  • Recovering Wasted Energy: Beneath the city streets

    Sewage heat recovery graphNo one likes to think about it, but city planners and engineers often have no choice but to deal with it, and that’s sewage. Though techniques vary somewhat from place to place and from facility to facility, sewage generally flows down pipes with multiple steps in place designed to remove and treat as many solids as possible, before returning the freshly distilled ...

  • Shredding tyres stops zika virus breeding

    Zika is a dangerous disease threatening millions of people today in southern hemisphere. It is spread mostly by the bite of an infected Aedes species mosquito (Ae. aegypti and Ae. albopictus). These mosquitoes bite during the day and night. Once you get bitten it is too late to do much but what is important is to prevent this mosquito from breeding. Mosquitos typically lay eggs near water because ...

  • Recovering oil from grinding sludge - Case Study

    Zahnradfertigung Ott uses RUF briquetting unit A large volume of sludge is produced in the grinding of high-precision gears. In most cases, this grinding sludge is disposed of at high costs. Zahnradfertigung Ott, a specialist manufacturer of gears, found a better solution: since 2005, the company is using a briquetting unit from RUF to recover 500 litres of grinding oil per day from the ...

  • Automotive Manufacturer Achieves Zero-Liquid-Discharge Production, Recovers Waste Energy - Case Study

    An automotive manufacturing plant in Morocco, consisting of pressing, body assembly, paintwork, and final assembly, started-up in early 2012 with two new production lines and an annual output capacity of 400,000 vehicles/year. The site was designed to discharge zero industrial effluents to the environment. Water consumption for manufacturing processes are 70% lower than for a conventional plant ...

  • A methodological proposal for the identification of energy-environmental performance indicators aimed at recovering the air quality

    The paper deals with the introduction of a complex index capable of evaluating environmental air quality in industrial areas. In Italy regional plans of recovery and protection of air quality have been put in practice in order to identify areas where the increase of the emissions into atmosphere, owing to urban and/or industrial development, should be limited or prevented. The methodology is ...

  • Recovering and extending classical and Marshallian foundations for post-Keynesian environmental economics

    Post-Keynesians emphasise the critical roles of institutional structures and production in economic life. An assumption of the plasticity of production has led to the neglect of the underlying physical and ecological requirements of production and the dependence of human economies on nature's resources and production. The task of developing an environmental economics cannot be separated from the ...

  • Oil grabber® model 8 recovers 70% of quench oil

    An oil skimmer for use on heated spray wash tanks in a Midwestern heat treating firm has enabled the company to recover 70% of their quench oil from the washing solution, materially aiding their energy conservation program. Recovery and recirculation of 70 % of the quench oil is considered an exceptionally high level of efficiency according to Mr. James Reh, Plant Engineer for Lindberg Heat ...

  • Can towns near Japan`s Fukushima nuclear plant recover?

    A few signs of life are returning to this rural town made desolate by the Fukushima nuclear disaster four-and-a-half years ago: Carpenters bang on houses, an occasional delivery truck drives by and a noodle shop has opened to serve employees who have returned to Naraha's small town hall. But weeds cover the now rusty train tracks, there are no sounds of children and wild boars still roam around ...

  • Towards a desalination initiative using cogeneration with an advanced reactor type and uranium recovered from Moroccan phosphoric acid production

    Morocco is known to be among the first few countries to produce phosphate and phosphoric acid. Moroccan phosphate contains substantial amounts of uranium. This uranium can be recovered from the phosphate ore as a by-product during the production of phosphoric acid. Uranium extraction processes linked with phosphoric acid fabrication have been used industrially in some countries. This is done ...

  • On site flotation for recovering polluted aquatic systems: is it a feasible solution for a Brazilian urban river?

    Pinheiros River (Brazil) plays a pivotal role in supplying water to Billings Reservoir, which presents multiple uses (human drinking, energy generation, irrigation, navigation, fishing and leisure). An intense monitoring program was performed during the years 2007 and 2008 to find out whether on site flotation is a feasible solution or not for improving the water quality of this urban river, ...

  • Footwear to Energy

    In developing countries within South East Asia, ever-depleting landfill space, fast-growing populations and an increasing need for more concrete to build, are just some of the factors that make for a compelling alternative fuel production argument. But to what extent is a lack of waste infrastructure holding such countries back? Is legislation the missing ingredient? Or do global brands need to ...

  • About Energy

    ©2010 Florian Ion PETRESCU - Obtaining Energy by the Annihilation of an Electron with a Positron. We can extract the energy of the rest mass of an electron. For a pair of an electron and a positron this energy is circa 1 MeV. The "synchrotron radiation (synchrotron light source)" produces deliberated a radiation source. Electrons are accelerated to high speeds in several stages to ...


  • Gasification - The Waste-To-Energy Solution

    Introduction Each year, Americans generate about 250 million tons of Municipal Solid Waste, or MSW—about 4.3 pounds per person per day. This includes “trash” such as kitchen waste, electronics, light bulbs, plastics, used tires and old paint, and yard waste. Despite significant increases in recycling and energy recovery, only about one-third of the total MSW is ...

  • Landfills Expand Energy Output

    HIGH fossil fuel prices and growing concern about global climate change are creating favorable conditions for landfill gas energy (LFGE) projects. Notably, endorsement of LFGE by Federal agencies and many states as a form of “green” power has enabled LFGE developers to earn premiums for electricity marketed through green power programs, and to benefit from expanded federal tax credits for ...
