1 Proekologiczna instalacja pilotażowa do produkcji emulsji asfaltowych modyfikowanych nanostrukturami z polimerów odpadowych nnovative technology manufacturing double-modified asphalt emulsion ang her impact on the achievement of positive environmental effects 1st International Debate: Slovakia Liptovský Mikuláš - 13 January 2017 Grzegorz Nieradka Deputy Technical Project Coordinator

2 PRESENTATION AGENDA Plastic waste market in Poland and in the world Legal aspects of collecting plastic waste Recycling polymeric materials Polymers currently used for modifying bitumen Selected technological issues of liquefaction, purification and modification of polymer waste centre Preface

3 PLASTICS MARKET IN POLAND AND IN THE WORLD Global plastics production Comparing the volume of produced plastics with classic materials

4 WASTE POLYMER MARKET IN POLAND AND IN THE WORLD Most common sources of polymer waste in Poland Consumption of plastics in Poland in 2013 based on application

5 POLYMER WASTE MANAGEMENT IN POLAND AND EU Total: 1,410,000 tons Plastic waste management in Poland and Europe (2010)

6 LEGAL ASPECTS OF COLLECTING PLASTIC WASTE

7 POLYMER WASTE MANAGEMENT storage of waste held in specially adapted for this purpose landfills coking plastic waste burning plastics in waste incineration plants re-use of waste plastics

8 METHOD OF RECYCLING POLYMER WASTE MATERIAL RECYCLING * * * Recovery of high-quality polymer fractions from waste suitable for re-processing Resulting product: recyclate, regranulate, regenerate Universality of the use of recyclate material in the automotive industry

9 METHOD OF RECYCLING WASTE POLYMERS * * FEEDSTOCK RECYCLING Chemical degradation of polymer to a fraction of lower molecular weights or monomers Used due to high price of monomer (condensation polymers, e.g. PET) * Hydrolysis, alcoholysis, acidolysis, aminolysis * Waste segregation and identification

10 WASTE POLYMERS RECYCLING METHOD ENERGY (THERMAL) RECYCLING

11 POLYMERS IN ASPHALT MODIFICATION Styrenic thermoplastic elastomers: SBS (styrenebutadiene-styrene), SEBS (styrene-ethylene-butadienestyrene), SIS (styrene-isoprene-styrene) * Very good dielectric properties * Annual consumption of 1.2 million tons * Resistance to acids and alkalis * Produced in a wide range of hardness

12 POLYMERS IN ASPHALT MODIFICATION SBS (styrene-butadiene-styrene) Consumption at 75% of overall consumption of SBS-SEBS-SIS Mechanical properties of rubber while maintaining processing properties of thermoplastics Rubber substitute, road bitumen and roofing bitumen modifiers exposed to extreme weather conditions

13 SCHEMATIC DIAGRAM OF THE PILOT INSTALLATION

14 Selected technological issues of liquefaction, purification and modification of waste polymer centre Proper selection of feedstock: - polymer softening temperature (liquidation) - purity of raw material (purification) - changing properties (modification). Meeting technological parameters of equipment belonging to the centre Result: nanomodified polymer Other (discussion)
