Title: Bibiana Ribeiro Rubini: Innovator in Microfibrillated Cellulose Production
Introduction
Bibiana Ribeiro Rubini is a notable inventor based in Jacareí, Brazil. She has made significant contributions to the field of cellulose processing, particularly in the production of microfibrillated cellulose and nanocellulosic materials. With two patents to her name, her work is paving the way for advancements in sustainable materials.
Latest Patents
Rubini's latest patents include a process to produce microfibrillated cellulose by impacts. This invention relates to a method of obtaining fibrillated microfibrillated cellulose by subjecting cellulose fibers in a slurry of cellulose pulp to multiple mechanical impacts. The process involves using non-cutting bars arranged in a ring formation, where two rings concentrically arranged face each other in high rotation to transmit kinetic energy to the fibers. This results in highly defibrillated microfibrillated cellulose.
Another significant patent is for a process for producing a nanocellulosic material that comprises at least two stages of defibrillation of cellulosic feedstock and at least one intermediate fractioning stage. This invention utilizes fractioning of the cellulosic pulp stream from pre-treatment or mechanical defibrillation, allowing both accept and reject fractions to be adjusted for consistency before undergoing further defibrillation stages.
Career Highlights
Rubini is currently employed at Suzano S.A., a leading company in the pulp and paper industry. Her work focuses on innovative processes that enhance the efficiency and sustainability of cellulose production.
