Blending short rotation coppice poplar with wheat straw as a biorefinery feedstock in the State of Washington
Dou, Chang; Bura, Renata; Ewanick, Shannon; Morales-Vera, Rodrigo (2019)To ensure an uninterrupted feedstock supply, commercial-scale cellulosic biofuel production facilities must consider using more than one type of biomass; this paper considers the use of poplar and wheat straw. Short rotation ...

Cellulases production by a trichoderma sp. using food manufacturing wastes
Gordillo-Fuenzalida, Felipe; Echeverría-Vega, Alex; Cuadros-Orellana, Sara ; Faúndez, Claudia; Kähne, Thilo; Morales-Vera, Rodrigo (2019)The cost of cellulase enzymes is a main contributor to the operational cost of a biorefinery producing ethanol from lignocellulosic material. Therefore, onsite production of enzymes using low-value substrates might be an ...

Desulfurization of vulcanized rubber particles using biological and couple microwave-chemical methods
Valdés, Cristian; Hernández-Sepúlveda, Camila; Morales-Vera, Rodrigo; Andler-Osorio, Rodrigo (2021)Currently, recycling or degradation treatments for tires are an enormous challenge. Despite efforts to dispose of or recycle it, rubber waste is increasing year by year worldwide. To create a rubber-recycling system, several ...

Life cycle assessment of bioethanol production: a case study from poplar biomass growth in the U.S. pacific northwest
Morales-Vera, Rodrigo; Vásquez-Ibarra, Leonardo; Scott, Felipe; Puettmann, Maureen; Gustafson, Richard (2022)Biomass appears to be one of the most prominent renewable resources for biofuels such as bioethanol, mainly due to its better environmental performance compared with fossil fuels. This study addresses a comprehensive ...

Production routes to bio-acetic acid: life cycle assessment
Budsberg, Erik; Morales-Vera, Rodrigo; Crawford, Jordan T.; Bura, Renata; Gustafson, Rick (2020)Background: Similar to biofuels, numerous chemicals produced from petroleum resources can also be made from biomass. In this research we investigate cradle to biorefinery exit gate life cycle impacts of producing acetic ...

Techno-economic analysis of producing glacial acetic acid from poplar biomass via bioconversion
Morales-Vera, Rodrigo; Crawford, Jordan T.; Dou, Chang; Bura, Renata; Gustafson, Rick (2020)Most of the current commercial production of glacial acetic acid (GAA) is by petrochemical routes, primarily methanol carbonylation. GAA is an intermediate in the production of plastics, textiles, dyes, and paints. GAA ...
