中国汽车行业钢铁物质流代谢研究   总被引:1,自引:0,他引:1  
汽车行业在我国发展迅速,汽车行业的钢铁物质流代谢在整个国民经济的钢铁物质流代谢系统中的影响已不可忽视。研究中国汽车行业钢铁物质流代谢对再生资源利用产业、再制造行业的发展具有重要的意义。结合系统动力学方法及相关经验模型对中国汽车行业钢铁物质流代谢进行研究。首先通过Gompertz模型研究了世界主要国家汽车千人保有量与时间的关系,以此为参照设定中国汽车千人保有量随时间变化的相关参数。其次利用中国汽车行业钢铁物质流循环代谢的系统动力学模型,对系统关键流量、存量的动态变化过程进行考察分析,通过设定不同情景、不同寿命分布,研究中国汽车报废量、钢板和零件耗钢量随时间变化的规律,并探讨了零件再制造、汽车轻型化等问题。选取汽车千人保有量为260辆/千人的中等情景进行分析,考察时间为2011-2050年,结果表明报废汽车年折钢量与汽车行业钢材年消耗量比值不断上升,最终可达到1.2;再制造行业潜力巨大,零件再制造数量将近8亿件;延长汽车4 a寿命,可减少近一半的汽车报废量;通过轻型化,钢材年消耗量可减少18%,减少近650万t,累计减少1亿多吨钢材,节省大量资源,经济和环境效益显著。  相似文献

Understanding the product's ‘end-of-life’ is important to reduce the environmental impact of the products' final disposal. When the initial stages of product development consider end-of-life aspects, which can be established by ecodesign (a proactive approach of environmental management that aims to reduce the total environmental impact of products), it becomes easier to close the loop of materials. The ‘end-of-life’ ecodesign methods generally include more than one ‘end-of-life’ strategy. Since product complexity varies substantially, some components, systems or sub-systems are easier to be recycled, reused or remanufactured than others. Remanufacture is an effective way to maintain products in a closed-loop, reducing both environmental impacts and costs of the manufacturing processes. This paper presents some ecodesign methods focused on the integration of different ‘end-of-life’ strategies, with special attention to remanufacturing, given its increasing importance in the international scenario to reduce the life cycle impacts of products.  相似文献

Solid Freeform Fabrication (SFF) technologies such as Direct Metal Deposition (DMD) have made it possible to eliminate environmentally polluting supply chain activities in the tooling industry and to repair and remanufacture valuable tools and dies. In this article, we investigate three case studies to reveal the extent to which DMD-based manufacturing of molds and dies can currently achieve reduced environmental emissions and energy consumption relative to conventional manufacturing pathways. It is shown that DMD's greatest opportunity to reduce the environmental impact of tool and die manufacturing will come from its ability to enable remanufacturing. Laser-based remanufacturing of tooling is shown to reduce cost and environmental impact simultaneously, especially as the scale of the tool increases.  相似文献

Over the past decade, there has been an increasing interest in product take-back, product recovery and the (re-)distribution of these products. The automotive sector, in particular, has a strong history of product recovery operations, such as remanufacturing. Alongside this development, an academic interest in the management of re-use, recycling or remanufacturing has evolved and developed into the field of closed-loop supply chain management. Closed-loop supply chain management, however, is only characterised by a short research history, the earliest contributions can be found on reverse logistics and were published in the early 1990s. Due to the novelty of the field there are still a large number of unsolved research problems. One of these is the question for the rationale behind product recovery operations. This research is based on in-depth case studies within the remanufacturing facilities of a major European Vehicle Manufacturer. The article examines whether the ‘classic’ motives for product recovery are applicable to automotive remanufacturing. It concludes with a summary of the contributions this research makes to theory, to industry and to future research in the field.  相似文献

Severe industrial pollution has largely hindered the sustainable development of China. Taking Shenzhen’s electroplating industry as a case, this article investigates the current status of the industry and proposes a specialized policy framework to push its environmental innovation. There is a relatively complete environmental management system in Shenzhen’s government, but it does not work well when dealing with the electroplating industry, mainly because it lacks regulation aiming at production technology, which is the underlying decisive factor of the environmental performance of the industry. So, we first develop an evaluation criterion, which incorporates a technological index about whether enterprises engage identified obsolete technologies. With this evaluation criterion, enterprises are classified into “advanced” and “obsolete”. Then, we propose specific policy suggestions for different types of enterprises, including command and control mixed with economic tools, voluntary agreements, establishing electroplating parks, and improving current management system. Finally, we assess the impact of the policy proposal and prove it to be conducive to the sustainable development of the industry and conclude it from a more general perspective.  相似文献

加快环保产业发展是中国既定的促进经济持续健康发展的重要战略性举措之一。本文在梳理中国环保产业现状的基础上,重点从科技促进环保产业发展的角度进行分析,认为尽管科技在环保产业发展中发挥着支撑和引领作用,然而研发技术的单一性、关键设备的欠稳定性以及技术的经济成本过高等因素限制了技术对产业支撑作用的发挥。本研究认为,环保技术的研发应该充分与环保产业发展特点相结合,政府要加大创新型环保企业的培育,加强不同科技资源的统筹和衔接,完善科技扶持政策,加强创新支撑体系建设,鼓励商业模式的创新。  相似文献

Achieving eco-efficient production and consumption systems requires ‘closing the loop’ to create cyclic systems. Product systems based on remanufacturing, where used products or components are restored to ‘as new’ condition for reuse, offer the potential to create such cyclic systems. For some existing manufacturers, the economic efficiency of remanufacturing is clear and it has become a widely held assumption that such systems would also be more eco-efficient. However, this assumption has not been systematically tested. This research attempted to quantify the life cycle environmental benefits achieved by incorporating remanufacturing into a product system, based on a study of Xerox photocopiers in Australia. The study found that remanufacturing can reduce resource consumption and waste generation over the life cycle of a photocopier by up to a factor of 3, with greatest reductions if a product is designed for disassembly and remanufacturing. This research represents a first-level assessment, limited by certain estimates and assumptions. It is intended that this research will form the basis of a larger, more detailed study of Xerox remanufacturing, worldwide.  相似文献

The end-of-life vehicle (ELV) Directive in Europe aims to generate environmental gains through increased levels of vehicle recovery and a reduction in the use of hazardous substances. This paper presents an evaluation framework based on five anticipated changes that could result from the ELV Directive. These changes relate to three areas: (a) vehicle design, (b) level of ELV recovery, and (c) information provision. We evaluate the extent to which expected outcomes have materialized since the establishment of the ELV Directive. Current information provides an emerging picture of the impact of ELV legislation. We show that legislative factors and market forces have led to innovation in recycling, increased hazardous substance removal and improved information dissemination. Such actions may be sufficient to reach ELV Directive targets and could have spill-over benefits to other industries. Carmakers are also taking steps to design for recycling and for disassembly. However, movement toward design for re-use and remanufacturing seems limited. Increasing the level of re-use and remanufacturing will be a key part of moving toward sustainable vehicle production.  相似文献
