Barley Straw (Hordeum vulgare) as a Supplementary Raw Material for Eucalyptus camaldulensis and Pinus sylvestris Kraft Pulp in the Paper Industry
Vargas González, Fátima; González, Zoilo; Rojas, Orlando; Garrote, Gil; Rodríguez Pascual, Alejandro (NC State University, 2015)The present study shows that barley straw (Hordeum vulgare) can be a supplementary raw material of softwoods and hardwoods such as Pinus sylvestris and Eucalyptus camaldulensis, respectively, for the production of ... -
Biorefinery Process Combining Specel® Process and Selective Lignin Precipitation using Mineral Acids
Domínguez-Robles, J.; Espinosa, E.; Savy, Davide; Rosal, Antonio; Rodríguez Pascual, Alejandro (NC State University, 2016)Soda black liquors from the Specel® process, which used wheat straw as the raw material, were subjected to an acid precipitation process to recover the lignin. Lignin was isolated by acid precipitation using three different ... -
Cellulosic pulps of cereal straws as raw material for the manufacture of ecological packaging
Vargas González, Fátima; González, Zoilo; Sánchez, Rafael; Jiménez, Luis; Rodríguez Pascual, Alejandro (NC State University, 2012)The aim of this work was to study the potential application of four types of cereal straws: oats, maize, rapeseed, and barley, in order to obtain cellulose pulp through the Specel® process for use in the manufacture of ... -

Improvement of TCF bleaching of olive tree pruning residue pulp by addition of a laccase and/or xylanase pre-treatment
Martín-Sampedro, Raquel; Rodríguez Pascual, Alejandro; Requejo Silva, Ana; Eugenio, María E. (NC State University, 2012)This study aimed at assessing the biobleachability of soda pulps obtained from olive tree pruning residue. The enzymatic (LMS) pre-treatment was applied prior to a simple totally chlorine free (TCF) bleaching sequence, ... -
Nanocellulose-Based Inks—Effect of Alginate Content on the Water Absorption of 3D Printed Constructs
Espinosa, E.; Filgueira, Daniel; Rodríguez Pascual, Alejandro; Chinga-Carrasco, Gary (MDPI, 2019)2,2,6,6-tetramethylpyperidine-1-oxyl (TEMPO) oxidized cellulose nanofibrils (CNF) were used as ink for three-dimensional (3D) printing of porous structures with potential as wound dressings. Alginate (10, 20, 30 and 40 ... -
Optimization of ECF bleaching and refining of kraft pulping from olive tree pruning
Requejo Silva, Ana; Rodríguez Pascual, Alejandro; Colodette, Jorge L.; Gomide, José L.; Jiménez, Luis (NC State University, 2012)The aim of the present work was to find an optimum kraft pulping process for olive tree pruning (OTP) in order to produce a bleachable grade pulp of Kappa number about 17. The kraft pulp produced under optimized conditions ... -
