ABSTRACT:
A reactor/sterilizer for disinfecting contaminated medical and/or biological waste comprises, in accordance with the present invention, at least one shredder/grinder to reduce in size solid waste to be disinfected, means to introduce waste into the shredder/grinder, a freezer or ice maker which traps disinfecting concentrations of ozone from an ozone generator in ice so that the ice can be added to the bio-medical waste prior to a shredding or grinding step. In a disinfecting method, the present invention relates to the treatment of biological and/or medical waste with ozone containing ice by admixing the ice with the the waste and allowing the ice to melt, thereby releasing ozone and exposing the waste to effective concentrations of ozone to disinfect the waste. In preferred embodiments, the instant biomedical reactor/sterilizer has both a coarse shredder/grinder and a fine shredder/grinder. The shredder/grinder produces a slush or slurry of waste and ice-containing ozone. As the temperature of the slurry increases, the entrapped ozone is released in a sustained manner as the ice melts over time and mixes with and disinfects the waste.
