Book Description
La diminution de la consommation d'eau par les fabriques de pâtes et papiers est un défi de taille. La recirculation des eaux de procédé traitées est une avenue possible. Pour que les eaux de procédé soient réutilisables, elles doivent être traitées à l'interne ou à l'externe et débarrassées en partie des matières en suspension dissoutes qui les caractérisent et qui peuvent être dommageables pour les équipements et nuire aux opérations et à la qualité des produits fabriqués. Ce rapport présente les résultats d'un projet qui visait l'adaptation d'une technologie d'ultrafiltration pour permettre la fermeture de circuits d'eaux dans une usine.

Book Description
Mise à l'essai d'un traitement par filtration biologique aérée pour l'épuration secondaire des eaux usées d'usines intégrées de pâtes et papiers. Le procédé de traitement utilisé est d'abord décrit du point de vue technologique, environnemental et économique. Ensuite, la problématique, le procédé de biofiltration au biocarbone, les résultats obtenus et les coûts d'immobilisation et d'exploitation sont présentés. Finalement, les critères de conception et de fonctionnement ainsi que le potentiel du procédé et ses limites sont discutés.

Book Description
Platform Chemical Biorefinery: Future Green Chemistry provides information on three different aspects of platform chemical biorefinery. The book first presents a basic introduction to the industry beneficial for university students, then provides engineering details of existing or potential platform chemical biorefinery processes helpful to technical staff of biorefineries. Finally, the book presents a critical review of the entire platform chemical biorefinery process, including extensive global biorefinery practices and their potential environmental and market-related consequences. Platform chemicals are building blocks of different valuable chemicals. The book evaluates the possibility of renewable feedstock-based platform chemical production and the fundamental challenges associated with this objective. Thus, the book is a useful reference for both academic readers and industry technical workers. The book guides the research community working in the field of platform chemical biorefinery to develop new pathways and technologies in combination with their market value and desirability. - Offers comprehensive coverage of platform chemicals biorefineries, recent advances and technology developments, potential issues for preventing commercialization, and solutions - Discusses existing technologies for platform chemicals production, highlighting benefits as well their possible adverse effects on the environment and food security - Includes a global market analysis of platform chemicals and outlines industry opportunities - Serves as a useful reference for both academic readers and industry technical workers

Book Description
This text presents the most current knowledge on the environmental impact of materials and products developed using nanotechnology. Although nanomaterials are revolutionising electronics, medicine, transportation and many other industries, they pose risks to living beings and ecosystems that are barely understood. Leading researchers here consider the science of nanomaterials, their behaviour in the environment, risk assessment and toxicology, and the future of nanomaterials.

Book Description
Encapsulations, a volume in the Nanotechnology in the Agri-Food Industry series,presents key elements in establishing food quality through the improvement of food flavor and aroma. The major benefits of nanoencapsulation for food ingredients include improvement in bioavailability of flavor and aroma ingredients, improvement in solubility of poor water-soluble ingredients, higher ingredient retention during production process, higher activity levels of encapsulated ingredients, improved shelf life, and controlled release of flavor and aroma. This volume discusses main nanoencapsulation processes such as spray drying, melt injection, extrusion, coacervation, and emulsification. The materials used in nanoencapsulation include lipids, proteins, carbohydrates, cellulose, gums, and food grade polymers. Applications and benefits of nanoencapsulation such as controlled release, protections, and taste masking will be explained in detail. Includes the most up-to-date information on nanoencapsulation and nanocontainer-based delivery of antimicrobials Presents nanomaterials for innovation based on scientific advancements in the field Provides control release strategies to enhance bioactivity, including methods and techniques for research and innovation Provides useful tools to improve the delivery of bioactive molecules and living cells into foods
