Resumo
The enormous amount of solids residues and related cost for a suitable disposal
have increased in megacities as São Paulo and Buenos Aires. Inovative technologies may
be used in order to face managing progams with inovative techniques for for recycling or
recover of materials. Gamma radiation was applied in laboratory scale for two different
types of residues: fungi control in vehicular air filters, and for rat bedding waste (RBW)
disinfection. Both materials may be used after irradiation and the radiation doses required
will be discussed. Part of experiments carried out in Argentina evidenced the suitable use
of vermicomposting for growing Calendula officinalis. Radiation doses from 10 kGy up to
30 kGy were tested for controlling microorganisms during the projects and were very
effective. For filters disinfection experiments, DNA sequencing analysis for the fungi that
survived after irradiation not only confirmed the presence of Penicillium, Fusarium and
Aspergillus (toxigenic), fungi but also improved the data: the contamination included
Aspergillus niger, Aspergillus flavus, Penicillium glabrum specie complex and Fusarium incarnatum-equiseti specie complex.
