Abstract
Abstract A method of disposing of refuse which comprises wetting nominally heterogeneous and at least partly dry refuse with water, compressing the moistened refuse, and freezing the moistened, compacted refuse into solid pellets.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
101 words
A method for disposing of nominally heterogeneous and at least partly dry refuse comprising the steps of: dumping said refuse in random disarray normally having voids therein at a disposing station; moistening said refuse with water at said station; compressing said moistened refuse substantially to eliminate voids and to bring the components of said refuse into close contiguous relation whereby said refuse forms a compacted structure at said station; draining the excess water from said moistened refuse simultaneously as the refuse is being compressed, freezing said moistened, compacted structure at said station while maintaining pressure thereon at least at the start.
Claim 2
Independent Claim
101 words
A method for disposing of nominally heterogeneous and at least partly dry refuse comprising the steps of: dumping said refuse in random disarray normally having voids therein at a disposing station; moistening said refuse with water at said station; compressing said moistened refuse substantially to eliminate voids and to bring the components of said refuse into close contiguous relation whereby said refuse forms a compacted structure at said station; draining the excess water from said moistened refuse simultaneously as the refuse is being compressed, freezing said moistened, compacted structure at said station while maintaining pressure thereon at least at the start.
Claim 3
Dependent Claim
32 words
A method for disposing of refuse as claimed in claim 1 further including the step of storing the frozen, compacted refuse structure in a freezer chamber to await the ultimate disposition thereof.
Claim 4
Dependent Claim
30 words
A method of disposing of refuse as set forth in claim 1 wherein the step of compressing the refuse comprises compressing the refuse between a ram and a back-up member.
Claim 5
Independent Claim
123 words
A method of storing compactable and freezable waste comprising the steps of: dumping said waste in random disarray normally having voids therein at a disposing station; adding sufficient water at said station if necessary to freeze said waste into a coherent block; applying a compressive force to the waste at said station substantially to eliminate voids and to bring the components of said waste into close contiguous relation in order to compact said waste into a dense mass of a predetermined geometric shape; draining any excess water from said waste; removing sufficient thermal energy from said waste so as to cause said dense mass to retain its compact geometric shape; and storing said waste at a temperature below the freezing point of water.
Claim 6
Independent Claim
123 words
A method of storing compactable and freezable waste comprising the steps of: dumping said waste in random disarray normally having voids therein at a disposing station; adding sufficient water at said station if necessary to freeze said waste into a coherent block; applying a compressive force to the waste at said station substantially to eliminate voids and to bring the components of said waste into close contiguous relation in order to compact said waste into a dense mass of a predetermined geometric shape; draining any excess water from said waste; removing sufficient thermal energy from said waste so as to cause said dense mass to retain its compact geometric shape; and storing said waste at a temperature below the freezing point of water.
