Application of circular economy principles to livestock production in Vietnam
Global food production is under pressure to produce more from limited resources, with further expectations to reduce waste and pollution and improve social outcomes. Circular economy principles aim to design out waste and pollution, minimise the use of non-renewable external inputs and increase the lifespan of products and materials. Waste sources on Viet Nam livestock farms and options to reduce waste and improve circularity were reviewed. Waste reduction should begin with systems design, while recycling should be at the bottom of the hierarchy. On-farm resource use efficiency has been widely studied, but there are also opportunities to repurpose waste and integrate systems. The use of organic waste products as feed occurs to some extent, but they present both opportunities and challenges. More farm waste recycling opportunities are becoming available, with new products available from waste processing, such as. Circular strategies in Viet Nam livestock require more analysis to determine economic, social, cultural and environmental outcomes.
