“The most dramatic tactic for reclaiming lost mineral nutrients and saving water in the house is to dispense with the use of a flush toilet and purchase or build a composting toilet”.1Thus, composting is an important technique for recycling human body wastes to make the building sustainable. Rikard Lindstrom designed the clivus toilet with large concrete tank and chimney in 1964 to recycle human body waste and explore the whole cycle of the waste. 2 “The tank is positioned on an inclined rack under the floor in a crawl space, or in a basement beneath the bathroom”. 3 The waste from the bathroom and kitchen is composted here, making the tank become the active part. Through the system, the gas is produced and the garden soil is also benefitted after depositing the waste. Waste was developed into a more wide using recycle where it can be regarded as resource. Because the energy is limited in the Earth, how to use it via a more efficient way is what we should consider to make the Earth sustainable. Although the toilet is an extremely small element in the whole system on the Earth, the change always happen from the basic. We can’t regard elements separately and partially. Although the form may change, it always exist in the flow and influence the whole.
