This book examines the state of the art of biosorption as an economical and environmentally friendly technique for pollutant removal in wastewater. Several articles are included that develop the applications of biosorption showing the high efficiency and versatility of this process, as well as showing recent advances in this field. Different modalities of biosorption are demonstrated from free biomass to immobilized biomass, as well as the combination of biomass with modern materials to form composites, emphasizing the significant versatility of this technique. In addition, different examples with biomasses of very different natures are also included and discussed, as are the factors that influence biosorption processes. Other contributions offer some examples of apparently useless materials that are reused and applied in the elimination of pollutants. Therefore, this book is an excellent complement for those researchers who work on biosorption as well as a starting point for those who want to begin research on this topic.

Kinetics and reactor modeling for heterogeneous catalytic reactions are prominent tools for investigating and understanding catalyst functionalities at nanoscale and the related rates of complex reaction networks. This book illustrates some examples related to the transformation of simple to more complex feedstocks, including different types of reactor designs, i.e., steady-state, transient plug flow reactors, and TAP reactors for which there is sometimes a strong gap in the operating conditions from ultra-high-vacuum to high-pressure conditions. In conjunction, new methodologies have emerged, giving rise to more robust microkinetics models. As exemplified, they include the kinetics and the dynamics of the reactors and span a large range of length and time scales. The objective of this Special Issue is to provide contributions that can illustrate recent advances and novel methodologies for elucidating the kinetics of heterogeneous reactions and the necessary multiscale approach for optimizing the reactor design. This book is dedicated to postgraduate and scientific researchers, and experts in heterogeneous catalysis. It may also serve as a source of original information for the elaboration of lessons on catalysis for Master students.

Bioenergy is renewable energy obtained from biomass—any organic material that has stored sunlight in the form of chemical energy. Biogas is among the biofuels that can be obtained from biomass resources, including biodegradable wastes like manure, sewage sludge, the organic fraction of municipal solid wastes, slaughterhouse waste, crop residues, and more recently lignocellulosic biomass and algae. Within the framework of the circular economy, biogas production from biodegradable waste is particularly interesting, as it helps to save resources while reducing environmental pollution. Besides, lignocellulosic biomass and algae do not compete for arable land with food crops (in contrast with energy crops). Hence, they constitute a novel source of biomass for bioenergy.Biogas plants may involve both high-tech and low-tech digesters, ranging from industrial-scale plants to small-scale farms and even households. They pose an alternative for decentralized bioenergy production in rural areas. Indeed, the biogas produced can be used in heaters, engines, combined heat and power units, and even cookstoves at the household level. Notwithstanding, digesters are considered to be a sustainable technology that can improve the living conditions of farmers by covering energy needs and boosting nutrient recycling. Thanks to their technical, socio-economic, and environmental benefits, rural biogas plants have been spreading around the world since the 1970s, with a large focus on farm-based systems and households. However, several challenges still need to be overcome in order to improve the technology and financial viability.

New trends in the cereal industry deal with the persistent need to develop new food goods tailored to consumer requirements and, in the near future, to the scarcity of food resources. Concepts of sustainable food production and food products as health and wellness promoters, the use of organic ingredients such as new ancient cereals to produce redesigned old staple foods, or the use of byproducts in designed food or feed formulations, in accordance with the bioeconomy and sustainability principles, are current topics that act as driving forces for innovation. The structure of cereal-based food products, especially in the case of gluten- or wheat-free foods, has proven to be a determinant for food appeal and strongly impacts consumer acceptance. It is well known that products with the same chemical composition can present very different structures, resulting in differently perceived texture and sensory properties and, therefore, rheology is an important tool for the food cereal industries. These are topics that act as driving forces for innovation and will be discussed in the present Special Issue.
