwanted or unusable materials generated during the production process. Finally, "consumption" or "depletion" could be considered an antonym for "products," as they describe the process of using up or reducing the availability of goods or resources.
