¹EPA recommends that, based on the recovered materials content levels shown in the table above, procuring agencies establish minimum content standards for use in purchasing polyester carpet for moderate-wear applications. This recommendation does not include polyester carpet for use in heavy-wear or severe-wear applications.

Product Specifications:

Procuring agencies should also refer to GSA's minimum density recommendations, as follows:

While numerous carpet specifications exist, the members of the carpet industry do not utilize any universal standards. Specifications vary and are determined based on the particular factors of the installation. The project's designer, architect, general contractor, and/or facility manager typically decide the specifications. Some procuring agencies, such as the Department of the Army and the Department of Housing and Urban Development, have developed their own specifications for end-use carpet applications. These specifications should be readily available to procurement officials in those agencies.

Cement and concrete

Coal fly ash, ground granulated blast furnace (GGBF) slag, cenospheres, and silica fumes are recovered materials that are readily available in some areas for use as ingredients in cement or concrete. Coal fly ash is a byproduct of coal burning at electric utility plants. Slag is a byproduct of iron blast furnaces. The slag is ground into granules finer than Portland cement and can be used as an ingredient in concrete. Cenospheres are small, inert, lightweight, hollow, glass spheres that are a component of coal fly ash. They can be added to cement to produce a specialty, high performance concrete. Silica fume is a waste material recovered from alloyed metal production. It can also be added to cement to produce a high performance concrete.

Recommended Recovered Materials Content Ranges:

EPA recommends that procuring agencies prepare or revise their procurement programs for cement and concrete or for construction projects involving cement and concrete to allow the use of coal fly ash, ground granulated blast furnace slag (GGBF slag), cenospheres, or silica fume, as appropriate. EPA does not recommend that procuring agencies favor one recovered material over the other. Rather, EPA recommends that procuring agencies consider the use of all of these recovered materials and choose the one (or the mixture of them) that meets their performance requirements, consistent with availability and price considerations. EPA also recommends that procuring agencies specifically include provisions in all construction contracts to allow for the use, as optional or alternate materials, of cement or concrete which contains coal fly ash, GGBF slag, cenospheres, or silica fume, where appropriate. Due to variations in cement, strength requirements, costs, and construction practices, EPA is not recommending recovered materials content levels for cement or concrete containing coal fly ash, GGBF slag, cenospheres, or silica fume. However, EPA is providing the following information about recovered materials content.

Product Specifications:

Consolidated and reprocessed latex paint for specified uses

Reprocessed paint is postconsumer latex paint that has been sorted by a variety of characteristics including type (i.e., interior or exterior), light and dark colors, and finish (e.g., high-gloss or flat). Reprocessed paint is available in various colors and is suitable for both interior and exterior applications. Consolidated paint consists of postconsumer latex paint with similar characteristics (e.g., type, color family, and finish) that is consolidated at the point of collection. Consolidated paint is typically used for exterior applications or as an undercoat.

Recommended Recovered Materials Content Ranges:

EPA's Recovered Materials Advisory Notice (RMAN) recommends recycled-content levels for purchasing reprocessed and consolidated latex paint for specified uses as shown in the table below.

EPA's Recommended Recovered Materials Content Levels for Reprocessed and Consolidated Latex Paints ¹
Product Postconsumer Content (%) Total Recovered Materials Content (%)
Reprocessed Latex Paint:
- White, Off-White, Pastel Colors 20 20
- Grey, Brown, Earthtones, and Other Dark Colors 50-99 50-99
Consolidated Latex Paint 100 100

1EPA's recommendation does not preclude agencies from purchasing paints manufactured from other, non-latex materials, such as oil-based paints. It simply recommends that procuring agencies, when purchasing latex paints, purchase these items made from postconsumer recovered materials when these items meet applicable specifications and performance requirements.

Product Specifications:

EPA recommends that procuring agencies refer to GSA commercial item description (CID) A-A-3185 when purchasing recycled paint. Currently, the CID is not available electronically.

