Sustainable commercialization of Baru in the Cerrado: mapping its Value Chain for rural livelihood enhancement

Land-use transformation and insufficiently protected areas have led to extensive deforestation and conversion of native vegetation for croplands and pastures in the Cerrado, Brazil’s second-largest ecosystem and one of the world’s biggest biodiversity hotspots. The sustainable harvesting and commercialization of non-timber forest products (NTFPs) offer a potential alternative, contributing to sustainable development by enhancing rural livelihoods, promoting environmental conservation, fostering economic diversification, empowering vulnerable socio-economic groups, and encouraging sustainable resource management. Among Cerrado's promising NTFPs is the Baru nut (Dipteryx alata), a nutrient-dense product rich in protein, fiber, zinc, and healthy oils, with potential therapeutic applications for various health issues. Its unique composition and versatility present an opportunity for sustainable commercialization that enhances rural livelihoods while promoting health benefits. Incorporating Baru-related products into local, national, and international markets could diversify economic opportunities while maintaining environmentally sustainable practices in both production and commercialization. Despite its potential, research on Baru remains scarce, creating a knowledge gap in the dynamics and challenges of its value chain. This study addresses this gap by employing a mixed-methods approach to evaluate the financial performance of each stage of the Baru value chain and identify existing challenges and market opportunities. Focused on Arinos, Minas Gerais, the research incorporates 29 interviews with local value chain actors, 14 supplementary interviews with institutional stakeholders, and secondary data analysis. The findings reveal a fragmented and predominantly informal value chain at the local level, faced with challenges such as physically intensive work, unreliable demand, power imbalances, low-profit margins, and limited institutional support. This research proposes strategies to foster collaboration, equity, transparency, and sustainable development of Baru’s value chain and contributes to a deeper understanding of this NTFP

Design, Development, and Testing of a Vision-Based Calibration System for Liquid Handling Robot

This thesis presents the development of a vision-based calibration routine for an open-source liquid handling system, addressing the challenge of integrating reliable labware detection into an existing robotic platform with minimal hardware redesign. The study adopts an experimental, prototype-driven approach, evaluating multiple proof-of-concept configurations before selecting a top-mounted camera solution as the most viable. The implemented system employs OpenCV’s ArUco marker detection to locate labware, combined with a closed-loop tracking routine that iteratively aligns the camera’s principal point with the detected tag. Alternative approaches, such as rule-based detection with a side-mounted camera, provided valuable insight into system constraints including lighting sensitivity, and variability of labware. The chosen final setup demonstrated reliable calibration output in the form of labware position and orientation data, stored in .JSON format for integration into higher-level control software. The system proved capable of reliable marker-based calibration under controlled conditions. Furthermore, the results highlight both the strengths of the approach such as modularity and adaptability, and its limitations, particularly possible interference due to glare and relatively high setup time. Future work includes integrating object detection models, multi-camera systems for improved pose estimation, and extending the system towards real-time quality control in laboratory automation

Assessing Sustainability Reporting Obligations and Regulatory Compliance for LINEG: An Analysis of EMAS Alignment with Emerging EU Directives.

This thesis assesses the preparedness of LINEG, a German public water utility, for the Corporate Sustainability Reporting Directive (CSRD). It evaluates the extent to which LINEG’s EMAS-based environmental disclosures align with CSRD/ESRS and where extensions are required to meet comprehensive ESG obligations. The analysis is grounded in Stakeholder Theory and Valente’s Stage Model to connect accountability expectations with organizational sustainability maturity. Methodologically, a qualitative case study and qualitative content analysis are applied to LINEG’s EMAS statements and relevant regulatory texts, using deductive categories derived from CSRD/ESRS and SASB, complemented by inductive coding to capture LINEG-specific themes. Peer utilities are referenced to contextualise findings. Findings show a strong environmental foundation— externally validated data on energy, emissions, water, and biodiversity—indicating partial readiness for ESRS E-standards. However, material gaps remain in social and governance areas (e.g., workforce metrics, affordability and service quality indicators, stakeholder engagement processes, and board-level oversight of sustainability). Applying Valente’s model positions LINEG between Defensive and Isolated stages: largely compliancedriven, with initiatives not yet embedded across strategy and governance. The thesis proposes a roadmap to consolidate environmental disclosures into ESRS structures, conduct a double-materiality assessment, expand S and G indicators, formalise stakeholder engagement, and assign clear governance responsibilities. Limitations arise from a single-case, document-based approach and the evolving German transposition of CSRD, which may adjust timelines and specific requirements once fully enacted

Optimising Heat Loss Reduction and Facilitating the Transition to Biogas in Industrial Applications.

