Environmental benefits of steel recycling
• Recycling steel saves energy and natural resources.
• In a year, the steel industry saves the equivalent energy to power about 18 million
households. When one ton of steel is recycled,
• 2500 pounds of iron ore,
• 1400 pounds of coal and
• 120 pounds of limestone are conserved.
• By making recycling integral to steelmaking, the steel industry leads the buy recycled
effort. Each year, more than 62% of the steel the domestic industry produces is
recycled.

9. Basic Oxygen Furnace
• The basic oxygen furnace (BOF) process uses 25 to
35 percent old steel to make new. It produces
products— such as automotive fenders,
encasements of refrigerators, and packaging like
soup cans, five-gallon pails, and 55-gallon drums—
whose major required characteristic is drawability.

10. BOF Rates
Therefore, the total recycled content to produce the
44,503,000 tons of raw steel in the BOF is: 14,552,500 / 44,503,000 = 32.7%
(Total Tons Ferrous Scrap / Total Tons Raw Steel)
Also, the post-consumer recycled content is:
(13,592,500 - 2,256,400) + 10,000 = 11,346,100
And 11,346,100 /44,503,000 = 25.5%
(Post-Consumer Scrap / Total Tons Raw Steel)
Finally, the pre-consumer recycled content is:
(760,000 + 2,256,400) / 44,503,000 = 3,016,400/ 44,503,000 = 6.8%
(Pre-Consumer Scrap / Total Tons Raw Steel)

11. Electric Arc Furnace
• The electric arc furnace (EAF) process uses more
than 80 percent old steel to make new. It produces
products— such as structural beams, steel plates,
and reinforcement bars—whose major required
characteristic is strength.

12. EAF Rates
Therefore, the total recycled content to produce the 61,329,700 tons of raw steel in
the EAF is: 57,199,300 / 61,329,700= 93.3%
(Total Tons Ferrous Scrap / Total Tons Raw Steel)
Also, the post-consumer recycled content is:
(41,710,600 - 6,924,000) + 85,000 = 34,871,600
And 34,871,600 / 61,329,700 = 56.9%
(Post-Consumer Scrap / Total Tons Raw Steel)
Finally, the pre-consumer recycled content is:
(12,323,000 +6,924,000) / 61,329,700 = 19,247,000 / 61,329,700 = 31.4%
(Pre-Consumer Scrap / Total Tons Raw Steel)

13. Sample Calculation
Steel Recycled Content Value =
(Value of Steel Product) (Post-Consumer % + ½ Pre-Consumer %)
BOF Steel Recycled Content Value for Typical Product: Culverts
Value = ($10,000) (25.5% + ½ 6.8%) = ($10,000) (28.9%) = $2,890
(Positive net contributor to 10% and 20% goals)
EAF Steel Recycled Content Value for Typical Product: Storm Drains
Value = ($10,000) (56.9% + ½ 31.4%) = ($10,000) (72.6%) = $7,260
(Positive net contributor to 10% and 20% goals)

15. LEED Credit Info
MR Credit 4: Recycled Content
1–2 Points
Intent
To increase demand for building products that incorporate
recycled content materials, thereby reducing impacts resulting
from extraction and processing of virgin materials.
© 2009 NCSPA

16. LEED Credit Info
Requirements
• Use materials with recycled content1 such that the sum of postconsumer2 recycled content plus 1/2 of
the pre-consumer 3 content constitutes at least 10% or 20%, based on cost, of the total value of the
materials in the project.
• The minimum percentage materials recycled for each point threshold is as follows:
• Recycled Content Points
• 10% - 1
• 20% - 2
• The recycled content value of a material assembly is determined by weight. The recycled fraction of the
assembly is then multiplied by the cost of assembly to determine the recycled content value.
• Mechanical, electrical and plumbing components and specialty items such as elevators cannot be
included in this calculation. Include only materials permanently installed in the project. Furniture may
be included if it is included consistently in MR Credit 3: Materials Reuse through MR Credit 7: Certified
Wood.

17. LEED Credit Info
Potential Technologies & Strategies
• Establish a project goal for recycled content materials, and identify material
suppliers that can achieve this goal.
• During construction, ensure that the specified recycled content materials are
installed. Consider a range of environmental, economic and performance attributes
when selecting products and materials.

18. LEED Credit Info
MR Credit 2: Construction Waste Management
1–2 Points
Intent
To divert construction and demolition debris from disposal in
landfills and incineration facilities. Redirect recyclable recovered
resources back to the manufacturing process and reusable
materials to appropriate sites.
© 2009 NCSPA

19. LEED Credit Info
MR Credit 3: Materials Reuse
1–2 Points
Intent
In addition, if demolition work is done on the job site – such as
removing old culvert -- up to two points that can be gained if the
weighted average values of steel and the other construction
materials meet the minimum values.

20. LEED Credit Info
MR Credit 5: Regional Materials
1–2 Points
Intent
To increase demand for building materials and products that are
extracted and manufactured within the region, thereby
supporting the use of indigenous resources and reducing the
environmental impacts resulting from transportation.

27. Summary
• Steel is North America's Number #1 Recycled Material. Each year, more steel is recycled than aluminum,
paper, glass and plastic combined!
• Scrap has become the steel industry's single largest source of raw material because it is economically
advantageous to recycle old steel into new steel. In light of this, steelmaking furnaces have been designed
to consume steel scrap.
• In fact, in the past 50 years, approximately 50 percent of the steel produced in this country has been
recycled through the steelmaking process. Thanks to the steel industry's impressive history of recycling, a
wide variety of collection programs exist to recycle steel products.
• All of these programs tap into the steel recycling infrastructure, a well-established network of more than
2,000 ferrous scrap processors and more than 70 end markets. This steel recycling infrastructure, which
has grown and matured over the years in its efforts to meet the steel industry's demand for steel scrap, is
the reason today's steel recycling efforts actually supersede those of the past.
