Characteristics

Flexibility of acceptance (chips, entire tyres, truck tyres, car tires, motor cycles tyres etc.)

Flexibility by storage of produced energy as oil (near Diesel (gasoil) quality)

No interference between energy production and pyrolysis process

No atmospheric emissions from the pyrolysis process (vacuum operation)

Emissions to atmosphere from the combustion of the produced oil and gasonly, i.e. similar to combustion of light oil

Batch wise pyrolysis with reloading every 20 min (per reactor), operation atvacuum

Completely automated process control

Innovative and patented process

Industrial plant (60’000tpy) running with truck, car and motor cycle tyres

• SEMI COKE:– Fine semi coke– Suitable for lower quality tires– Very suitable as reducing agent in EAF plants

• Steel– High quality– Recyclable for tire steel or other high steel quality

• Oil– Different energy uses

Use of by-products from the Pyropneu plant

3 possible solutions

Base Solution : production of oil combustion of pyrolysis gas and of process water, semi coke, steel and oil for sale

Option 1 : Base solution with combustion of oil and pyrolysis gas for the production of steam at 15 bar (or otherpressure), semi coke, steel for sale

Option 2: : Base solution with cogeneration using large Diesel engine and recovery of waste heat steam (9,5 T/h),power (8 MWe), semi coke for sale

EconomicsEconomics

• Very favourable ROI possible depending on sales price of steam / el. Power, gate fee of tyres, sales price of by products

• Typical in Europe including green certificate for power sales: 40-45%

• Typical without any subsidies in Europe: 15-18%
