    Towards Sustainable Manufacturing: a Review and Future Directions in Additive Manufacturing of Fiber-Reinforced Polymer Composites
    (Springer Science and Business Media B.V., 2025) Türkcan, M.Y.; Tetik, Halil; Kurt, B.; Dede, Mehmet İsmet Can; Karaş, B.; Tetik, H.; Shokrani, A.; Dede, M.İ.C.
    The United Nations Sustainable Development Goals (SDGs) provide a global framework for addressing critical challenges such as climate change, resource scarcity and sustainable industrialization. With increasing demand for products and improving quality of life, linear consumption of materials and resources following the “take-make-waste” is no longer possible. As such, innovative solutions are increasingly necessary to enable circular economy in manufacturing. Additive manufacturing (AM) has emerged as a transformative technology in achieving SDGs by enhancing resource efficiency and minimizing waste. Fiber reinforced composites are a promising application of AM, as they offer the potential to optimize material use, reduce labor and support sustainable production practices. However, there is an urgent need for considering circular economy strategies, life cycle assessment (LCA) frameworks and effective recycling at the end of their lifetime. This study examines additive manufacturing systems for fiber-reinforced composites, their environmental impact and exploring the potential contributions of robotic integration in composite manufacturing to enhanced sustainability. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

    A Novel Enzymatic Delamination Method for Sustainable Recycling of Crystal Silicon Photovoltaic (c-Si Pv) Modules
    (Elsevier, 2025) Karagoz, Sadik Can; Gundogdu, Tugba Keskin; Sarialtin, Huseyin; Celiktas, Melih Soner
    Due to the growing effects of global warming, there has been a surge in the demand for renewable energy sources. In particular, the most important player in this increase is the installation of photovoltaic (PV) modules. At this critical stage, it has become a priority to identify strategic approaches for the recycling of end-of-life PV panels with a strong focus on environmental protection. This study examined the impact of enzymatic delamination on the separation of the EVA (Ethylne Viniyl Aceate Co polymer) layer, a crucial stage in the recycling process of PV panels. Notably, this investigation is the first of its kind in the existing literature. To investigate this, delamination effects of lipase, laccase, and lecitase enzymes were analyzed according to experimental design methods. Furthermore, sunflower oil was employed for the first time in the existing body of literature to facilitate delamination, resulting in a delamination rate of 100 %. The environmental impacts of these biotechnological techniques, which serve as alternatives to the commonly used toluene, were also comparatively assessed by life cycle assessment (LCA) method to analyze the environmental impact. LCA methodology was performed from gate to gate and the Recipe impact methodology was used. Oil assisted enzymatic delamination method was shown to be an alternative from environmental point of view to solvent based method such as toluene.
