The composition of the reinforcing fibre obtained from the recycling of scrap tyres was analyzed with a view to finding the most suitable applications for it. The material (RF) was separated into two different parts i.e. fibre (F) and microfibre (MF) to ensure the maximum homogeneity of the material under study. Thermogravimetric analysis (TG) together with differential scanning calorimetry (DSC) and infrared spectroscopy (FTIR) were used to identify the polymers present in the waste and to determine in what proportions they were present. Determination of the temperatures of maximum volatile matter evolution (Tmax), the yield at the end of the pyrolysis and the melting temperatures yielded very useful results for the identification of the polymers. In order to confirm the results obtained, pyrolysis of the pure polymers was carried out and the decomposition products were analysed. The results were then compared with the oil composition data derived from the pyrolysis of the waste fibres. Our results showed the presence of two polyamides, rayon, polyester and aramid.

“…14 Table-1 showed that all the exponent values (n) of the activated carbons were in the ranges of 1.8-1.9 which indicated the heterogeneous activated carbon with wide range of micropores. Figure -5 showed the FT-IR spectra of EFB activated carbon which was observed at wavenumber in the range of 4000-400 nm.…”

Empty fruit bunch of oil palm was used as an alternative raw material for preparation of highly microporous activated carbon. Activated carbon was prepared by impregnation of raw material using 65% of potassium hydroxide and carbonized at different activation temperatures. The nitrogen adsorption-desorption isotherms at 77 K exhibited the Type I at lower temperatures relating to the microporous structure. However, the nitrogen isotherm at 800 o C showed Type IV with high hysteresis loop clearly showing the forming the mesopore. The Langmuir surface area increased with increasing activation temperature which the highest surface area was 1197 m 2 g -1 . Surface chemistry of the activated carbon showed high oxygen surface, functional groups. Morphology structure of activated carbon was clearly exhibited highly porous activated carbon.

“…In some power plants, carbon black is made into slurry and used as fuels. As adsorbent, tyre derived carbon black is very effective in eliminating pollutants such as chromium, lead, copper, dyes and phenol from industrial liquid effluents [17,40,[68][69][70][71]. It is also used to capture industrial gaseous effluents such as SO 2 [24,72].…”

Abstract−Waste tyres have become a grave concern as their accumulation is aggregating every year. Not only the size of waste tyre has to be reduced, but also some useful energy has to be recovered out of it as the world badly requires energy from alternate sources. Pyrolysis is one such method to extract energy potential products from waste tyres. It is extensively used to generate carbon black (solid product), tyre-oil (liquid product) and syngas (gas product) from waste tyres. In that connection, this article discusses the effect of various parameters on the product composition of pyrolysis of waste tyres. The current usage of pyrolysis products and their typical characteristics are also discussed in this critique. Of late, extraction of high value added products, such as activated carbon from carbon black, and limonene from tyre-oil is gaining attention. The article also throws some light on the application and generation routes of activated carbon and limonene from waste tyres.
