  • Publication number: 20170007082
    Abstract: A waterless composting toilet comprises a seat, a solid waste transfer vessel, two waste containers for separating the liquid and the solid waste. The seat bowl has a liquid outlet in the front and a large opening in the back for solid waste transfer. The solid container has a venting system on the top, a humidity-providing liquid container at the bottom and a set of porous plates inside the container to create a multi-layer composting space. The transfer vessel is controlled manually through a mechanical assembly and serves either a waste receptor when the toilet is in use or a container lid after the waste is transferred into the container. The vessel is supplied with a bed of peat moss prior to use to keep the solid waste separating and spreading inside the container. The toilet provides sufficient aeration for waste decomposition without physically mixing of waste and is suitable for both private and public sanitation.
