Is
Waste to Energy an option for Climate Change?
If
the goal is greenhouse gas reduction, then waste-to-energy is the option for
waste disposal. When greenhouse gases (GHG) such as methane, carbon
dioxide and nitrous oxide are released into the earth’s atmosphere, they trap
infrared radiation from sunlight. This is stored as heat in the
atmosphere and can be tied to the increase in the earth’s average temperature,
causing what is known as global warming or climate change. Waste to
Energy offsets greenhouse gases to combat climate change. According to
the U.S. Environmental Protection Agency (EPA), for every ton of municipal
solid waste processed at a Waste to Energy facility, the release of
approximately one ton of carbon dioxide equivalent emissions into the
atmosphere is prevented due to the avoidance of methane generation at
landfills, the offset of greenhouse gases from fossil fuel electrical
production, and the recovery of metals.
What
is green house gas and what are methane gases?
Methane
is a greenhouse gas, mostly emitted from decomposing waste in landfills, which
is 20 – 25 times the potency of carbon dioxide and is ranked as a dangerous
contributor to climate change. Waste to Energy facilities avoid the
production of methane while producing significantly more electricity from each
ton of waste compared to landfills. Further GHG reductions are realized by the
avoidance of carbon emissions from long-haul transportation methods used to
transport garbage to distant landfills. Waste used as fuel in WtE facilities is
typically generated in the surrounding area.
Is
waste to Energy recognized under the Kyoto protocol and the Clean Development
Mechanism program?
The
Kyoto Protocol is a United Nations international pact to reduce carbon dioxide
emissions. Under the Kyoto Protocol’s Clean Development Mechanism
program, waste to energy is recognized as a source of greenhouse gas credits.
The Okhla Waste to Energy facility has been registered under the UNFCC program.
