Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben European Harmonization of Methods to Quantify Methane Emissions from Biogas Plants
In the past years, attempts were undertaken to quantify single emission sources as well as overall emissions from biogas plants using on-site (direct) and remote sensing (indirect) methods. While measurements on site often focus on one type of CH4 sources, remote sensing methods cover the overall emission plume. Among the current available emission measurement techniques, none is in a position to be recognized as the best international reference. Therefore, the establishment of a scientifically based standardization and harmonization of methods would greatly contribute to the assessment of the fugitive emissions from biogas plants.
Agrar- und Umweltwissenschaftliche Fakultät Rostock - Institut für Umweltingenieurwesen - Fachgebiet Abfall- und Stoffstromwirtschaft Mixing in biogas digesters: correlations between laboratory experiments on artificial substrate and simulations with computational fluid dynamicsDr. Fosca Conti, B.Eng. Leonhard Wiedemann, Tomasz Janus, M.Phil. Dipl.-Wirtschaftsing. (FH) Matthias Sonnleitner, Prof. Dr.-Ing. Wilfried Zörner
Energy demand for mixing of biomass digesters is a crucial parameter in design and operation of biogas plants. Optimization of flow characteristics in the fermentation process is usually focused on the stirrers where their placement, shape and number, as well as their rotational speed and switching sequence are all important decision variables for overall energy efficiency planning.

Already at an early stage of biofuels development and production it became obvious, that a potential competition to food and feed production could occur, supported by a number a potential studies and systems analysis. Based on their results a concept was derived for the use of the vast amounts of low grade, residual biomass for use in large scale synthetic biofuels production.
TK Verlag - Fachverlag für Kreislaufwirtschaft Mechanical-Biological Treatment Plant in Hanover, Germany – Experience in Mechanical Processing, Anaerobic Digestion and Refuse Derived Fuel Quality –Dr. Beate Vielhaber
The Hanover mechanical-biological treatment (MBT) plant can look back on 15 years of operator´s experience. The mechanical treatment facility has been working largely without any issues due to the simple technique and the comfortable redundancy and design. The biological treatment facility faces growing damage due to ageing of materials, which is accelerated by microbiological attack, and corrosive and abrasive ingredients in the residual waste. Comprehensive maintenance, renovation and replacement measures are planned.
Agrar- und Umweltwissenschaftliche Fakultät Rostock - Institut für Umweltingenieurwesen - Fachgebiet Abfall- und Stoffstromwirtschaft Fast methanification of swine manure as an example for substrates with low organic contentProf. Dr. Heralt Schöne, Andreas Speetzen
A biogas reactor of 45 mÂ³ was fed with pure swine manure. A straw layer worked as an anaerobic filter on top of the fluid. The manure was continuously circulated to irrigate the straw. Hydraulic retention time (HRT) of straw was 45 days. HRT of manure was reduced from 45 to 7.5 days within one year. Average concentration of volatile solids (VS) of manure only was 1.8 %. We varied VS concentration and temperature to simulate normal disturbances of operation. Gas production normalized within one day after each short heating interruption. Variations of VS concentration had no negative influence on the Operation as a whole. After two months, a zone with granular sludge in autonomous fluidization was observed just below the straw layer. This shows that the reactor is a hybrid biogas reactor containing a fixed bed on the top, and an UASB zone below.
Wasteconsult international Comparison of MBT plants with and without upstream Anaerobic Digestion (AD) in terms of moisture Management and achievement of landfill disposal criteriaAurel Lübke, M.Sc. Roman Lugmayr
In waste industry the trend has developed to treat municipal solid waste (MSW) within an anaerobic digestion process. For this purpose MBT plants with an upstream AD plant were built. In the context of plant monitoring and trials one MBT with AD and one MBT without AD were examined and compared to determine the impact of the AD process. For this, the plant operation, especially the moisture management, the compliance of the landfill criteria and also the economic efficiency of the MBT were investigated.
