Developing Uses of Recycled Roofing Shingle Products for Non-Roofing Applications


GAF is a leading supplier of building materials with leading product offerings for both residential and commercial roofing segments. Headquartered in Parsippany, NJ, GAF has twenty-seven manufacturing operations in the US and four R&D locations. A majority (>75%) of the US residential roofs are asphalt shingle based. GAF estimates approximately thirteen million tons of waste is generated each year as a result of roof replacement due to end of life or special event causes such as hail. Less than ten percent of this waste is actually diverted from the landfill. GAF wants to solve this fundamental issue for a major roofing product.

GAF has developed a proprietary process to recycle asphalt shingles into two product streams. One stream can be used within GAF to make new asphalt shingles and the other stream produces recycled asphalt shingle (RAS) briquettes that can be partially used to make new asphaltic shingles. GAF is exploring alternative non-roofing applications for usage of the RAS briquettes. GAF has shortlisted four key areas of alternative use for the team to assess. The team will also explore applications beyond these four identified areas.

Purdue University Organic Waste Diversion Study


Purdue University’s 2020 Physical Facilities Sustainability Master Plan established goal M-1 to achieve an annual campus waste recycling (diversion) rate of 50% by FY25, aligning with the state of Indiana’s goal (IC 13-20-25-1) to recycle at least fifty percent of its municipal waste. Indiana Department of Environmental Management’s (IDEM) 2021 Recycling Index Report identified organic waste diversion as a key impact area in reaching the states goal of 50% recycling. Across the state, as well as nationally, there is a lack of adequate infrastructure to correctly divert organic waste.

A study is needed to understand current and future flow of these materials on campus, determine the feasibility of diversion methods, and inform procurement and operations planning. Purdue University Campus Planning, Architecture and Sustainability is requesting the team provide deliverables for mapping the movement of and evaluating the quality of the organic waste stream materials. They should also quantify costs of the current system and evaluate current diversions methods at campus, locally, and regionally.

Purdue University Transfer Station Relocation Impact Study


Purdue University’s 2020 Physical Facilities Sustainability Master Plan established goal M-1 to achieve an annual campus waste recycling (diversion) rate of 50% by FY25, aligning with the state of Indiana’s goal (IC 13-20-25-1) to recycle at least fifty percent of its municipal waste. The operational success of this goal is largely dependent on a regional system of public and private organizations who haul, handle and process Purdue University’s municipal solid waste (MSW). An integral part of the local regional system is the Tippecanoe County transfer station, where Purdue currently hauls the majority of its MSW. A plan was released in January 2023 proposing the transfer station relocates notably farther away from campus.

Purdue University Campus Planning, Architecture and Sustainability along with Purdue Grounds is requesting a study to evaluate the significance of the transfer station’s move on Purdue’s operations and to determine the feasibility of measures needed to mitigate any negative effects. There is interest in finding a solution which reduces the operational strain, while also enhancing the economics and increasing the diversion rate.

Worthington Lagoon Wastewater Treatment Plant Improvements


Wessler Engineering is a civil and environmental engineering firm based in Indianapolis that specializes in wastewater, drinking water and stormwater projects. The Town of Worthington owns a lagoon-style wastewater treatment plant (WWTP), consisting of influent flow metering, two (2) 4.25 MG aerated lagoon cells operated in series, chlorine gas disinfection and sulfur dioxide dechlorination, and effluent flow metering.

Over recent years, the Indiana Department of Environmental Management (IDEM) has made effluent pollutant limits for WWTPs more stringent to protect stream quality. Lagoon microbiology often struggles to adequately treat ammonia in certain climates and over the past several years, the Worthington WWTP has struggled to meet its permitted effluent ammonia limit. In addition, the chlorine gas disinfection system has reached the end of its useful life and poses safety risks to operators. The objective of this project is to evaluate the existing Worthington WWTP and determine a feasible, reliable, and cost-effective solution to meet the current and future wastewater needs of the community.
