Oyster Oyster turns Champagne bottles into ceramics

How it works: Rubba procured a $10,000 AquaTools crusher that turns the restaurant's spent bottles into a fine, glassy sand.

• The ceramicists at Material Things Studio near Hyattsville, Md., transform the sand into plates by baking it in a clay mold.

Zoom in: Oyster Oyster's first line of plates are used for snacks in the tasting menu, accompanied by a glass of Ruinart Blanc Singulier — a new climate change-minded release from France's oldest Champagne house.

Between the lines: The machine is no small expense for a tiny, independent venture like Oyster Oyster — but there are other reasons to do it besides upcycling tableware.

• The process makes bottles more easily recyclable, reducing their volume by around 90%, according to the manufacturer. The process also requires fewer fuel-consuming pick-ups.

What they're saying: "You'll often see these machines marketed towards hotels and larger restaurants — imagine how much glassware they're going through," says Rubba. "For us, we want to have control of our waste."

What's next: More plates! Potentially for purchase alongside the restaurant's other sustainable efforts like homemade candles fashioned from local beeswax and filtered cooking oil. And (fingers crossed) that addictive marigold butter.
