Dr. Wang is leading a research team to conduct a research project titled " Using Recycled Concrete Aggregate in Non-Structural Concrete on NCDOT Projects in Eastern NC". This $185,000 grant is awarded by the North Carolina Department of Transportation (NCDOT) for the period of 2016-2018. The research project will study the use of recycled concrete aggregate (RCA) in non-structural concrete in NCDOT projects in eastern NC from both technical and cost aspects. The coarse RCA will undergo a series of conventional and special laboratory testing and used in concrete mixing. Engineering and cost analyses will be performed based on the data collected from the survey, testing, and literature review. Guidelines for RCA users, the procedures for processing and selecting RCA, and a new specification for the use of RCA in Class B concrete will be developed. It is anticipated that the research results and products will assist NCDOT in developing alternative concrete aggregates and provide contractors the opportunity to use RCA in NCDOT's projects. The results will benefit the bridge and road construction projects specified in the STIP for 2016-2025. The sustainable development in eastern North Carolina - one of the fastest growing regions in the State of North Carolina is also supported by the comprehensive use of recycled concrete aggregate supporting the conservation of natural resources and balancing economic, environmental, and societal needs.

The research team includes Dr. Donna Hollar, Dr. Kamalesh Panthi; Graduate Assistants Mr. Siddharth Patel, Mr. Jamel Pittman, and Lab Supervisor, Mr. Andrew Wilson.

Greening Coastal Vacation Rental Properties (EPA, Source Reduction Program 2012-2015)

PI: Dr. Tarek Abdel-Salam

 

In this project 31 environmental site audits of vacation rental homes were conducted in the vacation rental dense communities of North Carolina’s Outer Banks and provide individual written reports outlining cost effective pollution prevention and green building recommendations based on the assessment of the rental property. Information on the specific needs of coastal vacation rental properties were collected to improve the NC GreenTravel recognition criteria for vacation rentals. Resources specific to improving the energy efficiency and environmental performance of vacation rentals were created. Property owners and vacation rental property management businesses were offered relevant and applicable information to improve the environmental performance of their properties.

 

Lean and Green at North Carolina Wineries and Breweries: Putting Theory into Practice. (EPA, Pollution Prevention Program, 2014-2017) 

PI: Dr. Tarek Abdel-Salam

The project translates Lean and Green principles to production practices by providing on-site pollution prevention technical assistance for the craft brewing and small to medium winery industry of North Carolina, both growing industries in the state. This effort serves to reduce pounds of pollution, conserve water and/or energy, reduce greenhouse gases, and save money through economy, energy, and environment (E3).

 

Greening of Food and Beverage Industries in North Carolina (EPA, Pollution Prevention, 2016-2018)


PI: Dr. Tarek Abdel-Salam

 

This project will address one of the P2 National Emphasis Area, “Food Manufacturing and Processing: Implement P2 projects to support more sustainable food manufacturing and processing resulting in reduced greenhouse gas emissions, water usage, hazardous materials generation and use, and/or business costs.” The project will:

    Make available specific technical assistance to food and beverage industries in North Carolina seeking information about source reduction opportunities, including providing on-site technical advice to assist in the development of source reduction plans.

    Target assistance to food and beverage industries in North Carolina for whom lack of information is an impediment to source reduction.

    Provide training in source reduction techniques.

    Organize seminars/discussion sessions on pollution source reduction and production waste reduction.

 

Investigating Drivers of Storm water Flooding in Coastal Communities: A Citizen in Science Project (NSF Eager grant) 

PI: Dr. Randall Etheridge

The project will investigate the coastal communities on Bogue Banks that frequently experience flooding after significant precipitation events. Etheridge will work with town managers to employ engineering solutions to alleviate the effects of storm water flooding events using both scientists and citizens for data collection.

 

Participatory Mapping of Surface Water Hydrology as an Initial Step in the Restoration of Lake Mattamuskeet (DOI US Fish and Wildlife Service) 


PI: Dr. Randall Etheridge

 

Lake Mattamuskeet is a natural lake system located on the Albemarle-Pamlico Peninsula on the coast of North Carolina. The 40,000-acre Lake Mattamuskeet is the centerpiece of the U.S. Fish and Wildlife Service (USFWS) Mattamuskeet National Wildlife Refuge (NWR), which provides habitat for wintering waterfowl and other migratory birds. Mattamuskeet NWR annually supports a significant percentage of wintering waterfowl in the Atlantic Flyway. Lake Mattamuskeet has historically contained dense beds of submerged aquatic vegetation that provide food for swans, diving ducks, and puddle ducks and important habitat for fish, but declines in water quality are most likely the cause of recent reductions in submerged aquatic vegetation coverage in the lake. The declining water quality and loss of submerged aquatic vegetation are serious concerns to the citizens of Hyde County and the Refuge. The resources, sport, and recreational opportunities provided by Lake Mattamuskeet are important for the community and the local economy.

Despite its status as a National Wildlife Refuge, Lake Mattamuskeet has a long history of human alteration. Understanding the causes and potential corrections for water quality concerns is complicated because of the lake’s large surface area (41,000 acres), extensive shoreline (72 miles), shallow depth (average of 1 meter), and long history of hydrological alteration. In addition, many adjacent land owners farm and/or manage duck impoundments that drain into the lake and can periodically be flooded by the lake during times of high water. Agricultural production and the waterfowl impoundments are vital to the area’s economy, but their impact on the lake ecosystem is unknown.

The Refuge and community have an immediate need to improve their understanding of the complex hydrology in the region in order to develop a plan for improving water quality and restoring submerged aquatic vegetation. Due to the flat landscape and the substantial human alterations, understanding the hydrology in the watershed is nearly impossible without community input. In addition, this project will seek input from community members at the beginning of the solutions planning process as any proposed changes must be sustainable for the lake and community.

 

Building Net Zero Energy Sustainable Communities (Constellation, E² Energy to Educate grant)

  

PI: Dr. Ranjeet Agarwala  

 

The program is for student projects focusing on energy science, technology, and education. This project will educate and inspire students on the significance and societal benefits of sustainability and renewable energy in the preservation of environment and natural resources through a hands-on solar technology project. Around 150 students from the College of Engineering and Technology (CET) will partner with International Green Construction Code (IGCC) to develop and deploy renewable energy sustainable systems with a goal to build a net zero energy facility.
