  • Boiler project at treatment plant paying dividends

    Communication, Environmental Design


    APPLETON — A new boiler system installed in 2011 at Appleton’s wastewater treatment plant is paying dividends for taxpayers, yielding $300,000 in energy savings annually.

    The $1.2 million methane system captures the byproduct of the bacterial breakdown of sludge to operate the boiler and heat the rest of the plant. The plant’s natural gas bill — which previously averaged $453,511 a year — dropped to $140,938 in 2012 and the savings are expected to continue annually.

    “Overall our billings for natural gas have been reduced by two-thirds,” said Chris Shaw, Appleton’s utilities director. “It was a good project and the payback is less than four years. It’s a very good deal for Appleton residents.” The methane boiler system heats the 38-acre facility’s 19 buildings and tunnel system. On very cold winter nights, the plant relies on the old natural gas system to supplement the methane boilers. While natural gas has an energy value of 1,000 Btu per cubic foot, methane produces about 650 Btu, Shaw said.

    The wastewater treatment plant has two giant egg-shaped digesters. The tan Teflon and fiberglass tanks — which are easily recognizable along the Fox River — each hold 2.2 million gallons of sludge that go through an anaerobic bacterial breakdown.

    “They both have to be heated up to 95 degrees so regardless of time of year, we’re constantly heating those vessels and the material,” Shaw said. “In the winter we’re fortunate to have some residual gas to heat t...


    The Commission by environmental campaigners forecast 3 trillion euros would generate by 2050 on their green revolution campaign- to make EU energy almost totally carbon free.

    The energy shift would already create around half a million extra jobs by 2020, Crown researchers from German aerospace center DLR, which also specializes in energy and transport, found. It has legislated to ensure that 20 percent of the energy mix is green by the said year, as part of a set of three main environmental goals. But it has yet to achieve agreement on binding targets beyond 2020, even though non-binding roadmaps have laid out the need for a virtually carbon-free electricity mix by 2050.

    Commissioned by Greenpeace and the European Renewable Energy Council (EREC), the 2012 Energy evolution report lays out risk avoidance towards almost carbon-free energy. They include curbing energy demand through greater efficiency, increasing investment in wind and solar power and phasing out subsidies for carbon-intensive energy, such as coal.

    To bring about the energy transformation, it sees a need to invest about 99 billion euros between now and 2050 or else this will be added on the list of renewable energy scam, but it says the financial gains are much greater. Renewable energy has no fuel costs; the fuel cost savings in the energy evolution scenario reach a total of 3, 010 billion euros up to 2050, or 75 billion per ...
