Banana circle is a permaculture design that exemplifies the partnership between edible plants and waste. In a banana circle, different elements provide mutual benefits for each other. The design involves establishing a pit, fill it with organic waste and preferably link it with filtered grey water from bathrooms and/or kitchen. Then around the pit, plant different edible plants. Grey water from kitchen and or bathroom often becomes a nuisance in regards to disposal method due to chemicals contained in soaps and other household products. The disposal of this water has an effect on the water quality, potential harm to soil microbes and negative effects to various biodiversity forms.

When grey water flows at the top, it flows through these layers and by the time it passes through the bottom, is free from chemicals found in soaps. The water is safe for use in growing crops in banana circle model.
