Industrial ecology (IE) is an emerging framework adopted in the manufacturing, construction, and process industries to provide innovative solutions in strategic planning, leading to cleaner operation and production. An IE framework integrates a large number of processes, economic constraints, and environmental, health and safety considerations for optimized resource utilization. This paper provides a review of environmental management practices in the mining and minerals industry, emphasizing two concepts: IE and cleaner production. The mining and minerals industry provides primary materials for industrial activities; as such, it is an important component in the “industrial ecosystem.” This industry is subject to very stringent social and environmental scrutiny, while providing society with required natural resources to meet essential sustainable development requirements. The implementation of an IE framework in the sector will contribute to sustainable development. 相似文献

The clean development mechanism (CDM), one of three flexible mechanisms of the Kyoto Protocol, has received noticeable attention
in cement industry in china. In this paper we will discuss in past the utilization ratios of waste heat generated in cement
industry are at low level in China and at present it is at high level and how the CDM contributes to upgrade cement industry
structure. Making fully use of the opportunity brought by clean development mechanism can help cement enterprises in china
to recover the waste heat generated in the process of cement production. Implementing the development of clean development
mechanism projects in cement industry field, mainly focusing on waste heat for power generation projects, can not only reduce
environmental pollution, but also bring certain economic and social benefit. It is in favor of promoting the upgrade of cement
industrial structure, and will contribute to positive and far-reaching effect toward sustainable development of cement industry
in China. 相似文献

State and federal governments in Australia have implemented a range of assistance programs for manufacturing industries to become more resource efficient and reduce waste. While many of these programs focus on Cleaner Production at single sites, an increasing number of assistance programs are offered across supply chains. Sustainability Victoria, a Victorian government authority, supports projects that focus on resource efficiencies across supply chains in key industry sectors.In this study, tools were adapted and utilised to identify efficiency potentials and losses across supply chains in the timber furniture manufacturing and the food industry sector. In this respect, waste generation and value loss due to inefficient use of critical materials within the processes were estimated from purchase and waste handling data. Primary companies were chosen to undertake efficiency trials that could demonstrate value gain across the supply chain.This study describes the realisation of greater efficiencies in material usage when engaging proactively with supply chain partners immediately adjacent to the primary company. Demonstration trials confirmed that through a more integrated approach among supply chain partners the potential in using materials more efficiently and design processes can lead to enhanced productivity without compromising environmental burden. Hence, the study describes targeted resource efficiency, recycling and process optimisation opportunities as identified in the supply chain trials on timber furniture manufacturing and food industries. 相似文献

This paper mostly deals with the role of energy, matter and information flows within both environmental and human-dominated systems. Sustainable growth and development of both kinds of systems require optimum use of available resources for maximum power output, as suggested by Lotka's Maximum Power Principle [Lotka AJ. Contribution to the energetics of evolution. In: Proceedings of the national academy of sciences of the United States of America, vol. 8. 1922, p. 147–50; Lotka AJ. Natural selection as a physical principle. In: Proceedings of the national academy of sciences of the United States of America, vol. 8. 1922, p. 151–5.], recently restated by Odum [Odum HT. Maximum power and efficiency: a rebuttal. Ecol Model 1983;20:71–82; Odum HT. Environmental accounting. Emergy and environmental decision making. N.Y.: John Wiley & Sons; 1996.] as Maximum Em-Power Principle within the framework of his Emergy Synthesis approach. In times of declining resources, this principle translates into increased efficiency and optimum use of any kind of waste and co-products. Ecosystems and any self-organizing systems always apply this strategy and their selection–evolution mechanisms are based on their ability of growing on any untapped resource available. In order to do so, they increase the number of components and patterns for resource degradation in order to optimize the resource throughput and power output. Such a strategy also applies to human-dominated, economic systems, where the ability of dealing with co-products and wastes by means of appropriate designs as well as reuse and recycling processes may lead to “zero-emission” patterns (increased complexity, optimal resource throughput, minimization of emissions, resource exchange among system's components) and be the key for successful and sustainable development. In this paper Life Cycle Assessment and Emergy Synthesis approaches are suggested as joint tools for qualitative and quantitative evaluation of progresses towards industrial symbiosis and more sustainable production and consumption patterns within a zero emission framework. 相似文献

