Polymer‐Based Recycling Strategies for Plastic Waste: A Comprehensive Review

Environmental Quality Management, Volume 35, Issue 3, Spring 2026.
ABSTRACT Plastic pollution has emerged as one of the most pressing global environmental challenges, affecting ecosystems, human health, and climate through persistent waste accumulation and microplastic formation. This comprehensive review elaborates on recycling techniques based on polymer, including mechanical and chemical recycling, advantages and ...

Changes in Shell and Crystal Structure From Life to Sediments: An EBSD Characterization of Subantarctic Planktic Foraminifera

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Fossil foraminifera store a wealth of information about past climates and ecosystems in their shell chemistry. However, these element and isotope signals may be affected by post‐mortem diagenesis (i.e., alteration). Here, we use Electron Backscatter Diffraction (EBSD; crystal orientation mapping) to evaluate the structural integrity of sub ...

Constraining Greenhouse Gas Cycling and Emissions in Africa's Largest Humic Lake

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Humic tropical lakes and wetlands are globally important sources of atmospheric greenhouse gases (GHGs). However, mechanistic insight into GHG cycling in such systems remains limited—especially in understudied central Africa. To address this, here we measured high‐, falling‐, and low‐water seasonal concentrations and isotopic compositions of ...

A comprehensive overview and recent advances on polyhydroxyalkanoates (PHA) production using various organic waste streams.

Bioresource Technology, 2021
Polyhydroxyalkanoates (PHA) are appealing as an important alternative to replace synthetic plastics owing to its comparable physicochemical properties to that of synthetic plastics, and biodegradable and biocompatible nature.
