Leading international experts will share their first-class knowledge during two IWWG Training Courses scheduled on Monday 30th September.
Courses are open to all Symposium participants and are suited to beginners.
MONITORING OF LANDFILL GAS EMISSIONS | Sept. 30th, 15:30 - 17:10
Viktoria Wechselberger & Marion Huber-Humer, Institute of Waste Management, University of Natural Resources and Life Sciences, Vienna (AT)
Dipl.-Ing. Viktoria Wechselberger is a research associate at the Institute of Waste Management (University of Natural Resources and Life Sciences, Vienna) focusing on the quantification of methane emissions from biogas plants. Previously, she has worked in R&D in the field of steam explosion pretreatment of ligneous agricultural residues for the production of biogas. She has studied Environment and Bioresources Management with a specialisation in soil research.
Marion Huber-Humer is full Professor for “Global Waste Management” and head of the Institute of Waste Management (University of Natural Resources and Life Sciences, Vienna) in Vienna. Her educational background is in Landscape Planning and Environmental Engineering. She is co-leader of the IWWG task group CLEAR (Consortium for Landfill Emission Abatement Research) for more than 15 years now and MB-member of IWWG. Her research fields include sustainable landfilling, landfill technologies, gas emission monitoring and abatement, with a particular research focus on biological methane oxidation in biocover systems and in-situ aeration, biological waste processing, waste characterization, and waste treatment strategies for innovative materials containing engineered nanoparticles (nano-waste).
On a global level, methane emissions from landfills still represent the largest direct source of greenhouse gas emissions from the solid waste sector. Diverse technologies that should mitigate LFG emissions, like gas extraction systems, methane oxidation covers or in-situ aeration measures, are therefore implemented. For a reliable assessment of the performance of these measures, and particularly for GHG counting and inventories, methods are required, that can cope with the high spatial and temporal variability of landfill gas emission fluxes. In the trainings course current approaches to monitor and quantify methane emissions from landfill sites will be presented. A particular focus will be set on the one hand on conventional methods like chamber systems, and on the other hand on innovative approaches, such as using the open-path tunable diode laser absorption spectrometry (OP-TDLAS). This is a method to determine path-integrated gas concentrations. Based on the measured concentrations as well as meteorological data emissions from the site can be quantified via inverse dispersion modelling. The training course will be run in an interactive manner, with lots of opportunity for questions and discussion, and for specific aspects of particular interest to delegates to be covered.
LEACHATE TREATMENT | Sept. 30th, 18:00 - 19:40
Howard Robinson, Phoenix Engineering (UK)
Howard Robinson is Process Director of Phoenix Engineering and has nearly 30 years of specialised experience in landfill science, especially in the fields of landfill leachate characterisation and treatment. He has worked full-time in the science and practice of leachate characterisation and treatment since 1975, during which time he has written most of the UK’s guidance on leachate management, designed well over 100 full-scale leachate treatment systems, and worked on every continent except Antarctica. He remains hopeful, and keeps a suitcase of warm clothing ready.
At both operational and closed landfill sites in every country, the management of leachate remains a key issue in order to prevent adverse environmental impacts. In addition, management of leachates is the most important factor that will determine the aftercare period for closed landfills; while the majority of landfill gas generation will be completed within about 50 years, the flushing out of soluble contaminants released during wastes decomposition as leachate, will take many centuries. This training course will provide a brief introduction to processes of waste decomposition and leachate generation and composition, but will then focus on state-of-the-art leachate treatment processes, based on detailed operational data from many full-scale leachate treatment plants, in temperate and tropical climates, and in developed and developing countries. Case studies from some of the largest and most advanced leachate treatment plants in the world will be presented and discussed, with plenty of opportunity for delegates to discuss their own leachate problems, and try to find ways in which they can select appropriate technologies, or improve operation of existing treatment systems.
