energy is a constantly available and reliable
fuel stream not derived from fossil fuels. It
is crucial in reducing America’s dependence
on foreign oil and is environmentally-friendly.
To date, 18 states and Washington D.C. have implemented
minimum renewable energy standards that require
utility companies to utilize energy sources, such
as wind, solar and bio energy. At E/S Alternatives, LP we recover two forms of renewable energy:
biomass and landfill gas to satisfy the growing
Each person in the United States generates
about 4.5 pounds of solid waste per day, about
one ton per year.
But landfill permits are timely,
as is decomposition. Waste deposited in municipal
solid waste landfills takes decades to decompose
producing a mixture of methane gas, CO 2 and other
gas traces. Since landfill gas is about 50 percent
methane it is both a potent greenhouse gas if
ignored and a valuable source of energy if employed
through gasification. Sorting and gasifying waste
streams extends the life of landfills and results
in green energy that can be employed by utility
Utilizing biomass recovery reduces landfill mass
and also extends the longevity of landfills. Biomaterials
such as woods and plants, agricultural wastes
and residues, and animal wastes are sorted and
shipped for gasification where the matter is heated
to 1500 degrees and broken down to release gases.
The gases are then turned into steam, which speeds
up the decomposition process while providing a
green energy source.
Replacing nonrenewable resources
such as coal, oil and gas with renewable energy
reduces the emissions of chemical compounds that
contribute to acid rain, global warming and respiratory
health concerns. R enewable energy recovery also
offers significant economic and energy benefits
that can be enjoyed by the landfill owner and
the entire community alike while reducing the
country’s dependence on foreign oil supplies.
