Oyster Shell Dish Soaps

Oysters are revered as a prized delicacy, yet their shells often lack the same value and are commonly discarded—but the Gen Z entrepreneurs behind Oh Soap saw the potential to upcycle this wasted ingredient to create solid dish soap. The upcycling brand's soap-based product is inherently waste-reducing thanks to its solid form, and the integration of oyster shells helps to repurpose the hundreds of thousands of tons of oyster shells that go to waste annually.

Oh Soap's solid dish soap uses calcinated calcium―a type of chemical that's produced through exposure to high temperatures―from the shell as a key component.

All the while being sustainable and affordable, the brand's dish soap proves that upcycled products can be marketable and aesthetically pleasing.
