GAIN Working Paper n°46-Opportunities for repurposing waste products into nutritious foods


Reducing food waste represents an important opportunity for shrinking the environmental footprint of food systems and supporting planetary health – and if this waste can be repurposed into nutritious foods, then it could also be a benefit for nutrition and human health. To understand the opportunities for repurposing waste products or byproducts into foods, this paper presents a rapid analysis based on desk research and key informant interviews. The analysis considers byproducts across four categories: fruit and vegetable residues, seeds and seed residues, other plant byproducts, and animal byproducts. The assessment considered availability, potential uses, consumer acceptability, food safety, nutritional quality, and feasibility.
