![]() ![]() Although food waste in industrialized countries mainly occurs at later stages of the production chain, a considerable amount is also produced during earlier steps due to inadequate collection, storage and cooling methodologies. ![]() The Food Waste Index Report stated that ~931 million tons of food waste were generated in 2019, and Latin America and Europe ranked among the countries with the highest consumer waste rates, accounting for 200 and 180 kg per capita per year, respectively. In 2019, it was estimated that global food loss and waste was about ~1.3 billion tons per year, which corresponds to one-third of the food produced for human consumption. On the other hand, climate changes are the most challenging environmental factor, as it leads to an increase in non-marketable products. The first includes the world’s growing population, the actions of suppliers along the food chain, and the decisions of food service providers or consumers. Currently, the rise of food waste can result from both human and environmental factors. However, although interesting and promising results have been reported in several experimental trials, further investigation is needed, since animal health and meat quality are often given marginal consideration.įood waste is a serious issue around the world due to the negative effects it has on the environment, economy, and society. Although some critical issues were highlighted, the overall data suggest a modern and positive interest in the reuse of agri-food waste as swine feed. In addition, a bibliometric analysis combined with visual and meta-analytical studies on 1047 scientific articles was conducted to understand whether the inclusion of agro-food waste could affect the growth performance of pigs and reduce cholesterol levels in pork. In this review, after summarizing the nutritional values of pork and the importance of its inclusion in human diet, a phylogenetic analysis was conducted to investigate potential differences in the structure and activity of HMGCR, which is a key enzyme in cholesterol metabolism. The European Commission is incentivizing a zero-waste policy by 2025, pushing to find a “second life” for at least the avoidable ones. Due to environmental and human factors, there is a growing amount of agri-food waste worldwide. ![]()
