High‐strength composites by thiocracking of high‐polypropylene‐content mixed waste
Polymer International, EarlyView.Mixed plastic waste made up of polystyrene and polypropylene was reacted with elemental sulfur to give high‐strength composites. Abstract Mixed‐material municipal waste poses a persistent end‐of‐life management challenge because the heterogeneous composition limits efficient separation and recycling. After disposal, mixed‐material waste often fragments

Sustainable Development, EarlyView.ABSTRACT Social considerations are often overlooked in efforts to achieve sustainable development, despite being critical for building equitable and resilient global value chains. This study addresses this gap by applying a social life cycle assessment to three key Portuguese forest wood supply chains—uncoated woodfree paper, natural cork stoppers, and

Early use of the reinforced concrete in the architecture of the Historicism in Austria–Hungary
Structural Concrete, EarlyView.Abstract The study examines the early incorporation of reinforced concrete in the architecture of Historicism in Austria–Hungary. Spanning the late 19th to early 20th centuries, the research illuminates the period's stylistic pluralism and the transformative impact of reinforced concrete.

Impact of half‐joint failures on RC girder bridges: A robustness quantification study
Structural Concrete, EarlyView.Abstract The robustness of bridge structures is critical to ensuring safety and service continuity, particularly in aging infrastructure exposed to degradation and unexpected loads. Reinforced concrete (RC) half‐joint bridges—widely built in Italy between the 1950s and 1970s—exhibit specific vulnerabilities due to inspection challenges, durability ...
