Special Issue Information

Dear Colleagues,

Today’s world is witnessing growing concern for the environment as a result of global warming, energy crises, and waste generation. The growing demand for products with a low environmental impact has led the scientific community to focus to a greater extent on sustainable and renewable materials. In this context and due to its abundant availability from various sources, cellulose has emerged as one of the most prominent candidates for sustainable use across applications in different fields,. In particular, nanocellulose presents outstanding characteristics, such as renewability, a high aspect ratio, good mechanical properties, excellent biocompatibility, hydrogen bonding capacity, reinforcing potential, and degradability.

The scope of this Special Issue is to report recent achievements in the advanced preparation and emerging applications of cellulose-based materials. In particular, topics of interest include, but are not limited to, the following:

  • Healthcare;
  • Water purification;
  • Energy storage;
  • Filtration;
  • The environment;
  • Automotive;
  • Aerospace;
  • Defense;
  • Sensors;
  • Adhesives;
  • Packaging;
  • Food;
  • Construction.

Abstract
The present study explored the extraction of cellulose from forest residues of four timber species, namely Cedrela montana Moritz ex Turcz, Buddleja incana Ruiz & Pav, Vallea stipularis L. f. and Myrsine andina (Mez) Pipoly, in the high montane forest of Chimborazo province, [...] Read more.
The present study explored the extraction of cellulose from forest residues of four timber species, namely Cedrela montana Moritz ex Turcz, Buddleja incana Ruiz & Pav, Vallea stipularis L. f. and Myrsine andina (Mez) Pipoly, in the high montane forest of Chimborazo province, Ecuador, for the sustainable utilization of leaves, branches, and flowers. An alkaline extraction method was used on the residues without the need for prior degreasing. An ANOVA analysis was applied to evaluate significant differences in cellulose extraction yields among the species’ residues. The characterization techniques used were Fourier transform infrared spectroscopy (FTIR) and polarized light optical microscopy, which confirmed the successful extraction of cellulose with characteristics comparable to standard cotton cellulose and other traditional species. The results showed significant variations in cellulose yield among the species, with Vallea stipularis L. f achieving the highest yield of 80.83%. The crystallinity of the samples was clearly evidenced by the polarity of the light in the samples during microscopy, demonstrating that the residues can be a viable and sustainable source of cellulose, contributing to a circular economy and reducing the environmental impact of forest waste.
