The Green Center, Inc.
The Green Center, Inc., a non-profit research and educational organization,
carries on the original purposes of the New Alchemy Institute (1971-1991),
including “ … to provide educational information and instruction on methods
to reduce environmental contamination and to restore natural waters and
landscapes.”
"Among our major tasks is the creation of ecologically derived human support
systems - renewable energy, agriculture aquaculture, housing and landscapes.
The strategies we research emphasize a minimal reliance on fossil fuels and
operate on a scale accessible to individuals, families and small groups. It is our
belief that ecological and social transformations must take place at the lowest
functional levels of society if humankind is to direct its course towards a
greener, saner world."

greenhouse. The house has waterless composting toilets, solar electricity,

strategies suited to Cape Cod‘s conditions.