This study has evaluated the heat loss potential and energy consumption at the industrial level. Notably, heat loss on a large scale at the industrial level has been recognized as neither economically nor environmentally sustainable. Moreover, the continued use of fossil fuels (natural gas) has been reviewed as unsustainable due to their adverse effect and limited availability, posing challenges for the present and future. Heat loss is optimized at the continental production site in Villingen-Schwenningen. Heat loss through exhaust fans, which extract heat from inside the building and release it to the environment to maintain the internal temperature, has been analysed. The released heat is lost in the environment. To recover this energy loss, the integration of a plate-to-plate heat exchanger is proposed. This approach recovers the rejected heat to preheat the incoming fresh air supply, replacing the traditional heat coil operated on natural gas. Additionally, the transition of natural gas to biogas has been explored. The district heating twin pipe (DN 80) is considered for the smooth flow of thermal energy. For this project, a financial analysis of return on investment (ROI) for 10 years is conducted, the thermal energy flow rate over 2.1km, and heat loss during the transfer phase are calculated. The results have shown significant importance for the recovered energy by integration of a plate-to-plate heat exchanger; yearly, 1.2 GW of energy can be recovered, reducing the consumption of natural gas and making a complete transition towards biogas, economically and environmentally beneficial

Impact of Artificial Intelligence on Capital Market Efficiency and Investment Behavior: A Comparative Analysis of Investors in Developed and Emerging Markets

This thesis explores the transformative impact of Artificial Intelligence (AI) on capital market efficiency and investor behavior, with a comparative lens on developed and emerging markets. It investigates how AI technologies—such as machine learning, robo-advisors, and algorithmic trading—are reshaping investment strategies, reducing behavioral biases, and influencing market dynamics. The study integrates theoretical frameworks, including the Efficient Market Hypothesis, Behavioral Finance, and the Adaptive Markets Hypothesis, to contextualize AI’s role in modern finance. A mixed-methods approach combines literature review, empirical analysis, and survey data from Germany, India, and Pakistan to assess regional disparities in AI adoption, trust, and effectiveness. Findings reveal that while AI enhances decision-making and market efficiency, its benefits are unevenly distributed due to infrastructural, regulatory, and digital literacy gaps. German investors exhibit higher trust and adoption rates, leading to more efficient and diversified investment behavior, whereas emerging markets face barriers such as limited access and awareness. The thesis concludes with policy recommendations to foster inclusive AI integration and outlines future research directions to bridge the digital divide in global financial system

Application of the Ant Colony Algorithm for solving routing optimization problem in logistics

The potential of direct marketing within the transformation process to sustainable farming in Lower Saxony, Germany

Family farms present the majority of farms worldwide, and their survival is crucial to support the growing world population. Preventing those farms from disappearing is therefore very important. These family farms face many challenges like high investments and high price volatility. Diversification in form of direct marketing can be one way to reduce these risks. Objective was to determine the state of direct marketing usage, faced challenges in a direct marketing system, which role counselling services play in that scenario and how farmers perceive sustainability in general and in context with direct marketing. These objectives were reviewed with a quantitative study conducted by an anonymous online survey. Provided to farmers of Lower Saxony by counselling rings, network “LandTouristik Niedersachsen”, network “Kompetenzzentrum Ökolandbau Niedersachsen” and the Chamber of Agriculture. Direct marketing usage had increased over the last years and did not depend on the way of farming. On farm direct marketing solutions like a farm shop were most popular, most likely because it can be a low-cost solution. Bureaucracy, marketing and economic viability are the major challenges in direct marketing systems and correlate with reasons why direct marketing was not used. These presented a clear work order for government, science and counselling services, and show a high potential in increasing farm sustainability. Counselling services presented to be only used if free options were exploited, which emphasized the importance of high quality counselling offers. Overall, on-farm factors stood in favor for diversification and in combination with the as important stated status of sustainability for farmers, direct marketing most likely holds potential to positively impact the transformation to sustainable farming in Lower Saxony
