Life Cycle Assessment of Closed‐Loop Opaque Recycled Polyethylene Terephthalate (rPET) Bottles for UHT Milk

Packaging Technology and Science, EarlyView.
The study quantifies environmental impacts of 1 L of ultra‐high‐temperature milk bottles, comparing a 50% recycled opaque PET (rPET) bottle with 100% virgin PET bottles under closed‐loop and non‐closed‐loop recycling scenarios. Results show that 50% opaque rPET bottles outperform 100% virgin PET bottles across all impact categories, enabled by an ...

Microplastic Detectability Investigation in Soils Using X‐Ray Microtomography

X-Ray Spectrometry, EarlyView.
ABSTRACT X‐ray microtomography (microCT) is a promising tool for investigating microplastic (MP) contamination in soils, offering non‐destructive 3D visualization and quantitative analysis of particles embedded in complex matrices. This study evaluated its applicability by mixing plastic fragments (PET, PEHD, PS, and PP) with humus‐rich and sandy soils

Sexing the history of Indian anti‐colonial internationalism: White women, Indian men and the politics of the personal

Gender &History, EarlyView.
Abstract In contrast to the wealth of literature on the gendered and sexual politics of Indian nationalism, studies on the internationalisation of Indian anti‐colonial nationalism are rarely informed by the twin themes of gender and sexuality. As Indian activists traversed international political spaces in the early twentieth century, they frequently ...
