    • The recycling of vehicle tyres at the end of their life cycle is a universal problem and many processes have been developed to deal with this problem including the process of pyrolysis which involves the thermochemical decomposition of rubber at elevated temperatures. Several problems are believed to hinder the technical and commercial pyrolysis systems most importantly the problems encountered in downstream processes for handling the pyrolysis products as well as the problems encountered with environmental factors. So far no one pyrolysis system is known to be suitable for producing products having industrial i.e. commercial applicability and without producing waste by-products. Thus, although there is extensive literature as well as several patent disclosures relating to systems or processes for decomposing waste vehicle tyres by thermal pyrolysis producing oils and other by-products, none of them refers to the industrial applicability of the Tyre Pyrolysis Oil (TPO) and, in particular, the use of the TPO as fuel for the production of electricity on a commercial scale utilising internal combustion engines within the same premises thereby not having to dispose waste by-product outside the plant boundaries. A number of existing pyrolysis plants throughout the world produce a Tyre Pyrolysis Oil (TPO) which is considered to be a waste by-product and it has to be handled as such. The proposed system, which is the subject of this patent application, is based on the overall concept of putting several unit processes together to produce electrical power, which is the target end product right from the waste tyres within the same premises and therefore avoiding any waste product leaving the premises. The system consists basically of several unit processes which are utilised to achieve three main objectives i.e., a) Producing TPO, Carbon Black (CB) and scrap steel wire products of specific quality standards for eligible industrial uses, b) Upgrading the pyrolysis oil to a quality standard suitable for combustion as fuel in power generating engines of the Internal Combustion Engine (ICE) type producing electrical power as the main target end product on a commercial scale, c) Gaseous emissions with no adverse impacts to the environment thus complying to all environmental laws and regulations applicable anywhere It is also noted that the proposed system does not require any external sources of energy and it is self-sustainable once it has been placed into operation.
