    Greenmetric Journey of Izmir Institute of Technology: Agile Strategies Towards a Green Campus
    (Springer Science and Business Media Deutschland GmbH, 2026) Keskin, E.; Ökten, H.E.; Akpinar, İ.; Baran, Y.
    Recently, there has been growing attention towards sustainable approaches on university campuses through disseminating international evaluation systems, the UI GreenMetric World University Rankings (GM) attracting specific attention in particular. Türkiye is one of the countries where the number of participating universities in GM rises annually at a significant pace. Most of the large-scale university campuses in Türkiye were already built by the 1990s, which led these campuses to adapt themselves to higher standards for sustainability. In this context, Izmir Institute of Technology (IZTECH), a 33-year-old university, has applied for the GM with its Gülbahçe Campus since 2020. This paper aims to reveal IZTECH’s institutional agile sustainability strategy, energetic and collective processes, and good practices in the last five years while examining the outcomes through the GM’s evaluation of six assessment criteria. In this regard, the sustainability practices of IZTECH have been monitored since 2019 and compared to how the developments have improved the GM scores for the past 3 years. This study, focusing on the IZTECH campus through historical, social, educational, and technological perspectives, unveils the barriers between developing and implementing sustainability practices and examines the cohesion between GM scores and annual reports of campus activities for further projections towards a greener campus. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2026.

    The Role and Potential Sources of Sustainable Plant-Based Foods: a Look to the Future
    (Sidas Medya A.S., 2025) Çakıtlı, G.; Nurko, E.
    The food industry, influenced by environmental issues such as global warming and climate change, is undergoing significant changes towards establishing a sustainable food system. This system prioritizes reducing the adverse impacts on our natural resources while ensuring sufficient and nutritious foods. Despite animal sources being rich in nutrients, consumer concerns regarding sustainability are increasing the search for alternative sources. With growing consumer interest in sustainable and healthy choices, there is an increasing demand for plant-based food sources. Plant-based protein sources generally include seeds, legumes, nuts, and oilseeds. Plant-based proteins are not only consumed as a food but also valued for their potential for various techno-functional properties in the food industry. Plant-based foods are both good sources for proteins and high in fiber, vitamins, and minerals. This study focuses upon the impact of a developing world and increasing population on plant-based foods, their nutritional value, and potential applications. © 2025 Sidas Medya A.S..

    A Comprehensive Life Cycle Impact Evaluation of Hydrogen Production Processes for Cleaner Applications
    (Pergamon-elsevier Science Ltd, 2025) Goren, A. Yagmur; Dincer, Ibrahim; Khalvati, Ali
    The worldwide energy demands have greatly increased with urbanization and population growth. Air pollution, acid rain, greenhouse gas emissions, global warming originating from CO2 emissions, depletion of energy supplies, and environmental degradation resulting from climate change are all consequences of using non-renewable fossil fuel-based energy infrastructure. To minimize emissions, renewable energy-based alternative energy sources must be investigated. In this regard, hydrogen (H2) has emerged as a promising fuel to meet energy requirements, and green H2 production with net-zero emissions has gained significant interest in recent years. Therefore, this study uses the life cycle assessment approach to evaluate the atmospheric emissions and environmental impact parameters of the gasification, electrolysis, and dark fermentation-microbial electrolysis hybrid process and assess their sustainability levels, considering the sustainable development goals. Among the studied H2 production processes, the maximum CO2 emission originates from the coal gasification process, accounting for 18.6 kg-CO2/kg-H2, while the alkaline electrolysis process provides the lowest total CO2 emission of 6.39 kg-CO2/kg-H2. Furthermore, the biological-based dark fermentation-microbial electrolysis cell process is a promising option owing to its highest negative biogenic CO2 emission of -68.69 kg-CO2/kg-H2. The environmental impact parameters of the studied processes are calculated considering the emissions, and the highest global warming potential of 21.75 kgCO2-eq./kg-H2 is obtained for the coal gasification process, considering the life cycle assessment coefficients. Overall, the lowest atmospheric emissions and environmental impacts are obtained for the electrolysis process. Consequently, these results revealed that switching from the fossil fuel resources used in the conventional H2 production methods to fully sustainable sources, such as renewables, can make energy production methods entirely sustainable from an environmental point of view.

