Pełny tekst źródłaThe present thesis deals with the mix development of a cement-reduced eco-concrete for the use in an ecologically improved ceiling system. For this purpose, a physical analysis model built in Microsoft Excel – the Compaction-Interaction Packing Model according to FENNIS – was used to develop recipes which, due to an optimised packing density, have a low cement paste requirement. It was possible to partially replace cement with fine limestone powders and to produce a CO2-saving mixture with a reduced cement content of 150 kg per cubic metre of concrete, which meets the requirements placed on it – among other things with regard to strength (strength class C 20/25), workability (consistency class C3) and alkalinity (pH-value > 10). These properties were tested experimentally. Although only partially realistic values were determined in the model for the prediction of strength and consistency based on empirical data, the model turned out to be a suitable instrument for mix developments of eco-concretes.:1 Einleitung 2 Verringerung der Umwelteinwirkungen bei der Betonherstellung 3 Methodik der Mischungsentwicklung zementreduzierter Ökobetone 4 Packungsdichteberechnung mit dem Compaction-Interaction Packing Model nach FENNIS 5 Mischungsentwicklung eines Ökobetons im Rahmen des Forschungsvorhabens GRO-COCE 6 Herstellung der Auswahlmischungen und experimentelle Ermittlung von Betoneigenschaften 7 Eingrenzung einer Zielmischung 8 Diskussion der Ergebnisse 9 Zusammenfassung und Ausblick

Kết quả cho thấy, khí hóa trấu để sản xuất điện có tiềm năng giảm phát sinh khí CO2 nhiều nhất. Kết quả phân tích chi phí cho thấy việc giảm thiểu chi phí có thể đạt được khi thay thế sử dụng nhiên liệu hóa thạch trong kịch bản dùng trấu cho nấu ăn. Giữa các kịch bản về sản xuất điện, hiệu quả kinh tế cao nhất trong trường hợp đốt trực tiếp trấu để sản xuất điện ở quy mô công xuất lớn (30MW) và khí hóa ở quy mô trung bình (5MW). Trường hợp dùng củi trấu không mang lại hiệu quả kinh tế so với dùng trực tiếp trấu để phát điện. Hai trường hợp dùng trấu để sản xuất dầu sinh học và khí hóa gas công suất lớn (30MW) cho thấy chi phí tăng cao so với điều kiện biên. Kịch bản cho kết quả khả thi về hiệu quả kinh tế và giảm phát thải CO2 là dùng trấu để nấu ăn, đốt trực tiếp để phát điện công suất lớn và khí hóa công suất trung bình.

Pełny tekst źródłaLife cycle assessment (LCA) analyses the environmental performance of products and services and has become increasingly important also for the environmental assessment of dairy systems. In order to create consistent results for communication, declaration and comparison, the International Dairy Federation (IDF) provides a guideline for the calculation of product-related greenhouse gas (GHG) emissions in the dairy sector. However, the effects of farm data variability and emission factor uncertainty on the comparability of GHG assessments on the farming level are seldom considered. This thesis aims to fill this gap. In the first study, different settings in the definition of energy corrected milk (ECM) and the reference flows were compared in a calculation example based on average farming data. A high bandwidth of the carbon footprint result indicated a severe uncertainty when calculation procedures are not well documented. The second case study examined the production data from six consecutive milk years in an organic dairy farm in northern Germany and its effect on the estimation of product-related GHG emissions. It was shown that data from at least four years is needed to provide reliable results for that farm. The third study dealt with the demand of the IDF guidelines to use at least Tier 2 in the methodology of the Intergovernmental Panel on Climate Change (IPCC). Using data from 20 Norwegian dairy farms, the uncertainty of the carbon footprint using Tier 1 of the IPCC guidelines within the FARM model was assessed. From all 190 direct comparisons of two farms in the study, 78 % of the comparisons were significantly different with a relative difference of 8.7 % being enough to establish significance of the difference. From the three studies it was concluded that existing rules may partly not be precise enough to allow for comparison of farms or farming systems, or partly too strict and thereby hindering the execution of carbon footprint studies.

Pełny tekst źródłaHydrolysis and digestibility of cattle waste as feedstock for anaerobic digestion were improved by thermobarical treatment in lab-scale experiments. The effects of this improvement on greenhouse gas emissions, energy balance and economic benefit was assessed in a full-scale model application. Thermobarical treatment temperatures in lab-scale experiments were 140 to 220°C in 20 K steps for a 5-minute duration. Methane yields could be increased by up to 58 % at a treatment temperature of 180°C. At 220°C, the abundance of inhibitors and other non-digestible substances led to lower methane yields than those obtained from untreated material. In an extended analysis, it could be demonstrated that there is a functional correlation between the methane yields after 30 days and the formation rate and methane yield in the acceleration phase. It could be proved in a regression of these correlation values that the optimum treatment temperature is 164°C and that the minimum treatment temperature should be above 115°C. The theoretical application of a full-scale model was used for assessing energy balance and greenhouse gas emissions following an LCA approach according to ISO 14044 (2006) as well as economy. A model device for thermobarical treatment has been suggested for and theoretically integrated in a biogas plant. The assessment considered the replacement of maize silage as feedstock with liquid and / or solid cattle waste. The integration of thermobarical pretreatment is beneficial for raw material with high organic dry matter content that needs pretreatment to be suitable for anaerobic digestion: Solid cattle waste revealed very short payback times, e.g. 9 months for energy, 3 months for greenhouse gases, and 3 years 3 months for economic amortization, whereas, in contrast, liquid cattle waste did not perform positive replacement effects in this analysis.
