The food processing industries produce millions of tons of losses and waste during processing, which are becoming a grave economic, environmental, and nutritional problem. Fruit, vegetable, and food industrial solid waste include leaves, peels, pomace, skins, rinds pulp, stems, seeds, twigs, and spoiled fruits and vegetables, among other waste released in food production, which can be formed during cleaning, processing, cooking, and/or packaging. These wastes are characterized by being an important source of bioactive compounds, such as phenolic compounds, dietary fibers, polysaccharides, vitamins, carotenoids, pigments, and oils, among others. These bioactive compounds are closely associated with beneficial effects on human health. These by-products can be exploited in different industries: in food industries for the development of functional ingredients and/or new foods or natural additives; in pharmaceutical industries for medicinal, healthcare, or cosmetic products; in agricultural industries as fertilizers or animal feed; and in chemical industries, among others. The reutilization of these by-products will ensure the sustainable development of food industries and reduce their environmental impact, which will contribute to the fight against environmental problems, leading to potential mitigation of climatic change. Therefore, the determination of bioactive compound composition in agricultural and food waste and the production of extracts containing these compounds is the first step towards its reutilization.

The large production and widespread daily consumption of plastic materials which began in the last century, together with the often inadequate collection and recycling systems, have made plastics and, consequently, microplastics (MPs) ubiquitous pollutants. Microplastic pollution as a global concern is confirmed by the research papers collected in this Special Issue; these papers come from 28 Universities and research institutions and are spread across ten countries on three continents. This Special Issue collected and published 11 novel contributions focusing on microplastics in aquatic environments, their occurrence and distribution, and the effects they might have on the environment and biota. As Guest Editors of this Special Issue, we were pleased to receive several papers concerning the interaction between microplastics and biota; despite a large number of peer-reviewed papers published on this research topic, there are still several gaps that need to be filled and there is concrete evidence suggesting that microplastic pollution may constitute a serious hazard to aquatic biota. The results of the contributions collected herein have helped to fill some knowledge gaps about the occurrence, distribution, and effects of microplastics on aquatic ecosystems. The outcomes clearly indicate that microplastic pollution is a serious environmental issue; the scientific community should increase its knowledge and understanding of how it could affect the environment, biota, and humans, and how it could be reduced and prevented.

In recent years, there has been rapid growth in the availability of innovative, non-combustible products, including oral tobacco-derived nicotine (OTDN) products, heated tobacco products (HTPs), and electronic cigarettes (also referred to as e-vapor products; EVPs). Industry, academic, and government researchers are developing and validating analytical methods to extract, separate, identify, and quantitate a variety of analytes from these innovative tobacco products using a wide range of analytical techniques. These analytes include constituents such as nicotine, degradants and impurities, flavors, non-tobacco ingredients, HPHCs, and other currently unknown constituents. In this Special Issue, we received nine contributions that covered the latest analytical methods that have been developed and applied for the chemical characterization or exposure assessment to tobacco product constituents of innovative non-combustible products. This Special Issue is representative of the importance of analytical sciences research in characterizing innovative non-combustible products for guiding product design, determining relative product performance, ensuring consistency during the manufacturing process, informing toxicological risk assessment, and enabling regulatory reporting. The current advances in the development and applications of the analytical methods reported in this Special Issue can be used to inform the harm reduction potential of innovative non-combustible products for adult smokers.

Lignans are a class of natural products found mainly in plants. They have a wide variety of structures and exhibit a range of potent biological activities. Lignans are also well-known components of a number of widely eaten foods and are frequently studied for their dietary impact. Owing to these factors, lignans have been extensively studied by scientists from a large number of disciplines. This collection of research and review articles describes topics ranging in scope from the recent isolation and structural elucidation of new lignans, strategies towards the chemical synthesis of lignans, assessment of their biological activities and potential for further therapeutic development. Research showing the impact of lignans in the food and agricultural industries is also presented.

Catalyst lifetime represents one of the most crucial economic aspects in industrial catalytic processes, due to costly shutdowns, catalyst replacements, and proper disposal of spent materials. Not surprisingly, there is considerable motivation to understand and treat catalyst deactivation, poisoning, and regeneration, which causes this research topic to continue to grow. The complexity of catalyst poisoning obviously increases along with the increasing use of biomass/waste-derived/residual feedstocks and with requirements for cleaner and novel sustainable processes. This book collects 15 research papers providing insights into several scientific and technical aspects of catalyst poisoning and deactivation, proposing more tolerant catalyst formulations, and exploring possible regeneration strategies.
