我国是能源消费大国,"富煤贫油少气"是我国能源资源分布的突出特点。当前,我国煤炭资源利用以直接燃烧和传统煤化工为主,能源转化效率和资源综合利用水平极低,环境污染较大。过度依赖于能源的煤炭产业结构和经济发展方式,导致煤炭产业初级化、重型化、单一化问题突出。因此,实现绿色采矿、发展循环经济、开展煤炭深加工、提高煤炭资源就地转化水平等一系列转变煤炭产业经济的新发展模式,已成为实现我国经济发展方式转变、实现资源型国家可持续发展的最现实有效的选择。 相似文献

结合氯碱化工园区的实际情况,建立了氯碱化工园区循环经济评价指标体系,运用层次分析法(analytical hierarchy process,AHP)确定了指标体系中各指标的权重,运用模糊综合评判(fuzzy com prehensive evaluation,FCE)理论,建立了氯碱化工园区循环经济综合评价模型,并将这一模型应用于某氯碱化工园区循环经济的综合评价。实例表明:模糊综合评价方法可操作性强,可在氯碱化工园区循环经济综合评价中广泛应用。 相似文献

This study contributes to the conceptualization of a sustainable circular business model (CBM), the application of the circular economy (CE) by companies. The study utilized a three-level framework adapted from the CE literature with company (micro), supply chain (meso) and society (macro) levels. This multiple-case study in the textile industry included two types of companies operating in the CE: companies founded on the sustainable principles of a CE (natives) and companies transitioning to a CE from the linear economy (adopters). The findings show that the adopters emphasized long-term economic sustainability on a company level and implemented CE elements to varying degrees on all three levels. The natives pursued business decisions from environmental and social sustainability standpoints, and the three levels were integral in their systemic approach to a CE. The study highlights two key claims: established operational structures and economic volition hindered adopters in their systemic CE implementation, and an integral part of the CBM for natives was a proactive approach towards the society level. 相似文献

Extended producer responsibility (EPR) is a proposed policy approach to promoting the circular economy (CE) within the European Union. This research used a policy Delphi to explore perspectives on improving EPR policies to further contribute to the CE goals of the Netherlands. Both the potential improvement and critical reflections discussed by CE and EPR experts and practitioners from this study contribute to a more detailed understanding of the future governance of CE practices. We present various activities to improve EPR and insights from Delphi participants that emerged from the study. This paper shows that whilst actors agree, in essence, that there is a need for modifying EPR, what the specific changes to the form are and to whom the new responsibilities apply is contested. 相似文献

Circular business models (CBMs) have huge potential to deliver economic, social, and environmental benefits, but CBMs have yet to be implemented widely in industrial settings. One reason is that they are often presented as one-size-fits-all solutions, but this is misplaced because product-specific criteria and company capabilities determine the correct choice and implementation of CBMs. Therefore, the purpose of this paper is to investigate how CBM selection and capability development facilitates the implementation of CBMs. For this purpose, we have adopted a qualitative research approach and undertaken 25 explorative interviews in three large Swedish manufacturing companies. In this paper, a CBM implementation framework consisting of two parts has been developed. The first part addresses the choice of the appropriate CBM based on tactical configurations. The second part provides a capability development path by explicating underlying routines that need to be progressively developed in order to move smoothly to more advanced CBMs. 相似文献
