ASABE Presentation under the theme Transforming Food and Agriculture to Circular Systems

When circularity becomes central to our global food security agenda: Concepts to implementation readiness in rice value chain.

Rice is not only the most common cereal in the world, but it is also the staple food for about half the world’s population. Its production has grown over the years, however, the effective utilization and exploitation of its associated by-products (straw, husk, and bran), remains a challenge. Although fractions of the waste are used as animal feed and bedding, a large portion is burnt with serious economic and environmental implications (such as carbon emissions, air pollution, loss of soil moisture,). The production and consumption of cereals, including rice, have been predicted to increase significantly by the year 2050, with an estimated value of 3 billion tons. This will come with a corresponding increase in rice by-products, thus finding utilization pathways is very crucial. From a circularity viewpoint, there is an opportunity to make rice by-products use an integral part of the global food system and food security strategies. This is particularly essential in low resource settings because of the socioeconomic benefits. In this presentation, we will explore rice husk utilization as a pathway to drive circularity in food security strategies, demonstrating some of the successful concepts applied in low resource setting communities, and how they could be adapted for mainstreaming circularity in our current food system agenda.
