Abstract
Abstract A biological toilet and an organic material recycling method in which human liquid and solid waste (i.e., excrement) and cellulosic material and, optionally, kitchen waste (i.e., food and paper scraps and the like kitchen garbage) are deposited into a receptacle and carried by pressure differential into a recycling or composting container wherein, by the application of environmental factors, including moisture, air, warmth and certain bacteria and worms (such as Eisenia Foetida, the red worm) and other wormlike organisms, the organic material is composted or digested and reacted upon to produce a pleasant smelling, uniform, well granulated substantially neutral, active, compost-like plant nutritional material available for easy distribution.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
323 words
A continuous process for converting human wastes and cellulosic material into a non-odiferous soil-like composted material, to provide means for disposing large quantities of these materials without polluting the environment, comprising the steps of: (a) depositing human and liquid wastes in a first chamber; (b) depositing water into said first chamber to dilute said human wastes and to clean the surfaces of said first chamber; (c) providing a second chamber, said second chamber being connected to said first chamber by valved conduit means; (d) filling said second chamber from about 1/10 to about 1/2 full with cellulosic material or with a mixture of cellulosic material and topsoil, the volume ratio of cellulosic material and topsoil being from about 6:1 to about 1:1 when a mixture of cellulosic material and topsoil is used; (e) seeding earth worms into said cellulosic material or said mixture of cellulosic material and topsoil in said second chamber; (f) transferring said human wastes, diluted in step (b), from said first chamber to said second chamber, said wastes being transferred through said valved conduit means by differential pressure; (g) periodically depositing a layer of cellulosic material on top of the diluted human waste transferred to said second chamber, the volume ratio of said layer of cellulosic material ranging from about 1:2 to about 3:1 relative to the volume of said diluted human wastes; (h) selectively exposing the contents of said second chamber to warm natural air convection at a temperature from about 50° F. to 100° F. and a humidity of from about 30 to about 100%, except when said transferring step (f) is in progress; (i) draining excess liquid, if any, from said second chamber; (j) allowing the earth worm hatching cycle and rebirth to proceed in said second chamber; and (k) periodically removing from the lower portion of said second chamber a soil-like material comprised of worm-reacted human waste, water, cellulosic material, worm capsules, worms and worm castings.

Claim 3
Dependent Claim
22 words
The process of claim 1, wherein, in addition to said human wastes, ordinary household garbage is added randomly with said human wastes.
Claim 4
Dependent Claim
49 words
The process of claim 1, wherein said cellulosic material in step (g) is added to said second chamber in approximately equal parts by weight on a solids basis relative to said human excreta, and wherein said earth worms added in step (e) are of a class called Eisenia Foetida.
