The name of network promises quality “made in Bavaria”. • Our network is your advantage • Many years of experience with recycling technology • Technologies of world-wide reputation • Intensive cooperation • Fast and personal implementation • International activities and services abroad

6. The network Support for our members • Innovation: We develop and encourage innovations. • Marketing: We show our paces and offer our special technologies. • Interest- and knowledge management: We transfer our knowledge actively between our members. Thus we are always one step ahead!

7. The network Focus areas • Successful implementation of innovative recycling technologies and their practical application. • Provide of relevant solutions for the increasing industrialization, the worldwide urbanisation and the scarcity of resources. • Response to the increasing global interest in ecological recycling technologies.

9. 66% 83% 80% Current situation Recycling of mass material in Germany

10. Current situation Need for developement • Requirement for further processing or recovery of the materials, also from an economic point of view. • However, the increasing complexity of input flows acts contrary to this. These input flows require highly-effective technologies and intelligently combined procedures. • High demand for increasingly scarce resources • Concurrently rising prices

11. Current situation concrete tasks and objectives Treatment of mass materials: sorting mixed fractions Purifikation: detecting / separating impurities RESOURCES Processing of complex waste streams Recovery of valuable materials

12. Current situation Challenges • There is no standard in recycling processes. • Processes can be designed variously, aggregates can be combined individually. • Both depending on the form of material and the requested preparation.

18. Processes and technologies Size-reduction, disaggregation and shredding • Disassembly of components • The input material is crushed by using a combination of impact and shear forces. • All materials are selectivly reduces in size and composite materials are disintegrated to a large extent • The separation is achieved without destruction of the components 19/11/14

19. Processes and technologies Size-reduction, disaggregation and shredding • Shredding • The material is sized by the hooks of the knives, pulled in and cut between the knives of the two opposed shafts. • The two strong cutting rotors master all materials, even if difficult to shred or large and voluminous. Martens Hans, Recyclingtechnik, Spektrum Akademischer Verlag, Heidelberg 2011

20. Processes and technologies Size-reduction, disaggregation and shredding • Selective size reduction and compaction • Intensive impact and shear effect is achieved between the horseshoe-shaped impellers and the anvil ring. • All composite materials are highly disintegrated and in addition a selective size reduction takes place: • Brittle-hard materials are greatly reduced in size • Metals are shaped to small balls • Elastic materials are torn into smaller pieces

21. Processes and technologies Size-reduction, disaggregation and shredding • Granulating • Rotor and stator are equipped with high quality solid knives. • The material is cleanly sheared off between rotor and stator – a defined granulate is formed by the perforated sieves mounted below the rotor • A precondition for optimal performances and best separation of materials. Martens Hans, Recyclingtechnik, Spektrum Akademischer Verlag, Heidelberg 2011

22. Processes and technologies Separation and classification • Screening • The machine uses its variable sieve formats to sort bulk materials into various particle sizes. • The screening box is made to oscillate diagonally using excenters by a drive system.

23. Processes and technologies Separation and classification • Sensor-supported sorting • Identification of the type of impurity and its position in the material flow • Use of high-frequency detector coils and line-scan cameras, laser technology, X-ray scanners or close-range infra-red spectral analysis. Martens Hans, Recyclingtechnik, Spektrum Akademischer Verlag, Heidelberg 2011 • Contaminants are separated and sorted using various rapid-reacting mechanical or pneumatic devices; reject flaps, pneumatic pushers, extraction systems or air blast units.

24. Processes and technologies Separation and classification • Sifting • The machine sorts various bulk materials according to their specific gravity, their shape and size. • The sorting product is fed into the zigzag channel and distributed through the entire cross-section of the sorting channel. • The sorting air generated by the fan flows through the sorter from the bottom to the top; this causes the material to be flooded by air and separated. Martens Hans, Recyclingtechnik, Spektrum Akademischer Verlag, Heidelberg 2011

25. Processes and technologies Separation and classification • Electrostatic separation • The material is separated into a conductive and a non-conductive fraction • Conductive materials (metals) give up their charge very quickly to the drum and are ejected by the rotating movement. • The non-conductive materials however loose their charge very slowly, remain adhered to the surface of the metal drum and are finally brushed off. Martens Hans, Recyclingtechnik, Spektrum Akademischer Verlag, Heidelberg 2011

26. Processes and technologies Conditioning and processing • Mixing, drying, sterilization, vaporization • The machines work turbulently, i.e. in a mechanically produced fluidized bed or alternatively in an aggregate • The process is superbly suited for gentle product homogenization, for the preparation of solid mixtures, solid-liquid mixtures and pastes.

27. Processes and technologies Conditioning and processing • Treatment of organic waste • Production of biogas that is used to generate electricity and heat. • The digestate that remains in the digesters can be used as liquid fertilizer. • Alternatively, it can undergo a solid-liquid separation, whereas the solids are a marketable compost after composting.

28. Processes and technologies Conditioning and processing • Briquetting • Making briquettes from production residues creates valuable products for the generation of heat and secondary raw materials • Recovery of operating media • Reduced costs on handling and transport
