The global challenge of feeding an ever-increasing world population is leading scientists’ attention towards nutritious and sustainable foods whose production should have low impacts on environment, economy and society. In case the input feedstock can be waste nutrients, the label of such productions becomes even greener. Nutrients circularity is nowadays an important circular economy practice. This mini-review focuses on the valorisation of food waste as precious biomass to grow new food and feed. In particular, three functional edibles are discussed in the present paper: mushrooms, microalgae and insects. These foods are part of people diets since ages in certain areas of the world and the original aspect of their cultivation and breeding found on waste nutrients recovery is here reviewed. Proofs of such food waste biorefinery viability are already given by several researches featuring the main traits of a suitable growing medium: optimal pool of nutrients and optimal pH. However, lot of work still needs to be done in order to assess the optimal growth and cultivation conditions and the health security of the harvested/bred edibles. A SWOT factors analysis was performed.

养活不断增长的世界人口所面临的全球挑战正使科学家们将注意力转向营养丰富的可持续食品，这些食品的生产对环境、经济和社会的影响应该很小。如果输入的原料可能是废弃的营养物质，那么此类产品的标签就会变得更加环保。营养素循环是当今重要的循环经济实践。这篇小型评论侧重于将食物垃圾作为宝贵的生物质来种植新食物和饲料的价值。本文特别讨论了三种功能性食品：蘑菇、微藻和昆虫。这些食物是世界某些地区自古以来人们饮食的一部分，这里回顾了它们在废物养分回收方面发现的种植和繁殖的原始方面。几项研究已经证明了这种食物垃圾生物精炼厂的可行性，这些研究具有合适的生长介质的主要特征：最佳营养池和最佳 pH 值。然而，为了评估最佳生长和栽培条件以及收获/培育食用品的健康安全性，仍然需要做很多工作。进行了SWOT因素分析。
