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.

Amsterdam is Turning Plastic Trash Into 3D-Printed Furniture

PrintYourCity

The city of Amsterdam in the Netherlands is taking a unique approach to waste management, Inhabitat reports. Under the direction of The New Raw, a Rotterdam-based design studio, recycled plastic is being used to make public benches that capture a lot of the area’s charm while providing solutions for the 51 pounds of plastic refuse each Amsterdam resident tosses away each year.

The initiative is called Print Your City! and encourages those materials to be repurposed via 3D printing to make new, permanent fixtures. The New Raw calls it a “closed loop” of use, where the plastic is used, reused, and materialized in the same environment. The bench, dubbed XXX, seats two and rocks back and forth with the sitters' movements, offering a metaphor for the teamwork The New Raw is attempting to cultivate with the general public.

“Plastic has a major design failure,” says Panos Sakkas, an architect with The New Raw. “It’s designed to last forever, but it’s used only for a few seconds and then easily thrown away.”

The goal is to collect more plastic material in the city to use for projects that can be designed and implemented by citizens. In the future, 3D printing may also support bus shelters, waste bins, and playground material—all of it recyclable.

To Encourage Responsible Trash Disposal, a Startup in Nigeria Pays People for their Waste

Nigeria is home to more than 180 million people, who produce more than 32 million tons of waste per year and just 20 to 30 percent of this garbage is collected, according to one estimate. To provide Nigerians with incentive to dispose of their trash responsibly, Junks, a Nigerian waste management startup, provides people with the chance to exchange their trash for cash, according to Konbini.

The company offers to pay for items and materials like discarded electronics, glass, plastic, aluminum, books, and clothes. Once purchased, these materials are re-sold to wholesalers and recycling companies, according to Techpoint. Potential users who want to sell their trash are required to register on the startup's website, Junks.ng, and fill out a form with a description of the trash they're selling, along with their asking price and contact information. Once this information is received, representatives from Junks are sent to pick up and pay for the waste.

Computer programmer Bradley Yarrow founded Junks.ng in August 2017. Based in Port Harcourt, the capital of Rivers State, Nigeria, the company currently has just three employees, in addition to Yarrow. That said, the tiny startup appears to be doing big business, judging from a growing list of sold junk—which includes laminating machines, old laptops, and scrap car parts—already listed on Junks.ng.
