Description
Summary:Currently, more than 12 million units of PET bottles are produced in Brazil per day. The post-consumer PET bottles correspond to about 1.0% of the production of urban solid wastes. In this work, the recovery of PET bottles as raw material to produce nanomaterials is studied. Samples of post-consumer PET bottles were inserted in an electric furnace with temperatures of 600 and 1000°C under an atmosphere of 15% O2 and 85% N2. The burned effluent was subjected to a SiC filter and channeled into the second furnace at 1000°C. Stainless steel meshes were placed in the second furnace in order to work as catalyst. Scanner electron microscopy (SEM) technique was used to verify the formation of nanomaterials. Results show the formation of nanomaterials with diameters of 90-140 nm and lengths of about 40 μm. Produced nanomaterials present the tubular form typical of carbon nanotubes.
