Designed to Degrade: Tailoring Polyesters for Circularity

Chemical Reviews
A powerful toolbox is needed to turn the linear plastic economy into circular. Development of materials designed for mechanical recycling, chemical recycling, and/or biodegradation in targeted end-of-life environment are all necessary puzzle pieces in ...

Combining circularity and environmental metrics to assess material flows of PV silicon

EPJ Photovoltaics, 2023
A product made from virgin raw materials that ends up in a landfill presents a linear supply chain model. Today's photovoltaic (PV) industry is still largely based on this model. With the increasing volume of production, the raw materials required for it,

Comparing the circularity and life cycle environmental performance of batteries for electric vehicles

Resources, Conservation and Recycling
Batteries account for a significant share of the life cycle impact of electric vehicles (EV). Nonetheless, the circularity and environmental performance of EV batteries remains underexplored in the literature.

Temperature-driven surface reorganization in hot-pressed CTMP sheets revealed by ToF-SIMS and chemometrics

Polymer Testing
The surface chemistry of bio-based materials governs surface properties such as adhesion but can also be central to other functional properties such as dry and wet strength; however, how temperature-driven reorganization during processing occurs is not ...
