“…The analysis of these variables in a holistic way was focused on in these studies (Rosa et al , 2019; Sacchi Homrich et al , 2017; Stahel, 2010; Urbinati et al , 2017). Others focused on variants of this philosophy: recycle, reuse, repair remanufacture (4R) (Carpenter et al , 2018; Cooper et al , 2017), sustainability and sustainable (Godoi Gonzalez, 2013; Prieto-Sandoval et al , 2017), ecology (Stahel and Reday, 1976), the production of goods and services from waste of raw materials (Saavedra et al , 2017), the cycle of nature and production (Fang et al , 2017), the economic circle (efficiency and profitability), alternative energy, waste and water, the closed cycle value chain (Yang et al , 2019), business models, water and waste systems (Ferreira et al , 2017), innovation and environmental impacts (Shen et al , 2020), gas emission, change in customer perspective, added value to products and services (García-Alcaraz et al , 2020), sustainable markets, natural resources, culture and ways of learning (Moktadir et al , 2018) and reverse and green logistics (Wang et al , 2018).…”

PurposeIn this paper, the authors adopt the theory of the circular economy to study the transitions that take place in three case studies in Mexico and Ecuador. The work is aimed to systematize a circular economy assessment tool that fosters opportunities for improvement in business practices.Design/methodology/approachThe methodology is based on a descriptive quantitative analysis, where a checklist is made with 91 items and nine study variables. This is from the study of the bibliography and business practice. Furthermore, the neural network method is used in a case study to predict the level of circular economy and the importance of each variable according to the sensitivity by the Lek’s profile method.FindingsIt is based on a descriptive quantitative analysis, where a checklist with 91 items and nine study variables is made, defined from a bibliographic study and business practice. Furthermore, the neural network method is used in a case study to predict the level of circular economy and the importance of each variable based on sensitivity.Research limitations/implicationsThe application of the tool requires prior knowledge of the circular economy approach, which is why specialized personnel are needed for its application. This makes research more expensive in time and human resources.Practical implicationsThe practical and methodological contribution of this work lies in the feasibility of the tool that favors the definition of improvement actions for the implementation contribution to the circular economy in business practices.Social implicationsThe social contribution is framed in the gradual transition to circular economy approaches in underdeveloped countries.Originality/valueThe use of the neural network method to predict the level of circular economy in a case study allows making decisions in a predictive way. This encourages the development of the circular economy according to the context needs.

“…There are several actions that involve the entire school community in favor of the mitigation of waste within educational units. Furthermore, as already emphasized, the transition to EC requires affirmative action by the government, companies and consumers, based on general awareness raising [54].…”

Management Food Waste in Municipality Schools: An Analysis from a Circular Economy Perspective

et al. 2023

Background: Food waste is a situation that triggers certain controversy, considering that there is still a significant number of people who do not have access to healthy and nutritious food every day. The management of food leftovers from school lunches depends on the creation of measurement mechanisms. Thus, current characteristics of schools should be identified in order to mitigate and better manage these leftovers. This study addresses this gap, that is, it seeks to understand how food waste management is carried out in schools from a circular economy perspective. Methods: Focusing on the management of school lunches in municipal schools, this study aims to build an inductive interpretive theory in order to understand how schools promote food waste management. Results: Loss estimates and their monetization were identified and explained, and alternatives for waste recovery using the ReSOLVE framework were proposed. Conclusions: Therefore, it was assumed that the perspective of circularity is a possible and viable way to manage food waste in school lunches. Stakeholder engagement and awareness raising become necessary premises for success in the food circularity journey.

“…De acordo com Ferreira, Rocha e Silva (2013), a sustentabilidade aparece como sendo uma cadeia de ações, devendo ser pensada e executada, elevando os padrões ambientais, econômicos e sociopolíticos da sociedade, caso contrário teremos uma sustentabilidade "pintada de verde". Partindo dessa ideia, a QV vem para auxiliar no processo de sustentabilidade ambiental, contribuindo para resolver problemas graves que afetam a humanidade (Ferreira, Rocha & Silva, 2013), tratando da prevenção dos riscos, metodologias químicas e planejamentos da ação para a criação, desenvolvimento e aplicação de produtos e processos químicos para reduzir ou eliminar o uso e a geração de substâncias tóxicas (Anastas & Warner, 1998;Souza et al 2020).…”

Considerando a importância das atividades que integram a produção de sabão com matéria graxa residual, as relações com o meio ambiente e conceitos científicos de Química e Biologia, apresenta-se um protocolo “verde” para a produção de sabão líquido ecológico, que permite explorar os 12 princípios da Química Verde como forma de possibilitar sua integração no processo de ensino e aprendizagem de Ciências da Natureza. Neste sentido, é indicado a consideração de requisitos importantes para pensar atividades teórico-práticas nessa perspectiva: evidenciar os riscos físicos, ambientais e a saúde dos reagentes e produtos envolvidos na fabricação de sabões e determinar o índice de saponificação da gordura residual para evitar excesso de soda cáustica. Ainda, orienta-se a avaliação da verdura química do procedimento segundo as métricas holísticas e as métricas de massa da Química Verde. Por fim, apresenta-se uma proposta de articulação da Química Verde na Educação Básica, que podem ser desenvolvidos por meio dos três momentos pedagógicos. De modo geral, as ações práticas apresentadas nesse artigo, reforçam a importância do pensamento crítico em torno do tema Química Verde e sustentabilidade articulada ao Ensino das Ciências da Natureza.
