“…Figure 3 shows the processes considered (i.e., the system boundaries) when conducting the cost analysis of the EoL RO recycling into r-UF MBR membranes. The costs of EoL-RO collection and the transformation into UF were adopted from Senán-Salinas et al [7]. The module disassembling was analyzed in Lawler et al [25].…”

“…To illustrate the state of the art of commercial membranes and identify the technological position of the studied r-UF membranes, Figure 4 summarizes the values of the clean water permeability versus the nominal pore size of the commercial membranes and the recycled ones. The costs of EoL-RO collection and the transformation into UF were adopted from Senán-Salinas et al [7]. The module disassembling was analyzed in Lawler et al [25].…”

“…Senán-Salinas et al reported that it would be possible to obtain recycled modules with a price range of 45-100 EUR per module, depending on the recycling strategy [7]. Even though the unitary cost for a commercial UF membrane module could be affected by the peculiarities of every acquisition's transaction, it could be considered that the pristine commercial module prices are between 400-800 EUR per module [7,8]. Therefore, in view of the above data, the use of recycled membranes could offer a competitive alternative to reduce the membrane replacement cost in the MBR process.…”

The use of recycled ultrafiltration (r-UF) membranes, originating from end-of-life reverse osmosis membranes, as submerged flat-sheet membranes in an aerobic membrane bioreactor (aMBR) system is described herein for the first time. A feasibility study of this new approach was performed in a laboratory-scale aMBR system. The r-UF membrane performance was evaluated in terms of permeability, fouling behavior, and permeate quality using a widely used commercial flat sheet microfiltration membrane (c-MF) as a reference. Tests were conducted under steady-flux operation (at 12 and 14 L·m−2·h−1) and a variable trans-membrane pressure. Synthetic wastewater simulating urban wastewater characteristics with approx. 0.4–0.5 g/L COD concentration was used as the feed. The obtained results showed that the rejection performance of the r-UF membrane was similar to the performance of the commercial flat sheet microfiltration membrane (c-MF) under comparable operating conditions. Moreover, concerning fouling behavior, the r-UF membrane exhibited higher fouling resistance compared with the c-MF membrane, although the permeability decline rate was lower. Both membranes had comparable fouling mechanisms behavior, with cake layer fouling resistance accounting for approx. 60% of the total fouling resistance. Finally, a preliminary economic assessment pointed out the potential competitiveness of using r-UF membranes for aMBRs (5.9–10.9 EUR·m−2) and the scaling-up challenges toward industrial applications.

“…The production of recycled membranes using free chlorine solutions is emerging as an alternative management to end-of-life (EoL) reverse osmosis (RO) membrane disposal [28,29]. Senán-Salinas et al recently estimated that around 72% of EoL RO membranes could be recycled in that way [30]. UF-like and NF-like recycled membranes from EoL RO membranes used in desalination plants have demonstrated to be comparable to their commercially available homologues for cross-flow pressure-driven processes [31,32].…”

“…Amongst recycled membrane applications, only two cases assessed their potential use as HWTS system (submerged GDM system configuration) [28,33]. Indeed, the production cost of the second-hand membranes has been estimated to be between 1 USD m -2 [34] and 6 USD m -2 [30]), which could drop the cost of HWTS systems significantly. Since the NF-like and UF-like recycled membranes originate from standard RO spiral-wound membranes, the conventional pressure vessels used in desalination facilities, normally manufactured to host 6-8 membrane modules, remain the most used type of membrane housing available.…”

Strategies and practices to reduce the ecological impact of product returns: An environmental sustainability framework for multichannel retail

et al. 2023

View full text Add to dashboard Cite

Product returns in retail are inherently wasteful and have considerable negative environmental impacts. Besides the monetary costs, they lead to increased transportation, packaging and processing, and the returned items are often discarded. We present strategies and practices retailers can adopt to manage their product returns in a way that reduces environmental impacts. With eCommerce flourishing, product returns have increased significantly. Whilst highest for online sales, they are a challenge across all channels. The importance of developing sustainability management in operations and supply chains is evident from the growing body of literature, but there is a gap regarding the management of product returns in a more environmentally sustainable manner. To address this gap, we interviewed multichannel retailers, retail experts and return service providers operating in the UK and North America. The findings reveal that although retailers have started paying attention to the financial impact of returns, there is little awareness of the scale of environmental impacts. In addition, retailers lack a comprehensive approach to addressing the environmental impact of product returns. Based on our findings, we (1) unpack the barriers inhibiting retailers from developing environmental sustainability plans in returns management,(2) present a set of strategies for retailers to reduce the environmental impact of returns and (3) develop a framework for environmental sustainability in returns management. Our findings and proposed framework have implications for research and practice on addressing the environmental impact of product returns.
