So the use of secondary raw materials gains is important due to economic and ecological reasons. Non Ferrous-, precious- and rare earth metals were detected in household waste (Municipal solid waste, MSW) for years. In MSW-treatments plants NF-metals are actually mostly separated from dried fractions. The separation of these metals is carried out with the aim of removing particles which disrupt further processing. A selective enrichment of individual non-ferrous metals has not been carried out previously. The separated fractions contain mixtures of Al, Cu, Zn, Pb, Sn, alloys, precious metals (e. g. Au, Ag, Pt) and rare metals (Ga, In, Nd etc.) along with considerable amounts of contaminations. The R\&D project "NE-Rec" selectively processes the coarsely separated non-ferrous-metal-conglomerates increasing the concentration of targeted metals. Metals and metal mixtures are concentrated by sorting steps and the impurities are discharged from the process. Still contaminated precious metals are then subjected to a wet-chemical treatment. So metals can be specifically brought into solution or can be precipitated to separate unwanted components (inerts, polymers, foreign metals). Further the relevant metals will be concentrated by thermal-metallurgical processes. The technology, developed in the R\&D project, enables identification, separation and processing of non-ferrous metals, precious metals and REM in household waste and transfers them into further processable individual fractions.}, language = {en} } @inproceedings{NarraBrinkerAy, author = {Narra, Satyanarayana and Brinker, Mona and Ay, Peter}, title = {Particle size distribution of communited and liberated cereal straws measured with different image analysis systems and their characteristic influence on mechanical pellets quality}, series = {XXVI International Mineral Processing Congress - IMPC 2012 : New Delhi, India, September 24 - 28, 2012}, booktitle = {XXVI International Mineral Processing Congress - IMPC 2012 : New Delhi, India, September 24 - 28, 2012}, publisher = {New Delhi}, isbn = {81-901714-3-7}, language = {en} } @inproceedings{NarraDasguptaAyetal., author = {Narra, Satyanarayana and Dasgupta, Sunanda and Ay, Peter and Zeng, T. and Weller, N.}, title = {Pelletisation of Rye- and Wheat straw with additives}, series = {19th European Biomass Conference and Exhibition, proceedings, ICC Berlin International Congress Center Berlin, Germany, conference 6 - 10 June 2011}, booktitle = {19th European Biomass Conference and Exhibition, proceedings, ICC Berlin International Congress Center Berlin, Germany, conference 6 - 10 June 2011}, publisher = {ETA-Florence Renewable Energies}, address = {Florence}, isbn = {978-88-89407-55-7}, language = {en} } @inproceedings{NarraGlaserAy, author = {Narra, Satyanarayana and Glaser, Claudia and Ay, Peter}, title = {Abrasion and strength of biomass pellets as main mechanical stability characteristics}, series = {19th European Biomass Conference and Exhibition, proceedings, ICC Berlin International Congress Center Berlin, Germany, conference 6 - 10 June 2011}, booktitle = {19th European Biomass Conference and Exhibition, proceedings, ICC Berlin International Congress Center Berlin, Germany, conference 6 - 10 June 2011}, publisher = {ETA-Florence Renewable Energies}, address = {Florence}, isbn = {978-88-89407-55-7}, language = {en} } @inproceedings{KarthikeyanAyNarra, author = {Karthikeyan, J. and Ay, Peter and Narra, Satyanarayana}, title = {Energy Production from Agricultural residues and Crop processing Wastes: Some Problems and Perspectives}, series = {International Conference on Green Power Generation: Vision 2020}, booktitle = {International Conference on Green Power Generation: Vision 2020}, doi = {10.13140/2.1.3330.8965}, pages = {9}, language = {en} } @inproceedings{NarraGlaserGusoviusetal., author = {Narra, Satyanarayana and Glaser, Claudia and Gusovius, Hans-J{\"o}rg and Ay, Peter}, title = {Comparison of grinding and liberation processes for stalky biomass materials as a prerequisite for production of energy pellets with high calorific value}, series = {XXV International Mineral Processing Congress, IMPC 2010, "Smarter processing for the future", Brisbane, Australia 6-10 