The "Biomanufacturing and Jobs Act of 2025" seeks to significantly improve the existing biobased markets program, recognizing the value of biobased products in supporting agriculture, reducing petroleum reliance, and fostering rural economic development. Its core purposes include supporting domestic manufacturing of biobased products from agricultural commodities, expanding the Department of Agriculture's role in promotion, and increasing federal purchasing of these items. The bill aims to strengthen the biobased products industry and make a national commitment to rural and agricultural economies. A key provision of the bill is the expansion of definitions to include terms like "bio-attributed plastic," "bio-attributed product," and "bioproduct," broadening the scope of products covered by the program. It strengthens federal procurement requirements by mandating that agencies annually increase biobased-only contracts or the volume purchased, and issue guidance to consider product lifespan, savings, and efficacy in procurement decisions. The bill also requires the establishment of price premiums for different types of biobased products to encourage their adoption. To enhance transparency and compliance, the legislation streamlines reporting requirements for procuring agencies, focusing on their biobased procurement actions and reasons for any unmet targets. The Office of Federal Procurement Policy, in coordination with the Secretary, will annually collect, verify, and publicly release this information. Furthermore, it mandates training for federal agency staff on biobased product purchasing and requires updates to federal online procurement systems, such as GSA Advantage! and FedMall, to designate and track biobased products effectively. The bill improves the BioPreferred labeling initiative by requiring the Secretary to inform the public on how to report unauthorized label use and authorizing public marketing and education efforts, including outreach to small businesses and public-private partnerships. It allows the Department of Agriculture to accept non-Federal contributions for these marketing activities and mandates annual reports on labeled products and marketing plans. The program's authorization is extended until 2031, and specific standards for determining biobased content are established, requiring stakeholder input for alternative standards. To ensure coordinated efforts, the Act establishes a Biobased Task Force within the Department of Agriculture, comprising representatives from various mission areas. This task force is charged with coordinating, maximizing resources, and evaluating the effectiveness of biobased product programs, ultimately providing recommendations for improvements. Finally, the bill introduces new regulations prohibiting the unlawful sale or labeling of products using specific "covered terms" if they do not meet the established definitions, while also ensuring the confidentiality of proprietary business information.
