From Seafood Waste To Sustainable Style: How One Woman Is Turning Shellfish Shells Into Chic Design Pieces

An inspiring story from Rhode Island is shining a light on how ingenuity and environmental awareness can transform waste into beauty. Felicia Neuhof, a designer-turned-entrepreneur, is reimagining the life of discarded shellfish shells by converting them into stunning, eco-friendly tiling and furniture through her venture, Shellf Life. 

This innovative effort isn’t just a creative passion project — it’s offering a sustainable alternative to wasteful industry practices along the Mid-Atlantic coastline.

The Mid-Atlantic is known for its rich culinary traditions centered around seafood like mussels, oysters, clams, scallops, and crabs. While these delicacies delight diners, they leave behind an inconvenient consequence: millions of pounds of shell waste each year. Typically, these discarded shells end up in landfills, contributing to growing waste management concerns.

This abundance of organic, mineral-rich material prompted Neuhof to ask an important question: what if these shells could be repurposed instead of discarded? Having previously worked for major design firms in Boston and New York City — environments she observed producing large amounts of plastic waste — Neuhof decided to pursue a more eco-conscious path. Rather than perpetuate the problem, she set out to be part of the solution.

Neuhof, originally from Vermont, began experimenting with shell-based design materials in the most modest of laboratories: her own kitchen. She developed a processing method capable of transforming discarded shells into bespoke design elements and custom-made furniture. The results were so promising that she eventually expanded her operation, moving from a stovetop workshop to a micro-lab in Providence.

Her breakthrough came when she entered and won the Terra Carta Design Lab Contest, an international competition organized under the patronage of King Charles III. The victory provided Neuhof with vital funding for research and development, enabling her to refine her production techniques and scale up her operations.

The potential of Shellf Life’s model is immense, and Neuhof has the numbers to prove it. The Mid-Atlantic states, though modest in size, sustain highly productive shellfish industries. “New England’s annual shell waste — currently headed to landfills — could tile nearly 300 homes every year,” she explained.

To put it into perspective, Neuhof told the Boston Globe that a single processor in Rhode Island produces enough shell waste each year to create 30,000 square feet of tiling — equivalent to around 330,000 tiles. In Massachusetts, one processor’s waste output could produce material for 5,000 bathroom floors annually, while a smaller New Hampshire processor could supply enough for 1,000 shower surrounds.

Beyond their eco-friendly nature, the tiles themselves are aesthetically striking. Each type of shell lends a unique texture and finish to the final product. Providence mussels provide a look reminiscent of granite, while local clams yield a rough texture akin to unrefined sea salt. Neuhof’s idea has global potential as well, with Kyoto abalone producing a dazzling effect with its shimmering flakes and Azores limpets glittering with mother-of-pearl-like iridescence.

Central to Shellf Life’s operation are the relationships Neuhof has fostered with local aquaculturists and restaurants. At the City Island Oyster Reef, she’s collaborating to repurpose discarded shells into concrete for sea walls and shellfish farms, offering a sustainable solution for shoreline restoration projects.

Among Providence’s restaurants, Neuhof has simplified participation by providing Shellf Life-branded collection bins, which she picks up personally. This grassroots approach is both practical and community-driven. She hopes to expand these efforts by establishing public collection points so residents can contribute as well — even after casual backyard clam bakes.

“My goal has been to develop a system so refined that making a tile is as easy as flipping burgers, opening up manufacturing opportunities to anyone regardless of educational background,” she stated, emphasizing her vision of accessibility and inclusivity in sustainable design.

Shellf Life’s concept joins a growing international movement of creatives turning food waste into functional, stylish, and sustainable products. In Milan, for instance, a startup called Krill collects coffee grounds and orange peels from the bustling café scene to create a patented 3D-printing gel named ReKrill. Their innovative material is already in use by high-profile brands like San Pellegrino and Four Seasons.

In Taiwan, textile manufacturers have pioneered “sea wool,” an unusual fabric additive made by pulverizing the shells of bivalves such as mussels — another testament to the untapped potential of ocean byproducts.

Felicia Neuhof’s work is a reminder of how sustainability and design can coexist, blending environmental stewardship with artful craftsmanship. Through Shellf Life, she has shown that waste can become a valuable resource, offering both beauty and function while addressing one of the seafood industry’s most persistent environmental issues. And as she scales up her operations and inspires other innovators globally, her vision for a circular, waste-free economy continues to gain momentum.
