Policy, Waste, and Power: Textile Dumping in Chile's Atacama Desert

Latin American Policy, Volume 17, Issue 2, June 2026.
ABSTRACT Globally, 87% of textile fibers end up incinerated or in landfills, with Chile bearing the brunt of this crisis. Every year, 39,000 tons of discarded clothing are illegally dumped in the Atacama Desert, turning it into a sacrifice zone for the Global North's waste economy.

Resource Saving and Environmental Benefits From Cooking With Natural Fiber Handcrafted Boxes

Journal of Food Process Engineering, Volume 49, Issue 5, May 2026.
Cooking meals in handcrafted boxes is commonly perceived as a more sustainable option than using hobs. This paper conducts a Life Cycle Assessment (LCA) that substantiates this assumption, quantitatively demonstrating that meal preparation without the box can lead to significantly higher overall environmental impacts.

NEW LIGHTWEIGHT GYPSUM COMPOSITES FOR THE CONSTRUCTION OF LSF WALLS: A STUDY OF THERMAL BEHAVIOR

ce/papers, Volume 9, Issue 1, Page 125-134, April 2026.
Abstract This study analyses the thermal behaviour of a new lightweight gypsum material, developed in line with the principles of the circular economy, which has reduced the thermal conductivity of these compounds by up to 30.4%. Similarly, the contribution of these compounds to the energy efficiency of LSF walls with steel structures in different ...

Incorporation of MoO3 Nanoparticles Into Polypropylene Fibers via Melt Spinning: Investigation of Mechanical, Thermal, and Chromic Properties

Journal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.
Pure PP and PP/MoO 3 filaments produced by melt spinning. ABSTRACT Polypropylene (PP) composite fibers containing 0.10, 0.20, and 0.50 wt% molybdenum oxide (MoO 3 ) nanoparticles were produced via melt spinning. In the present study, the effect of this addition on the mechanical, thermal, and chromic properties of the fibers was investigated.

Optimizing biophysical properties of cellular niches to enhance stem cell‐derived extracellular vesicle function in musculoskeletal regeneration

BMEMat, Volume 4, Issue 1, March 2026.
Extracellular vesicles (EVs) derived from stem cells show promise for applications in regenerative medicine, but their scalability and yield remain challenges. This review explores the approaches for biophysical modulations within cell niches on EV properties, discusses the current clinical application of EVs, and provides an outlook on the existing ...