September 2010, congress proceedings}, booktitle = {XXV International Mineral Processing Congress, IMPC 2010, "Smarter processing for the future", Brisbane, Australia 6-10 September 2010, congress proceedings}, publisher = {AusIMM}, address = {Carlton South, Australia}, isbn = {978-1-921522-28-4}, language = {en} } @inproceedings{NarraGlaserGusoviusetal., author = {Narra, Satyanarayana and Glaser, Claudia and Gusovius, Hans-J{\"o}rg and Ay, Peter}, title = {Pelletisation of cereal straws as a source of energy after specific communition processes}, series = {18th European Biomass Conference and Exhibition, proceedings of the international conference held in Lyon, France, 3 - 7 May 2010}, booktitle = {18th European Biomass Conference and Exhibition, proceedings of the international conference held in Lyon, France, 3 - 7 May 2010}, publisher = {ETA-Florence Renewable Energies}, address = {Florence}, isbn = {978-88-89407-56-5}, language = {en} } @inproceedings{JurischkaPedaNarraetal., author = {Jurischka, Constantin and Peda, S. and Narra, Satyanarayana and Smieszek, Marlene and Stollberg, Christian and Ay, Peter and Kay, M.}, title = {Innovative technologies for production of highly pure substances and bio fine chemicals from plants}, series = {18th European Biomass Conference and Exhibition, proceedings of the international conference held in Lyon, France, 3 - 7 May 2010}, booktitle = {18th European Biomass Conference and Exhibition, proceedings of the international conference held in Lyon, France, 3 - 7 May 2010}, publisher = {ETA-Florence Renewable Energies}, address = {Florence}, isbn = {978-88-89407-56-5}, language = {en} } @inproceedings{MarkowskiNarraAyetal., author = {Markowski, Jens and Narra, Satyanarayana and Ay, Peter and Pempel, Harry and M{\"u}ller, Mike}, title = {Automatic disassembly and recycling of lithium-traction-accumulators}, series = {Proceedings, XXVII.

Increasing numbers of electric powered cars, electrobikes and E-Scooters define the transport sector. Recently lithium based traction batteries as storage medium have led into matrurity of series production combining high electrical efficiencies with low weights and compact dimensions. Due to the relatively young development with lithium batteries utilization, only few investigation were conducted regarding their recycling. Conventional battery recycling processes can not be applied due to differences in design and chemistry. So an automated disassembly and processing procedure for lithium traction batteries has been developed in the R/D-project "Li-WERT". Instead of complete smelting of the batteries without pretreatment, an automated disassembly and specific treatment of the material streams was realised, adjusted to the needs of the subsequent recovery technologies. A higher quality, with reduced expenses for the separation of fine-grained or fused material mixes, can be obtained for the individual components. The automated disassembly using an industrial robot significantly reduces dangers for the operating crew. The selective disassembly and beneficiation allows full recovery of the fractions. The batteries will be disassembled to cell level by the industrial robot. Anodes, cathodes, and separation layers are isolated and processed. The technology is designed, that no waste is generated for disposal. The pelletised cathode coating and the other separated metals (stainless steel, copper, aluminum) can be used in respective metallurgical plants. Circuit boards and plug contacts are also coveted secondary raw materials for reuse. The process is modular and offers high flexibility, e. g. for new battery types/ sizes by quick adjustment of the robot and tool change. Adaptation to other cathode materials (e. g. Li[FePO]) is possible. After finishing the R/D-project, a pilot plant for demontage was realised in 2013.}, language = {en} } @inproceedings{MarkowskiAyPempeletal., author = {Markowski, Jens and Ay, Peter and Pempel, Harry and M{\"u}ller, Mike}, title = {Entwicklung eines innovativen Verfahrens zur automatisierten Demontage und Auf-bereitung von Lithium-Ionen-Batterien aus Fahrzeugen}, series = {Recycling und Rohstoffe : Band 5}, booktitle = {Recycling und Rohstoffe : Band 5}, edition = {1.

