Philly’s Shuckfest returns Sunday with 10,000...

Want to help improve Philadelphia’s waterways? Experts have this advice: Eat more oysters. 

As the summer season approaches, so does the time for peak oyster enjoyment. And there’s no better time to start slurping up those slippery suckers than this weekend. The Partnership for the Delaware Estuary (PDE), a local environmental nonprofit that works to protect the Delaware River and Bay, is teaming up with Oyster House’s Shuckfest, Philly’s annual oyster celebration. 

Together, the restaurant and nonprofit will work to recycle every single shell used at the festival, which runs Sunday from 12 to 3:30 p.m at Liberty Point at the Seaport Museum.

The PDE has spent almost a decade expanding its oyster shell recycling program. The initiative collects used shells from restaurants and repurposes them to create environmentally-friendly and beneficial reefs in the Delaware River.

“We do a lot of living shoreline work and living shoreline implementation,” said Leah Morgan, the assistant manager of estuary science at the PDE. “The reef itself is also very good at protecting the coastline from all of those risks, like storm surge, coastal flooding. So by reintroducing this material back into areas where it is typically or was once very ubiquitously found, it’s really beneficial.”

Recycled oyster shells can play a crucial part in restoring Philly’s waterways – helping improve water quality through filtration, serving as a habitat for baby oysters and protecting the shoreline from erosion. Shuckfest will be serving up thousands of shells, which will then be used in the program. 

“Each farmer will bring 800 oysters, and we have 12 local oyster farms,” said Sam Mink, the owner of Oyster House and festival organizer. “And then we have the oysters for ‘the learning how to shuck’ table, so that’s a few hundred oysters. And then we have the oysters for the shucking competition. It’s a few hundred oysters, so I would say upwards of 10,000 oysters.”

With this many mollusks on hand at the festival, this weekend is sure to not only be great for your taste buds, but also for the Delaware River’s shoreline. 

‘A full circle process’

The PDE’s oyster recycling program launched in 2016, and in the last decade the program has grown bigger and bigger – now collecting from eight different Philly restaurants and two storefronts. Last year, the organization collected a total of 134,482 pounds (more than 67 tons!) of oyster shells to return to the shoreline, which is seven times more than they were collecting in 2020. 

Picking up all these shells around town is no small feat. Ken Williamson, an oyster restoration specialist, has become the go-to guy at the PDE when it comes to collection. Twice a week he drives to restaurants around Philly and loads barrels of oysters into his Chevy Silverado pickup truck. The practice, he says, has brought some attention around town.

“I definitely do have a rapport with some of the people in some of the restaurants, or even just some of the people around the city I run into,” he said. “There’s a mailman that has a similar route in Fishtown. We’re always vying for the same parking space. And we’re like, ‘Oh, hey.’ We chat all the time now and wave at each other.”

Parking with a big truck full of oysters is no joke.

“You know, sometimes I’ll park and stop somewhere, get something to drink, or a coffee. And anybody near me, people in convertibles, are like, ‘Oh my God. What is that?’ If it’s full of shells, the smell is pretty strong in the summer.”

Once the shells are collected, they head to a management area and sit outside for at least six months to go through a curing process.

“During this curing process, the shell is exposed to the elements,” Morgan said. “It’s faced with sometimes extreme heat, sometimes extreme cold, rain, snow, sleet, any type of weather that will effectively clean the shell – in addition to bugs kind of scavenging on it and eating any leftover bacterial or biological material.”

Eventually, after enough time, each shell will be “biologically secure” enough to go back in the waterway and serve as part of a reef. There, they work their magic and help the local shoreline – improving sediment, protecting the coast, filtering the water, mitigating storm surge and expanding marsh grasses. 

What’s more, the shells work as a natural habitat for marsh animals and other critters. 

“The actual shell itself is a really great substrate for baby oysters,” Morgan explained. “So recycled oyster shell, or dead oyster shell that exists on a wild reef, is the ideal material for a larval oyster in its initial stage of life to come and latch onto and grow to an adult size and build a reef.”

“The shell reef helps them and provides protection,” she added. “It becomes a full circle process for these little guys, who will grow strong and then we can eat them and use their shells again.”
