Accelerating preliminary eco-innovation design for products that integrates case-based reasoning and TRIZ method

While the innovativeness and market potential of a new product is normally emphasized, its environmental impact is often neglected. Despite their ability to help designers reduce the environmental impact of products throughout their life cycle, many eco-design methods focus on the redesign of existing products, necessitating a more innovative design capacity. This work describes a novel model to accelerate the preliminary eco-innovation product design by integrating the advantages of case-based reasoning and the TRIZ method. Previous cases from a database support a novel design to satisfy functional performances under the CBR framework. The innovative principles and evolution patterns of the TRIZ method can enhance the design level of new products to achieve eco-innovation. Four eco-innovation concepts for a PC mouse demonstrate the effectiveness of the proposed model.     

轻型汽车和汽车塑料配件涂装工艺过程的VOCs组分特征

通过采集和分析珠江三角洲(以下简称“珠三角”)地区轻型汽车和汽车塑料配件涂装工艺过程的VOCs样品,识别了上述两个行业不同涂装工艺过程的VOCs组分特征.结果表明:芳香烃(56.4%~75.5%)和OVOCs(11.0%~35.7%)为轻型汽车涂装工艺占比最大的两种VOCs组分;烷烃和烯炔烃在烘干工艺所占比重要高于喷涂工艺;1,2,4-三甲苯为电泳和面涂烘干工序的主要VOCs组分,间/对-二甲苯、乙酸丁酯、丙二醇甲醚醋酸酯分别为中涂、面涂和中涂烘干工序的主要VOCs组分.汽车塑料配件涂装工艺不同工序的VOCs组成相似,芳香烃(53.3%~58.3%)和OVOCs(40.9%~45.8%)为主要VOCs组成,甲苯、乙酸乙酯、乙酸丁酯等为主要VOCs组分.不同废气治理设施对汽车塑料配件涂装工艺VOCs组分会造成一定的影响.活性炭吸附治理设施处理后的主要VOCs组分为甲苯、乙苯和邻二甲苯等芳香烃组分,水喷淋治理设施则为乙酸乙酯、乙酸丁酯和丙二醇甲醚醋酸酯等OVOCs类组分.通过与其他研究对比,丙二醇甲醚醋酸酯作为原辅料和废气中的主要组分之一,在以往研究中并未识别出来,表明针对测试对象的原辅料与工艺信息的现场调研是开展VOCs组分特征及成分谱研究的基础工作,建议未来该方面研究加强对前期调研工作的重视.此外,建议关注行业发展趋势给VOCs成分谱研究带来的影响.     

Climate change adaptation in the ski industry

Regardless of the success of climate change mitigation efforts, the international community has concluded that societies around the world will need to adapt to some magnitude of climate change in the 21st century. While some economic sectors (e.g., agriculture, water resources and construction) have been actively engaged in climate change adaptation research for years, adaptation has received scant consideration within the tourism-recreation industry. This is particularly the case for adaptation by tourism operators (supply-side). One exception where progress on supply-side climate adaptation has been made is the ski industry. This paper provides a brief overview of the literature on the implications of climate change for the international ski industry and how adaptation by ski area operators has been treated within these studies. This is followed by an inventory of climate adaptation practices currently used by ski industry stakeholders, including the historical development of certain key adaptations and constraints to wider use. The characteristics of ski areas with higher adaptive capacity are identified. Considering the highly competitive nature of the ski industry and the generally low climate change risk appraisal within the industry, climate change adaptation is anticipated to remain individualistic and reactive for some time. With only a few exceptions, the existing climate change literature on winter tourism has not considered the wide range of adaptation options identified in this paper and has likely overestimated potential damages. An important task for future studies is to develop methodologies to incorporate adaptation so that a more accurate understanding of the vulnerability of the international ski industry can be ascertained.

