  • Electronics sector looks to tackle tensions in a globalising world

    Recent EU Directives on waste electronic goods and hazardous substances are leading to tensions with developing countries which export equipment. The global electronics supply chain is now forming an important testing ground for a new initiative on sustainable trade and innovation aimed at overcoming accusations of environmental protectionism. The initiative encapsulates some of the conflicts ...

  • Europe ‘s E-waste Failure – Only a Third of Electronic Waste Managed Correctly

    Mismanagement of discarded electronics within Europe involves a volume 10 times that of e-waste shipped to foreign shores in undocumented exports, according to a comprehensive 2-year investigation into the functioning of the used and waste electronics market. The European Union-funded project, Countering WEEE (waste electrical and electronic equipment) Illegal Trade (CWIT), was undertaken by ...

  • Development of modulation strategies for three-phase to two-phase matrix converters

    In this paper, the modulation strategy is developed for three-phase to two-phase matrix converters for synthesising balanced and unbalanced output voltages from balanced and unbalanced input voltages. Reduction of low order input current harmonics with sinusoidal output voltages is achieved by using the proposed switching strategies. The other advantage of the proposed method is the significant ...

  • Biohydrogen production from tequila vinasses using a fixed bed reactor

    In Mexico, the industrial production of tequila leads to the discharge of more than 31.2 million of m3 of vinasse, which causes serious environmental issues because of its acidity, high organic load and the presence of recalcitrant compounds. The aim of this research was to study the feasibility of a fixed bed reactor for the production of biohydrogen by using tequila vinasse as substrate. The ...

  • A longitudinal examination of performance of two ways on innovation in Taiwan: internal R&D investment and external technology aquisition

    While internal Research and Development (R&D) investment and external technology acquisition are the two primary ways adopted by Taiwan's manufacturing firm's for innovation, relatively little research has focused on evaluating the contribution of these two ways of innovation on firm's performance. This study therefore aims to investigate the impact of (1) internal R&D (2) external technology ...

  • An improved method for injection of emulsified edible oils

    A field demonstration of the technology at a former adhesive manufacturing facility is presented. Treatment consisted of creating a permeable reactive barrier (PRB) downgradient of the DNAPL source, and injection of emulsified oil amendment directly into the source area. The primary soil and groundwater contaminants consisted of 1,1,1-trichloroethane (1,1,1-TCA), trichloroethene (TCE), and their ...

  • Japanese Organics Recycling Association Formed

    Another backyard composting adage states that compost should have the feel of a wrung-out sponge — damp but not dripping wet. Actually, a wrung-out sponge may be on the dry side for composting, but the analogy does provide a great image for understanding the reasons for balancing moisture. Like a compost pile (or windrow or material in a vessel), a sponge is a solid mass containing an enormous ...

  • Boiler Dissolved Oxygen Control

    DISSOLVED OXYGEN CHEMISTRY Dissolved Oxygen (DO) is a measure of the amount of oxygen, usually thought of as a gas, that is dissolved in a liquid such as water. Oxygen is essential to life and is also the most common element found taking part in corrosion reactions. DO can be thought of as the fuel needed for the corrosion process to proceed. It is the corrosion reactions that necessitate ...

  • Leak detection in semiconductor fab gas processes

    Problem Statement Often times in semiconductor fabs moisture levels are monitored to ensure that products aren’t damaged by excess moisture in the process. If there are above normal levels of moisture, pinpointing the source of that moisture can be difficult. The moisture could be evolving from impurities in gas tanks or leaks in the sampling lines. One way to avoid downtime ...
