  • More recycling raises average energy content of waste used

     · Most municipal solid waste (MSW) used to generate electricity contains both biogenic and non-biogenic components. As consumers recycle or recover more biogenic waste (such as food waste and yard clippings) and discard more non-biogenic waste (such as plastics and metals), the biogenic portion of municipal solid waste decreases.

     · An average plant processing municipal solid waste can generate about kWh per ton at 6 cents per kWh, a ton of waste can bring in $30 to $36. Producing electricity through waste instead of fossil fuels also saves one barrel of oil or one quarter ton of coal for every ton of solid waste that is combusted.
