Degradation mechanisms of curaua, hemp, and sisal fibers exposed to elevated temperatures [PDF]

BioResources, 2019
The influence of elevated temperatures on mechanical behavior was studied for curaua, hemp, and sisal natural fibers. Tensile tests were performed on fibers heated at 100 °C, 150 °C, and 200 °C for 24 h, and reference samples were maintained without thermal treatment for comparisons.

Valorization of coffee silverskin by cascade extraction of valuable biomolecules: preparation of eco‐friendly composites as the ultimate step

Biofuels, Bioproducts and Biorefining, Volume 18, Issue 2, Page 524-542, March/April 2024.
Abstract This study presents a multidisciplinary approach for dealing with the environmental problems related to agro‐industrial coffee residues. The exploitation of these residues allows biomolecules to be obtained from renewable sources and enables the preparation of CO2‐neutral biocomposites, with the advantages of reducing fossil depletion ...
