WASTE TYRE PYROLYSIS

The waste tyre pyrolysis division led by Advanced Pyrotech Sdn. Bhd. (“PyroTech”) offers a solution to the treatment of the accumulating waste tyre stockpiles, and thus, giving an exit to the environmental issues arising from the waste tyre stockpiles, via its patented technology – Continuous Process Pyrolysis Technology. The technology converts waste (tyres) into valuable commodities, such as recovered oil, carbon black, non-condensable flammable gas and steel wire.

WASTE TYRE STOCKPILES

Disposal of waste tyres is a major global problem and one which is set to grow unless alternative outlets or methods are developed. Apart from the costs to the community and local governments through littering the landscapes and taking up scarce landfill space, waste tyres are a source of health and environmental concerns: fires in stockpiles can release toxic gases whilst tyre stockpiles provide breeding habitats for mosquitoes. Disposal at landfills without any form of environmental friendly recovery or recycling is also an economic loss as waste tyres are a potentially valuable resource with various re-use, recycling and waste to energy options.

Many countries currently allow the use of tyre-derived fuel (“TDF”) for cement factories, green houses and in power plants as a cheaper substitute to fossil fuels normally burned for such purposes. However, the method is not well received for two reasons: (1) concern about environmentally adverse emissions; and (2) the loss of a resource. Although using TDF reclaims some of the energy that went into making a tyre, it remains the second most wasteful waste tyres management options, just above dumping them.

Many people are engaged in illegal open burning of waste tyres to extract steel wires and this is more rampant especially during the high steel prices period. Open burning often results in incomplete combustion and such practices can release hazardous gases into the open environment, and not to mention the risk of forest fire.

Illegal stockpiles are generally generated by rogue tyre operators taking advantage of unlicensed isolated locations where waste tyres can be dumped. The environmental risks due to controlled or illegal land filling are associated with the breeding of insects, such as mosquitoes, which are capable of transmitting diseases, such as Dengue Hemorrhagic Fever, to humans. In addition, as tyres are not easily decomposed and the structure of the tyre is such that gases are easily entrapped, this would pose severe explosion and fire risk. However, many landfills now are banning the disposal of tyres due to the space it occupies and also for the other reasons stated above.
