“…The transition from a waste management system based on a linear economy to one based on circular economy and how this translates into public policy is a global challenge. In the case of South American countries, MSW management is a great challenge, since its generation is continuously increasing [37]. In addition, there are other problems, such as inadequate waste disposal, financial insufficiency in urban systems and the presence of an informal recycling sector [38][39][40].…”

For the first time in the scientific literature, this research shows an analysis of the implementation of circular economy techniques under sustainable development framework in six municipalities with a depressed economy in Colombia. The analysis is based on solid waste data production at a local scale, the valuation of the waste for subsequent recycling, and the identification and quantification of the variables associated with the treatment and final disposal of waste, in accordance with the Colombian regulatory framework. Waste generation data are obtained considering three different scenarios, in which a comparison between the simulated values and those established in the management plans are compared. Important differences have been identified between the waste management programs of each municipality, specifically regarding the components of waste collection, transportation and disposal, participation of environmental reclaimers, and potential use of materials. These differences are fundamentally associated with the different administrative processes considered for each individual municipality. This research is a good starting point for the development of waste management models based on circular economy techniques, through the subsequent implementation of an office tool in depressed regions such as those studied.

“…This function is only executed at the national level by the SSPD, which cannot to simultaneously cover all providers in each of the municipalities in a free market system. Existing organisations may be economically disadvantaged by the entry of new private companies, being governed under the new national guidelines, which are general and contain an innovative model, combining companies with capital and organisations made up of low-income people, which has not been previously implemented; which leaves to the SSPD, monitoring of acts of unfair competition that can be detected late, time for which WPs' organisations may have disappeared or been severely injured (Márquez & Rutkowski, 2020). In this aspect, the Brazilian national approach is less dangerous, as the law does not require the public bidding for WPs' organisations formed by low-income individuals to provide services in the management of recyclable materials.…”

“…In Colombia, waste recycling was initially motivated because of the crisis of violence which deprived millions of peasants of their lands from 1950 (Abramovay et al, 2013;Coelho et al, 2011;Rosaldo, 2019); while in Brazil, this is motivated by the value chain of recyclable materials and the demand for intensive labour to collect them, mostly performed by WPs (Rutkowski & Rutkowski, 2015). It is worth mentioning that in Colombia, since the 1990s, the waste sector has been governed by the principle of free competition, encouraging a high percentage of organised WPs to be entrepreneurs, becoming the most innovative model of inclusion globally (Márquez & Rutkowski, 2020;Parra, 2016;Sing, 2018). A summary of socioeconomic aspects, waste management information and WPs' characterisation in both countries are presented in Table 1.…”

This article aims to identify and comprehend the challenges and strengths behind public policies on integrating waste pickers (WPs) within waste management systems in Colombia and Brazil. In both, WPs started to come together and found organisations and external agents such as NGOs began to support organised groups of WPs. After 10 years of judicial court actions in Colombia, WPs organisations were finally recognised in legislation, while in Brazil, they were recognised in 2007 in one of the national policies through lobby. Today, there are almost 700 WPs organisations formalised in Colombia and 1700 in Brazil. Their public policies’ main achievements and challenges are exposed to supply knowledge to other countries interested in this theme. A Roadmap for the organisation and formalisation of WPs within waste management systems was created. This constitutes a source of information for policymakers in other emerging economies to address this in their territories.

“…This restorative or regenerative circular approach to resource utilization creates an opportunity to minimize unnecessary waste output through improved resource efficiencies, offered by long-lasting medical devices that allow for reuse, repair, remanufacturing, or high quality recycling. 8 This CE approach strives to slow, narrow and close socioeconomic material cycles, 9 by reducing absolute material flows. 3 , 7 , 10 It is fundamentally different to a traditional linear economy whereby raw materials are collected, transformed into products, used once, and discarded as waste.…”

Purpose Within the hospital, surgery is recognized as a resource-intensive activity that disproportionately generates large volumes of healthcare waste. Single-use, disposable medical supplies contribute substantially to this problem, and more broadly to the depletion of scarce resources. Given that many surgical procedures utilize surgical stapling techniques, this study uses surgical stapling systems as functional units for evaluating the waste prevention potential of switching from single-use systems (SUSs) to multi-use systems (MUSs). Materials and Methods Two frequently used surgical stapling systems, Ethicon’s SUS: ECHELON FLEX™ and Medtronic’s MUS: Signia™ Stapling Technology, were mechanically deconstructed to their individual raw material components to calculate the composition of each system. Total waste as well as extended resource use (the total material requirement [TMR]) were then calculated for three different surgical procedures; laparoscopic sleeve gastrectomy, laparoscopic gastric bypass, and video-assisted thoracoscopic (VATS) lobectomy. The differences in outcomes for SUSs versus MUSs were then calculated. Results For each surgical procedure considered, switching from a SUS to a MUS led to a reduction in total waste accumulated per procedure and TMR. Reductions in waste were 40% (sleeve gastrectomy), 70% (gastric bypass), and 62% (VATS lobectomy). The TMR reductions were higher, at 92% (sleeve gastrectomy), 96% (gastric bypass), and 95% (VATS lobectomy). Both waste and TMR reduction were realized with the MUS system as long as the reusable parts were used more than four times. This was true for all analyzed surgical procedures. Conclusion Switching from a SUS to MUS facilitates a reduction in total surgical waste and TMR for sleeve gastrectomy, gastric bypass, and VATS lobectomy surgical procedures.
