“…For instance, Yang et al (2018a, b) investigated waste disposal and management to reduce poverty and pollution in low-and middle-income countries. Li et al (2020) studied effective policy tools to recycle the waste of construction and demolition. Liu et al (2020) considered the effect of construction and demolition waste and its recycling when minimizing waste and protecting natural resources.…”

Green supply chain management considers the environmental effects of all activities related to the supply chain, from obtaining raw materials to the final delivery of finished goods. Selecting the right supplier is a critical decision in green supply chain management. We propose a fuzzy green supplier selection model for sustainable supply chains in reverse logistics. We define a novel hierarchical fuzzy best-worst method (HFBWM) to determine the importance weights of the green criteria and sub-criteria selected. The fuzzy extension of Shannon's entropy, a more complex evaluation method, is also used to determine the criteria weights, providing a reference comparison benchmark. Several hybrid models integrating both weighting techniques with fuzzy versions of complex proportional assessment (COPRAS), multi-objective optimization by ratio analysis plus the full multiplicative form (MULTIMOORA), and the technique for order of preference by similarity to ideal solution (TOPSIS) are designed to rank the suppliers based on their ability to recycle in reverse logistics. We aggregate these methods' ranking results through a consensus ranking model and illustrate the capacity of relatively simple methods such as fuzzy COPRAS and fuzzy MOORA to provide robust rankings highly correlated with those delivered by more complex techniques such as fuzzy MULTIMOORA. We also find that the ranking results obtained by these hybrid models are more consistent when HFBWM determines the weights. A case study in the asphalt manufacturing industry is presented to demonstrate the proposed methods' applicability and efficacy.

“…Inadequate management of construction and demolition waste (CDW) is a worldwide environmental problem that has been increasing over the years due to the growth of the construction industry in developed and developing countries. It is widely recognized that the generation of CDW is a consequence of economic and social development, since these wastes are a subproduct of urban lifestyle (Mesjaszlech 2014; Aslam et al 2020;Li et al 2020b), and therefore the adequate disposal of CDW is an important challenge of modern urban management.…”

“…The amount of CDW generated and the correspondent management practices differ from country to country, depending on the existing policies, regulations, and waste disposal infrastructures (Blaisi 2019;Li et al 2020b;Lv et al 2020). For example, Singapore reports a 99% recycling rate regarding CDW, while China only recycles 5% of the estimated 2,36 billion tons of CDW produced in a year (Lv et al 2020); in Europe the amount of CDW produced is over 870 million tons per year (Bonoli and Zanni 2021), with recovery rates around 90% (European Commission 2020); the Environmental Protection Agency of the United States of America reports 600 million tons of CDW produced in 2018, 24% of which have their nal disposal in land lls (U.S. EPA 2020); in Brazil the amount of CDW generated in 2019 is estimated as 44,5 million ton (ABRELP 2020), but the recycling practices for CDW in Brazil are scarce (Contreras et As waste material produced in the process of construction, renovation or demolition of structures, CDW mainly consists of concrete, bricks, asphalt, excavated soil, metals, wood, ceramics, plastics, glass and cardboard (Yeheyis et al 2013;Ossa et al 2016;Cai and Waldmann 2019;Oliveira et al 2019a).…”

Construction and Demolition Waste (CDW) cause environmental impacts in a worldwide scale. The existing international concern regarding the adequate management of CDW is justified by the large amount of this waste produced in a daily basis, together with its potential hazardous effects on ecosystems and human health. In countries with growing economies, like Brazil, it is of the utmost importance to promote sustainability-oriented practices that can co-exist with economic development. In this scope, the present research proposes strategies regarding the management of CDW based on the Circular Economy principles, focusing the case study of the municipality of Manaus, in the centre of the Amazon Forest. The characterization of the reference situation regarding CDW management in Manaus revealed several deficiencies, namely the lack of reuse and recycling opportunities, the unsupervised disposal of CDW in illegal landfills, together with insufficient surveillance procedures and inadequate policies from regional authorities like the Manaus City Hall and the Amazon’s Regional Council of Engineering and Agronomy (CREA-AM). The acknowledgement of these problems led to the identification of improvement opportunities and to the development and operationalization of Circular Economy promotion strategies: valorisation of CDW through the enhancement of reuse and recycling opportunities, operationalized through a mobile phone application; inclusion of sensibilization and surveillance practices regarding professional activities related to CDW management on the CREA-AM inspection plan; and the proposal of alterations in the municipal policies regarding CDW disposal in the public landfill. These strategies have been implemented in the Manaus municipality, but are easily adaptable to other Brazilian municipalities and even to other countries’ realities.

“…Generation, transportation, and treatment of C&D waste are key information to establish a systematic strategy for waste management. Many studies have attempted to investigate generation rates of different materials in C&D waste by site visit, questionnaire, expert interview, and desktop survey, and further predict their values in the future based on computer simulation (AlZaghrini et al, 2019; Islam et al, 2019; Kleemann et al, 2017a; Li et al, 2020; Miatto et al, 2019; Wang et al, 2019; Wu et al, 2016). For instance, the C&D waste generation in a region can be calculated by multiplying the generation rate of C&D waste from site survey and the gross floor area (= surface area × floor) according to local construction planning (Yu et al, 2020).…”

Urbanization and related construction activities generate massive construction and demolition (C&D) waste, which poses considerable risks to the environment and human health. However, it is difficult to assess the significance of these issues without a quantitative understanding of spatial patterns of C&D waste generation (source), transportation (flow), and treatment (sink). This paper maps source, sinks, and flows of C&D waste by coupling a geographic information system and material flow analysis. The methodology is new in the field of C&D waste quantification at the city level, especially downscaling to 5 km × 5 km grids. The results showed that a total of 37.72 million metric tonnes (Mt) of C&D wastes were generated in Beijing, 2019, and ~72% of them were reused and recycled. In space, C&D waste generation in suburban and rural districts (28.73 Mt) was over three times more than that in the downtown area (8.99 Mt). However, the downtown area was the net source region and transported massive amounts of C&D waste to suburban and rural districts. In comparison, several suburban and rural districts had self-sufficient treatment capacity. Our study highlights that a series of C&D waste maps on multiple spatial scales are of great help to design effective policies for waste management by providing spatial details of magnitude and components, and explicitly recognizing primary source and sink areas in cities.
