水泥工业作为工业生态系统的汇,能够多样化地利用其他行业的副产物,这种典型的产业共生模式可以通过减少资源和能源的消耗带来显著的CO2减排效果.由于产业共生在水泥行业具有一定的普遍性及巨大的CO2减排潜力,所以对水泥工业产业共生现状的了解与分析就显得尤为重要;而通过对产业共生现状的全面了解,才能对现有水泥行业产业共生的程度进行分析,并以此为参照,对未来不同政策与情景下的CO2减排潜力进行量化与评估.为实现对产业共生实际情况的模拟,以水泥-电力行业的产业共生为例,采用最优化的方法,提出了一套基于一般统计数据来模拟产业共生实际情况的系统方法,将技术、经济与政策3类不同的决策变量影响纳入模型,以模拟出最接近真实情景的产业共生情况.为验证模型的有效性,对新乡市水泥-电力行业实际的产业共生情况进行分析.结果表明:新乡市水泥-电力行业间存在普遍的产业共生现象,实地调查中有77.8%(21家)的水泥制造企业利用粉煤灰作为水泥制造的原材料.将一般统计数据与实地调查数据对比发现,一般统计数据能较好地反映企业实际物质投入产出情况;利用一般统计数据,模型对新乡市产业共生网络结构模拟的准确率高达92.6%,显示该模型能较为有效地对产业共生的实际情况进行模拟.   相似文献

Industrial symbiosis (IS) studies the physical flows of materials and energy in local industrial systems using a systems approach. In this study the total fuel and energy use, and greenhouse gas emissions are calculated for an ‘industrial park’ operating in the same manner as an IS. Moreover the relevance of industrial symbiosis, particularly one centred on pulp and paper manufacturing, in moving towards more sustainable fuel consumption and reduced greenhouse gas emissions is discussed. The system is compared to hypothetical stand-alone production. Moreover, possibilities to reduce the energy use and total greenhouse gas emissions of the park are identified.  相似文献

工业共生是循环经济思想实践的重要途径之一,近年来针对国民经济各行业共生模式的理论探讨也越来越多;然而,从实践角度,对各种共生模式在现实中的应用潜力及其现状问题的分析还没有深入展开。文章以燃煤电厂为例,通过现有统计数据分析和政策分析方法,对火电行业及其脱硫产品、热电联产2类共生模式的发展潜力进行了分析。结果发现,全国火电脱硫机组的比例约为80%,然而仅有约50%左右的二氧化硫被去除,其中占脱硫产品90%的脱硫石膏的利用率仅为30%左右,各个环节均有很大的发展空间;此外,热机组仅占全国火电机组装机总容量的18.2%,由于其利用形式多样,发展空间很大;通过梳理2类共生模式相关的政策体系,初步分析了目前可能影响工业共生发展的各种问题。  相似文献

农业生态经济系统耦合是一个复杂的过程,是潜变量与潜变量、潜变量与可测变量及可测变量之间相互作用的结果,结构方程模型的建立很好地描述了这一复杂关系。通过对吴起县、安塞县和宝塔区共建的中尺度生态农业建设试验示范区、米脂县等3个典型区域所代表的黄土丘陵区及其各个区域农业生态经济系统结构方程模型的建立与运算,结果表明:在"退耕还林还草工程"等外力作用下,农业生态经济系统运行模式基本揭示了农业产业与农业资源相互耦合这一本质规律,但现状耦合模式并未充分利用农业资源,系统耦合效果较低。农业产业与农业资源对系统耦合的影响系数分别为0.54和0.16,农业产业和农业资源之间的相关系数只有0.28,即农业资源没有很好地支撑产业的发展,导致农业生态经济系统耦合效果不明显,存在着局部相悖的态势,潜伏了林草资源与其相关产业链网缺失现象。为此,需要强化农业产业与农业资源的互动过程,特别要发展林草及其相关产业,促进林草资源的有效利用,促使系统耦合效果的不断提高,增加经济效益。  相似文献

