PhD. Tamara Llano Astuy

Received the M.S. degree in Chemical Engineering in 2009, the post degree in Process and Chemical Engineering “Sustainable Production and Consumption” in 2010, and the B.S. degree in 2011 from the University of Cantabria. She has worked as a researcher doing the ph.D. in the GER group of the Chemistry and Process & Resource Engineering Department in collaboration with Sniace factory. Her research interest are in the areas of sulphite pulping chemistry and technology; lignocellulosic biomass characterization, hydrolysis, fractionation and detoxification; waste and industrial effluents conversion in biofuels, specifically second generation bioethanol and value-added chemical byproducts for valorization purposes.She obtained her PhD with international mention in 2016 titled “Developments in a sulphite pulping process for the valorisation of its carbohydrate resources within the biorefinery concept”

Recibió el título de Ingeniería Química en 2009, el título de Máster en Ingeniería Química y de Procesos “Producción y Consumo Sostenible”en 2010, y el título de Ingeniero Técnico Industrial en 2011 por la Universidad de Cantabria. Ha trabajado como investigadora y doctoranda en el grupo GER del Departamento de Quimica e Ingeniería de Procesos y Recursos (QuIPRe) en colaboración con Sniace. Sus intereses en investigación se centran en las áreas de tecnología y química del proceso de pasteado al sulfito; caracterización, hidrólisis, fraccionamiento y detoxificación de biomasa lignocelulósica; conversión de residuos y efluentes industriales a biocombustibles, especialmente bioetanol de segunda generación y subproductos químicos de valor añadido con motivo de su valorización. Obtuvo el título de Doctor por la Universidad de Cantabria, con mención internacional en 2016 con la tesis titulada “Developments in a sulphite pulping process for the valorisation of its carbohydrate resources within the biorefinery concept”

PhD. Tamara Llano Astuy is awarded with the 2018 extraordinary prize of doctorate of the University of Cantabria

On January 25th, 2019, the researcher and assistant professor PhD. Tamara Llano Astuy of the Chemistry and Process & Resources Engineering Department, and member of the Green Engineering and Resources (GER) group, received the honourable extraordinary prize of doctorate in the act of Santo Tomás de Aquino. The doctoral thesis entitled “Developments in a sulphite pulping process for the valorisation of its carbohydrate resources within the biorefinery concept” was supervised by PhD. Alberto Coz Fernández. The thesis evaluates the possibilities of producing fermentable substrate stream, transforming an acid sulphite pulping industry located in Cantabria (Spain) into a modern lignocellulosic biorefinery. The main objectives of the thesis were: (i) the development of several physico-chemical characterisation methods (including chromatographical analysis) of the samples, (ii) the mass balance of the main components at industrial scale, (iii) the study of the sulphite digestion stage, showing the effect of the most important parameters on the final dissolved sugars, and (iv) the implementing of several detoxification techniques (overliming, adsorption, ion exchange and liquid-liquid extraction) in order to separate the inhibitors of the sugar components. In addition, this research proposes some recommendations and improvements in the factory in order to valorise the residual streams, not only enhancing the separation of sugars from the rest of wood constituents for fermenting purposes, but also maintaining the quality properties of the main product, dissolving pulp.  


On October 1st, 2018, the Project entitled “Feasibility of Sulfated Polysaccharide Extraction and Characterization from marine macroalgae: POLIEXTRALGA“ kicked off. The project, commissioned by Spanish biotech company INVESTALGA AHTI S.L. will have a duration of 8 months and will be developed by the GER group, with Dra. Tamara Llano Astuy as Researcher in charge. The main goal of this research project is to study the feasibility of sulfated polysaccharide extraction from marine macroalgae biomass analyzing parameters affecting the auto hydrolysis such as residence time or temperature, among others. Sulfated polysaccharide extracts will be characterized in terms of monosaccharides, uronic acids, molecular weight distribution, total sulfates and total ashes.  

Added value protein from Animal by-products not intended for human consumption

On November 07, 2017, the Project entitled "Analysis and Protein Hydrolysis of Fish Bones for Human Food (HIDPROTEC)" came into force. This project, signed with HADELCA S.L. Company under the I+C=+C (SODERCAN/FEDER) Regional Program, will be developed during 7.5 months by the GER Group, with Dra. Tamara Llano Astuy as Responsible Researcher.

A primary objective of the HDPROTEC project is the optimization of the protein enzymatic hydrolysis production of value added products (such as proteins, oil, amino acids, minerals, enzymes, bioactive peptides, collagen and gelatine) from Animal by-products (ABPs) which are not intended for human consumption. Characterization of the enzymatic hydrolysates by Gel Permeation Chromatography (GPC) technique will be carried out in the R&D laboratories of the GER group as a fundamental task of the project.