    Synthesis of Nannochloropsis Oculata Cultivation Process Based on Mixed-Integer Formulations
    (Elsevier, 2025) Kivanc, Sercan; Tuncer, Basak; Deliismail, Ozgun; Sildir, Hasan
    Sophisticated mathematical formulations and related optimization tasks are important to favor microalgae processing. This study focuses on the development of a mixed integer nonlinear programming approach to calculate design and operational decisions through simultaneous and rigorous approach under set of complex constraints and objective functions. Through a set of differential algebraic equations, whose model parameters are obtained through fitting a dataset available in the literature, three case studies are demonstrated for the calculation of optimum cultivation conditions based on economic considerations and biomass production. The case studies show the impact of the approach for the sustainability of the process as different conditions are primary defined by light color, reactor size, dilution rate, feed stream composition, and growing medium are required for desired tasks. The approach is flexible and further modifiable to various considerations for more complex decision-making problems.

    Life Cycle Assessment of Black Tea Production and Consumption in Turkiye: Insights From Waste Management Scenarios
    (Elsevier, 2025) Uctug, Fehmi Gorkem; Küçüker, Mehmet Ali; Ediger, Volkan S.; Kucuker, Mehmet Ali; Berk, Istemi; Inan, Ali; Tugcu, Melisa
    This study conducts a life cycle assessment (LCA) of tea production and consumption in T & uuml;rkiye, the world leader in per capita tea consumption. Aiming to identify environmental hotspots and propose sustainable solutions, a cradle-to-grave LCA was performed using CCaLC2 software, CML methodology, and the Ecoinvent 3.0 database. It covers cultivation, processing, transportation, and consumption stages, focusing on key environmental indicators like carbon footprint and acidification potential. The results reveal that consumption dominates the environmental footprint (91%) due to energy-intensive brewing methods. Cultivation and transportation contribute minimally (4% each). This highlights the need for promoting energy-efficient brewing practices and consumer adoption of renewable energy sources. The study also explores the environmental implications of different waste management strategies. Composting emerged as the most beneficial approach for reducing the carbon footprint and photochemical oxidants creation, while incineration might be preferable for other impact categories. This study underscores the importance of addressing energy consumption during tea brewing and encouraging renewable energy use among consumers. Additionally, it promotes composting as a crucial waste management strategy for a more sustainable tea value chain in T & uuml;rkiye. These findings offer valuable insights for policymakers, industry players, and tea drinkers to make informed decisions that minimize environmental impact.

    A Literature Review on Sustainable Buildings and Neighborhoods in Terms of Daylight, Solar Energy and Human Factors
    (Elsevier, 2025) Cogul, Ilgin cataroglu; Kazanasmaz, Zehra Tugce; Ekici, Berk
    Sustainability has become the focus and interest of researchers with climate change's increasing impact and challenges. Considering various perspectives, published studies focus on sustainability in architecture and the built environment, such as using daylight more effectively, enhancing energy efficiency, and designing nearly zero-energy buildings. Given the attention to sustain- ability in this domain, this review assesses the abovementioned viewpoints in buildings regarding environmental factors in relation to the micro and macro scales of the buildings and neighborhoods. Human factor has increasingly been of interest in recent works of sustainable environments. This study identifies the gaps with respect to architectural design elements considering daylighting, energy efficiency and human factors on building and neighborhood scales. A comprehensive table of the reviewed studies summarizes the aim, methodology, optimization algorithm, objective function, machine learning algorithm, digital tools, location, independent and dependent variables, view, wellness, well-being, daylight/energy performance metrics, scale, and solar strategy. The results showed that the current state-of-the-art focus on energy efficiency mainly considers passive design strategies at the building scale. Studies in the daylight domain primarily consider window properties, shading devices, and orientation. Human-centric studies showed that daylighting improves the emotional well-being of building occupants but can have negative effects such as overheating and glare. Overall findings emphasize the necessity of a holistic approach in achieving sustainability goals in dwellings at the building and neighborhood scale.

