“…The use and efficiency of renewable energy in food storage and cooking technology, as well as the new cooking habits, are also relevant drivers of the environmental manage of the supply chain (Caputo et al 2017;Corrado et al 2019;Scherhaufer et al 2018) that are not always considered in agroecological proposals. Finally, it is important to mention the creation of school vegetable gardens and organic matter reuse programs (like the ones implemented in Ames) as contributing not only to closing nutrient cycles but to mitigating GHG emissions (De Sadeleer, Brattebø, and Callewaert 2020).…”

This work evaluates and discusses the greenhouse gas (GHG) emissions reduction potential of agroecological policies implemented in public food procurement for school canteens. Using a life cycle analysis (LCA) methodology (cradle-to-grave approach) and the information gathered from the Red Municipal de Comedores Escolares (Local Network of School Canteens) in the municipality of Ames (A Coruña, Galicia, Spain), the results show how organic production, dietary change (less animal protein), seasonal consumption, and packaging reduction, among other measures, can mitigate the climate impact of school meals. The food policies implemented in Ames have allowed mitigating the GHG emissions of local school canteens by 13.4%. Under realistic conditions, this reduction could rise to 40.6% should the agroecological transformation of the food system continue to advance.

“…The use of mathematical modeling also allows for effective planning of waste management systems and assessment of the impact of changes in input parameters on the functioning of the system as a whole [25][26][27][28][29][30][31][32][33][34][35][36]. It has proved particularly useful in recent years in connection with the implementation of the circular economy concept [37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53]. Obviously, with the implementation of the circular economy concept, municipal waste will not disappear ("zero waste") and its amount will still depend on the standard of living of the inhabitants.…”

Municipal Solid Waste Mass Balance as a Tool for Calculation of the Possibility of Implementing the Circular Economy Concept

Municipal waste management system modeling based on the mass balance of individual waste streams allows us to answer the question of how the system will react to organizational changes, e.g., to the expected reduction in the amount of plastics or the introduction of a deposit for glass and/or plastic packaging. Based on the data on Polish municipal solid waste and the forecast of changes in its quantity and composition, as well as demographic data, a balance model was prepared to assess the impact of introducing higher and higher levels of recycling, in accordance with the circular economy assumptions on the waste management system. It has been shown that, for the Polish composition of municipal waste, even if the assumed recycling levels of individual streams are achieved, achieving the general target level of 65% recycling in 2025/30 may not be feasible. The possibility of achieving a higher level of recycling will be possible due the introduction of selective ash collection from individual home furnaces, while the impact of reducing the amount of plastics or introducing a deposit on packaging is minimal. The calculations also showed that, to complete the waste management system in Poland, we need at least 3.5 million Mg/year of incineration processing capacity and the present state (approx. 1.3 million Mg/year) is insufficient.

“…In addition to optimization tools, there is a need for developing assessment tools to analyze and predict the impacts of various action plans on the circularity of MSW management. Sadeleer et al [15] integrated a material flow analysis (MFA) considering the downstream system with published LCA results for the upstream system to investigate the environmental impacts of two waste management systems for household organic food waste, namely recycling by anaerobic digestion (AD) and incineration. To analyze the impact of changes related to waste management system structure, Tomic et al [35] was adjusted and used a time-dependent LCA based waste, material, and energy flow tracking framework to calculate material and energy production, which can be monetized.…”

Municipal solid waste (MSW) management has emerged as one of the major environmental challenges globally. The consequences of inappropriate waste management are manifold and the trend would continue if immediate interventions are not taken for its reversion amid rapid urbanization and current consumption patterns of individuals. The concept of circular economy (CE) can contribute to a paradigm shift in the transformation of the traditional linear approach that does not favour reuse, recycle, recovery concept. Modern and proven waste management practices with collection systems, recycling facilities, sanitary landfills, and waste-to-energy (WtE) and nutrient recovery offer opportunities to improve urban environment through the valorization of waste and by-products in a CE. This study scrutinizes the existing literature on the assessment of circularity and helps to develop a unified circularity framework in the management of MSW in cities. Key aspects such as tools for measuring circularity, nexus and trade-offs, and conditions in promoting CE are discussed. Finally, this paper elucidates the need for circularity, including enablers and inhibitors for promoting circularity in the management of MSW with a case study in the city of Curitiba, Brazil.
