“…This can be related to recycling processes of materials in a technological or biological cycle, such as using biological waste to generate new products. Product variety and composition are becoming more complex, and it has been argued that due to this, the technological challenges for recovery of materials are also increasing (Singh et al, 2014). An important activity for this business model is the organization of take-back systems.…”

“…An important activity for this business model is the organization of take-back systems. Uncertainty of the quality of waste can be a challenge for recycling processes (Singh et al, 2014;Singh and Ordoñez, 2016). When waste is transferred between companies, mismatches can occur in waste supply and demand; if companies do not exchange information on availability and quality of waste, such a match might be hampered (Fraccascia and Yazan, 2018).…”

a b s t r a c tEven though much attention has been given to barriers related to implementing circular business models, so far, no studies have focused on how the barriers differ between business models. Ignoring the possibility of such differences could lead to unjustified generalizations about the barriers to implementing circular business models (CBMs). We identified barriers to implementation and compared them for different CBMs by analyzing 43 case studies of CBMs, based on in-depth interviews with 31 Dutch firms. Barriers were analyzed for the following CBMs: circular supplies, resource recovery, product life extension, and the product-as-a-service model. The barriers identified were classified into two broad categories: internal problems related to the firm itself and external barriers related to the firm's environment. This study shows that key challenges were related to the firm's external environment, and that the barriers differed between the four business models studied. Whereas most internal barriers encountered by the product-as-a-service model were to do with organization (for instance, of lease models), the other models reported these barriers less frequently. External supply chain issues were challenging in the resource recovery, product life extension, and circular supplies models, mainly because of great dependence on third parties for the input of discarded products and waste materials. We investigated the strategies firms used to overcome these barriers. From our findings we conclude that to stimulate the development of circular businesses, firms and policy makers should focus on bespoke solutions and strategies for different types of CBMs.

“…Initially waste management was limited to removing waste before it becomes a health hazard or what is popularly called the public health perspective in policy circles (Wilson et al, 2012;Singh et al, 2014). In the 1960s and 1970s, waste disposal issues became politicized due to the association with the negative impacts on the environment (Singh et al, 2014). This led to a search for sustainable solid waste management systems and the emergence of the "Waste Hierarchy", an integrated approach which seeks to reduce the amount of waste that goes for final disposal (Wilson, Velis, & Cheeseman, 2006).…”

“…As major development drivers, cities have been singled out as contributors to climate change largely through increasing GHG emissions ( UN Habitat, 2013;Ziska, Gebhard, Frenz, Faulkner, Singer & Strake, 2003). Cities are implicated through activities such as land transformation, unsuitable agricultural and industrial practices, and MSWM (Kropp & Reckien, 2009;Singh, Laurenti, Sinha, & Frostell, 2014). Hence, the UN Habitat's Cities and Climate Change Initiative argues that cities must be at the center of efforts to address climate change both in mitigation in its causes and adaptation to its effects ( UN Habitat, 2013).…”

Cities, municipal solid waste management, and climate change: Perspectives from the South

Climate change is arguably the most debated and contentious environmental issue today. Hitherto neglected, the role of cities is beginning to attract attention particularly within the academic milieu. Cities are acknowledged as development drivers but also considered major drivers of climate change as a result of activities associated with the release of harmful substances such as carbon dioxide and greenhouse gases. Municipal Solid Waste Management (MSWM) is noted as a major contributor to climate change due to the release of harmful substances during waste treatment and disposal activities. MSWM remains a challenge across the globe but particularly in the South where many cities lack regular waste collection and disposal services. The paper addresses the gap between the North and South through a critical analysis of the current global debate on cities, MSWM, and climate change. The paper reports that there are major differences between the North and South in almost all components of MSWM, from waste generation to treatment and disposal. A notable difference is that the shift in priority from local burdens to the global concern for climate has occurred mainly in the North. Furthermore, the priorities and needs of cities in the South are largely neglected in the global debate. A major example is the failure to acknowledge the role of the Informal Waste Sector even though it is a prominent feature of MSWM systems and a notable contributor to resource recovery in cities in the South. Lessons from the South suggest that climate change cannot be treated in isolation. Recognition of the role of the Informal Waste Sector is crucial because it introduces other important issues such as urban poverty, local economic development, urban governance and exclusionary practices, and citizenship rights. The paper suggests the need for a more inclusive approach if we are to have a truly global solution to climate change.

Aluminum production industry tailings are considered as hazardous solid wastes accompanied by a variety of serious disposal, environmental, and public health issues. This study is devoted to presenting a promising solution for dealing with such problems. Within the scope of the present study, synthesis of nanostructured γ-alumina from aluminum foundry tailing using a novel process was presented. The proposed process will provide a multilateral advantage to both environment and industries. Firstly, the amount of tailing and accordingly, disposal cost could be partly lessened; secondly, the environmental pollution can be reduced, and finally, if possible, green production of advanced materials from this kind of waste at a rational expense can bring about the conservation of natural sources and also gain economic benefits. Characterization of the as-synthesized products was performed using X-ray diffractometry (XRD), X-ray fluorescence (XRF), Fourier-transform infrared (FTIR) spectroscopy, field-emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDAX), and dynamic light scattering (DLS) for crystalline phase analysis, chemical composition, chemical bond recognition, morphology, elemental analysis, and particle size distribution, respectively. The chemical composition analyzed by XRF indicated that the as-synthesized alumina exhibits a purity of more than 97 wt%. The XRD pattern majorly possessed characteristic peaks related to the gamma phase of alumina. Microstructural analyses by FESEM and TEM confirmed the nano-sized morphology of the as-synthesized γ-alumina.