Wasteconsult international Liquid Digestate-free Anaerobic Digestion with the HZI-KOMPOGAS® plug flow digesterDipl.-Ing.agr. Raiko Kolar
The KOMPOGAS® plug flow fermentation is a highly efficient process for generate energy from waste. The digestate from the fermentation has in this case due to the System to a water content between 70 and 75 percent. Due to its high content of nutrient salts press water can generally be used without further purification as liquid manure in agriculture. In many regions or even countries, there is due to intensive livestock farming, already a large oversupply of liquid manures or spreading is not allowed by law. Also the logistic could be difficult and expensive.
Wasteconsult international The APECS-biomass modelDr. Jan Mumme
Organic wastes in all their different shapes and compositions have gained significant commercial, political and academic interest during the last decade. The main driver for this development is the widely accepted consideration of organic wastes as valuable resources rather than problematic or worthless stuff. With the aim to turn the economy from its fossil basis into a bio-economy with presumably higher resource efficiency and less negative or even positive climate impact, governments in many countries have startedto support the use of waste biomass in many ways including subsidies.
Wasteconsult international Development of a rotating fermentation reactor for Biogas production from organic wasteDipl.-Ing.(FH) Felix Brück
To maximize biogas yields, adequate substrate mixing during anaerobic digestion (AD) is of particular importance. In dry AD this may be hampered by high solid matter Contents causing a pronounced wear of mixing tools and triggering costly maintenance interruptions. This study aims at the development of a rotating drum fermenter (RDF) to overcome these problems. As a first step towards the development of a full-scale RDF for dry AD of biowaste, particular attention was given to the mixing performance. Therefore, a lab-scale RDF was constructed from acrylic glass to allow visual inspection of the radial mixing process.
Wasteconsult international Peripheral fermentation of organic waste – Insights and data from practiceStephan Hinterberger
The fermentation of organic waste is a valuable source for alternative energy and nutrients in form of fertiliser. To increase the treatment of organic waste quantities, peripheral digestion plants can have a significant contribution. Although small scale digestion units have higher Investment costs based on the waste quantities processed, a specialisation on suitable wastes and an efficient use of alternative energy and fertiliser can guarantee an economic and ecological success.
Wasteconsult international Compost-like material or thermal valorization – impact on MBT Plant economics and environmental aspects – Case studies in Portugal and UKDipl. Ing. Stephan H. Schulte, João Rita, Joel Braga, Chris Mannall, Dipl. Ing. Hans Kübler
The paper focuses on the utilisation of the solid product from the biological Treatment stages of three MBT Plants which treat the organic fraction of MSW by means of wet mechanical pre-treatment units followed by anaerobic digestion. The experiences of two MBT Plants in Portugal (CVO Valorlis and CVO Suldouro) which produce compost-like material are contrasted with the experiences at the MBT Bredbury Parkway (UK) which, by drying the digested solids, produces a RDF with low calorific value for further use in thermal valorisation. The impact of these two different approaches on the operating costs for the treatment of the digested solids as well as the environmental aspects for both valorization paths is discussed.
Wasteconsult international Operation experiences at the MBT Maresme, the latest wet anaerobic digestion plant for MSW built in SpainMartin Ernst, Ottokarl Muck, Dipl. Ing. Stephan H. Schulte, Jacobo Moreno Lampaya
The MBT Maresme is the latest wet anaerobic digestion plant for the Organic Fraction from Municipal Solid Waste (MOR -Materia Orgánica Residual), that has been built in Spain, in countercurrent to the observed development towards MBT plants with only composting technology. In the present paper a short presentation of the MBT Maresme is given before the operation experiences during the start-up phase and the guarantee tests are discussed. Despite the challenge the operation of this facility under aggravating circumstances implied, the achieved performance and clearly advantageous energetic balance confirm the integration of a digestion step in MBT plants as a valid and valuable concept.
