R̩seau MRQ Р20 minutes de science avec Rafael Eloy De Souza (LTB)

La présentation sera en anglais.

Rafael est diplômé en ingénierie forestière et a obtenu une maîtrise en technologie des produits forestiers à l’Universidade Federal Rural do Rio de Janeiro, au Brésil. Il est spécialisé dans la science et la technologie du bois, la production de panneaux de bois et la synthèse d’adhésifs, en particulier la lignine kraft pour la synthèse d’adhésifs destinés aux panneaux de bois. Il a aussi fait de la recherche sur les adhésifs urée-formaldéhydes et phénol-formaldéhydes. et sur la qualité du bois pour la production de panneaux en bois et de cellulose. Rafael a aussi travaillé sur des projets de production de biocarburants solides à partir de déchets lignocellulosiques. Il est actuellement étudiant au doctorat en génie chimique au Laboratoire des technologies de la biomasse (LTB) de l’Université de Sherbrooke.

Use of natural resources as a replacement for raw material from petroleum has gained increasing attention from the scientific community regarding the use of these resources as substitutes for products derived from petroleum. The great challenge of reducing carbon emissions into the atmosphere has led not only to the study of the use of natural resources, but also the use of by-products from various industrial processes in energy generation. However, because these by-products have already been modified previously in the industrial process, their characteristics and properties change, which ends up generating an intrinsic challenge to the material for its use in energy generation. As an example of these new uses, we can mention pellets. Pellets are densified materials that are produced, often from biomass residues, for energy production. Since then, different types of materials have been studied in the manufacture of pellets in order to find a new raw material for its production. However, not all the raw materials tested have generated pellets with satisfactory quality for its use, since these products must meet the standardization rules established for their use. In everyday life, paper, which is a product from biomass, is present in many ways, whether in the form of packaging or as part of an everyday product. The management of this waste has become an area of concern for many establishments. There is no much information available on the suitability and processes of pelletizing different waste paper for use as biofuels. Thus, our objective is to discuss the main challenges that the use of waste paper has brought to its use as biofuel.
