Towards Fine-Grained Sensor-Based Probabilistic Individual Air Pollution Exposure Prediction using Wind Information
The estimation of pollutant exposure is highly dependent on the spatial and temporal resolution of the underlying model. This work presents a street-level Gaussian Process Regression model for urban air quality that uses a novel covariance kernel based on physical considerations to process wind information. This model can be driven by information from observations from low-cost sensor networks. We present the model, including the construction of the wind angle kernel, and discuss the inconclusive evaluation to date, the current challenges, and the way forward.
everWeather: A Low-Cost and Self-Powered AIoT Weather Forecasting Station for Remote Areas
Weather constitutes a crucial factor that impacts many of the human outdoor activities, whether they are related to obligations or pleasure. In the contemporary era, due to climate change, the weather is more unstable and the forecasting task is more challenging than ever. By combining the Internet of Things (IoT) with Artificial Intelligence (AI), a new research field emerges that is called Artificial Intelligence of Things (AIoT) and could offer significant possibilities for the research community in order to efficiently tackle the short-term weather forecasting. Renewable energy sources constitute solutions for the achievement of sustainability development goals and could also offer power autonomy in a weather forecasting station. In the present research study, everWeather is proposed as a low-cost, self-powered weather forecasting station based on the AIoT paradigm and renewable energy. The proposed solution combines a variety of low-cost environmental sensors, the prowess of solar energy and an appropriate lightweight Machine Learning (ML) algorithm such as the Multiple Linear Regression (MLR) in order to forecast physical weather for the next half hour. Preliminary experiments have been conducted for the proposed solution validation and the corresponding results highlighted that the performance of the everWeather station is quite satisfactory, in terms of reliability and forecasting accuracy.
Management of climate protection measures in peatland areas in Schleswig-Holstein
The peatland database application Schleswig-Holstein is presented, a web application for the management of geospatial and non-geospatial data covering peatland protection, which was designed and implemented on behalf of the nature conservation departments of the Ministry for Energy Transition, Climate Protection, Environment and Nature of Schleswig-Holstein (MEKUN) and the State Agency for the Environment of Schleswig-Holstein (LfU). The development of the web application was based on the IT requirements for the collection, research, evaluation, and reporting of peatland data. Other applications already used by the nature conservation authorities, such as a nature conservation measures database and a protected areas register, were linked to the peatland database. The implementation was carried out as a PHP application that was integrated into the Disy Cadenza evaluation and GIS platform. Particular challenges included dynamic integration of measures from the nature conservation measures database. For restoration measures, a function is provided that automatically determines the reduction of CO2 emissions.
Sustainable Mobility
Data Management of Heterogeneous Bicycle Infrastructure Data
Data that is related to traffic and specially to cycling is already commonly used in bicycle infrastructure planning processes. Data supports the understanding of bicycle use. What becomes more relevant is data about the state of the bike infrastructure. In general, cycling data sources have become in-creasingly heterogeneous what increases the need for suitable data management. This contribution presents the data management solution of the INFRASense research project that aims at the quality assessment of bicycle infrastructure. As a first step, the state of the art of data applications in cycling planning is presented. The data pipeline of the research project that considers many of these data sources is based on a Data Lake approach where the raw data sets are stored before transforming these individually for further data processing. The available data sources can be divided between time series and non-times series data. The related data models that allow the combination of different tables inside the database will be presented. As a last step, the contribution gives an outlook to forthcoming applications that will build up on the presented data management solution (interactive dashboard for data analysis).
Evaluation of Incentive Systems in the Context of SusCRM in a Local Online Retail Platform
The current consumption patterns observed in both offline and online retail present sustainability challenges related to environmental impacts associ-ated with products, last-mile delivery, personal mobility, and packaging. Different choices in delivery methods and individual mobility to overcome the last mile lead to varying levels of emissions. To address these environ-mental impacts, this study examines the application of a Sustainability Customer Relationship Management (SusCRM) approach to a local retail platform, aiming to meet customer expectations while promoting sustaina-ble and conscious consumption within the various stages of the e-commerce customer journey. Consumers nowadays tend to act in a more sustainable way at the same time, they hold retailers and logistics compa-nies responsible for creating these offers. Designing such a platform ad-dressing the demand for sustainable supply is the key goal of the research project ” R3 – Resilient, Regional, Retail in the Metropolitan Region Northwest”. To explore potential incentive systems that can be implement-ed within the platform, a survey was conducted. The survey results indicate that most respondents demonstrated a high level of acceptance towards the proposed incentive systems.
