1 Treatment and valorisation of Scrap Vehicle Tyres The CTU-Pyropneu TM Process CTU Clean Technology Universe AG Your Partner for responsible waste treatment

2 Contents Introduction Background Process Overview Characteristics Products Use of Products References Economics Page 2

3 Treatment and valorisation of used Vehicle Tyres CTU-Pyropneu Process Quantity of treated tyres Car and Truck Tyres T/y 21 % Steel - tissue T/y 79 % rubber T/y Granulate - size mm Recycling Pyropneu Process Page 3

4 Process stages Silo P-14 Cold oil Recirculation Washing liquid (water + caustic) Cleaned gas Pyro gas Vacuum pump Liquid ring (oil) vapeur Pyro Gas scrubber Aux. burner Flare systen with desulfurization Pyrolyser 1 Gasoil Steel separator (magnet)l Semi coke + steelr Cooler granulator Coke Cooler Entire tires or chips 100x100 mm Filter press Granulates 15x15 mm max Pyrolyser 2 Semi-coke + steel Gasoil storage Coke cooler Diesel Engine/ Generator set Sale of electrical power Conveyer with magnetic separator Semi-coke Hot water Steel Cooling Tower Cooled water Page 4

5 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 gas only, i.e. similar to combustion of light oil Batch wise pyrolysis with reloading every 20 min (per reactor), operation at vacuum Completely automated process control Innovative and patented process Industrial plant (60 000tpy) running with truck, car and motor cycle tyres Page 5

6 Products from the Pyropneu plant Rubber T/y Granulates - size 5 mm Semi-coke : 38 % Water 3% Pyrolysis Gas 5% Pyrolysis oil: 54 % Reuse Evaporation Production of steam and/or power 24 T/h steam 15 bar 9 T/h steam 6 bars and 8 MWe Page 6

7 Use of by-products from the Pyropneu plant 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 Page 7

8 Use of Products - Energy option 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 : Option 2: : Base solution with combustion of oil and pyrolysis gas for the production of steam at 15 bar (or other pressure), semi coke, steel for sale 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 Page 8

15 Economics 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% Page 15
