A challenge faced by some companies in the residential building sector is to cope with the complexity introduced to respond to the increasing diversity of customer demands in a profitable and sustainable way. Mass customisation (MC) has been described as a strategy to deliver customised products at costs and delivery times similar to mass production. The implementation of this strategy can be supported by several information and communication technologies emerging in the Industry 4.0 paradigm, which has been named Construction 4.0 in the construction industry. The aim of this research work is to identify the synergistic potential between Construction 4.0 technologies and the implementation of MC practices in the construction sector. A decision matrix associating a set of MC practices and C4.0 technologies has been devised based on a literature review. Specialists assessed the relationships between items, and the Jaccard similarity index was calculated to understand which Construction 4.0 technologies should be jointly implemented to support MC strategies. As a secondary contribution, this study has also proposed a method to guide companies in the identification of technologies that can support the implementation of MC in specific contexts.
Providing the correct destination at the end of the product's use phase is essential for value recovery and to reduce the environmental impact at this lifecycle stage. To understand the e-waste recycling behavior among users, this article aims to identify the most common destinations given to smartphones when they are no longer used. A systematic literature review was carried out, and 13 studies were selected for a meta-analysis. The variable is the selection of the most common destinations for e-waste: reuse and recycling (recovered value), storage and informal collection (missed value), and household waste (destroyed value). The results present a summarized measure with the combined proportion of the studies for each category. Studies were weighted by the precision of confidence interval estimates presented in Forest Plots. The main results point out common problems and demonstrate how the strategies and policies adopted in each country can influence the chosen methods of disposal. These specificities require unique strategies to deal with local problems. As a secondary contribution, this study proposes guidelines to reduce e-waste generation and to create awareness and infrastructure to increase value recovery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
