Learning objectives

The course impart advanced aspects how to manage and treat waste in the sense of sustainability. At the beginning, waste and the responsibilities for waste will be defined and the general conditions as well as the specific waste amounts will be discussed. Then waste management techniques and processes like collection, transportation, sorting, treatment, recycling and disposal are shown. With regard to process engineering, concepts and techniques for mechanical and biological treatment (composting, digestion), their combination (MBT, MBSt) and techniques for thermal treatment (wte, combustion, gasification, etc.) are presented. With respect to EU´s waste hierarchy, concepts and techniques will be exposed in particular and related to each other for avoiding, recycling and reuse and for the disposal of the waste treatment output. Process descriptions, design data and conditions as well as output qualities are debated according to legal criteria for disposal, emission or environment protection. Furthermore, principles and requirements of landfill´s construction, their control and emissions plus the handling of abandoned polluted areas are taught. Modern recycling techniques for glass, paper, plastics, wood, metal and construction waste are also part of this course as the evaluation (e.g. ecobalancing) and elaboration of administrative waste management concepts. The lecture focuses on contemporary practical examples and the knowledge will be consolidated in tutorials in form of calculation examples. After successful completion of the module the students are able to

- identify crucial impacts on waste quality, waste collection measures and waste production;

- elucidate waste management techniques and recycling processes;

- represent the legal criteria and requirements for waste management and disposal;

- develope treatment concepts for different kind of wastes and recycling materials;

- estimate treatment options for polluted areas;

- design a composting plant and concept a landfill with respect to leachate and gas production;

- discuss waste management issues within the legal framework of climate change and environment protection.
