1Based
on 2007 EPA eGRID data except WTE which is a nationwide average using 34% anthropogenic CO2
2Life
Cycle CO2E for fossil fuels limited to indirect methane emissions using EPA GHG inventory and EIA power
generation data Life Cycle value would be larger if indirect CO2 was included
3Life
Cycle CO@E for WTE based on nominal nationwide avoidance ratio of 1 ton CO2E per ton of MSW using the
Municipal Solid Wastes Decision Support Tool, which included avoided methane and avoided CO2
Waste-to-Energy Reduces Greenhouse Gas Emissions in Three
Important Ways
Avoided methane emissions from landfills. When a ton of solid waste is
delivered to a waste-to-energy facility, the methane that would have been
generated if it were sent to a landfill is avoided. While some of this methane
could be collected and used to generate electricity, some would not be captured
and would be emitted to the atmosphere. Waste-to-energy generates more
electrical power per ton of municipal solid waste than any landfill gas-to-energy
facility.
Avoided CO2 emissions from fossil fuel combustion. When a megawatt of
electricity is generated by waste-to-energy facility, an increase in carbon dioxide
emissions that would have been generated by a fossil fuel fired power plant is
avoided.
Avoided CO2 emissions from metals production. Waste-to-energy plants
recover more than 700,000 tons of ferrous metals for recycling annually.
Recycling metals saves energy and avoids CO2 emissions that would have been
emitted if virgin materials were mined and new metals were manufactured, such
as steel.
THESE ARE ALL GOOD THINGS … … … … … … .
Major Strategy advantages:
• Convert balance of materials into energy, reduce mass
90 – 95%, only benign ash goes into the landfill
extending LF life by 9 times
Small footprint, 6 – 8 acres for up to 300 TPD plant, low
profile building reduces site line intrusion eliminating
landfilling of degradable material eliminates future
harmful GHG from methane emissions
• Smaller designs offer opportunity for smaller
communities unlike Incinerators and Plasma which
need large population to offset large capital
expenditure requirements
•
NO FOSSIL FUELS ARE USED BY OUR WASTE TO
ENERGY PLANTS, THEY PRODUCE THEIR OWN FUEL
•
Fossil fuel used for pile management is reduced 80 –
90% offering additional environmental & financial
benefit
•
Plastics cannot be infinitely recycled, they eventually
end up in landfills, low ash high energy is produced
from this waste.
•
A small Waste to Energy Plant can create 20+
permanent “Green Collar” jobs injecting $800k to
$1m in income revenue into the community.
Your Municipal Solid Waste should
not be WASTED

Convert solid waste into electricity and
decrease green house gases at the same time
5 Reasons
Waste to Energy Makes sense
• Every ton of Municipal Solid Waste (MSW)
converted to electricity saves 1 ton of CO2
• A Waste to Energy facility will recycle near
100% of all metal and glass.
• Savings of diesel fuel reduces the carbon
footprint and GHG emissions
• Extends landfill life, maybe indefinitely
• Creates the foundation for a green community
and environmental stewardship