    Dynamic and Stochastic Optimization of Algae Cultivation Process
    (Pergamon-elsevier Science Ltd, 2025) Kivanc, Sercan; Beykal, Burcu; Deliismail, Ozgun; Sildir, Hasan
    This study offers a realistic representation of system dynamics which accounts for light intensity, biomass, substrate, and nitrogen concentration, by employing stochastic programming techniques to account for spatial and temporal variations for algae growth. The optimization task focuses on lipid productivity and selectivity, which are crucial factors in the context of algal biofuel production. Different scenarios from likely and unlikely cases of model parameters were evaluated. Optimal initial conditions for key variables such as nitrogen, substrate, light, biomass, lipid, and surface light intensity are calculated, considering the uncertainty of the parameters as well as other governing equations. The results show that a remarkable 11.18% increase in lipid productivity compared to a reference scenario. Furthermore, in the stochastic case, our results highlight that uncertainty has a disproportionately large effect on biomass in comparison to lipid concentration, providing valuable insights into the behavior of the system under varying conditions. This provides a comprehensive exploration of the parameter uncertainty on lipid productivity and algal growth.

    Small Wins in Practice: Learnings From 16 European Initiatives Working Towards the Transformation of Urban Food Systems
    (Elsevier Sci Ltd, 2024) Rao, Madhura; Luger, Jonathan; Regeer, Barbara J.; Lopez, Cristina Yacoub; Wilde, Danielle; Wilde, David; vander Meij, Marjoleine G.
    In this study, we examine how 16 initiatives across Europe are addressing 'wicked' food system issues by mobilising local networks and implementing small-scale but impactful changes in urban and peri-urban regions. To map the potential of these initiatives to contribute to large-scale change, we apply the Small Wins Framework proposed by Termeer & Dewulf (2019). By analysing data collected through interviews with participants working on initiatives spanning 13 cities across 9 European countries, we identify the manifestation of six propelling mechanisms that signal the capacity of small wins to bring about systemic change. Findings from this study reveal the presence of most mechanisms across the included initiatives. However, the ways in which these mechanisms appear depend on various factors such as stakeholder motivation, the maturity of the initiative, the need for additional funding, local food culture, and the regional and national political landscape among others. Our analysis indicates that the Small Wins Framework could be successfully used as a mapping tool in urban transformation processes, but it is likely to be more effective as a tool for reflexive monitoring rather than ex-post evaluation. Drawing on the impacts of various large-scale disruptions on the initiatives, we suggest that social, political, and economic shocks can present windows of opportunity to accelerate change and that initiatives performing well under such pressure should be supported in their pursuit of systems transformation. Lastly, we recommend non-linear growth strategies such as spreading, deepening, and expanding, as ways to compound the impact of small wins.

    Local Innovation in Emerging Creative Ecosystems
    (Taylor and Francis, 2017) Mengi,O.; Velibeyoglu,K.
    Globally, most future economic growth will occur in regional cities, but infrastructure and employment are often inadequate. In short, default development approaches may focus on shaping the urban form (infrastructure/housing) at the expense of the institutional and intangible factors driving jobs growth, such as creativity, innovation and sector productivity. Effective local partnerships can help counter the limitations of default approaches to urbanism. Analyses reveal that the wedding wear sector in Izmir, Turkey, in particular is in many respects unique, with great potential as an emerging cluster due to its inherited knowledge and knowhow, yet still lacks in design considerations, and is in desperate need of promotion, advertisement and cost-effective returns. Therefore, the main lesson is that enabling interactions between the local government, NGOs and firms both inside and outside the cluster can promote smart development. At policy level, establishment of an incubator within a four-leg structure is an effective local development partnership. In a practical Turkish context, Chapter 5 investigates the institutional and partnership management arrangements to facilitate such urban innovation hubs for creative ecosystems. © 2018 selection and editorial matter, Simon Huston; individual chapters, the contributors.
