Description
Summary:The use of the polymeric commodities LDPE and HDPE in the most varied industrial applications and for economic interests, it produces discards in the waste, and great demand of the same ones in the sanitary landfill. In this work we have studied degradation/biodegradation of the polyethylene (PE) in the landfill São Giácomo in Caxias do Sul, Brazil. The PE was collected in cell C4 with 94 months of age and different depths (11 to 16 m). The samples films was analyzed thermogravimetric (TGA), morphologic (SEM) and structural (FT‐IR) determinations of these degraded materials in landfill. The samples in the waste presented the one degradation pick and for the LDPE mass loss it increases and for HDPE mass loss creases with the dump. Evidenced structural changes with absorbency increment corresponding mainly to vibrations in new frequencies. The morphologic analyses (SEM) the films samples they present scales and fissures.
