NH Marine Debris to Energy Project

A New Hampshire-based project to study marine debris at sea and on the shore, incorporating waste-to-energy and recycling as part of cleanup efforts.

Marine Debris-to-Energy Project Expands

We are excited to announce New Derelict Gear Bin at Portsmouth Commercial Fish Pier with Project Partnersthat on April 14, 2010, 3 new derelict fishing gear bins were opened, thus expanding the Marine Debris to Energy project and making bins available to fishermen in Seabrook (Yankee Fishermen's Co-op), Rye (Commercial Fish Pier at Rye Harbor), Portsmouth (Portsmouth Commercial Fish Pier) and Newington (Little Bay Lobster Company). 

The addition of the new bins, with the support of Waste Management, Wheelabrator, NH Port Authority and Atlantic Offshore Lobstermen's Association, will lead to responsible disposal of thousands of pounds of derelict gear. This, in turn, will keep more derelict fishing gear out of the environment, where it could be hazardous to wildlife and people.

About the Project

debris1.jpgThe star attraction at a ceremony held at the Yankee Fishermen's Cooperative in Seabrook April 18, 2008 was a dumpster. But this dumpster had a special assignment--collecting marine debris, abandoned fishing gear and other items that can harm the marine ecosystem.

When it's full, the dumpster will be hauled to a waste-to-energy plant, where the debris will be burned to make electricity.

The ceremony launched The NH Marine Debris-to-Energy Project. Funded by a grant from the NOAA Marine Debris Program, the project aims to:

  • Better characterize the sources and distribution patterns of ocean-based debris, especially "derelict fishing gear" (DFG)--nets, lines, pots, and other fishing equipment that has been lost, abandoned, or discarded in the marine environment. DFG is an extremely dangerous form of marine debris.
  • Develop protocols for undertaking a unique underwater cleanup program to identify and remove DFG and other debris.
  • Continue to investigate the sources of land-based debris.
  • Mitigate the problem through education and outreach.

On hand at the Seabrook kick-off ceremony were the project's primary investigators: Ken La Valley, commercial fisheries specialist with UNH Cooperative Extension Sea Grant, and Jenna Jambeck, a UNH research assistant professor of civil/environmental engineering, as well as representatives from partner organizations: Jen Kennedy, director of the nonprofit Blue Ocean Society for Marine Conservation, and Alan Davis, district manager for Waste Management.

In his remarks, La Valley noted that getting the help of local fishermen 'wasn't a tough sell."

New Hampshire Congresswoman Carol Shea-Porter congratulated the project coordinators and Waste Management for joining forces, noting it showed a maturation of the environmental movement by demonstrating, "we can find the answers by working together."

Main project activities

  • Researchers will make an initial assessment of the volume of underwater marine debris using sonar for the first time for this purpose in New Hampshire.
  • Commercial and recreational fishermen will become actively involved in removing DFG at sea and collecting it in the Waste Management dumpster at the Yankee Fisherman's Co-op.
  • Fishermen will have access to bins where they can discard their fishing line for recycling.
  • Anyone collecting marine debris will be able to report it online via an easy Web interface.
  • Cleanups along the New Hampshire coastline will expand, involving more volunteers and creating more aesthetically-pleasing, healthier and safer beaches.
  • Members of the public, schools, and scientific researchers will have access to interactive marine-debris data and GIS maps.
  • Teachers and their students across the world will have access to marine-debris data to use in their lessons, and local schools will be able to work directly with project investigators and partners in viewing data, participating in cleanups and contributing to the database.
  • Project staff and others around the world can use the data and protocols developed in this project to target further pollution-prevention and outreach efforts.
  • The quantities of debris in the ocean and on the shore, potentially harmful to wildlife, people, vessels, and the economy, will diminish.

More information Marine Debris to Energy is a project that takes a holistic approach to marine debris by tracking and cleaning up marine debris on the shore, underwater, and on the ocean. A large component of this project involves collecting derelict fishing gear at a collection bin and at monofilament recycling bins along the coast and converting it into energy via a waste-to-energy plant in New Hampshire. The project will also provide a collection point for data from beach cleanup volunteers, commercial and recreational fishermen, and other users of the coastline to report marine debris. Users of the site will be able to generate reports and maps to learn more about marine debris along the New Hampshire coast and in the Gulf of Maine.More...
