Effects of biochar application on anaerobic digestion processes
(2024)
The use of biochar as an additive in anaerobic digestion (AD) is a potential pathway to enhance AD while promoting biomass-to-biochar value chain within a circular bioeconomy. Biochar, a novel biomaterial, serves for managing residual biomass following the cascading use principle, prioritizing material use over sole energy generation. AD, as a well-established method for biogas production and organic substance management, plays an important role in the global carbon cycle. Therefore, this thesis investigated the ...

Optimization on the manufacturing process of fried instant corn noodle using response surface methodology
(2023-07-31)
Instant corn noodles can be manufactured using the air drying and frying process. The objective of this study was to determine the optimum process parameters and emulsifier concentration to produce instant corn noodles from 100% corn flour with relatively good quality characteristics using a cooking-forming single screw extruder. This study consisted of two stages, namely the determination of corn noodles with the fastest cooking time using emulsifier concentrations of 0, 0.5, 1, and 1.5% from the weight of corn ...

Trade-off between carbon offset and economic benefit: Potential of cocoa-based agroforestry system implemented in voluntary carbon market
(2023-11-02)
Agroforestry systems (AFS) are a viable option for the mitigation of deforestation. Thus far AFS has been recognized and financed through the Voluntary Carbon Market (VCM) program; however, analysis of the potential carbon credit payment and productivity trade-off has rarely been conducted. This study aims to analyse the potential of cocoa-based AFS in terms of the trade-off of carbon accumulation and productivity in West Sumatra, Indonesia. The trade-off is shown through 20 years of financial analysis between the ...

Effect of management strategies on the performance of ruminant livestock production systems and the safety of plant and animal products in the city of Sikasso, Mali
(kassel university press, 2012-05-02)
The regional population growth in West Africa, and especially its urban centers, will bring about new and critical challenges for urban development policy, especially in terms of ensuring food security and providing employment for the growing population. (Peri-) urban livestock and vegetable production systems, which can contribute significantly to these endeavours, are limited by various constraints, amongst them limited access to expensive production factors and their (in)efficient use. To achieve sustainable ...

Influence of quebracho tannin extract and activated charcoal on nutrient intake and digestibility, digesta passage, nitrogen balance, and quality of faecal excreta in goats
(kassel university press, 2015)
The current study investigated the possibilities of producing manure that meets the specific requirements of irrigated organic cropping systems under arid sub-tropical conditions.
Therefore, two trials with goats were conducted that investigated the impact of control diets on their digestibility and faecal concentration with the goal to lowerfaecal concentration levels and meet the requirements of irrigated organic cropping.
Feeding ruminants with condensed tannins (CT) will lower ruminal protein degradation, ...

Entwicklung und Erprobung einer kognitiv-sensorischen Methodik für die Erhöhung der Reliabilität von erhobenen Daten in Bezug auf Nachhaltigkeit und Konsumentenverhalten in Deutschland und in der Ukraine
(2023)
Die menschlichen Sinne werden als Brücke zwischen der Mitwelt und dem menschlichen Körper sowie als entscheidender Faktor bei der Bildung von Ernährungserfahrungen beginnend schon im Mutterleib betrachtet. Diese Studie zielt darauf ab, wissenschaftlich zu untersuchen, wie der Wandel hin zu einer nachhaltigen Ernährung unterstützt werden kann, indem das Konsumentenverhalten sowie deren Flexibilität und Änderungsbereitschaft mithilfe einer neuen kognitiv-sensorischen Methode bewertet und bemessen wird.

Lignocellulosic biorefinery with a thermo-biological pretreatment concept
(2023)
There is great interest, not only in technologically advanced societies, in developing innovative sources of raw materials, especially lignocellulosic biomasses such as cereal straw, which do not interfere with food production. In Germany, 4 – 9 million tons of cereal straw, mainly wheat, are utilized annually, corresponding to an energy potential of 57 – 129 PJ/a. Lignocellulose, found in plant cell walls, consists of hemicellulose, cellulose, and lignin, and it requires complex fractionation to enable its polymers ...
