A major goal of New Alchemy’s research was to explore ways to produce food— local, healthy, and sufficient food— using sustainable methods that do not rely on fossil fuel and avoid chemical toxins. Inspiration and information was taken from observation of nature, learning how pre-industrial societies sustained themselves, and applying new scientific knowledge. The result is a set of ecologically derived methods of producing food: intensive vegetable production, perennial food crops, tree crops, and indoor winter food production in bioshelters.
