This paper investigates whether eco-industrial parks (EIPs) offer possibilities to implement sustainable development policies. EIPs are based upon industrial ecology principles that suggest industrial systems can operate in a similar fashion to natural ecological systems. Drawing upon a survey of all identifiable EIPs in the USA and Europe and in-depth interview surveys of 16 EIPs, the research discovered few examples of networking between firms or processes using wastes and materials recycling. Most EIPs are at a very early stage of development, where linkages are potential rather than real. The problems encountered in developing EIPs from scratch suggests that a more fruitful approach is to build upon existing and potential linkages within a locality, assisted by a pro-active policy to encourage interchanges. 相似文献

For the past several years, cleaner production, or what is now commonly referred to as eco-efficiency by the business sector, has been promoted widely, but in a relatively ad-hoc manner. As a consequence, the advantages to industry and society stemming from the uptake of eco-efficiency have been difficult to quantify and assess. This paper details how the Queensland Food Processing Eco-Efficiency Project has attempted to overcome some of these barriers by implementing a two year project focused on: involving and gaining the support of as much of the industry sector as possible; using external expertise, providing the support and technical advice essential to the successful uptake of eco-efficiency by businesses; establishing the key environmental concerns for the industry; identifying realistic eco-efficiency opportunities through site assessments and visits; developing case studies based on quantifiable outcomes; developing tools and resources to enable businesses to successfully implement their own eco-efficiency initiatives; the wide and free distribution of these resources and tools to the entire Queensland industry; follow up workshops and awareness briefings together with the eventual development of a forum to allow effective industry networking to continue. 相似文献

Eco-industrial system is a typical complex adaptive system that generates intricate patterns with given constraints. In this paper, a universal variational principle on eco-industrial system is highlighted as: an eco-industrial system always tries to find an optimal process to obtain maximized flux under given constraints. Basing on this principle, the dynamic mechanisms on the formation and evolution of eco-industrial structure are then revealed. The fractal growth of eco-industrial pattern is discovered. By mapping theoretical model to artificial neural network of Self-Organization Feature Map (SOM), some eco-industrial patterns are then simulated and studied as typical examples basing on historical data of past years. The simulation results are in good agreement with the theoretical analyses. Here we not only make a renewed effort to deepen the theoretical understanding of the evolution of eco-industrial pattern, but also try to provide new implications on design, improvement and prediction of the structural evolution of the eco-industrial parks. 相似文献

生态工业园区建设是工业领域加快经济方式转变,推进工业生态文明建设的重要组成部分.园区层面基础设施共享对推进园区生态化建设、构建产业共生具有重要的支撑作用.能源基础设施越来越多地在园区生态化发展中发挥着重要作用.以杭州湾上虞经济技术开发区为例,研究其2005年以来能源基础设施多功能化发展对推进园区生态化发展的作用.通过拓展能源基础设施的功能,引导热电企业成为解决环境问题的要素,在污泥干化焚烧、有机废气焚烧等方面充分发挥作用;同时逐步增加清洁能源和可再生能源的利用比例,减少一次能源中煤炭的消费量.形成了能源基础设施多功能化推进园区生态化发展的示范模式.上虞经济技术开发区能源基础设施多功能化显著地推进了生态化发展,在区域循环经济发展中承担着分解者的重要作用,其实践模式将为国内众多类似化工园区的绿色低碳循环发展提供积极的借鉴和参考作用. 相似文献

This article examines the opportunities for fostering sustainable development through public sector sourcing from small- and medium-sized enterprises (SMEs). Buying from small businesses can make such contributions in a variety of forms, ranging from a contribution to local economic development through providing innovative green products and services, particularly in the food sector, to helping the public sector organisation to better align its operations with its community. Sourcing from small businesses also has implications for the governance of sourcing processes and can benefit from a partnership approach. Barriers to public sector sourcing from small businesses are discussed and suggestions made on how these can be overcome. 相似文献

