The mandatory federal purchasing initiative is a cornerstone of the BioPreferred Program, driven by federal law, the Federal Acquisition Regulation, and Presidential Executive Orders. This initiative requires all federal agencies and their contractors to procure biobased products within certain categories identified by the USDA. Currently, there are 139 product categories, such as cleaners, carpet, lubricants, and paints, each with specified minimum biobased content requirements. This initiative not only sets a precedent for sustainability within government operations but also provides a steady market for producers of biobased goods. To facilitate compliance, the BioPreferred Program offers a range of resources, including the BioPreferred Catalog, which lists all eligible products, and training tools that ensure federal buyers and contractors are well-equipped to fulfill these requirements.
