  • How toxic is coal ash? A laboratory toxicity case study

    Under a consent agreement among EPA and proponents both for and against stricter regulation, EPA is to issue a new coal ash disposal rule by the end of 2014. Laboratory toxicity investigations often yield conservative estimates of toxicity since many standard test species are more sensitive than resident species, thus could provide information useful to the rule‐making. However, few laboratory ...

  • Coal-fired power on the way out?

    The past two years have witnessed the emergence of a powerful movement opposing the construction of new coal-fired power plants in the United States. Initially led by environmental groups, both national and local, it has since been joined by prominent national political leaders and many state governors. The principal reason for opposing coal plants is that they are changing the earth’s climate. ...

  • Electrofilter protection by fast monitoring of CO in flue gas – Case Study

    Electrostatic precipitators Many industrial operations produce exhaust gases that contain dust, fly ash (unburned constituents), fumes (including fine elemental particles such as cadmium, sulfur and lead) and mist (such as coal tar), which cause an unwanted impact to human health and the environment. One widely used method of removing such contaminants from a gas stream is to use an ...

  • Why is Energy-from-Waste slow to catch on in the U.S.?

    Nithin Coca reports in TriplePundit that Energy-from-Waste (EfW) is growing fast in Europe and parts of Asia. But it’s relatively stagnant here in the United States. In fact, the percentage of waste we burn for energy is actually slightly down in the past five years. What’s holding the U.S. back from this potentially sustainable solution? This stagnation is even more ...
