Turn them into cycles Permaculture systems seek to stop the flow of nutrient and energy off the site and instead turn them into cycles, so that, for instance, kitchen wastes are recycles to compost; animal manures are directed to biogas production or to the soil; household greywater flows to the garden; green manures are turned into the earth; leaves are raked up around trees as mulch.
