Turning Trash into Electricity

Florida county plans to vaporize landfill trash:

The $425 million facility expected to be built in St. Lucie County will use lightning-like plasma arcs to turn trash into gas and rock-like material. It will be the first such plant in the nation operating on such a massive scale and the largest in the world.

Supporters say the process is cleaner than traditional trash incineration, though skeptics question whether the technology can meet the lofty expectations.

The 100,000-square-foot plant, slated to be operational in two years, is expected to vaporize 3,000 tons of garbage a day. County officials estimate their entire landfill — 4.3 million tons of trash collected since 1978 — will be gone in 18 years.

No byproduct will go unused, according to Geoplasma, the Atlanta-based company building and paying for the plant.

Synthetic, combustible gas produced in the process will be used to run turbines to create about 120 megawatts of electricity that will be sold back to the grid. The facility will operate on about a third of the power it generates, free from outside electricity.

    Have any public hearings been held on this trash to electricity proposal? What is the tax payer liability on this project? Where has this technology been proven?

    “The initial voltage is about equal to the zap from a police stun gun. But once the cycle is under way, the 2,200˚F syngas is fed into a cooling system, generating steam that drives turbines to produce electricity…”

    Teams that deal regularly with SMEs (that_s Small and Medium sized Enterprises,
    to you and me) are better equipped to understand the needs of the sector.
    It also provides a guide to how organisations can cut their energy consumption, and therefore carbon footprint and annual energy costs, throughout the organisation and over the lifecycle of IT equipment, from the desktop and office
    consumables to the data center and the recycling of
    electronic equipment. It has to be physically raped and the careful relic necessary to be unfrozen.