基于LEAP模型的厦门交通能耗及大气污染物排放分析 总被引:3,自引:0,他引:3
交通部门能源消耗和污染物排放的比例较大,增长迅速,因此研究交通部门的节能减排措施显得尤为迫切。文章以厦门市城市交通部门为例,基于LEAP模型构建Xiamen-2008Tra交通模型,研究从基准年2008年到2030年的能源消费量以及CO2、SO2、NOx和PM10的排放量,评估各种节能减排措施的效果。模型设定了基准情景和最佳情景,前者作为参考情景假设政府没有采取任何措施来抑制交通部门能源增长,后者作为最乐观情景包括私家车控制、燃料经济性调整、新能源车推广、燃料税和生物燃料推广五个节能减排子情景。研究结果表明:2030年最佳情景要比基准情景节能36.08%,CO2、SO2、NOx和PM10的排放量分别减少40.46%、47.06%、32.07%和44.91%;在各种节能减排措施中,私家车控制措施节能减排效果最好。 相似文献

The role of business in sustainable consumption 总被引:2,自引:0,他引:2
This paper explores the role of the business community in promoting sustainable consumption. While businesses play an important role in shaping social trends, including the growth of material consumption, allegations that individual corporations wield excessive power may have been overstated. Most of the time corporations are simply playing by the rules and culture of the market.Businesses have mostly assumed that their contribution to sustainability lies in improving eco-efficiency—staying within the current business framework. But sustainable consumption will require wider change, including shifts in the incentives that shape the actions of businesses and others, and a change in the culture that underlies market expectations. Firms, governments, the media and civil society may need to enter a dialogue together to develop a new story about the nature of prosperity and the role of the business community in promoting it. The initiative is most likely to come from civil society. 相似文献

The concept of industrial ecology has been applied in this research to study possibilities to develop an eco-industrial cluster model for fishery production industry in Vietnam. By learning from experiments of other developed countries, we apply the principles of Industrial Ecology and of Ecological Modernization in the context of Vietnam. We design a physical-technological conceptual model for minimizing waste in agro-industries, with a case study of frozen shrimp production. The results indicate that it is possible and feasible to develop an eco-industrial cluster including aquaculture, fishery processing companies, by-product plants, and wastewater treatment units. By doing so, aquaculture and industry can cooperate for environmentally sound development. Actors and institutions that may govern the proposed eco-industrial cluster of shrimp processing industry are also analysed in this paper. The economic feasibility of the designed eco-agro industrial cluster for fish production in Vietnam depends on the energy savings and effective revenues gained from selling the produced valuable materials, such as Chitosan and animal feed. 相似文献

The world's natural gas consumption continues to grow, increasing its market share of total primary energy consumption. Among the major fuels, natural gas is expected to provide the greatest increase in energy consumption in the world energy sector, due to its relatively low environmental impact and high thermodynamic quality. Natural gas plays a significant role in the energy sector because of its environmental qualities and energy. We analyzed the natural gas life cycle by using the life cycle assessment (LCA) to compare, from an environmental point of view, four sites of heat production by natural gas combustion. We determined the best site from an environmental point of view for a consumer and which stage (extraction, treatment, transportation, storage, combustion) of the natural gas life cycle pollutes the most. This study confirmed the utility of the LCA in the evaluation of the environmental impact in the energy sector. 相似文献

建设活动消耗了大量能源,研究建筑业能耗测算方法并分析其影响因素有助于建筑业的节能减排. 采用投入产出生命周期评价模型测算建筑业能耗,分析建筑业能耗对部门间联系、部门能源强度和建筑业规模等因素变化的敏感性,提出部门对建筑业能耗的技术责任系数和结构责任系数,以判断部门在降低建筑业能耗中的责任. 结果表明,2010年我国建筑业能耗为1.07×109 t(以标准煤计);技术责任系数最大的部门是黑色金属冶炼及延压(0.489 8),其次是非金属矿物制品(0.479 8)和化工(0.211 8)等;除建筑业外,结构责任系数较大的部门包括非金属矿物制品(0.276 4)和黑色金属冶炼及延压(0.246 0)等;建筑业能耗对黑色金属冶炼及延压(0.243 8)和非金属矿物制品(0.203 4)等部门能源强度的变化最敏感. 降低建筑业能耗应注重促进高能耗建材生产节能、强化建设活动科学管理、推广高性能低能耗材料应用、提高基础设施建设水平和深化住房市场化改革等方面. 相似文献
