  • Waste materials are an underused resource the construction of Europe`s roads

    Recycled waste material could play a major role in the construction of roads in Europe, bringing both environmental and economic benefits. A new study proposes a scenario where 50% of the asphalt for Europe's roads consists of recycled materials, leading to significant reductions in costs, energy use and greenhouse gas emissions. According to the European Waste Framework Directive, there is a ...

  • India’s Potential in Harnessing the Alternate Energy Sources

    Long queues for gasoline, high prices and shortage of gasoline are the signs which show that how natural resources are on the verge of depletion. This shows that it is high time for us to view how to utilize natural resources. India is mainly depended on import of petroleum products for its energy requirements. It meets its requirements by importing 70% of petroleum products. This is a point of ...

  • Energy and exergy analysis of R22 and its alternatives in a vapour compression refrigeration system

    In this paper, energy and exergy analyses and performance comparison of R22 and its alternatives, R407C and R410A, in a vapour compression refrigeration system (VCRS) have been presented. For this aim, detailed first law (energy) and second law (exergy) analysis of these three refrigerants have been performed. Analyses have been performed for different evaporator (range of -40°C to 0°C ...

  • The alternative to coal in South Africa

    With a desperate need for dispatchable generation, South Africa should be readily embracing CSP as a low-carbon, sustainable, base load energy alternative. So why do its energy authorities remain unconvinced? This question has formed the subject of Part 2 of the CSP Today South Africa Guide. London, UK October 11 2011 Forget green energy: while most nations are concerned ...

  • Sustainable alternative to the centralized paradigm

    The use of decentralized/distributed sewering is an emerging trend intended to bridge the gap between both central sewer and residential septic systems. Upgrading and improving a city’s wastewater-treatment infrastructure is one of the most important public policy issues and the most costly. Often not an environmental benefit, there is conclusive evidence that centralized sewer collection ...

  • Fuel alternatives for heavy equipment

    High fuel prices are leading composters and wood grinders to reevaluate diesel-guzzling heavy equipment, looking to alternatives that are both more cost-efficient and environmentally friendly. This could be as “simple” as filling up existing machines with biodiesel blends, could involve swapping out a diesel model for an electric one, or even go as far as generating electricity on site to power ...

    Executive Summary. Second Wind Inc. is pleased to offer a new standard anemometer for resource assessment that incorporates industry proven geometry and features. The new three-cup anemometer, the Second Wind Model C3, is physically similar to a popular anemometer designed by Maximum, Inc. and used in the wind industry for more than 30 years. However, the C3 employs more durable materials ...


  • Microalgae as a sustainable alternative for wastewater treatment

    Thanks to the threats posed to human health and the environment, and the economic costs of its treatment, wastewater from domestic, industrial and agricultural processes has been considered a serious problem for a long time. However, a paradigm shift in the past few years has led to a new concept of wastewater, not as a problem but as a source of energy and other precious resources, including ...

  • Alternative energy efficient membrane bioreactor using reciprocating submerged membrane

    A novel membrane bioreactor (MBR) pilot system, using membrane reciprocation instead of air scouring, was operated at constant high flux and daily fluctuating flux to demonstrate its application under peak and diurnal flow conditions. Low and stable transmembrane pressure was achieved at 40 l/m2/h (LMH) by use of repetitive membrane reciprocation. The results reveal that the inertial forces ...

  • Conventional and alternative water supply systems: a life cycle study

    Research on urban development to date has tended to focus on buildings and their performance in terms of associated energy and environmental impacts. Although, many detailed studies of residential buildings have been carried out, these studies usually concentrate on the house itself without consideration of the infrastructure systems. Alternatives to traditional infrastructure systems are ...
