The purpose of this paper is to investigate reverse supply chain (RSC) practices and their obstacles using case studies of Moroccan companies. The authors present the main findings of case studies’ analysis along with a discussion of an RSC framework for further directions of research.

A qualitative approach was adopted and semi-structured interviews with Moroccan companies were conducted using an interview guide.

The authors present an RSC model that encompasses remanufacturing, refurbishing and disposal processes. The authors believe that this model would constitute a promising framework for further research. The findings show that the successful implementation of RSC depends on many factors, but the company’s attitude (proactive or conservative) is one of the most critical determinants in RSC initiatives. Furthermore, the results of the case studies indicate two types of inhibitors: external and internal. These findings confirm the results of previous research on environmental sustainability obstacles in general and RSC obstacles in particular.

This study has some limitations that provide future research opportunities. Because this study is qualitative, further statistical support is needed to justify wider generalisation of its findings. Further studies might therefore investigate RSC practices in developing countries other than Morocco to increase the external validity of the results.

The findings can help firms to gain better understanding of their RSC and particularly the link between forward and RSCs. Consequently, companies can upgrade their business models to better control their RSC activities.

The relevant literature about RSC practices has mainly targeted manufacturing sectors in developed countries, and few studies have been conducted on developing countries. Research on RSC practices in developing countries in general and African countries in particular is sparse. This is one of the first articles written to address this gap by investigating RSC practices in Morocco.

This article sheds light onto the increasing problem of product returns, which is exacerbated by growing e-commerce. Many retailers and academics are oblivious to the nature and scale of this challenge. Interdisciplinary research is needed to develop supporting theory, and cross-functional teams are required to implement measures addressing economic, ecological and social sustainability issues.

The initial project adopted a multi-case study approach, whereby returns processes were mapped, vulnerabilities identified and a returns cost calculator was developed.

Product returns processes are usually complicated, prone to internal and external fraud, inefficient and lack sustainability. They can generate considerable losses to the business, especially as returns data are often not systematically collected, monitored or reported to senior management. There are important implications for strategic and operational management, namely the need to develop a concept for Lean returns systems.

Product returns are a unique and understudied but growing field in academic research, with only few publications over the last two decades. Yet the phenomenon is causing increasing problems in business and society. Robust solutions could achieve great financial and non-financial impacts.

This paper aims to discuss how the theory of complex thinking can be considered an interesting element in engineering education, especially in the context in which challenges toward sustainable development are multidisciplinary.

This viewpoint synthesizes the main reflections and discussions generated during a process of debate, research and creation of a proposal for an undergraduate engineering course at a higher education institution in Brazil. The literature on engineering education, sustainability and complexity was considered in an integrated way. Debates were conducted considering the authors’ knowledge and experience as professors of engineering courses and researchers in the field of sustainability. A qualitative and reflexive approach was used to organize the main discussions.

The prevailing classical engineering paradigm trains professionals to think from a Cartesian, reductionist perspective, appropriate for solving well-structured problems with known solution paths and convergent answers. However, addressing sustainability challenges requires a different kind of thinking capable of dealing with situations characterized by uncertainty, emergence and incompleteness of knowledge. Complexity thinking can be useful for this purpose as it provides a broad system approach to deal with ill-defined, ill-structured and unpredictable problems. This study can be understood as a call to researchers and professionals to consider the value and importance of complexity thinking to advance engineering education for sustainability.

The need to overcome the limits of the classical engineering paradigm is emphasized in the context of sustainability. Complex thinking is considered as a path toward a paradigm shift in engineering education for sustainability. It can contribute to the training of professionals to face pressing challenges now and in the future. This viewpoint provides some insights to enhance debates on education engineering.

Phenolic compounds, including flavonoids, are nutritionally important for their antioxidant activities and protective functions against disease risk caused by oxidative stress. These compounds are primarily found in fruits, and mangoes are an important source. This paper aims to address these issues.

In this work, the antioxidant activities of mangoes cultivated in three different ways were evaluated by their ability to capture free radicals using the DPPH radical.

The results showed that the biodynamic mangoes had highest antioxidant activity in mature‐green and ripe fruits, while for those of organic origin the antioxidant activity was highest in unripe fruits. The organic mangoes also showed highest values of phenolic compounds at all maturation stages. The mangoes from conventional crops had lower values for all parameters evaluated in this study than the organically and biodynamically cultivated fruits.

This work brings an important contribution in the field of agriculture at a time when organic and biodynamic systems of cultivation are an alternative to the conventional system and that pollutes the environment and produces food that contains quantities of chemical contaminants that can damage the health of the consumer. The comparison in phenolic compounds content, flavonoids and antioxidant activity in biodynamic, organic and conventional systems is original and of great importance, showing that the ecological cropping systems are less harmful to the environment and promote improvements to the chemical composition of foods.
