The microbiome science of composting and human excrement composting: a review [PDF]

arXiv
Linear waste management systems are unsustainable and contribute to environmental degradation, economic inequity, and health disparities. Among the array of environmental challenges stemming from anthropogenic impacts, the management of human excrement (human feces and urine) stands as a significant concern.

4D Printing of Polyethylene Glycol‐Grafted Carbon Nanotube‐Reinforced Polyvinyl Chloride–Polycaprolactone Composites for Enhanced Shape Recovery and Thermomechanical Performance

Advanced Intelligent Systems, EarlyView.
This study introduces polyethylene glycol‐functionalized carbon nanotubes (CNTs) to enhance dispersion, interfacial bonding, and 4D printability in polyvinyl chloride‐PCL nanocomposites. The optimized 4D composite (0.5 wt% CNT) achieves a 25% increase in tensile strength, 95.78% shape fixity, and 5‐s recovery time.

Hydrophilic Particles Exit While Hydrophobic Particles Persist Following In Vivo Biodegradation of Nanoparticle‐Laden Polymeric Devices

Advanced NanoBiomed Research, EarlyView.
Functionalizing biomedical implants with nanoparticle contrast agents introduces imaging capabilities to devices, improving patient care by avoiding inherent complications. However, nanoparticle surface chemistry optimized for device manufacturing may not lead to efficient nanoparticle clearance from tissues.

Biobased, biodegradable and compostable plastics: chemical nature, biodegradation pathways and environmental strategy

Environmental Science and Pollution Research
Increasing pollution of plastic waste is one of the major global environmental threats, deteriorating our land, water and air. The shift towards biobased, biodegradable and compostable plastics is considered a green alternative to petroleum-based plastic due to its renewable source or biodegradability.