Industrial symbioses (ISs) and eco-industrial parks (EIPs) are key concepts of industrial ecology (IE). The aim of ISs and EIPs is to minimise inefficient material and energy use by utilising local by-product and energy flows. Industrial symbioses tend to develop through spontaneous action of economic actors, for gaining of economic benefit, but these systems can be designed and promoted via policy instruments as well. A literature review showed that national programmes for eco-industrial parks can be found in different parts of the world. In the action programmes and other sustainable consumption and production (SCP) policy documents of the EU, on the other hand, industrial symbioses gain less recognition as a path to enhanced sustainable production. In this article, we consider this and also analyse how the evolution and environmental performance of an industrial symbiosis system centred on a Finnish pulp and paper mill have been affected by SCP policy instruments. With regard to the system forming the subject of the case study, and Finnish industrial systems in general, policy instruments have succeeded in reducing emissions but not in systematically encouraging operators toward symbiosis-like activities. All in all, few studies exist on the overall impact of policy instruments promoting design of eco-industrial parks. It is not self-evident that symbiosis-like production systems would be sustainable in every case, as the background assumptions for political promotion of EIPs suggest. We concluded that industrial symbioses should be analysed and developed on a life cycle basis, with documentation of the real environmental benefits due to efficient resource use and decreased emissions in comparison to standalone production. ISs can then bring eco-competitiveness to companies in relation to SCP tools, such as environmental permits, ecolabels, and future product regulation based on the Ecodesign Directive in Europe. Indirect encouragement of symbiosis through land-use regulation and planning, in such a way that material fluxes between companies are possible both in operations and in financial terms, may prove effective. The same holds for waste policies that encourage increased reuse of a company’s waste by other enterprises.  相似文献

Despite the fact that all successful, documented cases of industrial symbiosis to this day have been self-organizing, some authors and development officials have suggested that increased public planning might deliver better results in this respect than spontaneously evolved market coordination. This paper takes an historical approach to suggest that comprehensive planning is unlikely to live up to the expectations of its proponents.The essay is structured as follows. The first section provides short case studies of industrial symbiosis in highly different economic and institutional settings, the essentially free-market regime of Victorian England and communist Hungary (1948–1989). The available evidence suggests that market coordination proved much more favorable to the emergence of industrial symbiosis, despite the elaboration of a comprehensive policy to that effect in Hungary. Insights derived from the so-called “Austrian” critique of central planning are then used to explain this paradox. The analysis presented suggests that the Hungarian planners’ failure was not so much the result of the bad implementation of sound policies, but the logical outcome of a top-down approach’s shortcomings. Policy implications for the public planning of industrial symbiosis in a mixed economy are then derived and the case for self-organization is found more compelling. The creation of more innovative institutions that will force firms to “internalize their externalities” while leaving them the necessary freedom to innovate is viewed as an urgently needed and promising path towards increased, sustainable reuse of industrial by-products.  相似文献

Industrial water conservation is an important adaptation to the effects of climate change. In addition to water conservation within individual plants, wastewater can be reused/recycled among different companies through inter-plant water integration (IPWI) schemes. Such schemes are based on the concept of industrial ecology and industrial symbiosis, and can be used to achieve greater water savings than when water conservation is implemented in individual companies separately. However, in IPWI, each participating company seeks to maximise its own benefits. In the absence of centralised authority dictating the terms of water integration schemes, conventional modelling techniques are not appropriate. This paper shows how a game theory-based approach can be used to analyse the interaction of participating companies in an eco-industrial park seeking to develop an IPWI scheme.  相似文献

There is increasing evidence that throughout the world, firms, governmental agencies and NGOs are seeking to stimulate industrial symbiosis. This concept and its application have also been the topic of extensive research. Up till now, this work lacks a more comprehensive theoretical framework, and this paper fills this gap. We provide a theoretical basis for understanding the dynamics through which regional industrial systems change their connectiveness in an attempt to reduce their ecological impact. We position our framework within the field of industrial symbiosis based on a comprehensive literature search in the ISI Web of Science database for publications that listed ‘industrial symbiosis’, ‘eco-industrial park’, or a combination of ‘industrial-ecology’ and ‘regional’ as a topic.The framework conceptualizes industrial symbiosis as a process at two levels: (1) the level of the regional industrial system (RIS), and (2) the societal level where the concept and routines of industrial symbiosis diffuse. We link the dynamics at these levels to changes in ecological impact and increase in institutional capacity. We conclude with a research agenda based on the variables and their basic relationships specified in our framework. The main line of research we propose is to systematically investigate how institutional capacity evolves over time in regional industrial systems and how it affects the ecological impact of such systems. We also propose to investigate how insights from existing literature about stimulating and impeding factors to industrial symbiosis can be understood in terms of mechanisms of transmission and how these mechanisms interact to create nationally distinct patterns of diffusion of industrial symbiosis.  相似文献

Using chemical process simulation to design industrial ecosystems   总被引:2,自引:0,他引:2  
Chemical process simulation (CPS) software has been widely used by chemical (process) engineers to design, test, optimise, and integrate process plants. It is expected that industrial ecologists to bring these same problem-solving benefits to the design and operation of industrial ecosystems can use CPS. This paper provides industrial ecology researchers and practitioners with an introduction to CPS and an overview of chemical engineering design principles. The paper highlights recent research showing that CPS can be used to model industrial ecosystems, and discusses the benefits of using CPS to address some of the technical challenges facing companies participating in an industrial ecosystem. CPS can be used to (i) quantitatively evaluate and compare the potential environmental and financial benefits of material and energy linkages; (ii) solve general design, retrofit, or operational problems; (iii) help to identify complex and often counter-intuitive solutions; and (iv) evaluate what-if scenarios. CPS should be a useful addition to the industrial ecology toolbox.  相似文献

