Book Description
Life-cycle assessment is a methodology used to evaluate the environmental impacts of a product, process, or service during its life cycle, and risk assessment is a tool to evaluate potential hazards to human health and the environment introduced by pollutant emissions. The United Nations Sustainable Development Goals call for, among other objectives, responsible consumption and production by decoupling environmental resource use and environmental impacts from economic growth and human well-being. Life-cycle assessment and risk assessment are both analytical system approaches that allow scientists and other decision makers to address these issues and objectives according to the current understanding of environmental mechanisms. This book is the first attempt to illustrate the existing interfaces between life-cycle assessment and risk assessment and to indicate options for further integration of both tools. The second edition: Focuses on sustainability Considers new developments in life-cycle assessment and environmental risk assessment over the last ten years at the international level Introduces broader concepts and discussions on integrative versus the complementary use of life-cycle and risk assessments Extends the scope of integrated life-cycle and risk assessments to critical raw materials Includes more case studies and discusses engineered nanomaterials Featuring contributions from leading experts, Integrated Life-Cycle and Risk Assessment for Industrial Processes and Products is a great reference for graduate students and professionals in environmental management and intends to catalyze communication between life-cycle assessment and risk assessment experts and scientists in academia, industry, and governmental agencies. The practical format of the book—illustrated with flowcharts, examples, exercises, and concrete applications—makes it a useful manual for analyzing situations and making decisions.

Book Description
The incorporation of nanomaterials into products can improve performance, efficiency, and durability in various fields ranging from construction, energy management, catalysis, microelectronics, plastics, coatings, and paints to consumer articles such as foods and cosmetics. But innovation never comes at zero risk. The potential hazards resulting from human exposure during production, use, or disposal has raised concerns and targeted research early on. Safety of Nanomaterials along Their Lifecycle: Release, Exposure, and Human Hazards presents the state of the art in nanosafety research from a lifecycle perspective. Although major knowledge gaps still exist, solid data are now available to identify scenarios of critical risk as well as those of safe nanomaterial use for our benefit. The book is divided into four parts: characterization, hazard, release and exposure, and real-life case studies. To improve coherence throughout the book, various chapters review the same suite of well-characterized, judiciously chosen, and identical industrial nanomaterials. The book is a helpful resource to professionals in product development, industrial design, regulatory agencies, and materials scientists and engineers involved in the safety of nanomaterials.

Book Description
Engineered nanomaterials have been incorporated into a large number of conventional products in order to solve problems that the world has been facing. However, the current research in this area often overlooks the fact that not only using the end product but also producing it might have significant impacts on the environment and human health. Therefore, systems thinking and applying a holistic approach to assess the sustainability performance of these products is critical for decision-making. Global production and consumption of engineered nanomaterials is forecasted to increase significantly due to their applications in modern technologies, which raises concerns regarding their environmental implications. One way to analyze the environmental impacts of engineered nanomaterials is through life cycle assessment (LCA). This work investigates the cradle-to-grave environmental costs of silver nanoparticles (nAg) and global cradle-to-gate environmental costs of carbon nanotubes (CNTs) using LCA and multiple midpoint environmental impact categories in order to provide a holistic assessment. For the nAg case study, environmental performances of thirteen different synthesis routes are evaluated with cradle-to-gate boundaries and a mass based functional unit, and the results are presented in a disaggregated format based on industrial uses of nAg in a global scale. Similarly, for CNTs, the environmental impacts of eight single-walled and seven multi-walled CNTs synthesis processes are evaluated and global scale impacts of manufacturing (including raw materials) CNTs are modeled. Similar to nAg, results are segregated and presented based on industries that use CNTs the most. Results showed that as some synthesis processes are more environmentally impactful than others, and industries prefer specific processes to synthesize their nanomaterials, industry-based impacts are not exactly proportional with the industrial shares for nAg and CNTs. Following the cradle-to-gate analysis, in order to incorporate direct (or nano-specific) impacts resulting from nAg release, a physicochemical property-based characterization factor is developed using published mesocosm studies. Lastly, these findings are combined as a case study for silver enabled textiles to evaluate the necessity of nano-specific characterization factors for nAg. The case study results suggested that, calculating nano-specific impacts and incorporating them into the overall LCA results do not make a significant difference for ecotoxicity impact category unless there is a very large quantity of initial silver loading per textile. However, human health related impacts may require more attention because the release phase showed a significant sensitivity for human health LCA impacts. These results suggest the need for developing nAg specific characterization factors for human health (carcinogenics and non-carcinogenics) impact categories to be incorporated into LCA results for more thorough evaluation. While there is a need for further research, this work fills the gap in the body of knowledge surrounding environmental performances of two of the most utilized engineered nanomaterials in consumer products.

Book Description
Green nanomaterials are classed as nanomaterials with no environmentally harmful, toxic, properties. The photocatalysis of nanomaterials involves photo-conduction value in efficient removal/degradation of noxious pollutants. Green nanotechnology has objectives for the development of products and processes which are environmentally friendly, economically sustainable, safe, energy-efficient, and produce little waste or emissions. Such products and processes are based on renewable materials and/or have a low net impact on the environment. Green functionalized nanomaterials, formed by a combination of nanomaterials with natural materials or are derived through a green source, are the new trends in the remediation of pollutants in environmental industries. This has the effect of making photoactive nanomaterials work under UV/sunlight radiation in order to produce reactive radical species that rapidly remove pollutants by redox mechanism. Green Functionalized Nanomaterials for Environmental Applications focuses on recent developments in the area of fabrication of green nanomaterials and their properties. It also looks at ways of lowering the risk of exposure of green functionalized nanomaterials. This needs to be pursued in the future for investigating and assessing health risks, which may be due to exposure to green nanomaterials. It is an important reference source for all those seeking to improve their understanding of how green functionalized nanomaterials are being used in a range of environmental applications, as well as considering potential toxicity implications. Highlights innovative industrial technologies for green functionalized nanomaterials Covers major fabrication techniques for sustainable functionalized nanomaterials Shows how sustainable functionalized nanomaterials are being developed for commercial applications
