Permaculture is a form of agriculture that attempts to work with natural systems. Permaculture makes use of features of a landscape, properties of soils, and living systems within an ecosystem.

Greenway Environmental Services operates a composting facility in upstate New York, and works with local governments to treat storm water in the Hudson Valley. Nearly every aspect of their work relates to permaculture: making dirty water clean, using waste for microbial food, working with living systems.