Recovering energy from wastes is a useful strategy for integrated waste and energy management in an eco-industrial park (EIP) and gives promising reduction of wastes, total energy consumption and operation cost. In Jinqiao EIP, Pudong New Area, Shanghai, an industrial symbiosis, based on the energy recovery from municipal sewage sludge and re-refined oil, was proposed in the central heat-supplying company of Jinqiao EIP. It is expected that hot off-gas or part of the steam from the central heat-supplying company could be used for sludge drying and used oil re-refining while the dried sludge and refined oil can be partial substitution for fossil fuel. For the purpose of assessing the environmental performance of this industrial symbiosis, life cycle assessment (LCA) was used and different scenarios were set up in this study to evaluate the Global warming Potential (GWP), Acidification Potential (AP), Eutrophication Potential (EP), Human toxicity air (HTA) and Total Environmental Impact Potential (TEIP) of the system. Results indicate that when the substitute ratio of coal by sludge is 14%, the proposed industrial symbiosis has the least environmental impact. Compared with the current situation (sludge is landfilled), co-combustion of dried sludge and re-refined oil with coal at optimal scale will release less CO2, CH4, NOx, N2O and CO, but more SO2, H2S, NH3, HCl, polycyclic aromatic hydrocarbons (PAHs), non-methane volatile organic compounds (NMVOC) and heavy metals.  相似文献

Complex utilization, a production model analogous to those described by industrial symbiosis, was planned at the Russian Kola Science Center in mid-1980. The model integrates the waste streams of mining industries in the Kola Peninsula in such a way that waste from one industrial operator becomes raw material for another. Using a counterfactual method, this article determines the eco-efficiency of the model between the years 1985 and 2005. A parallel study of the eco-efficiency of the actual system, i.e. in the absence of complex utilization, is then performed for the same time period. The study shows that complex utilization would indeed have yielded increased eco-efficiency, even though not all environmentally harmful emissions would have decreased. As a result of market collapse and the use of upstream pollution prevention together with traditional end-of-pipe technologies, however, the actual system shows net emission reductions similar to those modeled in complex utilization. It is suggested that in systems like the mining industry of the Kola Peninsula, with high production volumes and poorly developed environmental technologies, upstream pollution prevention together with traditional end-of-pipe technologies may prove more attractive than industrial symbiosis, despite the substantial increases in eco-efficiency of the latter.  相似文献

Industrial symbiosis encourages the establishment of a broad eco-industrial network so that more synergy opportunities can be identified. By linking municipal solid waste management (MSWM) with local industries, i.e., urban symbiosis, new symbiotic opportunities can be generated from the geographic proximity of urban and industrial areas, transferring physical resources from urban refuse directly to industrial applications and improving the overall eco-efficiency of the city as a whole. Using a case study of Kawasaki, this paper simulates and evaluates an innovative waste management initiative in Kawasaki by an scenario simulation model based on the LCA approach. Results show that recycling mixed paper, mixed plastics, and organic wastes and utilizing the recycled materials in industrial production will potentially reduce about 69 kt CO2(e) emissions and 8 kt incineration ashes to be landfilled in 2015. To achieve these outcomes, the total additional cost compared with the current practice is about 1.2 billion JPY.  相似文献

Finland is a forested country with a large export oriented forest industry. In addition to domestic forest extraction, roundwood is imported, thus displacing the environmental impacts of harvests. In this paper, we analyse the international carbon flows of forest industries in Finland from a consumption-based perspective. Quantitative analyses are available on trade embedded emissions of CO2 from fossil fuel combustion, and here we address in a similar way the impact of trade on the carbon budget of the forest products sector in Finland. Carbon flows through the forest industry system increased substantially between 1991 and 2005. We show that the annual carbon balance related to forests and forest industry system in Finland functioned as a sink in 1991, whereas in 2005 the system was a sink on a national level, but not on a global level. Through calculating the carbon content in traded forest industry products and emissions embodied in forest industry activities, we further show that the direct impacts of the forest industry in Finland are only a minor fraction of the total CO2 emissions related to Finnish production. Nearly all of the emissions were caused due to production of exports. Yet, direct carbon dioxide emissions of the industrial production are reported to Finland in the production based inventories.  相似文献
