Definitions

  • the invention refers to a method for the treatment of infectious risk residues, cytostatic and cytotoxic residues and residues of non-cytostatic drugs and a device for the implementation of said procedure. More particularly, the object of the invention focuses on a common treatment system for infectious waste, cytostatic waste and pharmaceutical waste that achieves sterilization of infectious waste, and inertization of the active cytostatic and non-cytostatic pharmaceutical active ingredients, by a process physicochemical based on advanced oxidation, for which, said procedure contemplates the use of the same equipment that essentially comprises a crushing and grinding unit for the crushing and grinding of waste and an advanced oxidation treatment reactor where it is produced the addition and mixing of different oxidants, according to each type of residue. The resulting solid residue is deposited in a solids deposit and is disposed of as an urban waste after carrying out the corresponding analyzes.
  • the field of application of the present invention is part of the industry sector dedicated to the treatment of waste in general, among others to the treatment of infectious risk residues, cytostatic and cytotoxic residues and pharmaceutical residues.

  • the chemical treatment of the crushed residue in the reactor / mixer specially designed for this use is produced by adding a combination of high-power oxidants in a reaction controlled by physical-chemical parameters. It is an Advanced Oxidation process that achieves total waste sterilization.
  • the treatment process comprises the same steps, with the difference that, after crushing, the residue is subjected to a series of high power oxidants, whose combination of oxidants is different from that used for infectious waste.
  • the residue obtained is a solid with a low degree of humidity, and all the residue is deposited in a solid waste deposit in which it will be transported to the landfill.
  • urban waste after performing the relevant physical-chemical and ecotoxicological analyzes.
  • the treatment process is also the same in the crushing and grinding phase to achieve a final particle size that favors the best chemical attack, by means of the specially designed grinder and a mill that participates or not, depending on the characteristics of the pharmaceutical residue to be treated, with the difference that, in the advanced oxidation phase of the pharmaceutical active ingredients, the addition of high-power oxidants is a different combination than the one used for previous waste.
  • the final waste is a solid residue with a low degree of humidity, which is deposited in a solid deposit to be transferred to the urban waste dump after the completion of the relevant physical-chemical and ecotoxicological analyzes.
