Abstract The invention features an apparatus and method of detoxifying and/or sterilizing waste materials utilizing ozone under pressure. The waste materials are loaded into a pressurizable chamber in which the ozone is introduced under pressure. The ozone penetrates and sterilizes and waste materials, after which the gas is evacuated from the chamber following a given treatment cycle. The evacuated gas is then fed to a second, purification chamber. Any toxic substances or contaminants that may have been released in the first waste chamber and were carried along with the evacuated gas are further purified. This is accomplished by introducing ozone into the second chamber to mix with and sterilize the evacuated waste gases. This second introduction of the ozone to purify the waste gases is an essential step of the process, and ensures that none of the toxic or contaminating substances escape to the environment.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
102 words
A method for sterilizing infectious waste material, the steps comprising: (a) loading and waste material into a pressurizable sterilization chamber; (b) introducing ozone gas under pressure into said sterilization chamber so as to penetrate and sterilize said waste material; (c) after a predetermined time cycle, evacuating gas from said sterilization chamber; (d) transferring said evacuated gas from said sterilization chamber into a purification chamber; (e) after said evacuated gas has been transferred into said purification chamber further introducing ozone gas into said purification chamber so as to sterilize said evacuated gas; and (f) removing said sterilized waste material from said sterilization chamber.
Claim 2
Independent Claim
102 words
A method for sterilizing infectious waste material, the steps comprising: (a) loading and waste material into a pressurizable sterilization chamber; (b) introducing ozone gas under pressure into said sterilization chamber so as to penetrate and sterilize said waste material; (c) after a predetermined time cycle, evacuating gas from said sterilization chamber; (d) transferring said evacuated gas from said sterilization chamber into a purification chamber; (e) after said evacuated gas has been transferred into said purification chamber further introducing ozone gas into said purification chamber so as to sterilize said evacuated gas; and (f) removing said sterilized waste material from said sterilization chamber.
Claim 3
Dependent Claim
30 words
