SUSTAINABILITY 64 FEED & ADDITIVE MAGAZINE February 2025 tion, they also carry a low carbon footprint. The PEFCR Feed for Food-Producing Animals is the methodology that describes how the footprint in compound feed production should be measured. The footprint of a feed material is underpinned by economic allocation. This means that the (very) low economic value of former foodstuffs sold as feed compared to their value on the food market is translated into a low footprint. The EFFPA members BFAN (Germany), UKFFPA (UK) and VIDO (NL) have successfully submitted datasets on the footprint of several processed former foodstuff products to the GFLI Database, which is the global reference for carbon and environmental footprint data on commonly used feed ingredients. Operators with access to the GFLI database can use these datasets in their feed formulation strategies to assess the reduction impact when replacing nutritionally equivalent feed ingredients (typically a grain like wheat or maize, plus a fat-based ingredient like palm oil) with processed former foodstuffs and use processed former foodstuffs as part of the strategy to reduce the carbon footprint of feed and livestock production. A KEY EXAMPLE OF CIRCULAR FEED In the European feed industry, the use of "circular feed" is identified as a key performance indicator for the industry's commitment to sustainability. By ensuring that residual materials are reintegrated into the food chain rather than discarded as waste, circular feed practices promote a more sustainable and efficient system, enhancing the overall circularity of food production. FEFAC, representing the European Feed Manufacturers’ Association, made a publication in 2022 on Circular Feed, describing the conceptual approach and providing a large range of examples. Former foodstuffs are one of the circular feed examples mentioned. In addition, the use of former foodstuffs in feed is a means to prevent food waste at food manufacturer and retail level. Circular feed, including former foodstuffs, has the potential to be a key driver of more sustainGlobal warming potential (CO2 equivalents) Kg CO2 / ton ingredient Wheat grain Barley grain Maize Oat husk meal Soybean meal Potato protein Pig feed compound (NLaverage) Dry products to be unpacked (with inputs) Dry products to be unpacked (no inputs) Liquid streams Products to be dried
