Abstract
Purpose: This study performs a systematic review through a global analysis of selected articles on food waste and the Circular Economy in the period between 2011 and 2020, indexed in the Scopus and Web of Science databases. Methodology/Approach: It performs a qualitative analysis of 19 selected articles to identify how the Circular Economy can be used in the strategy to reduce food waste. Findings: The main focus is to avoid a global collapse, provoked by the unrestrained increase in production and consumption since the industrial revolution, intensified in the middle of the 20th century. That culminated in the degradation of the soil, seas and the consequent air pollution caused by all these factors, and in the social issue, the increase in social inequality between countries and people, and the evolution of food insecurity, especially among the most vulnerable. Research Limitation/implication: This research contributes to academia and society, by identifying principal authors, keywords, and gaps in the selected literature and then, proposes suggestions for future research. Originality/Value of paper: The growing waste of food has directly affected the economic, social and environmental spheres, a subject widely discussed and included in the Sustainable Development goals of 2030.

An analysis will be proposed based on Lotka's law of research productivity, where the author came to the conclusion that the concentration of scientific knowledge came from a small part of the authors and Zipf's law of word frequency, which identifies the use of a word repeatedly in a scientific paper, and these most used words elucidate the topic addressed in the research
Summary
One third of food produced for consumption is discarded each year worldwide (FAO, 2021) Such a waste constitutes a serious threat to food security, the economy and the environment (Abiad & Meho, 2018). Due to the risk to sustainability in its various aspects, food waste is an issue that is reflected in the 2030 Sustainable Development agenda and is portrayed in goal 12.3 of the Sustainable Development Goals (SDGs). This goal foresees a halving of the waste generated by food waste by 2030 (FAO, 2019). The current economics model is considered a linear model, which consists of “producing, using and disposing” (Lehtokunnas et al, 2020)