This result in the obligatory need to separate additionally metallic and other components of the automotive shredder residues (ASR), so that they can be professionally prepared for recycling and reuse further. Currently the iron-containing fines of ASR are deposited as it is not possible to process in blast furnaces due to its particle size (< 4 mm), composition and material properties. Additionally problems are also caused in handling and transportation (dust) of the material. This work focuses mainly on the ASR materials utilization in blast furnaces. Material was further separated into two consecutive fractions by carrying out repeated crushing and magnetic separation twice. The two fractions have significantly higher iron content (up to 75 wt.-\%) compared to the initial material mixture. The materials were assessed for their usage in blast furnaces based on the possible pelletisation with and without binders, stability of pellets, shape and size of pellets, etc. Pelletisation of the material was carried out with a single mould pellet press. Further lignite coal was added to the mixture as additive which improved the pelletisation behavior and the mechanical stability of pellets. Lignite coal was chosen as reducing agent in the blast furnace process contributing towards additional savings in energy supplied. The experiments reveal that the production of pellets from iron-containing fines is possible with a lignite coal admixture of about 15 wt.-\%. These pellets displayed good mechanical stability and can be used in blast furnace processes in recovery of the recyclable metals which are currently not recycled. The recycling of not yet recyclable metals would reduce the deposition and can be easily adopted into the economic cycle by their utilization.}, language = {en} } @misc{KochAyPritzkowetal., author = {Koch, Roland and Ay, Peter and Pritzkow, Olaf and Preuß, Volker}, title = {Herstellung und Verwendung von agglomerierten Naturfasern zum Zweck der biochemischen Wasseraufbereitung}, language = {de} } @misc{AyBrandesKochetal., author = {Ay, Peter and Brandes, Verona and Koch, Roland and Walaszek, Wiktoria}, title = {Verfahren und Anordnung zur Herstellung von Pellets aus Eisenhydroxidschl{\"a}mmen sowie deren Verwendung}, language = {de} } @misc{NarraTaoGlaseretal., author = {Narra, Satyanarayana and Tao, Yonggui and Glaser, Claudia and Gusovius, Hans-J{\"o}rg and Ay, Peter}, title = {Increasing the calorific value of Rye straw pellets with biogenous and fossil additives}, series = {Energy and Fuels}, volume = {24}, journal = {Energy and Fuels}, number = {9}, issn = {0887-0624}, pages = {5228 -- 5234}, language = {en} } @techreport{NarraAyMarkowskietal., author = {Narra, Satyanarayana and Ay, Peter and Markowski, Jens and Glaser, Claudia}, title = {Grundlagenuntersuchungen: Innovative Makroverkapselung von G{\"a}rresten}, publisher = {BTU, LS Aufbereitungstechnik}, address = {Cottbus}, pages = {56}, language = {de} } @incollection{NarraLogschGlaseretal., author = {Narra, Satyanarayana and Logsch, Florian and Glaser, Claudia and Ay, Peter and D{\"o}hling, Frank and Leistner, Diana and Strube, Dieter}, title = {LignoBioFuel : Entwicklung eines Verfahrens zur Herstellung von stofflich und energetisch nutzbaren Bioagglomeraten auf der Basis von Lignin}, series = {Effizient, umweltvertr{\"a}glich, dezentral - neue Konzepte f{\"u}r die Nutzung von biogenen Festbrennstoffen, Bd. 2}, booktitle = {Effizient, umweltvertr{\"a}glich, dezentral - neue Konzepte f{\"u}r die Nutzung von biogenen Festbrennstoffen, Bd. 2}, editor = {Thr{\"a}n, Daniela and Pfeiffer, Diana}, publisher = {DBFZ, Dt.
