Asher Kiperstok, Karla Esquerre, Ricardo Kalid, Emerson Sales, Geiza Oliveira
Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.45058
Abstract:

The instruments developed by the Clean Technology Network of Bahia (TECLIM) at the Federal University of Bahia (UFBA) (cited in Part 1 of this paper) are presented. Factors regarding water management in industry were examined, on the basis of experience acquired over the period of a decade in cooperative research projects with large industrial process plants located mostly in the Camacari Petrochemical Complex, Bahia State, Brazil. The main results consist of training about 1700 industry professionals in CP, the identification of about 500 ideas for the rationalization of water use, the presentation and publication of 90 articles in journals, conferences and other academic events, identification of ideas with potential water savings estimated at around 1400 t·h1 and the reduction of at least 500 t·h–1 in effluents. Other sectors that make use of water, for example public buildings, commercial buildings, homes, shopping centers and airports can adapt and use the TECLIM method as will be exemplified.

Rationalizing the Use of Water in Industry—Part 1: Summary of the Instruments Developed by the Clean Technology Network in the State of Bahia and Main Results Obtained  [PDF]

Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.45057
Abstract:

Based on cleaner production concepts, a method for water use minimization has been developed by the Clean Technology Network of Bahia (TECLIM) at one of the largest industrial complexes in Latin America located in the State of Bahia, Brazil. This method is concerned with an area of secondary interest to the productive sector: the use of water. Based on the best cleaner production principles (CP), nine instruments have been developed during cooperative projects with chemical, petrochemical and copper metallurgical industries. These instruments are described in Part 2 of this paper [1]. The main benefits derived from partnership schemes include: a reduction in water consumption and effluent generation; the development of a techno-operational culture to increase eco-efficiency; and the introduction of conceptual projects to ensure the continuity of the activities in the company after the projects have been completed. The specific consumption of water was reduced by 20% as a consequence of the application of this method in Company A; a specific reduction in the generation of effluents of more than 40% was observed in Company B; a 42% fall in fresh water consumption in Company C; and a 20% decrease in the cost of effluent treatment in Company D. Among the difficulties encountered were the limited time availability of the operators and engineers for the project, the lack of measurement and calibration of available flow meters and the lack of detailed technical data.

Odour Prevention at Biodiesel Fuel Producing Enterprises
Kristina Montrimaite,Asta Maryt? Lapinskien?
Environmental Research, Engineering and Management , 2012, DOI: 10.5755/j01.erem.59.1.676
Abstract: Gaseous, unpleasant, pungent and even harmful odour frequently leads to complaints and appeals to the authorities. For this reason an environmental review was carried out in a certain biodiesel fuel production enterprise, odour pollution sources were identified, their quantities estimated and their impact on the environment assessed. Following the initial environmental review, significant environmental aspects of biodiesel fuel production processes were evaluated. It was found that in technological processes of heating and pressing oil, triglycerides disintegrated in aromas causing discomfort. In order to reduce this impact, the appropriate economic management method and odour removal equipment are to be chosen. When solving this problem it is suggested to install biofilters - activated carbon adsorbers with a stationary adsorber layer and probiotics. In order to choose the adsorber, a calculation method of adsorber technical parameters has been developed in accordance with literature data. The proposed preventive odour reduction means and feasibility of their technical and economical application have been analysed. DOI: http://dx.doi.org/10.5755/j01.erem.59.1.676

I. Budak,B. Kosec,M. Sokovic
Journal of Achievements in Materials and Manufacturing Engineering , 2012,
Abstract: Purpose: During the last couple of decades, development of medical science has been marked with an ever more pronounced interdisciplinary character which, in part, can be attributed to various engineering applications. Rapid development of computer-aided technologies, which completely transformed production engineering, also left an indelible mark on dental prosthetics. Striving towards its primary goal - primum non nocere (’Above all, do not harm!’), the area of dental prosthetics has introduced numerous novel technologies and methods which allow manufacture of precision, custom-made, optimal dental replacements.Design/methodology/approach: The aim of research - to contribute to integration of modern engineering technologies and computer-aided systems into dental prosthetics with special emphasis on efficient manufacture of dental replacements with precision which allows clinical applicability. The subject scope of the paper comprises modelling, manufacturing with special emphases on materials, quality inspection and environmental impact assessment (cleaner production).Findings: In the industrially developed countries, efforts have been concentrated towards advancement of modelling and manufacture of dental replacements by introducing modern computer equipment and state-of-the-art materials and machining technologies. However, in countries in transition, dental replacements are predominantly manufactured in a traditional, manual way prone to errors. The reasons for this situation are various.Practical implications: It is expected that this trend will have a significant impact on the further development of production engineering techniques and technologies in the near future.Originality/value: The paper evolved on the premise that there is a room for more intensive co-operation between the two disciplines - dental prosthetics and engineering, with a prospect for success of the development of novel, original solutions. In that sense, this paper should serve to both professions – production engineers and dentists.
Wastewater Pollution Abatement in China: A Comparative Study of Fifteen Industrial Sectors from 1998 to 2010  [PDF]

Abstract: This study analyzes the management of wastewater pollutants in a number of Chinese industrial sectors from 1998 to 2010. We use decomposition analysis to calculate changes in wastewater pollutant emissions that result from cleaner production processes, end-of-pipe treatment, structural changes in industry, and changes in the scale of production. We focus on one indicator of water quality and three pollutants: chemical oxygen demand (COD), petroleum, cyanide, and volatile phenols. We find that until 2002, COD emissions were mainly reduced through end-of-pipe treatments. Cleaner production processes didn’t begin contributing to COD emissions reductions until the introduction of a 2003 law that enforced their implementation. Petroleum emissions were primarily lowered through cleaner production mechanisms, which have the added benefit of reducing the input cost of intermediate petroleum. Diverse and effective pollution abatement strategies for cyanide and volatile phenols are emerging among industries in China. It will be important for the government to consider differences between industries should they choose to regulate the emissions of specific chemical substances.
