Since the transition to a circular economy (CE) in various sectors is a priority strategic goal of policy planning in the European Union (EU), the goal of this article is to reveal the principles of the CE in the food sector. To achieve the goal, the study is based on a systematic literature review using the literature synthesis and analysis method and the PRISMA 2020 approach for the selection of appropriate literature. From 25 articles, which were selected from the SCOPUS database, 20 were left for final analysis. Based on the literature review, it was discovered that the main principles of the CE in the food sector are management of resources and waste, emission control, natural and production resource sustainability, increase in energy efficiency, reduction and prevention of food waste, recycling and reuse of food waste and public involvement in the transition to the CE. The determination of CE principles in the food sector is the basis for choosing goals and a right strategy for the implementation of CE principles in practice in this area

“…Reduction of food loss and waste is a serious challenge in India, which needs to feed its rapidly growing population (1.7 billion by 2050) [ 9 ]. In order to alleviate the environmental burden that is caused by FW, alternative methods are required to repurpose FW into uses with a higher value [ 10 , 11 ]. This will minimize the impact that FW has on the environment and promote the long-term sustainability of our system of obtaining food [ 12 ].…”

The growing population and healthy food demands have led to a rise in food waste generation, causing severe environmental and economic impacts. However, food waste (FW) can be converted into sustainable animal feed, reducing waste disposal and providing an alternative protein source for animals. The utilization of FW as animal feed presents a solution that not only tackles challenges pertaining to FW management and food security but also lessens the demand for the development of traditional feed, which is an endeavour that is both resource and environmentally intensive in nature. Moreover, this approach can also contribute to the circular economy by creating a closed-loop system that reduces the use of natural resources and minimizes environmental pollution. Therefore, this review discusses the characteristics and types of FW, as well as advanced treatment methods that can be used to recycle FW into high-quality animal feed and its limitations, as well as the benefits and drawbacks of using FW as animal feed. Finally, the review concludes that utilization of FW as animal feed can provide a sustainable solution for FW management, food security, preserving resources, reducing environmental impacts, and contributing to the circular bioeconomy.

“…From a sustainability point of view, the use of biomass-derived building blocks constitutes a great advantage of substituting non-renewable fossil-based ones. Biomasses are carbonaceous sources and are often obtained as by-products from the agroindustry, and in many cases, end up becoming a waste [32][33][34][35]. It is estimated that around 200 billion tons of biomass is produced annually and only 3% is exploited [35].…”

“…For this reason, an increasing number of studies are in progress to valorise bio-waste, which is an extraordinary reservoir of carbon and represents a valid alternative to traditional fossil-based sources. To date, biomass cannot completely substitute fossil-based products, but it can nevertheless contribute to the transition towards an eco-sustainable future [32][33][34][35].…”

The one-pot alkoxycarbonylation of halo-free alkylaryl and furanyl alcohols represents a sustainable alternative for the synthesis of alkylaryl and furanyl acetates. In this paper, the reaction between benzyl alcohol, chosen as a model substrate, CH3OH and CO was tested in the presence of a homogeneous palladium catalyst, an activator (isopropenyl acetate (IPAc) or dimethyl carbonate (DMC)) and a base (Cs2CO3). The influence of various reaction parameters such as the CO pressure, ligand and palladium precursor employed, mmol% catalyst load, temperature and time were investigated. The results demonstrate that decreasing the CO pressure from 50 bar to 5 bar at 130 °C for 18 h increases yields in benzyl acetate from 36% to over 98%. Further experiments were performed in the presence of piperonyl and furfuryl alcohol, interesting substrates employed for the synthesis of various fine chemicals. Moreover, furfuryl alcohol is a lignocellulosic-derived building block employed for the synthesis of functionalized furans such as 2-alkylfurfuryl acetates. Both the alcohols were successfully transformed in the corresponding acetate (yields above 96%) in rather mild reaction conditions (5–0.01 mol% catalyst, 5–2 bar CO pressure, 130 °C, 4–18h), demonstrating that the alkoxycarbonylation of alcohols represents a promising sustainable alternative to more impactful industrial practices adopted to date for the synthesis of alkylaryl and furfuryl acetates.
