The U.S. Department of Agriculture is proposing to add phase change material as a category of biobased products eligible for procurement preference by federal agencies and their contractors.
Phase change material is not currently one of the 109 categories in the USDA's BioPreferred Program. But biobased PCM products are still eligible to participate in the program if they become certified through a voluntary labeling initiative, explained Caroline Tapscott, BioPreferred Program scientist. Products made by three PCM manufacturers – Croda Inc., Phase Change Energy Solutions and PureTemp LLC – qualified for the BioPreferred catalog through that initiative.
The current minimum biobased content for products in such "certification-only" categories is 25 percent. The USDA is proposing to raise the minimum to 71 for phase change materials. All PCM products now listed in the catalog meet that threshold.
The BioPreferred Program was created by the Farm Security and Rural Investment Act of 2002 and expanded by the Food, Conservation, and Energy Act of 2008. The purpose is to increase the use of biobased products.
Under the program, federal agencies are required, with some exceptions, to purchase biobased products within designated product categories when the purchase price of the product exceeds $10,000 or when the quantity of such products or functionally equivalent products purchased over the preceding fiscal year equaled $10,000 or more.
In the document describing the proposed rule changes, the USDA says it "has been unable to obtain data on the amount of phase change materials purchased by federal procuring agencies" but "believes that some federal agencies and their contractors do and would likely purchase these types of products."
The USDA is proposing to add 29 other biobased categories as well, including adhesives, concrete curing agents, exterior paints and facial care products. Public comments on the proposed rule changes will be accepted until Nov. 13, 2018.
