    Cradle-to-gate life cycle assessment of heavy machinery manufacturing: a case study in Türkiye
    (Springer, 2025) Ediger, Şevket Volkan; Uctug, Fehmi Gorkem; Ediger, Volkan S.; Kucuker, Mehmet Ali; Berk, Istemi; Inan, Ali; Fereidani, Bahar Moghadasi; Industrial Engineering
    Purpose Amidst accelerated industrialization and urbanization, the surge in heavy equipment production, crucial for con struction, mining, industry, and transportation, necessitates a comprehensive examination of its environmental implications from a sustainability standpoint. This study aims to scrutinize the environmental impacts of manufacturing forklifts and semi-trailers in Türkiye, employing the life cycle assessment (LCA) methodology. Methods The life cycle assessment (LCA) methodology is the foundational framework for evaluating the environmental impacts associated with forklift and semi-trailer manufacturing. A cradle-to-gate approach was employed. CCaLC2 software alongside the Ecoinvent 3.0 database and CML LCIA methodology was used. Results The carbon footprint analysis reveals that the production of a single forklift and semi-trailer generates 10.8 tons CO2eq. and 24.9 tons CO2eq. of emissions, respectively. Considering the mass of the machinery, these fgures translate to 2.8 ton CO2eq./ton machinery and 1.57 ton CO2eq/ton machinery for the forklift and semi-trailer, respectively. These results were found to be consistent with values reported for similar (but not identical) heavy machinery. Notably, the predominant share of environmental impact stems from raw material acquisition for both products, with subsequent contributions from various production stages. Steel utilization emerges as the primary contributor to all environmental impact categories, constituting an average contribution of 75%. Noteworthy exceptions include the acidifcation potential of forklift production, where the incorporation of the engine emerges as the primary hotspot with a signifcant 38% contribution. Conclusions The fndings present the environmental footprint associated with forklift and semi-trailer manufacturing, empha sizing the pivotal role of raw material acquisition, particularly steel utilization. Insights derived from this environmental impact assessment provide invaluable guidance for enhancing environmental sustainability. Decision-makers and industry stakeholders can leverage these conclusions to implement targeted measures, such as exploring alternative materials or refining production processes, to mitigate the environmental consequences of resource-intensive heavy equipment manufacturing, aligning with broader sustainability objectives.

    The Limits of Cis Compassion: The sad trans experience and its others in contemporary Turkish theatre
    (PERFORMANCE RESEAR, 2024-05-14) Yanıkcan, Ahmet Berkem; Visual Communication Design
    In the last decade, dramatic literature and theatre productions about trans women have become a significant part of Turkey's alternative theatre scene. These performances, pioneered by trans women, have been both celebrated and appropriated, with cis theatre makers often reshaping them within melodramatic conventions. Since the political ramifications of these theatrical productions are intricately linked to their narrative styles and genres, the employment of melodramatic portrayals presents emergent challenges for trans individuals, thereby culminating in a nuanced ‘transploitation’ of their narratives.While the melodramatic representations tell the stories of trans women's suffering and often end with the main character's death, the playwrights, actors, and the rest of the cast are almost always cisgender. Despite their popularity as well as aesthetic, social, and political significance, these plays have received limited scholarly attention. Moreover, the limited scholarship and public debates on them tend to treat their affective politics uncritically and even celebrate it. In the context of Turkey's liberal identity politics, these plays about trans women appear to challenge cis-heteropatriarchal oppression but ultimately reinforce cisnormative perspectives.In contrast, one-actor plays by transfeminist performers and playwrights challenge these melodramas. Characterized by themes of hope and resistance, transfeminist performances offer a contrast to mainstream portrayals of trans experience. These plays challenge the prevalent sadness in mainstream narratives about trans women, offering more empowering and representative portrayals. This juxtaposition sheds light on how sadness facilitates the experience of compassion, which both legitimizes and limits the performances about trans women.
