The Crassostrea Virginica, also known as the Eastern Oyster, is one of natures oldest and most efficient filters. A single Eastern Oyster is capable of cleaning 50 gallons of water per day--easily more than one-hundred times its own volume. All the contaminants digested by the oyster are expelled into small pellets, which eventually re-enter the atmosphere as nitrogen.

NEW-AGE SYSTEM
URBAN DEGRADATION ABSTRACT Boston harbors have been contaminated and uninviting to people and animals in recent history. Also, as a historical city, Boston's historical footprint is too small for growth. Through integrating a natural filter--the oyster--into an architectural design of a building sited on water, the project creates space within the dense urban fabric, decontaminates and filters the water of the harbor to a livable level, and reintroduces an important niche of Boston’s natural ecological system.

Generally a process that occurs in disparate processes, the Eastern Oyster is harbored and nurtured in a series of tanks for about two weeks before they are ready to be introduced to their natural habitat. Once they find a desirable surface to attach to (usually a hard substrate--other older oyster shells are an excellent candidate!) In the next two to five years, the oyster will grow to its full adult stage.

OYSTER SHELL RECYCLED
DESIGN CONCLUSION The architecture of the Urban Vertical Aquaculture System organizes the oyster nurturing process into a series of vertical tanks. Oysters move from tank to tank in their step by step growth until they are finally ready to be deployed into the Fort Point Channel in an effort to not only clean the heavily contaminated waters, but also reinvigorate the natural ecology of the highly constructed site. The rest of the design hosts programs sponsored by an interst in ecological revitalization and urban redevelopment, and invites the public into the building via an architectural extension of the Harborwalk which exposes the entire process to the city of Boston.
