Reverse logistics is “the sequence of activities required to collect the used product from the customers for the purpose of either reuse or repair or re-manufacture or recycle or dispose of it (Fig.1; Agrawal et al., 2015)”. Hence, reverse logistics is, in essence, a circular strategy (since it integrates R-strategies) and it is recently considered as a key step towards…
Last November took place in Glasgow the 26th UN Climate Change Conference of Parties, known as COP 26. This conference was the first one after the 2015 Paris Agreement where parties had to submit their enhanced Nationally Determined Contributions (NDCs) to rise up the ambition to mitigate climate change. NDCs are those national ambitions or goals to limit greenhouse gases…
The concept of Circular Economy (CE) is relatively new, being in 1990 the first time it was defined and described as such by Pearce and Turner (1990). However, the concept remained dormant for about 20 years (Elkins, 2019). It was not until the creation of the Ellen MacArthur Foundation (FEM) in 2010 and its publication “Towards the Circular Economy” in…
The transition to a circular economy aims at closing material loops in order to reduce waste, use resources more efficiently and minimize the environmental impacts. But what are the strategies that the companies can establish to achieve this? In this respect, Potting et al. (2017) apply a useful framework (Fig.1) that defines 9 R-strategies, group them in three main circularity…
Reuse and recycling are the two key strategies to move towards circularity, as reported last month. But several issues arise when assessing the environmental impacts or benefits of applying these strategies. How do these burdens or benefits can be shared between the product being recycled and the next product that will use the recycled material for its manufacturing? What is…
Plastic is a synthetic material, made from organic polymers, that has become essential in current supply chains due to its beneficial properties – light weight, durable and easily shaped – and low cost. Since the 1960s, plastic production has increased by 20 times, with a global manufacture of 360 million tonnes in 2018, 40% of which were used for packaging…
Fresh fruit and vegetables (F&V) is a key sector in the Spanish agriculture. With an annual production of around 20 million tons, it has an economic value of 14 million Euros, contributing to 47% of the value of the Spanish plant production and 29% of the whole agricultural production (MAPA). However, inefficiencies within the F&V supply chains appear in the…
The environmental impact study based on the Life Cycle Analysis carried out by the UNESCO Chair of ESCI-UPF and published in the scientific journal Resources, Conservation and Recycling revealed the advantages of this system. The life cycle analysis of the boxes will allow further improvement of their environmental performance.
