“…Besides, similar to previous studies (Principato et al, 2021) our research sheds light on the complex sides of the food waste phenomenon, highlighting the trend of research on this topic (Zhang et al, 2018;Vásquez Neyra et al, 2022;D'Adamo et al, 2023). More specifically, our study provides an essential segment of information presenting the issues around food waste that are denoted as the motor themes with a critical role of food waste in future food waste management and policies, such as the concept of circular economy (de Oliveira et al, 2021;Nikolaou and Tsagarakis, 2021;Santagata et al, 2021).…”

The present study investigates the relationship between food waste and sustainable development, aiming to reveal contextual insights and present novel findings regarding the pivotal importance of waste and environmental strategies toward a circular economy. This research represents an effort to delineate methodological and thematic contributions, thoroughly analyze key themes, examine co-citation patterns, assess collaboration among countries, and identify current knowledge gaps in the literature. As waste management takes precedence within the framework of sustainable development goals, policymakers, and academia will better understand how effective food waste management can contribute to environmental sustainability. Methodologically, we employ systematic review, employing the PRISMA approach, analyzing 761 final papers, and investigating the relationship between food waste and sustainable development. We delve deeper to reveal contextual insights and present empirical findings that underscore the critical role of food waste in the economy and environment. Furthermore, guided by the identified knowledge gaps, we illuminate potential future research avenues that hold immense promise for advancing our understanding of food waste and its impact on sustainable development.

“…The yield product per biomass (Y p/x ) [Equation ( 1)] and product per substrate (Y p/s ) [Equation (2)] were calculated at maximum surfactin and fengycin concentrations. The yield biomass per substrate (Y x/s ) [Equation (3)] and specific growth rate (µ) [Equation ( 4)] were calculated at a maximum cell dry weight (CDW).…”

“…Due to rapid population growth and urbanization, coupled with industrial development and changing lifestyles, food waste (FW) is now a global challenge [1]. Food waste, as defined by the Food and Agriculture Organization (FAO), refers to food fit for human consumption that has been discarded, regardless of whether it has passed its sell-by date or has deteriorated [2]. Approaching the issue of food waste, the problem lies not only on an economic and ethical level but also on an environmental level [3].…”

In a scenario of increasing alarm about food waste due to rapid urbanization, population growth and lifestyle changes, this study aims to explore the valorization of waste from the retail sector as potential substrates for the biotechnological production of biosurfactants. With a perspective of increasingly contributing to the realization of the circular bioeconomy, a vegetable juice, derived from unsold fruits and vegetables, as a carbon source was used to produce lipopeptides such as surfactin and fengycin. The results from the shake flask cultivations revealed that different concentrations of vegetable juice could effectively serve as carbon sources and that the fed-batch bioreactor cultivation strategy allowed the yields of lipopeptides to be significantly increased. In particular, the product/substrate yield of 0.09 g/g for surfactin and 0.85 mg/g for fengycin was obtained with maximum concentrations of 2.77 g/L and 27.53 mg/L after 16 h, respectively. To conclude, this study provides the successful fed-batch cultivation of B. subtilis using waste product as the carbon source to produce secondary metabolites. Therefore, the consumption of agricultural product wastes might be a promising source for producing valuable metabolites which have promising application potential to be used in several fields of biological controls of fungal diseases.

“…A study by [62] has already shown that moving to a target-efficient system would reduce freshwater eutrophication, acidification, and nonrenewable energy depletion in Irish dairy. As more consumers become more responsible for their purchasing behaviour by purchasing environmentally friendly products [59,60], and reducing food waste and losses, this case study shows that there are potential positive ripple effects of holistic sustainable production [69]. Such solutions are important to achieve all three dimensions of environmental, economic and social sustainability [69].…”

Agriculture in Ireland is responsible for producing and exporting healthy, nutritional food pivotal for meeting the Sustainable Development Goals (SDGs) such as global food security, economic development and sustainable communities. However, the agricultural sector, dominated by a large bovine population, faces the challenge of reducing greenhouse gas (GHG) emissions to reach climate neutrality by 2050. The objective of the current study was to model the environmental and economic impact of simultaneously applying farm-level climate change mitigation strategies for a conventional grass-based dairy farm in Ireland. An average farm of 52 ha with a spring-calving herd of 93 was used as a reference scenario to create a business case. Partial budgeting was used to calculate the annual net benefit. A cradle-to-grave life cycle assessment (LCA) was used to model the reduction in GHG emissions, which was expressed as kg of carbon dioxide equivalent per kilogram of fat- and protein-corrected milk (kg CO2-eq/kg FPCM). The baseline for average emissions was 0.960 kg CO2-eq/kg FPCM. An average farm would reduce its annual emissions by 12% to 0.847 kg CO2-eq/kg FPCM in Scenario 1, where climate change mitigation strategies were applied on a minimal scale. For Scenario 2, the emissions are reduced by 36% to 0.614 kg CO2-eq/kg FPCM. In terms of annual savings on cash income, an increase of EUR 6634 and EUR 18,045 in net savings for the farm are realised in Scenarios 1 and 2, respectively. The business case provides evidence that farms can move towards climate neutrality while still remaining economically sustainable.
