##  Implementing E.O. 13423: Opportunities for Industrial Materials Recycling

- Federal Environmental SymposiumJune 4, 2007
- Nicole Villamizar
- U.S. EPA, Office of Solid Waste

## Overview 

- What are industrial materials, and why should they be recycled?
- What is EPA’s Industrial Materials Recycling (IMR) Program?
- How can IMR help federal agencies comply E.O. 13423?
- Case Studies & additional resources
- Summary points

## What are industrial materials, and why should they be recycled?

- Industrial materials are the byproducts of industrial processes
- Examples: Coal ash, slag, silica fume, spent foundry sand, and construction and demolition (C&D) materials
- U.S. produces over half a billion tons annually
- Industrial materials have chemical and physical properties similar to virgin materials

## What are industrial materials, and why should they be recycled?

- Environmental and economic benefits:
- Preserves natural resources
- Saves energy and reduces GHG emissions
- Reduces disposal costs for generators & material cost for end users
- Keeps valuable materials out of landfills
- Performance benefits:
- Coal ash (in replacement of cement) can improve the strength and durability of concrete
- For buildings, earns LEED credits

## What is EPA’s Industrial Materials Recycling (IMR) Program?

- Increasing the recycling and beneficial use of industrial materials is a priority of EPA’s Resource Conservation Challenge (RCC)
- The IMR Program was formed to develop and implement strategies to achieve the RCC goals for industrial materials recycling

## What is EPA’s IMR Program? (cont’d...) 

- EPA is currently focusing on 3 industrial material streams:
- Coal combustion products
-  C&D materials
- Spent foundry sand

## What is EPA’s IMR Program? (cont’d...)

| Material | Can be recycled in: |
| --- | --- |
| Coal Combustion Products | -Portland cement and concrete
-Flowable and structural fill
-Agricultural uses |
| C&D materials | -Asphalt paving 
-Concrete
-Re-milled lumber |
| Foundry sand | -Road embankments
-Agricultural uses |

## What is EPA’s IMR Program?(cont’d...) 

- Why focus on these three material streams?
- Existing markets
- Large volumes
- Improvable recycling rates
- IMR Program focus may expand to include other industrial materials
- (e.g., slag, scrap tires, silica fume, pulp from paper mills.)

## What is EPA’s IMR Program?(cont’d...) 

- Initiatives include:
- Coal Combustion Products Partnership (C2P2)
- Recycling C&D materials
- Recycling spent foundry sand
- Construction Initiative

How can industrial materials 
recycling help your agency comply 
with E.O. 13423?

(Why you are here)

- How can industrial materials
- recycling help your agency comply
- with E.O. 13423?
- (Why you are here)

## Part (V) of this MOU: Reduce environmental impact of materials
Purchase products with recycled content 
Salvage or recycle 50% of C&D materials  

- Purchase products with recycled content
- Salvage or recycle 50% of C&D materials

**Sec. 2 (f) of the E.O.: ***“Ensure that new construction and major renovation of agency buildings comply with the Federal Leadership in High Performance and Sustainable Buildings MOU (2006)”*

## “Recycled Content: For EPA-designated products, use products meeting or exceeding EPA’s recycled content recommendations...”
			-Part V of the Federal Leadership in 				High Performance and Sustainable 				Buildings MOU

- 			-*Part V of the Federal Leadership in **	**	**	**	**High Performance and Sustainable **	**	**	**	**Buildings MOU*

## How can industrial materials recycling help your agency comply with E.O. 13423?

- EPA recommends the use of coal fly ash, ground-granulated-blast-furnace-slag (GGBF), cenospheres, or silica fume in cement and concrete products

***Recycled-content construction products***

## Why use construction products containing recycled industrial materials?

- Improves the strength and durability of concrete and bricks
- Earns LEED points in the materials and resources category
- Reduces the environmental impact of construction

## “Construction Waste: During a project’s planning stage, identify local recycling and salvage operations that could process site-related waste.  Program the design to recycle or salvage at least 50 percent of construction, demolition and land-clearing waste...”

## How can industrial materials recycling help your agency comply with E.O. 13423?

- EPA’s IMR program can:
- Help you identify local C&D recyclers
- Provide you with case studies and model contract language
- Assist in waste reduction opportunities

***C&D waste diversion and recycling***

## 
So, is anybody else doing it? 

(Yes!)

**So, is anybody else doing it? **
**(Yes!)**

## Case Study 1

- 70%+ construction materials recycled
- Soil, concrete reused for site grading
- 60% of materials used (by cost) were sourced or manufactured locally

***Jones Federal Building and Courthouse***

## Case Study 2

- LEED Gold certified
- 70%+ construction waste recycled
- 27% of the materials contained recycled content
- 63% of the materials were manufactured regionally

- Arlington, VA

***EPA Potomac Yards Building***

## Case Study 3

- Largest building in Washington, DC
- Concrete contains 25% coal fly ash
- Recycled content: steel, aluminum, gypsum wallboard

***Ronald Reagan Building & International Trade Center***

## Summary Points

- Industrial materials can help your agency comply with EO 13423
- Recycled-content *construction* products
- C&D waste diversion and recycling
- Earns LEED credits (materials & resources)
- EPA’s IMR Program staff can offer agencies technical assistance & connect you with experts in the field
- Industrial Resources Council (Coal ash, slag, foundry sand, scrap tire, C&D recycling industries)
