浅析电镀行业的清洁生产措施

随着科学技术与生产的发展,电镀所涉及的领域越来越广。已经遍及人们生活的各个方面。但是电镀生产污染令人担忧,据统计,我国每年排出约4亿吨重金属废水,5万吨废渣。酸雾3000万立方米。更严重的是,一些重金属,如铅、隔、铬通过土壤吸收后进人庄稼内,人食用后会在人体内造成积累性中毒或致癌。因此电镀行业的清洁生产就成为当务之急,这也符合国家的节能减排政策,符合电镀工业的可持续发展。     

Quantitative evaluation of cleaner production and environmental policy toward the co-benefit of greenhouse gas and odor reduction: case study of Tapioca starch industry

Chemical components of airborne volatile organic compounds (VOCs) released from a wastewater treatment system of the tapioca industry were identified. Quantitative analysis of the concentrations and the emissions of each chemical were evaluated taking into consideration the difference in atmospheric turbulence over the surface of the wastewater during the day and the nighttime periods. The chamber experiments were performed on-site in order to reflect actual environmental characteristics of the study area. Chemical concentrations were analyzed following the U.S. EPA TO-15 Standard Method. Emissions of each compound were calculated using the box model scheme. It was found that acetaldehyde and acetone were two major compounds of released airborne VOCs from the wastewater treatment system of the tapioca industry. Due to its high organic content, the wastewater treatment facilities of this type of factory generally caused the odor problem to its surrounding communities. These data were then used to evaluate the success of implementing the Clean Development Mechanisms project in this industry. Reduction in the affected area from odor by improving the wastewater treatment system from opened lagoons which is the type of common practice in most of the tapioca factories in the developing countries to the modified covered lagoons was evaluated. These results supported the theory of the co-benefit of managing both local environmental problems and reduction of greenhouse gas emissions from the implementation of cleaner technology in the agro-industry. This methodology can be applied to reveal and quantify the success of other green efforts particularly in the agro-industry businesses.

An AHP-based water-conservation and waste-reduction indicator system for cleaner production of textile-printing industry in China and technique integration

The textile-printing industry in China makes an important contribution to the national economy. However, the associated pollution problems have caused gradual deterioration to the environment and adverse impacts on the local community. The indicator system of cleaner production gives a powerful tool to measure the level of cleaner production of textile-printing enterprises. In China, it has been a big problem of the textile-printing enterprise that consuming large amounts of fresh water and discharging large number of pollutants, and it is lacking in a scientific water-conservation and waste-reduction cleaner production evaluation system. To solve such problems, the establishment of water-conservation and waste-reduction cleaner production indicator system in textile-printing industry is proposed and assessed by the means of analytic hierarchy process (AHP) in this article. The judgement matrix is then determined with the Delphi Method combined. Finally, with the Yaahp software, the weight of each indicator is obtained. As an effective way to save water resource and reduce waste emission, the cleaner production technique integration is provided for the enterprises to solve the above problems and achieve the goals of saving water and decreasing the amount of disposed pollutants.     

Using FANP approach on selection of competitive priorities based on cleaner production implementation: a case study in PCB manufacturer,Taiwan

The aim of this paper is to identify and discuss some of the important and critical decision criteria including cleaner production implementation of an efficient system to prioritize competitive priorities. Fuzzy analytic network process (FANP) based methodology is discussed to tackle the different decision criteria involved in the selection of competitive priorities in current business scenario. FANP is an efficient tool to handle the fuzziness of the data involved in deciding the preferences of different decision variables. The linguistic level of comparisons produced by the professionals and experts for each comparison are tapped in the form of triangular fuzzy numbers to construct fuzzy pairwise comparison matrices. The implementation of the system is demonstrated by a problem having four stages of hierarchy which contains different criteria, attributes and alternatives at wider perspective. The proposed model can provide a hierarchical framework for the cleaner production implemented organization to select on its competitive priorities.     

Modelling hybrid production systems through the ACD specification: a case study in the fibre-glass industry

This paper is aimed at formalising a model for hybrid production systems where the interactions between the continuous process parts and the manufacturing sub-systems are given by minor stoppages. The proposal is to represent the effects of the continuous process dynamics on discrete manufacturing sub-systems using autoregressive conditional duration (ACD) models originally conceived to treat high-frequency and irregularly spaced financial transaction data. The proposed methodology has been tested on a real-life fibre-glass production plant exploiting simulation techniques. The physical model of the furnace and spooling-bushing department has been run in two different conditions: (i) the fibre-glass breakings, i.e. minor stoppages, on the spooling-bushing machines are generated according to the proposed approach; (ii) historical fibre-glass breakings data are used. The comparison between the simulation results shows that for three spooling-bushing machines only out of 24, the daily throughput of completed spools and the empirical distributions for the uncompleted spools weight are dissimilar under the two different conditions. Therefore, the ACD-based model proved useful for representing the occurrence of fibre-glass breakings on the spooling-bushing machines and, in more general terms, for the logical modelling of the hybrid production systems, where the relationships between continuous and discrete parts are given by minor stoppages.

The distinctive patterns of capabilities accumulation and inter-firm heterogeneity: the case of the Spanish pharmaceutical industry

This paper examines the extent to which systematic differencesin performance across firms can be explained by the differentsets of capabilities mastered by firms. Cluster analysis isused to group firms based on the degree of capability accumulationalong three dimensions: manufacturing, R&D and marketing.Sixty-seven Spanish domestic pharmaceutical firms are studied,focusing on the period 1990–1997. Our findings indicatethat five clusters can be identified. Firms with better performanceindicators are those that manage to generate capabilities thatare uncommon among competitors—particularly capabilitiesin product development.
