Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
A method of sanitarily disposing of refuse to reduce pollution, vermin, and other undesirable concomitants of refuse disposal facilities, comprising the steps of: a. unloading the refuse from a refuse collection vehicle in which the refuse has been transported to the disposal site; b. depositing the refuse in a substantially impermeable cylindrical solution cavity having a greater vertical depth dimension relative to the diameter dimension thereof and being formed within a subterranean rock salt formation; c. accumulating the refuse in the cylindrical cavity, wherein the dimensions of the cavity allow substantially complete filling of the cavity efficiently utilizing the volume of the cavity; d. extracting the air containing noxious odors and excess heat generated by the decomposition of such refuse in the solution cavity; e. purifying the air extracted from such solution cavity; and f. releasing the purified air into the atmosphere.
Claim 2
Independent Claim
142 words
A method of sanitarily disposing of refuse to reduce pollution, vermin, and other undesirable concomitants of refuse disposal facilities, comprising the steps of: a. unloading the refuse from a refuse collection vehicle in which the refuse has been transported to the disposal site; b. depositing the refuse in a substantially impermeable cylindrical solution cavity having a greater vertical depth dimension relative to the diameter dimension thereof and being formed within a subterranean rock salt formation; c. accumulating the refuse in the cylindrical cavity, wherein the dimensions of the cavity allow substantially complete filling of the cavity efficiently utilizing the volume of the cavity; d. extracting the air containing noxious odors and excess heat generated by the decomposition of such refuse in the solution cavity; e. purifying the air extracted from such solution cavity; and f. releasing the purified air into the atmosphere.
Claim 3
Dependent Claim
25 words
The method of claim 1, further including the step of: compressing the lower layers of refuse in the cavity with the more recently introduced refuse.
Claim 4
Dependent Claim
25 words
The method of claim 1, further including the step of: transporting the refuse from the vehicle to a disposal shaft leading to the solution cavity.
Claim 5
Dependent Claim
25 words
The method of claim 1, further including the step of: magnetically separating metallic elements from the refuse before depositing such refuse in the solution cavity.
Claim 6
Dependent Claim
28 words
The method of claim 1, further including the step of: compressing the refuse into bales before said step of depositing to reduce the volume occupied by such refuse.
Claim 7
Dependent Claim
26 words
The method of claim 1, further including the step of: introducing aerobic and anaerobic bacteria into the cavity to decompose the refuse in the solution cavity.
Claim 8
Dependent Claim
26 words
The method of claim 1, further including the step of: shredding the refuse before said step of depositing to reduce the volume occupied by such refuse.
