Integrating technology and environmental data to predict mismanaged plastic waste in a watershed
Abstract Comprehensive methods for estimating mismanaged waste accumulation in the environment are limited, especially in the Global South, and new technologies are urgently needed. Here, we applied the Azure system, a physical floating barrier designed to retain and extract river floating waste while providing observational data of mismanaged waste ...

Interactions of rare earth elements with living organisms and emerging biotechnical applications
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

Compression‐Expansion: Miniaturization, Modularity, and Logistics Beyond Earth
ABSTRACT If the Cold War space race culminated in a return to Earth, at present we are experiencing a renewed interest in space. Drawing on fieldwork among people working in the space sector in Sweden, this article focuses on some of the imaginaries underpinning this resurgence and the contemporary commercialization of space. Specifically, I hone in on

This study presents a sustainable approach for synthesizing carbon nanotubes (CNTs) via chemical vapor deposition (CVD) using polyolefins as model plastic waste as the carbon source and Ni─Co ferrite catalysts. The CNTs were applied in catalytic wet peroxide oxidation (CWPO) to degrade bisphenol A (BPA) and sulfamethoxazole (SMX), achieving efficient ...

Abstract This article presents a case study of extended producer responsibility (EPR) policies adopted by the European Union (EU) and Brazil. It focuses on waste pickers—a group increasingly visible in EU countries such as Spain and Italy. While EU directives emphasise the polluter pays principle, little attention is given to the role of informal ...

Polyolefins and polystyrene, simulating plastic solid waste (PSW), are transformed into value‐added carbon nanotubes (CNTs) through chemical vapor deposition (CVD). The CNTs are then applied in the oxidative desulfurization (ODS) of dibenzothiophene (DBT) in the oil–water biphasic system, resulting in C─S cleavage, yielding sulfur‐free products ...
