Restaurants Recycle Oyster Shells to Revitalize Ocean Reefs

Oysters are more than a tasty appetizer. The mollusks are key players in healthy marine environments. The filter-feeders improve water quality, and their beds provide habitat for fish and other underwater critters. Oyster beds also improve life out of the water, preventing coastal erosion and creating a buffer against large waves.

As oysters’ role in maintaining a vibrant coastal ecosystem becomes more clear, environmental groups are trying to bring back devastated oyster populations. In some places, this means getting restaurants to recycle their leftover oyster shells to put back into the ocean instead of sending them to a landfill, according to Fast Company.

This is particularly important along the Gulf Coast, where the Alabama Coastal Foundation (ACF) set up a recycling program in 2016 to collect used oyster shells from local eateries. According to The Nature Conservancy, 67 percent of the U.S. oyster harvest comes from the Gulf of Mexico [PDF]. The Nature Conservancy has been working throughout the Gulf of Mexico to restore oyster populations.

So far, the effort in Alabama, a partnership between the waste collection company Republic Services and the ACF, has collected enough oyster shells to cover 7.2 acres of sea floor. The program is currently funded by a grant from the National Fish and Wildlife Foundation and is free to restaurants, though that may change in the future.

Alabama isn’t the only place oyster shells are becoming a hot commodity. In New York City, the Billion Oyster Project is working to restore oyster populations and reefs in New York Harbor, in part to make Staten Island more resilient to superstorms and flooding. (Hurricane Sandy ravaged the island's east and south shores in 2012.) In New Jersey, the American Littoral Society is seeding local waterways with new oysters in Barnegat Bay in hopes of both restoring the once-vibrant oyster harvesting industry there and cleaning the waterways. Other oyster repopulation projects are ongoing in the Chesapeake Bay and along the Gulf Coast from Florida to Texas. On the West Coast, the Puget Sound Restoration Fund plans to restore 100 acres of native oyster habitats by 2020.

However, oyster habitat restoration isn’t as easy as it sounds. In a 15-year study of Rhode Island’s oyster restoration programs, the oysters had such a high mortality rate that populations began declining immediately when the programs stopped actively re-seeding the beds with new oysters. Another worldwide study found that the median survival rate for oyster bed restoration projects was only 56 percent.

As many current oyster restoration projects are just gaining steam, it may be years before we find out if they can be as effective as natural oyster beds.

A LEGO Brick Could Survive In the Ocean for Up to 1300 Years

As any parent who has ever walked through their house in bare feet knows, LEGO bricks are among the most resilient objects on the planet. Able to withstand years of manipulation and abuse, the sets remain intact even when doll heads, action figure limbs, and electronic games fall by the wayside.

If you needed further confirmation on their durability, science is here to help. New research from the University of Plymouth in the UK published in the journal Environmental Pollution demonstrates that the bricks could survive in some form for as long as 1300 years in the ocean. Not even constant exposure to saltwater can stop them.

This projection was determined by researchers collecting LEGO bricks that had washed ashore in Southwest England. They compared the mass of these found bricks to similar LEGOs taken from storage. The 50 pieces, which are made of acrylonitrile butadiene styrene (ABS) plastic, were retrieved from outdoor saltwater exposure to be washed, weighed, and measured. Their approximate age was estimated by using an X-ray fluorescence spectrometer to see which chemical elements were missing. A rate of deterioration was made based on their condition relative to the stored bricks.

The result? LEGO bricks could hold on to some semblance of shape for anywhere between 100 to 1300 years. While not necessarily usable—some of the pieces decayed into blobs of plastic—researchers were able to demonstrate that microplastics can endure in the environment for indefinite periods.

“The pieces we tested had smoothed and discolored, with some of the structures having fractured and fragmented, suggested that as well as pieces remaining intact they might also break down into microplastics,” Andrew Turner, the lead author and associate professor of environmental sciences at the University of Plymouth, said in a statement. “It once again emphasizes the importance of people disposing of used items properly to ensure they do not pose potential problems for the environment.”
