Product Information:

Database of Manufacturers and Suppliers
This database identifies manufacturers and suppliers of designated products containing recovered materials.

GSA Advantage!
The U.S. General Services Administration (GSA) has an online ordering system and publishes various supply catalogs, guides, and schedules for recycled-content products through the Federal Supply Service.

GSA has a Green Products Sustainable Facilities Tool to help federal procurement agents identify products, their environmental attributes, and where to buy them.

This fact sheet highlights the transportation products designated in the CPG, including traffic control devices, and includes case studies, recommended recovered-content levels, and a list of resources. 

Channelizers, Delineators, and Flexible Delineators

Channelizers: Channelizers are barrels or drums that direct traffic around areas of road repair or construction. Channelizers are designed and colored to be highly visible and can be constructed from recovered HDPE and rubber. The bases of the drums are weighted to provide stability and are often made from used tires.

Delineators: Delineators are temporary pavement markers that come in many shapes, sizes, and designs. They are manufactured primarily from recovered and postconsumer HDPE. Delineator bases are either steel stakes that can be driven into the ground or rubber to support the delineator on the road surface.

Flexible Delineators: These products come in the form of stakes and are driven into the ground. The product is flexible enough so that vehicles can strike them without causing damage to the vehicle or delineator. They are used at golf courses, airports, military bases, shopping centers, and recreation areas.
EPA's designation specifically covers channelizers, delineators, and flexible delineators containing recovered plastic, rubber, or steel.

Recommended Recovered Materials Content Ranges:

EPA's Recovered Materials Advisory Notice (RMAN) recommends recycled-content levels for purchasing channelizers, delineators, and flexible delineators as shown in the table below.

EPA's Recommended Recovered Materials Content Levels for Channelizers, Delineators, and Flexible Delineators Containing Recovered Plastic, Rubber, or Steel 
Product Material Postconsumer Content Total Recovered Materials Content (%)
Channelizers Plastic 25-95 25-95
Rubber ² (base only)) 100 100
Delineators Plastic 25-95 25-95
Rubber (base only) 100 100
Steel ³ (base only) 16
67
25-30
100
Flexible Delineators Plastic 25-85 25-85


╣The recommended recovered materials content levels are based on the weight (not volume) of materials in the insulating core only.

▓Content levels are based on the dry weight of the raw materials, exclusive of any additives such as adhesives, binders, or coloring agents.

│The recommended recovered materials content levels for steel in this table reflect the fact that the designated items can be made from steel manufactured in either a Basic Oxygen Furnace (BOF) or an Electric Arc Furnace (EAF). Steel from the BOF process contains 25-30 percent total recovered materials, of which 16 percent is postconsumer steel. Steel from the EAF process contains a total of 100 percent recovered steel, of which 67 percent is postconsumer.

Product Specifications:

EPA recommends that procuring agencies use the following specifications when procuring channelizers, delineators, and flexible delineators:

Parking Stops

Commonly found in parking lots, parking stops are used to mark spaces and keep vehicles from rolling beyond a designated parking area. EPA's designation specifically covers parking stops made from concrete or containing recovered plastic or rubber.

Recommended Recovered Materials Content Ranges:

EPA's RMAN recommends recycled-content levels for purchasing parking stops as shown in the table below.

EPA's Recommended Recovered Materials Content Levels for Parking Stops Made from Concrete or Containing Recovered Plastic or Rubber
Product Material Postconsumer Content (%) Total Recovered Materials Content (%)
Parking Stops Plastic and/or Rubber ² 100 --
Concrete Containing Coal Fly Ash -- 20-40 ³
Concrete Containing Ground Granulated Blast Furnace Slag (GGBF) -- 25-70


╣Transportation products containing recovered materials must conform to the Manual on Uniform Highway Traffic Control Devices used by the Federal Highway Administration, as well as other applicable federal requirements and specifications.

²Parking stops made with recovered plastics may also include other recovered materials such as sawdust, wood, or fiberglass. The percentage of these materials contained in the product would also count toward the recovered materials content level of the parking stops.

³Generally, 20 to 30 percent, but could be up to 40 percent. Fifteen percent when used as a partial cement replacement as an admixture in concrete.

Product Specifications:

American Society for Testing and Materials (ASTM) specification C595M-13 Exit EPA Standard Specification for Blended Hydraulic Cements specifies the appropriate mix design, including recovered materials content, for concrete containing coal fly ash and GGBF slag.

Traffic Barricades

Traffic barricades can be used to redirect or restrict traffic in areas of highway construction or repair. They are typically made from wood, steel, plastic, fiberglass, or a combination of these materials. Many manufacturers have switched to the use of recycled materials in both the supporting frame and rails of the barricades. EPA's designation covers only Types I and II traffic barricades.

Recommended Recovered Materials Content Ranges:

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

EPA's Recommended Recovered Materials Content Levels for Traffic Barricades (Types I and II) ╣
Product Material Postconsumer Content (%) Total Recovered Materials Content (%)
Traffic Barricades Plastic 
(HDPE, LDPE, PET)
80-100 100
Steel 16
67
25-30
100
Fiberglass -- 100


╣The recommended materials content levels for steel in this table reflect the fact that the designated items can be made from steel manufactured in either a Basic Oxygen Furnace (BOF) or an Electric Arc Furnace (EAF). Steel from the BDF process contains 25-30 percent total recovered materials, of which 16 percent is postconsumer steel. Steel from the EAF process contains a total of 100 percent recovered steel, of which 67 percent is postconsumer.

Traffic Cones

Traffic cones are used to mark a road hazard or to direct traffic. Recovered plastics are used in the upper component of the cones, and crumb rubber and/or plastics are used in the base.

Recommended Recovered Materials Content Ranges:

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

EPA's Recommended Recovered Materials Content Levels for Traffic Cones 1,2
Product Material Postconsumer Content (%) Total Recovered Materials Content (%)²
Traffic Cones Plastic (PVC and LDPE) -- 50-100
Crumb rubber -- 50-100
