Abstract

Abstract An aerobic-anaerobic composting device and method of composting organic waste materials. The composting device disclosed is a free-standing rotatable wheel which has an open mesh material on its exterior sides and ends. After the organic waste material is placed in the wheel, a removable cover is placed over the open mesh material on the sides of the wheel and the wheel is rotated periodically to mix and aerate the contents with a tumbling action. The cover retains the material in the wheel and also protects it from the weather. Fertilizers or other chemicals of high nitrogen content may be added to the waste material in the wheel to promote its decomposition. After the composting has been completed, the cover is removed and the composted material is discharged by rotating the wheel. For anaerobic treatment, the wheel is not rotated and a second cover is placed over the material in the wheel and the ends of the wheel are closed to restrict the flow of air. After such treatment, the inner and outer covers are removed and the contents of the wheel are discharged, as required, by rotation of the wheel.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 104 words
The method of composting organic waste material which comprises the steps of: a. placing organic waste material in a rotatable container having open mesh sides; b. covering the open mesh sides of the container with a removable outer cover of moisture proof material; c. periodically rotating the container about a horizontal axis with the cover in place and the waste material therein; d. said rotation mixing the material in the container and exposing said material to contact with air; e. removing said outer cover and continuing rotation of the container thereby discharging decomposed composted material from the container through the open mesh sides thereof.
Claim 2
Independent Claim 104 words
The method of composting organic waste material which comprises the steps of: a. placing organic waste material in a rotatable container having open mesh sides; b. covering the open mesh sides of the container with a removable outer cover of moisture proof material; c. periodically rotating the container about a horizontal axis with the cover in place and the waste material therein; d. said rotation mixing the material in the container and exposing said material to contact with air; e. removing said outer cover and continuing rotation of the container thereby discharging decomposed composted material from the container through the open mesh sides thereof.
Claim 3
Independent Claim 156 words
THE METHOD OF COMPOSTING ORGANIC WASTE MATERIAL WHICH COMPRISES THE STEPS OF: A. PLACING ORGANIC WASTE MATERIAL IN A ROTATABLE CONTAINER HAVING OPEN MESH SIDES; B. COVERING SAID OPEN MESH SIDES OF THE CONTAINER WITH A REMOVABLE OUTER COVER OF MOISTURE EXCLUDING MATERIAL; C. PERIODICALLY ROTATING THE CONTAINER ABOUT A HORIZONTAL AXIS WITH SAID OUTER COVER ATTACHED AND THE WASTE MATERIAL THEREIN; D. SAID ROTATION MIXING THE MATERIAL IN THE CONTAINER AND EXPOSING SAID MATERIAL TO CONTACT WITH AIR; E. DISCONTINUING SAID PERIODIC ROTATION OF THE CONTAINER. F. PLACING AN INNER SECOND COVER OVER THE MATERIAL WITHIN THE CONTAINER; G. SAID INNER COVER DIRECTLY CONTACTING WITH THE MATEIAL IN EXPOSING SAID MATERIAL TO CONTACT WITH AIR; SAID MATERIAL; H. THEN REMOVING BOTH SAID INNER AND OUTER COVERS AND CONTINUING ROTATION OF THE CONTAINER WITH THE COVERS REMOVED; I. SAID CONTINUED ROTATION EFFECTING DISCHARGE OF COMPOSTED WASTE MATERIAL FROM THE CONTAINER THROUGH THE OPEN MESH SIDES THEREOF.
Claim 4
Independent Claim 156 words
THE METHOD OF COMPOSTING ORGANIC WASTE MATERIAL WHICH COMPRISES THE STEPS OF: A. PLACING ORGANIC WASTE MATERIAL IN A ROTATABLE CONTAINER HAVING OPEN MESH SIDES; B. COVERING SAID OPEN MESH SIDES OF THE CONTAINER WITH A REMOVABLE OUTER COVER OF MOISTURE EXCLUDING MATERIAL; C. PERIODICALLY ROTATING THE CONTAINER ABOUT A HORIZONTAL AXIS WITH SAID OUTER COVER ATTACHED AND THE WASTE MATERIAL THEREIN; D. SAID ROTATION MIXING THE MATERIAL IN THE CONTAINER AND EXPOSING SAID MATERIAL TO CONTACT WITH AIR; E. DISCONTINUING SAID PERIODIC ROTATION OF THE CONTAINER. F. PLACING AN INNER SECOND COVER OVER THE MATERIAL WITHIN THE CONTAINER; G. SAID INNER COVER DIRECTLY CONTACTING WITH THE MATEIAL IN EXPOSING SAID MATERIAL TO CONTACT WITH AIR; SAID MATERIAL; H. THEN REMOVING BOTH SAID INNER AND OUTER COVERS AND CONTINUING ROTATION OF THE CONTAINER WITH THE COVERS REMOVED; I. SAID CONTINUED ROTATION EFFECTING DISCHARGE OF COMPOSTED WASTE MATERIAL FROM THE CONTAINER THROUGH THE OPEN MESH SIDES THEREOF.
Claim 5
Dependent Claim 176 words
In a composting device for aerobic and anaerobic decomposition of organic waste materials the combination which comprises: a. a rotatable container having an open-mesh material covering its sides; b. said open-mesh material having a mesh size permitting decomposed material to be discharged through said mesh upon rotation of the container; c. a framework supporting said container at opposite ends thereof for rotation about a horizontal axis; d. an entry door in one side of the container for introduction of waste materials into the container; e. drive means for rotating the container about its horizontal axis; f. a removable protective cover of flexible moisture-proof material surrounding said open-mesh sides of the container and being rotatable therewith; g. said protective cover excluding rain and snow while retaining heat generated by decomposition of material within the container and permitting air to contact said material; h. a second cover within the container for preventing air from contacting partially decomposed material therein; i. said second cover being formed of a flexible material and resting directly on the material in the container.
Claim 6
Dependent Claim 176 words
In a composting device for aerobic and anaerobic decomposition of organic waste materials the combination which comprises: a. a rotatable container having an open-mesh material covering its sides; b. said open-mesh material having a mesh size permitting decomposed material to be discharged through said mesh upon rotation of the container; c. a framework supporting said container at opposite ends thereof for rotation about a horizontal axis; d. an entry door in one side of the container for introduction of waste materials into the container; e. drive means for rotating the container about its horizontal axis; f. a removable protective cover of flexible moisture-proof material surrounding said open-mesh sides of the container and being rotatable therewith; g. said protective cover excluding rain and snow while retaining heat generated by decomposition of material within the container and permitting air to contact said material; h. a second cover within the container for preventing air from contacting partially decomposed material therein; i. said second cover being formed of a flexible material and resting directly on the material in the container.