Recycling and reuse of waste such as building rubble, concrete lumps, etc. generated at construction and demolition sites form part of a wider, complex issue, primarily relating to improving supplies of construction material and solving problems of disposal of waste construction material. Within the framework of the sustainable development of the environment, the use of waste materials with minimum environmental impact has received much attention. The conversion of a large amount of demolished waste into an alternative resource will conserve the depleting natural resources of building materials. Demolished waste is mainly used as a non-stabilized base or sub-base in highway construction. The present paper discusses the recycling process and makes an effort to assess a safe and economic use of recycled concrete as a structural grade material for the construction industry. Extensive tests of structural properties such as compressive strength, flexural strength and split tensile strength of recycled concrete were carried out, in which cement and similarly fine aggregate were partially replaced by demolished waste to obtain recycled concrete and recycled aggregate concrete whose properties were compared with results for the conventional concrete. 相似文献

Natural resources are being depleted at faster rates than ever; this highlights the need for global audits and actions to reverse the depletion. Coordinated efforts by various organizations are essential to quantify reserves and demands in such audits in order to enable the development and implementation of strategies for sustainable recovery, usage, and recycling of natural resources. This paper discusses such audits in several industries and puts forward analytical and technical methods and policies for sustainable recovery, usage and recycling of resources in those industries. Scenario analysis can help to provide better future directions for industries whilst eco-industrial parks could improve the efficiency of usage of available resources and waste products through synergies among different industries on a regional basis. Sustainable manufacturing within industries such as micromachining, cement and leather could further reduce consumption of natural resources. New technologies in mineral recovery could help to recover valuable minerals present in concentrates generated by various processes such as reverse osmosis of sea water, chemical processing of minerals, and domestic and industrial wastewater treatments. These areas are discussed in this special issue of the Journal of Cleaner Production. It is imperative that the efforts by various organizations toward sustainable management of natural resources should compliment each other to minimize duplication; furthermore policy makers should play greater roles in developing and implementing policies and procedures to support such sustainable development oriented approaches simultaneously throughout the world in a coordinated and proactive manner for the short and long term future. 相似文献

Nature does not know the term “harmony”. Only humans should be in harmony with nature and artificial production system, particularly industry, should not destroy natural planetary cycles. It is clear that the world's industry and agriculture based on fossil resources exploitation are not sustainable. Harmony means complementary of natural and man-made cycles. However, there is a fundamental difference between industrial chains and biological chains. We can't use absolute analogy between biological chains and industrial chains. Industrial production chains are artificial created by humans. Zero Emissions concept accented that all industrial inputs can be completely converted into a variety of final products and that waste products can be converted into value added inputs for another chain of production or energy supply. In principle ZETS concept eliminates waste problem completely. The manufacturing line can be viewed as integrated technologies and series of production cycles and recycling systems. What is our opportunity to substitute renewable resources for fossil ones? The international climate conference in Kyoto (1997) and others can be regarded as tests for human capacity to cooperate and creatively manage two dominating carbon-rich solar energy conversion products: fossil organic materials and biomass. The former is found in rich deposits and is physically rather homogeneous (oil, gas and coal), whereas the latter is widely dispersed and highly diversified (microorganisms, plants and animals). Those aspects give oil refineries the character of compact cluster of chemical plants, whereas biomass refineries (biorefineries) are just as diverse as their feedstocks (mills for grain- and oilseeds, the food industry, fermentation plants, pulp and paper mills, etc.) This situation can inspire two questions. The first question is how the fossil carbon sources can be utilized without releasing greenhouse gases such as methane and carbon dioxide to the atmosphere. In contrast to products from non-renewable resources, wood materials do not influence the atmospheric CO2 balance. The second question is, when the oil production finally drops, whether clusters of processing units, designed for the upgrading of specific bioresources, can turn out a similar multitude of products as oil refineries do. The answers on these and other questions will be discussed in the context of ZETS using many case studies examples. Integrated ZETS have many advantages and disadvantages, too. 相似文献
