ABSTRACT=<p>The feed-food competition for environmental and economic resources raises increasing concerns about the production and supply of protein for the global livestock sector. Risks to food-security and approaching deadlines for global sustainable development, means exploring alternative protein feed ingredients is imperative. This <italic>Review</italic> discusses the potential for soilless, local and circular protein feed sources to provide solutions for key sustainability and food-security threats to the global livestock sector, through their partial incorporation in future livestock feeds and feeding systems. In doing so, it offers a holistic insight into the potential opportunities, but also risks associated with such alternatives. Through this analysis, a four-point strategic plan is synthesized to facilitate higher-level policy making that may enable implementation of these alternative ingredients at commercial scales, building toward a more sustainable and resilient livestock industry.</p>
