Recycling and Solid Waste Management Report
For Highway Construction, Maintenance Projects, and
Office Products

State Fiscal Year 2025

INTRODUCTION
This report is a summary of the recycling and solid waste management efforts on highway construction and maintenance projects within the North Carolina Department of Transportation (NCDOT) for State Fiscal Year (FY) 2025 (July 1, 2024 - June 30, 2025) as required by NC General Statute (G.S.) 136-28.8(g) and G.S. 130A-309.14(3). These
statutes mandate that the Department prepare an annual report on the amounts and
types of recycled materials specified or used in construction and maintenance projects
during the previous state fiscal year and review of bid procedures, respectively. The types of recycled materials incorporated into this report would routinely contribute to the consumer and industrial waste streams if not reused/recycled, compounding the problem of declining space in landfills, and resources.
Efforts to utilize recycled and solid waste materials are in response to the requirements of G.S 136-28.8(b) which mandates the Department use recycled materials in highway projects, where possible. All applications of recycled materials are to be consistent with
economic feasibility, applicable engineering, and environmental quality standards. In
addition, the Department continues to comply with Chapter 136 of the General Statutes
to encourage the purchase or use of reusable, refillable, repairable, more durable, and less toxic supplies, and products. In addition to recycled/recyclable materials from Department construction and
maintenance activities, this report also contains information regarding common recyclable items such as glass, plastics, aluminum cans, office paper, etc. that were previously reported separately. Requirements for the submission of this office and rest area data are required by G.S. 130A-309.07 through 309.14, G.S. 143-58.2(f), and
Executive Order 156.
BID PROCEDURE REVIEW
The Department continues to review bidding procedures and processes yearly to encourage the purchase and use of recycled and reusable products and practices in construction and maintenance projects. Section 104-13 of the NCDOT Standard Specifications for Roads and Structures encourages Contractors to not only use
recycled or solid waste materials in their projects but also allows them the opportunity to initiate and develop the use of recycled products and construction methods that promote sustainability. Furthermore, the contractor is required to report the use of recycled materials by July 1st each year.
DATA COLLECTION
All offices submitted data for this report via an online webform. The online webform is separated into two sections, one for the “construction and maintenance” data, and one for “DOT/DMV Offices and Rest Areas” data (formerly the “3R Report”). The totality of data included in this report comes from three separate sources:

1. HiCAMS (Highway Construction and Materials System) database, 2. Various NCDOT Offices (entered in a SharePoint form), and 3. NCDOT Roadside Environmental Unit’s Litter Cleanup Programs The data reported in Table 1 from HiCAMS is denoted by an asterisk (*). HiCAMS is
NCDOT’s main repository of project and material level information. The HiCAMS information, however, is not conclusive, as many county maintenance project materials are not included. NCDOT Standard Specification Section 104-13 states that contractors are to report the quantities of reused or recycled materials for each contract and any
practice that minimized the environmental impacts by July 1st each year, but the
reporting response rate remains low. The data reported in Table 1 are all rounded down to the nearest whole number for
each item. Several important points regarding data collection need to be made for
clarification and consistency purposes:
1. Reclaimed Asphalt Pavement (RAP) quantities and Reclaimed Asphalt Shingles (RAS) quantities are being reported as one item. This is necessary since changes were made to NCDOT’s HiCAMS database that now require the combined reporting of these two constituents.
2. The glass beads (Section 5) contained in pavement markings can come from recycled sources, however the exact percentage and quantity is not completely known. Therefore, the entire quantity of glass beads is currently listed as a recycled/recyclable product.
3. The Plastics section (Section 6) includes products that contain recycled
components and products that could be recycled in the future. The plastic pipe
component is composed of all dimensions and compositions of plastic pipe. The exact amount of recycled plastic and recyclable plastic cannot be determined given the limited amount of data present. Therefore, all plastic pipe types and sizes were combined in a single category.
4. The Metals section (Section 8) is presumed to be composed of steel. However, various grades and types of steels are included, and our office cannot verify that this section does not include other metals such as Aluminum. Furthermore, the materials listed do not specify a recycled content amount. The materials are
included as a product that will be, or could be recycled in the future, and one that
contains an unknown quantity of recycled metals presently. It is therefore
included as both a recyclable product and a recycled product. 5. Scrap metal is listed as one line item in Section 8; some of the scraps are presumed to be recycled guardrail, sheet piles, and pipes, but their individual quantities cannot be determined at this time.

(*) Data pulled from HiCAMS as of 9/22/2025 (^) Data pulled from HiCAMS and combined with data reported by NCDOT field offices on 9/22/25 The data reported in Table 2 are all rounded down to the nearest whole number for each
item. Several offices and rest areas report their recycling report data as commingled
recycling. As such, it is not possible to determine the quantities of each constituent
material, and therefore a “commingled” product line is listed in Table 2.

The total weight of office and rest area recycling is 315,596 pounds. This total does not
include items for which the unit of measure for a recycled item was listed as each or
gallon. Table 3 contains the reported recycling data from the NCDOT Roadside Environmental Unit’s various litter cleanup programs.