For more information on EPA's product research on recovered-content latex paint, please see the Technical Background Document for RMAN II.

Floor tiles

Floor tiles for heavy duty or commercial specialty applications can contain up to 100 percent postconsumer rubber. They are made from used truck and airline tires.

Recommended Recovered Materials Content Ranges:

Flowable fill

Flowable fill is commonly used as an economical fill or backfill in road construction. It is usually a mixture of coal fly ash, water, a coarse aggregate (such as sand), and portland cement. Flowable fill can take the place of concrete, compacted soils, or sand commonly used to fill around pipes or void areas. Other applications include filling in bridge abutments, foundation subbases, or abandoned man holes and wells. Flowable fill can help put significant quantities of coal fly ash and spent foundry sand, two types of recovered materials, back to good use.

Recommended Recovered Materials Content Ranges:

EPA recommends that procuring agencies use flowable fill containing coal fly ash and/or ferrous foundry sands for backfill and other fill applications. Specific content levels will depend on the specifics of the job, including the type of coal fly ash (Class C or Class F) or foundry sand used, strength, set time, flowability needed, bleeding, and shrinkage. See a table showing typical proportions for high and low coal fly ash content mixtures.

Modular threshold ramps

Threshold ramps are used to modify door thresholds and other small rises to remove barriers that changes in level landing create, particularly with regards to access by people with disabilities. Modular threshold ramps are typically used for retrofitting buildings to comply with the Architectural Barriers Act (ABA) of 1968, the Rehabilitation Act of 1973, the Uniform Federal Accessibility Standards (UFAS) and the Americans with Disabilities Act (ADA) of 1990. Modular threshold ramps made from rubber, aluminum, and steel can be made from recovered materials.

Recommended Recovered Materials Content Ranges:

EPA's Recovered Materials Advisory Notice (RMAN) recommends recycled-content levels for purchasing modular threshold ramps as shown in the table below.

EPA's Recommended Recovered Materials Content Levels for Modular Threshold Ramps
Product Material Postconsumer Content (%) Total Recovered Materials Content (%)
Modular Threshold Ramps Steel 1 16-67 25-100
Aluminum -- 10
Rubber 100 100

¹The recommended recovered materials content levels for steel in this table reflect the fact that the designated item may contain steel manufactured in either a Basic Oxygen Furnace (BOF) or an Electric Arc Furnace (EAF), or a combination of both. Steel from the BOF process contains 25-30 percent total recovered steel, of which 16 percent is postconsumer. Steel from the EAF process contains 100 percent total recovered steel, of which 67 percent is postconsumer. According to industry sources, modular threshold ramps containing a combination of BOF and EAF steel would contain 25-85 percent total recovered steel, of which 16-67 percent would be postconsumer. Since there is no way of knowing which type of steel was used in the manufacture of the item, the postconsumer and total recovered material content ranges in this table encompass the whole range of possibilities, i.e., the use of EAF steel only, BOF steel only, or a combination of the two. These recommendations are for modular threshold ramps. EPA understands that ramps may also be constructed of cement and concrete. For these ramps, procuring agencies should follow the procurement guidelines for cement and concrete containing recovered materials.

Product Specifications:

Although the federal government is not governed by ADA, the Access Board's ADA standards are more current than the UFAS and are therefore generally used by federal facilities. According to the "Americans with Disabilities Act Accessibility Guidelines for Buildings and Facilities" (28 CFR Part 36), published in the Federal Register, July 26, 1991, ground and floor surfaces along accessible routes and in accessible rooms and spaces including floors, walks, ramps, stairs, and curb ramps, must be stable, firm, and slip-resistant. The guidelines do not define what is meant by "stable, firm, and slip-resistant," but the Access Board recommends static coefficient of friction values of 0.8 for ramps and 0.6 for accessible routes.

Although the federal government is not governed by the Department of Justice Americans with Disabilities Act (ADA) , the ADA Access Board’s standards are useful.
