Eco-benefits assessment on urban industrial symbiosis based on material flows analysis and emergy evaluation approach: A case of Liuzhou city, China

Abstract

Chinese government promotes ecological civilization in the-13 th five year planning‖ (2016-2020) period. As a result, ecological impacts become highlight in the national circular economy practices. To apply the eco-industrial development strategy to address the intertwined industrial and regional economic development, as well as related environmental and ecological challenges is key point. Urban industrial symbiosis provides a novel approach to realize the above expectation. Traditional evaluation on circular economy provided critical environmental insights, while to date, trade-offs of circular economy practices, and critical insights on regional eco-industrial development. It will shed a light on ecological civilization construction in China in the new national planning period.

The Potential of Industrial Symbiosis: Case Analysis and Main Drivers and Barriers to Its Implementation

“…While some of the studies carried out only a qualitative analysis, a significant proportion assessed at least one of these benefits. Of the three dimensions of sustainability, the environmental aspect was the most frequently discussed, and the most commonly applied method was the use of environmental indicators [10,13,39,88,105]. The reduction of carbon dioxide emissions was the most frequently addressed in the various analyses [35,36,38,63,70,73,98], followed by quantification of savings in the consumption of resources such as energy, water, raw materials and fossil fuels [9,39,63,88,95], and quantification of the reduction of waste sent to landfills [9,34,39] resulting from the potential application of industrial symbiosis.…”

“…Job creation [45,80,120,121] was the indicator most commonly used to assess the social benefits of realising potential industrial symbiosis relationships. The material flow analysis method [9,10,39,88,111] has also been used several times to quantitatively assess potential industrial symbiosis. The environmental and economic components of sustainability have also been used to optimise and select the best potential symbiosis relationships.…”

A literature review and categorisation of sustainability-aimed urban metabolism indicators: a context, indicator, mechanism, outcome analysis

“…From the CIMO literature review, there are two basic accounting and assessment mechanisms for urban metabolism indicators based on MFA and energy (emergy synthesis) analysis. Most recent urban metabolism mechanisms expand on or supplement these two mechanisms, such as the integrated MFA, the multi-layered urban metabolism indicator framework, the abbreviated urban metabolism, and the energy flow-metabolism ratio analysis (Sun et al 2017, Kennedy et al 2014, Kennedy-Hoornweg 2012, Chen-Wang 2014, Browne et al 2012. The MFA begins with material classification and concludes with a balance sheet that accounts for the categorised materials (Zhang et al 2015).…”

A Holistic Sustainability Framework for Waste Management in European Cities: Concept Development

“…By this it provides information that is relevant to find spatial nearby possibilities for symbiotic use of resources and waste, which can go beyond traditional industrial symbiosis, but could include public and non-commercial actors. Moreover, it implies the development of new social interactions and technological innovations that offers different ways to meet society's demand for products and services [51].…”
