Waste Tyre, Rubber & Plastic Pyrolysis Facility

Project Concept and Objectives

The key objectives of the tyre and rubber waste pyrolysis facility are as follows: To demonstrate the viability – technical, financial, environmental, and social - of a private based and sustainable waste management model that has at its core the disposal of tyre and rubber waste , and which is in support of national policies.

Introduction to pyrolysis

The management of rubber wastes is a great challenge due to the huge quantities of scrap tires and rubber goods added every year. This problem exists all over the world. Land filling and stock piling, have undesirable environmental and public health attributes, and waste material resources. Scrap tires provide breading sites for mosquitoes, which can spread diseases. Large tire piles often constitute fire hazards, creating acid smoke and leaving behind a hazardous oily residue. Rubber waste is not biodegradable and was turned to thermosetting on vulcanization due to the presence of the so-called vulcanizing system in rubber mixes. Consequently, it is difficult to recycle rubber waste or reuse it using the general methods used for thermoplastic materials.  Resource recovery of tire and rubber waste is very important since we can recover both materials.  The present work represents new trends for utilization of rubber wastes.

A low percentage of scrap tires are recycled with material recovery and reused for second-quality rubber. The problem is that waste tire generation rate is much more important than the amount of material required for these alternative uses. Because of their high calorific value, waste tires have been used as fuel in rotary cement kilns. However, this process can be acceptable from an environmental point of view only in the case of controlled combustion due to the toxic emissions produced during the tire combustion processes.  The high volatile carbon content and heating value (33-35 MJ/kg) make the scrap tires an excellent material for energy recovery. For this reason, both pyrolysis and combustion are currently receiving renewed attention. Pyrolysis offers an environmentally attractive method to decompose a wide range of wastes, including waste tires. In the pyrolysis process, the organic volatile matter of tires is decomposed to low molecular weight products, liquids or gases, which can be used as fuels or chemicals source. The non-volatile carbon black and the inorganic components remain as solid residues and can be recycled in other applications. Combustion of tires has been used also for generation of electrical energy. However, for minimizing emissions the conditions of the combustion process must be optimized.