Environmental improvements in the metal finishing industry in Australasia

Metal finishing, as an industry, has had a vexed history with the environment and regulatory authorities over many decades throughout the world. Over the past 20 years, this situation has been vastly improved in some developed countries. This paper will examine the industry's recent progress in Australasia and highlight specific issues including new technologies adopted, research projects undertaken, responses to Government legislation and education. Many toxic chemicals have been replaced, recycled in closed loop scenarios and prevented from entering the environment via the atmosphere, water ways or landfilling. This paper is written as a qualitative industry summary rather than an academic study. It is meant to highlight the major changes that have occurred and the reasons why, rather than present documented and detailed evidence. The author has drawn on his 35 years experience in the industry as well as many experienced colleagues from around the world. Although the geographic scope is Australasia, many comments emanate from the state of Victoria because it is still the manufacturing base, especially in relation to the auto industry that has affected the changes to a large degree.     

The intermediary role of an industry association in policy-making processes: the case of the Dutch paper and board industry

In the policy-making process concerning energy and environmental issues, cooperation between government and firms is a means to create a more efficient energy and environmental policy. Intermediary organizations can play an important role in this policy-making process. Aim of this study is to get insight into the role of one specific intermediary organization: the industry association. In this paper, we focus on the Dutch paper and board industry. Important policy themes for this industry are waste water, waste, and energy efficiency. We distinguished four types of governmental policy instruments: top-down regulation, interactive regulation, negative economic instruments, and positive economic instruments. We analyzed the role of the industry association in the policy-making process for all of these four instruments. The results clearly show different (relative) roles of the industry association in different steps of the policy-making processes and for different types of instruments.

Promoting cleaner production in the Indian small-scale mining industry

India is among the top ten mineral producing nations in the world and its economy depends on the value of minerals produced. Although mineral production has increased significantly since the country’s independence, what continues to be overlooked in is the contribution of resident small-scale mines to national mineral output. Approximately 90% of India’s mines are operating on a small-scale, employing some 0.5 million people. However, because of their rudimentary and highly migratory nature, these operations feature poor environmental management practices and safety conditions. This paper examines the unique techno-economic and socio-cultural characteristics of selected small-scale mining regions in India. It furthermore underscores the need for cleaner production in these regions, and outlines a series of legislative measures pertinent to the industry. The paper concludes by identifying educational- and training-related initiatives, which, if undertaken, could facilitate additional environmental improvement at sites.

Clean technology for the tapioca starch industry in Thailand

The tapioca processing industry is considered to be one of the largest food processing industrial sectors in Thailand. However, the growth of the tapioca starch industry has resulted in heavy water pollution as it generates large amount of solid waste and wastewater with high organic content. This study explores the applicability of clean technology options to improve the environmental performance of tapioca starch-processing plants in Thailand. Eight Tapioca starch plants were selected for an exclusive analysis of the dynamics of clean technology development and adoption. Proposed options mainly involve water reduction and energy conservation. These include reuse and recycling of water, technology modification in the production process, and use of biogas to substitute fuel oil for burners. Implementation of these proposed alternatives to real companies shows that the reduction of starch loss, and water and fuel cost savings can be achieved.

New approaches to pollution prevention in the healthcare industry

Since the 2000 inception of “Hospitals for a Healthy Environment” (H2E)—a US Environmental Protection Agency and American Hospital Association pollution prevention partnership—the healthcare industry has made a concerted effort to eliminate mercury and reduce other toxics.The Minnesota Technical Assistance Program (MnTAP), at the University of Minnesota, used H2E tools over the course of two years (2001–2003) to demonstrate the effectiveness of pollution prevention at healthcare facilities. As a result at least 22% of Minnesota hospitals are engaged in documented pollution prevention efforts. Twenty-nine facilities have eliminated 75% of their mercury or are working towards that goal. MnTAP was able to document healthcare facilities that have eliminated 394 lb of mercury, 751 gal of hazardous chemicals and 250,000 lb of solid waste, saving $152,600. MnTAP continues to provide pollution prevention assistance to the healthcare sector.     

