Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

Bioinspired Regenerative Lignification Enables Ultra‐Hard and Sustainable Bamboo Structural Materials

Exploration, EarlyView.
Developing strong and sustainable materials is essential for reducing reliance on metals and lowering carbon emissions. Inspired by how plants naturally harden their cell walls, we created a rapid process that transforms bamboo into an ultra‐hard structural material by rebuilding lignin‐like networks within its structure.

Hydrothermal Pretreatment of Hardwood Chips Prior to Alkaline Pulping and D0(EP)D1 Bleaching

BioResources, 2014
In this study, mixed southern hardwood was pretreated via a hydrothermal process at 160 °C for 1 h. Alkaline pulping was then conducted on both the pretreated and original chips to prepare pulp with Kappa 17 and 30.

Extended Oxygen Delignification with the Oxy TracTM Process

JAPAN TAPPI JOURNAL, 2000
Many mills have adopted oxygen delignification systems in order to decrease chemical consumption in a bleaching plant since 1970's.Generally, the maximum delignification obtained by oxygen delignification system keeping pulp strength has been considered about 50% for softwood pulp because possible delignification by oxygen is limited to certain groups ...

Impact of Hot-Water Extraction on Acetone-Water Oxygen Delignification of Paulownia Spp. and Lignin Recovery

Energies, 2014
A hardwood-based biorefinery process starting with hot-water extraction (HWE) is recommended in order to remove most of the hemicelluloses/xylans before further processing. HWE may be followed by delignification in acetone/water in the presence of oxygen

Acid Sulfite Pulping of Hemp: Effects of Processing Conditions on Lyocell Pulp Quality

Journal of Polymer Science, EarlyView.
Industrial hemp is emerging as a promising renewable source for next‐generation textile fibers. This study evaluates whether acid sulfite pulping can produce hemp‐based dissolving pulp suitable for lyocell manufacturing. While the process is historically linked to increased cellulose accessibility, it did not achieve the low lignin content and ...
