Scrap Tires (ST) represent a major challenge for their effective management. For tires, that reached the end of their lifespan, gasification represents the energy recycling alternative with major added-value and minimum emissions.

ST gasification produces a synthetic gas, which may be used to produce electricity based on a special system in internal combustion engines with highly efficient outputs and emissions free of toxins and furans.

The synthetic gas – a mixture of hydrogen, carbon monoxyde, methane and propane with a high energy value – is generated during gasification using ST as feedstock, thus replacing fossil fuels and contributing to reduced CO2 emissions. The use of synthetic gas in gas engines improves waste management, imultaneously achieving maximum use of an economic supply of energy.

 

The waste input to the gasification plant must be classified as material with a low-medium calorific value; water content less than 40%; inert material content less than 20%.

The obtained synthetic gas, free of particles, Tar, and other components, is cooled until approx. 30ºC prior to its entry into the Otto cycle motor-generators. These are engines especially designed to operate with lean gases and high methane levels which can achieve electrical outputs above 37%.

 

Since it is a thermodynamic process, gasification is a very reliable process.
