Abstract
Disposal of used tyres is becoming an increasingly important environmental issue and the recycling is a more environmentally friendly solution than mass accumulation.A process known as pyrolysis enables the recovery of potential useful products from the rubber portion of used tyre ,such as pyrolytic oil, gas and a carbon black pigment (CBp).Therefore the study was aimed to assess whether the recovered carbon could be used as a pigment in aqueous based inkjet printing inks.The (CBp) contained a higher concentration of inorganic compounds than commercial carbon black, mainly due to the various additives incorporated in the manufacture of the original tyre. The contamination is reflected by the high content of the ash present in the (CBp).A characterization of the recovered carbon black was performed and a possible reduction of the ash content by an acid-base demineralization treatment and physical separation techniques were investigated,thereby improving its quality.In this study we evaluate the properties and performance of the recoverd carbon char as a pigment in water-based ink-jet links.The success of this project could help resolve a major environmental issue and thus be a benefit to us all.The post-pyrolysis car tyre CBp (obtained from coalite ,Debyshire, UK) which was stored under room temperature and pressure and ground to a mean partical size of 20µmThe samples were characterized and evaluated by using different analytical and spectroscopy technique, such as X-ray Flourscence Spectroscopy.