On zero water discharge solutions in the process industry

This paper presents a mathematical programming approach to analyze the feasibility of zero liquid discharge option in different industries. Mathematical programming methodologies are applied to four industrial cases—a tricresyl phosphate plant, an ethyl chloride plant, a paper mill and a refinery. In each case study various end of pipe and regeneration configurations using different treatment technologies are explored to determine the possibility of zero liquid discharge and its economical feasibility. The results show that the relationship between the cost of regeneration and the cost of freshwater as well as the discharge concentration of the treatment is the determining factor for the feasibility of zero liquid discharge.

Process modification in the scouring process of textile industry

The effects of scouring parameters on the scouring efficiency, including the weight ratio of de-sizing agent and fabric (5–80 g/g fabric), temperature of de-sizing agent tank (60–90 °C) and dipping time (2–8 s), were investigated. The results demonstrated that weight loss of sizing agent was significantly observed only in the de-sizing agent tank particularly in the first de-sizing tank and was found to a small extent in water tank. The optimum condition in the scouring machine was found at a de-sizing agent to fabric ratio of 20 g/g fabric, with a temperature of the first de-sizing agent tank of 80 °C, a temperature of the second de-sizing agent tank of 90 °C, and dipping time of fabric of 7 s. According to these conditions, more than 89% of the sizing agent was eliminated and only 3.52 mg/g fabric of sizing agent remained in the scoured fabric which was in an acceptable range for feeding to the down stream process known as dyeing process. Application of our results to actual textile plant has shown that there is a cost reduction due to improved utilization of rinse water, chemicals and energy in the process and consequent decreases in the generation of wastewater. Furthermore, the production capacity was increased from 30 m/min to 34.4 m/min.     

Technological options for waste minimisation in the mining industry

Just as the application of technology in mining processes can cause pollution, it can also be harnessed to minimise, and sometimes eliminate, mine-related contaminants. Waste minimisation can be achieved through decreased waste production, waste collection, waste recycling, and the neutralisation of pollutants into detoxified forms. This article reviews examples of how technology can be used to minimise air, water, land and noise pollution in the mining industry.     

Flowsheeting-based simulation of recycling concepts in the metal industry

This paper presents a methodology for the planning of integrated recycling concepts taking into account the peculiarities of process engineering in the process industries. Process models for certain unit operations simulated with a flowsheeting program allow to calculate mass and energy balances considering the technical characteristics and performance of a single process or a combined process chain. Based on principles of thermodynamics, this approach allows an assessment of integrated recycling strategies considering techno-economic as well as ecological criteria. The approach is illustrated with an example from the iron and steel making industry where the injection of plastic waste into a blast furnace is investigated.     

Ecoprofit-Styria-prepare Thirteen pollution prevention case studies in the Styrian industry

The paper focuses upon the organization of a federal state-funded pollution prevention project in the Styrian industry. The project includes 13 companies from the textile, pulp and paper, machine building, wood working and printed circuit board manufacturing industries, covering most of the sectors and sizes in the Styrian industry. It started in January 1994 and will last for one year. It will demonstrate the possibilities of pollution prevention and the need for further research work. This project will make use of the methods and tools that were refined in the Austrian Prepare project. As a first step, a systematic balance of all the inputs and outputs of a company is made, after which the weak points and inefficiencies of material and energy use are identified and the options for improvements, both economical and ecological, are defined. Consequently, modifications in products and production lead to a situation with less waste and emissions. The preliminary lessons from these projects are presented: as a rule, the utilities (consumption of process materials and water, cleaning, energy, preparatory and finishing steps) are treated as black boxes and usually represent a considerable optimization potential. In these areas especially there is usually a lack of information and coordination as well as a need for a systematic and comprehensive approach. Leadership in the company and creative consultants are needed for starting lasting successful pollution prevention projects.
