Reduce, Reuse, Recycle, Recover Energy
Materials Management dictates that we
look more closely at the materials we
use and then discard from both an
environmental and economically
sustainable point of view.
Materials Management Hierarchy
Recycling in the USA
150 million metric tons of scrap recycled annually. Of that:
• 85 million tons of iron and steel
• 5.5 million tons of aluminum
• 1.8 million tons of copper
• 2 million tons of stainless steel
• 1.2 million tons of lead
• 420,000 tons of zinc
• Lesser amounts of brass, bronze, magnesium and tin*

Importance of Recycling Metals
• Conserves resources
• Benefits the economy
– foreign and domestic
• Recycling saves energy
Did You Know?
Americans throw
away (dispose, not
recycle) enough
aluminum every
month to rebuild
our entire
commercial air
fleet.

Benefit: Conserves Resources
• Recycling one automobile conserves 2,500 pounds of
iron ore, 1,400 pounds of coal and 120 pounds of
limestone.
• Recycling a ton of aluminum conserves up to 8 tons of
bauxite ore.
• Steel is the most recycled material in the USA.

Benefit: Valuable Export Commodity
Benefit: Saves Energy
Recycling scrap metal reduces greenhouse gas emissions
and uses less energy than making metal from virgin ore.
The amount of energy saved using various recycled metals
compared to virgin ore is up to:
-- 92 % for aluminum
-- 90 % for copper
-- 56 % for steel
-- 65 % for zinc

Basic Metal Recycling Today
“Although the ultimate supply of
metal is fixed by nature, human
ingenuity determines the quantity of
supply available for use by
developing economic processes for
the recovery from the Earth (the
primary source of metal) and from
secondary sources (recycled from the
use/process stream). The reusable
nature of metals contributes to the
sustainability of their use.”

More Advanced Metals Recycling
• Concept: Consolidate ash processing from 3 small
facilities at one central location to recover additional Fe
and economically allow Non-Fe recovery
• Targeted Facilities: Springfield, Pittsfield and Wallingford
• Location: Bondi Island Landfill
– Locate the new facility on the Bondi Island Landfill
Footprint
Regional Metals Recycling
Pittsfield
Springfield & Bondi Landfill
Wallingford
Bondi Metals Recycling
• Benefits:
– Increases Fe recovery for Pittsfield and Springfield
– Allows Non-Fe to be recovered in greater quantities
– Semi-portable system may be moved as landfilling
operations progress
– Additional significant metals recycling in
Massachusetts

Covanta TARTECH,LLC
• New joint venture between Covanta Energy and German-based
TARTECH eco industries
• Primary purpose is to recover and recycle metals from ash monofills
• Uses TARTECH’s proprietary technology and conventional
equipment to recover metals from the ash
• Environmental benefits (metal recycling) while also recovers landfill
space
• Proprietary technology developed from a research project supported
by the German Federal Research Ministry (GFRM)
• Successful European operational experience
Metal Recycling: It’s Good for the
Environment and It’s Good for the
Economy
– Recovering metals increases recycling
– Provides jobs and revenue streams
– Reduces greenhouse gas (GHG) emissions
– More efficient use of earth’s resources
– Increases existing landfill life
