This study was performed to assess particulate matter removal efficiency of domestic air cleaner products in afield condition. The assessment also included air cleaners with different air removal mechanisms. The particulatematter (PM2.5) removal test with a different air removal mechanism using air cleaners showed that the electrostaticprecipitation technique showed better performance compared with HEPA filters and other types of systems. Itsremoval efficiency was almost 95% in one of our operation times in the given test condition. It was assumed thatnot only the type of removal system but also the individual design, supply and exhaust system, and theautomatically controlled air volume are involved in the removal efficiency. With respect to the area of application,tests with air cleaners for 40 m2, 60 m2, and 80 m2 areas revealed that particulate matter removal efficiencyincreased with the air cleaner that had a broad area of application. However, particulate matter removal efficiencyby air cleaners did not correspondingly increase with the increase of the area of application. Moreover, theinstallation location did not influence particulate matter removal efficiency. Our results are expected to be usedas the basic information for indoor air quality improvement and prediction using air cleaners.

Cleaner production have different names in different stages of development or in different countries, such as waste minimization, non-waste technology, pollution prevention and so on. Cleaner production refers to that the comprehensive prevention strategies for environmental protection are continuously applied to the production process and products in order to reduce the risk to human and the environment. Cleaner production in essence is a mode of production, which takes the overall preventive environmental strategy to processes and products and reduce or eliminate the harm they may bring to human and environment, while fully satisfy human needs to maximize socioeconomic benefits. In 1994, the Chinese government list cleaner production as one of the key projects in the Chinese 21st Century Agenda. In 2002 formulated the Cleaner Production Promotion Law, and revised the law in February 29, 2012. In addition, local governments also formulate local cleaner production promotion ordinance in turn according to the provisions of Cleaner Production Promotion Law. So far, China has formed a relatively complete cleaner production -related legal system, but cleaner production in some areas still need to be further improved and standardized.

Minquan Ye,Jingyi Sun,Shenhai Huang 대한환경공학회 2019 Environmental Engineering Research Vol.24 No.4

In order to alleviate the environmental pressure caused by production process of thermal power plants, the application of cleaner production is imperative. To estimate the implementation effects of cleaner production in thermal plants and optimize the strategy duly, it is of great significance to take a comprehensive evaluation for sustainable development. In this paper, a hybrid model that integrated the analytic hierarchy process (AHP) with least squares support vector machine (LSSVM) algorithm optimized by grid search (GS) algorithm is proposed. Based on the establishment of the evaluation index system, AHP is employed to pre-process the data and GS is introduced to optimize the parameters in LSSVM, which can avoid the randomness and inaccuracy of parameters’ setting. The results demonstrate that the combined model is able to be employed in the comprehensive evaluation of the cleaner production in the thermal power plants.

Assessing the environmental impacts of product systems has become critical, with emphasis on reducing carbon dioxide emissions in line with the new climate change regime. Accordingly, environmental regulations have been newly issued or have stronger requirements for inducing more energy-efficient and environmentally-conscious product development. Therefore, product developers in new product development are being forced to consider various and heterogeneous design performance and are encountering more difficulty and chaos when selecting the best product design among design candidates. The relevant studies have contributed to providing tools and techniques for increasing the environmental soundness of the product; however, they do not holistically accommodate the quantification of functional and economic metrics, nor do they incorporate the compliance with recent environmental legislations. The present work proposes an environmentally-conscious design method that integrates functional, economic, and environmental assessments with the compliance of the energy-related products (ErP) legislation. This method provides analytical capabilities including: (1) a functional assessment to derive the durability of the product to be embedded for practical measurement in the following assessments, (2) a compliance check to ensure that energy-related products fulfill the ErP directive enacted by the European Union, (3) an economic assessment to calculate the total cost during the product lifecycle by using the life cycle cost concept, and (4) an environmental assessment to quantify the environmental loads of the product by using a simplified life cycle assessment. The present work also includes a case study to demonstrate the effectiveness of the proposed method; to this end, two different electronic vacuum cleaners are compared. The results of the present work help product developers use life cycle design thinking for determining their design parameters by checking their compliance with the ErP legislation and assessing economic and environmental metrics with a mechanical analysis of the durability of product systems

Recently, environmental problems, such as climate change, greenhouse gas, and etc, are spreading out world-wide. Moreover environmental management is on the rise as a significant issue in securing enterprises` competitiveness and establishing strategy of green growth. The purpose of this study is enhancing manufacturing business`s ability in SCEM (Supply Chain Environmental Management) and suggesting strategic direction of environmental management through literature study and demonstration study which are about how green purchasing which is variable of SCEM, cleaner production technology, and reverse logistics bring positive effects on business performance which is distributed in environmental performance and non- environmental performance. The result of this study transportation innovation and reverse logistics affect greenhouse gas, harmful materials and resource decrease positively upon environmental performance as it was described in the previous research. However, green purchasing and cleaner production technology was turned down. But, non-environmental performance, such as images of company, enhancement of product quality, raising customers satisfaction are influenced in positive way by green purchasing, cleaner production technology, reverse logistics. Nevertheless, it was dismissed. Such study result requires role as a part of supply chain which logistics of individual companies from logistics centric process to procurement, production, sales and reverse logistics integrate with regional collaboration. Also, transportation innovation, such as de-transportation, becoming bigger, rationalization, model shift, and so on, gives positive influence to ``environmental performance`` but it doesn`t affect much in raising ``non-environmental company performance`` such as the image of company, customer satisfaction, quality improvement and so on. Therefore, it previewed that they should propulsion ``Sustainable strategic management`` to an outcome of the company with using environment soundness and economic profitability of SCEM, that investigate the responsibility of the society.

<P><B>Abstract</B></P> <P>The effectiveness of a surface dielectric barrier discharge (DBD) reactor was evaluated over a range of relative humidiy (RH), discharge areas and applied powers. Primary goals included maximizing toluene decomposition efficiency and CO<SUB>2</SUB> selectivity while maintaining a high specific energy density and energy yield. Humidity was a limiting factor, although it did not significantly increase the energy efficiency of the system. A RH of 20% was found to be optimal for toluene abatement, and large discharge areas decreased the energy yield by increasing the rate of power consumption. At a frequency of 60 Hz and an applied voltage of 4.3 kV, 8.4, 6.4 and 4.3 g/kWh of toluene was removed at discharge areas of 215, 430 and 645 cm<SUP>2</SUP>, respectively. Energy efficiency was also reduced at high applied power by ozone formation in the reactor.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
