This investment began the process of defining the sustainability of U.S. soybeans and soybean meal in a more specific way than has been conducted previously. It made good progress, conducting a comprehensive literature search involving articles with LCA determination of soybeans and soybean meal; obtaining access to soybean and soybean meal databases with existing LCA of feed ingredients; and comprehensive literature searches into the contribution of soybean and
soybean meal to environmental impacts of broilers, layer and swine diets.