Geospatial Data Processing and Analysis of Cross-Border Rail Infrastructures in Europe
The European Union has established two major goals: the interconnection of Europe and achieving climate neutrality by 2050. Rail transport, known as the most environmentally friendly mode of transportation, has the poten-tial to bridge these goals if the right strategies are implemented. However, Europe still faces significant challenges in developing a unified rail transport network, particularly evident in the inadequate infrastructure in border areas. This study aims to address these challenges by first identify-ing all locations in Europe where cross-border rail traffic occurs and then exploring potential factors that influence the development of cross-border rail connections. To achieve this, a comprehensive literature review was conducted to identify potential influencing factors. Subsequently, a quanti-tative data analysis was performed using geographic data to identify rela-tionships and confirm potential influences. Geographical Information Sys-tems were utilized to create comprehensive datasets, providing detailed in-formation on all cross-border rail connections in Europe and their corre-sponding border regions. The analysis confirmed a strong economy and a common language as the most significant factors influencing the emergence of cross-border rail links. Surprisingly, no correlation was observed be-tween population size and the presence of cross-border rail infrastructure in border regions. In this context, it was discovered that many populous re-gions lack a direct rail connection to their neighbouring region when sepa-rated by a national border. This shows the persistent divisive nature of na-tional borders in Europe, despite the existence of the single market and freedom of movement. The datasets generated in this study offer highly ac-curate geospatial data on European cross-border rail infrastructure. These datasets hold great potential for future research endeavours across multiple domains, providing fresh perspectives on the infrastructure of border areas.

Main Track: Sustainable Practices
Sustainability Assessment in Semi-automated Solar Panels Production Facility
This research work demonstrates the potential of material and energy flow analysis (MEFA) digital tool to address sustainability concerns in Semi-automated production lines in SMEs. The paper presents the application of MEFA on a solar panels’ assembly facility in the MENA region. The importance of thorough data collection is highlighted as it allows for accurate mapping of how materials and energy are flowing through a system especially in case of manual assembly lines. The challenges in data acquisition are addressed and the improvement scenarios are presented by using simple innovative methods such as QR codes to streamline the data collection process, saving time and reducing errors. Overall, this paper demonstrates how material and energy flow modelling can be used to identify areas for improvement in sustainability practices in small and medium enterprises using simple digital tools.
A Novel Approach for Sensor Fusion Object Detection in Waste Sorting: The Case of WEEE
This paper investigates the application of AI-based methods for characterizing waste materials in sorting processes. With the increasing use of sensors in waste sorting systems, there is an opportunity to integrate data and improve accuracy. AI methods, such as deep object detection models, have the potential to optimize waste management processes and promote sustainability. This research examines the utilization of Sensor Fusion Object Detection in a multi-sensor sorting system, focusing on two different data fusion methods: concatenation and image mirroring. In the first approach, image data is concatenated with data from a hyperspectral near-infrared camera (NIR) and an inductive sensor, where dimensionality reduction techniques are applied to the data from both sensors. The second approach relies on a specific combination of NIR and inductive sensor data to simulate the format of image data. A Siamese Object Detection architecture is developed to train the model. The real-world testing results show that both approaches improve waste characterization accuracy and reliability by augmenting the models’ mean average precision (mAP). These findings demonstrate the potential for AI-based methods to transform the waste separation and management process, leading to more sustainable practices and resource efficiency.
Sustainability Analysis and Optimisation of a PET Recycling Factory in the MENA Region
This study demonstrates the use of environmental informatics methods in the MENA region, where sustainability approaches still face major challenges. The following case study focuses on the analysis and optimisation of the environmental performance of BariQ, a PET recycling factory in the MENA region. Through the application of a MEFA, an LCA and an environmental benchmarking with a competitor in Europe, the Egyptian company’s level of performance and areas with potential for improvement are identified. Additionally, a photovoltaic system is set up and evaluated as an optimisation attempt of BariQs environmental impact.

Design and implementation of a lecture for teaching current Green Coding approaches and practices at the HTW Berlin
In the research project “Potentials of Green Coding,” involving the ‘Gesellschaft für Informatik e. V.’ (GI), the ‘Umweltcampus Birkenfeld’ (UCB), and the ‘Hochschule für Technik und Wirtschaft’ (HTW Berlin), three research questions on ‘green coding’ were addressed. These focused on current ‘green coding’ concepts in software development and the Internet industry, as well as the implementation of these concepts in software development processes and existing degree program curricula. Within the third research question, led by HTW Berlin, a pilot module was developed for the Master’s program “Industrial Environmental Informatics.” The module aimed to integrate environmentally conscious and energy-efficient software development principles. Titled “Current Development Trends in Environmental Informatics,” the course imparts foundational concepts and techniques in the field, emphasizing software that is energy efficient and environmentally friendly. Students learn to optimize energy efficiency through algorithms and enhanced server performance. The modular course includes internal and external lectures, culminating in a practical component for hands-on learning. The course is influenced by current research at HTW Berlin and external experts, enhancing students’ knowledge of ‘Green IT’ and ‘green coding.’ Practical measurement exercises, based on the “Blue Angel for Software Products” standard, are conducted to explore ‘green coding’ topics, resulting in LNI short papers. This talk presents and discusses the short papers’ findings, evaluating the course concept and execution.
