Project(s):
Gulf Coast - Center for Addressing Microplastics Pollution (GC - CAMP): Understanding, mitigation and prevention of waste plastic marine debris in the Gulf Coast

Relevance

Microplastics in wastewater are an emerging threat to coastal ecosystems and public health, yet data on their presence in Gulf of America treatment facilities were lacking. This project addressed a critical knowledge gap, aligning with Sea Grant's goals to protect water quality and support sustainable infrastructure. Local stakeholders concerned about marine debris and its long-term impacts identified the need for innovative removal, reuse and monitoring strategies.

Response

Sea Grant supported a collaborative research initiative involving over 20 researchers from universities and environmental organizations across Alabama, Mississippi and Florida. The team conducted sampling at wastewater treatment facilities, developed microplastic removal technologies using biochar, explored reuse in construction materials and designed monitoring systems. Key partners included academic institutions and utility operators, coastal communities and agencies. The primary audience included environmental managers, engineers and policy makers working to reduce microplastic pollution in coastal communities.

Results

The project improved understanding of microplastic pollution in wastewater systems across the Gulf Coast, informing local and regional strategies for marine debris reduction. Beneficiaries include utility operators, environmental agencies, general public and coastal communities. Data were collected through field sampling and lab analysis at treatment facilities in Alabama, Mississippi and Florida. Findings support technology adoption and policy development, contributing to healthier ecosystems and next-generation marine debris workforce development.

Recap

The project has addressed the data gap on microplastics in wastewater treatment facilities across three Gulf of America states: Alabama, Mississippi and Florida. The project team engaged over 20 researchers in a collaborative effort to tackle microplastic marine debris. It also developed technologies including the use of biochar for microplastic removal, incorporation of microplastics into construction materials, and development of monitoring systems.
