Purpose of srp l.jpg
Purpose of SRP

PENNDOT’s Strategic Environmental Management (SEM) Program Office has developed a Strategic Recycling Program (SRP) as a tool to systematically identify, evaluate and implement recycling opportunities throughout the Commonwealth.


Background l.jpg
Background

PADEP and PENNDOT SRP Memorandum of Understanding (MOU) consist of:

  • Establishing and implementing a waste reduction program for materials used in PENNDOT operations;

  • Continually reviewing and revising existing procedures and specifications;

  • Evaluating materials that may be recycled in transportation and civil engineering applications;

  • Give due consideration and preference to projects that use compost materials in land maintenance activities;

  • Employs procurement and contract bidding options encouraging recycled materials use.

Strategic Recycling Program Five Key Focus

Research – To collect information on recycled materials, including the literature review process and the completion of laboratory, pilot and field scale studies, as warranted. The purpose is to identify and resolve data gaps associated with the use of recycled materials and to organize the supporting information for the development of recycled material specifications.

Specifications –To develop, obtain, and/or disseminate user guidelines, provisional special provisions and Publication 408 specifications at the Municipal, District and Statewide levels.

Projects – To identify, implement, evaluate, and monitor projects that use recycled materials. The overall objective is to successfully incorporate recycled materials in construction and maintenance projects, including post-construction monitoring phases.

Outreach –To communicate and disseminate the results and experiences of recycled materials projects to PENNDOT, Commonwealth agencies and the public using a variety of formats.

Contracting – To provide technical assistance to the Engineering Districts in developing and using purchase, service and/or construction contract mechanisms to specify or provide for recycled material use.

  • 2.f Sewage Sludge Compost. A blend of secondary dewatered sewage sludge and wood chips, aerobically composted at a Pennsylvania Department of Environmental Protection, Bureau of Waste Management permitted site for at least 21 days and cured for 30 to 60 days to ensure pathogen destruction. Free of foreign material and substances toxic to plant growth, nonburning, weed free, screened, and conforming to the following requirements:

    • Section (g) Soil Amendments

      • 3. Sewage Sludge Compost. A blend of composted sewage sludge and wood chips, conforming to the requirements specified in Section 805.2(a)2.f, except the maximum size particle is 10 mm (3/8 inch).

      • 4. Compost. Decomposed product derived from agricultural, food and yard organic matter source. Composted at a DEP, Bureau of Waste Management permitted site under industry standards and U.S. EPA regulations, to provide a stable, weed free, nontoxic, soil amendment with a non-objectionable odor, and conforming to the following requirements:


    Slide14 l.jpg

    808.2(g) 808.2(g)

    • moisture content—35 to 55%
