Book Description
The Royal Commission's decision to study novel materials was motivated by concern about the potential for releases to the environment arising from increasing industrial applications of metals and minerals that have not previously been widely used and, secondly, by the embodiment of nanoparticles and nanotubes in a wide range of consumer products and specialist applications in fields such as medicine and environmental remediation. Most of the evidence received focused on nanomaterials - particles, fibres and tubes on the scale of a few billionths of a metre. Chapters 2 and 3 explore the extent to which novel substances are currently being deployed, the plausible pathways by which they might enter the environment, their likely environmental destinations in use or disposal and the possible consequences of their release to those destinations. Chapter 4 considers what arrangements would be most appropriate for the governance of emerging technologies under two conditions that pose serious constraints on any regulator. First is the condition of ignorance about the possible environmental impacts in the absence of any kind of track record for the technology. Second is the condition of ubiquity - the fact that new technologies no longer develop in a context of local experimentation but emerge as globally pervasive systems - which challenges both trial-and-error learning and attempts at national regulation. Both new governance approaches and modifications to existing ones are likely to be called for. They will need to be rooted in ideas of adaptive management that require multiple perspectives on the issues. The Commission's recommendations are based on the premise that it is the functionality of the material, not particle size or mode of production, which is critical for evaluating its potential impact on the environment or human health.

Book Description
This book highlights recent research on sustainable production. In today’s manufacturing industry, cleaner production has become a central goal. “Sustainable production” describes activities that pose no threat to future generations and are not pursued at their expense. In addition, sustainable production is a concept that can improve environmental performance and focuses on technical aspects that can be used to improve efficiency and productivity. Sustainable production is not limited to the manufacturing sector, but affects all production sectors including energy, environment, and material systems – all of which face significant challenges in connection with sustainability, e.g. efforts to reduce production’s impact on the environment and to manage health and safety impacts. Key means of reducing environmental pollution from manufacturing involve reducing the main resources used in production (metals used in the machining processes, fluids/oils in production, water, and energy).

Book Description
Naturally available nanomaterials or those synthesized from natural resources become “new favorite” of material world due to their advantages of low cost, safety and environmental friendliness. They are honored as future “green materials” and widely used in fabricating various functional materials. Naturally available materials have been playing an increasingly important role in many fields such as environmental remediation, separation, catalysis, and polymer composites. This book collects latest research results on the new composites for environmental application, focusing on the study of fabricating functional composites using natural clay minerals. Naturally available materials or solid waste or minerals are good precursors for producing adsorbents. Composites based on sub-bituminous coal, lignite, and a blend of coal and Irvingia gabonensis seed shells, the Cl-type Mg-Al hydrotalcite (Cl-LDH), the hydroxyapatite decorated with carbon nanotube and Zirconium (Zr)-containing silica residue purification (ZSR-P) were proved to have good adsorption capability to Cd(II) and Pb(II) ions, antibiotic molecules, Cd(II), and fluoride, respectively. The nano-Mg(OH)2 loaded carbon cloth showed good separation effect for Eu(III), and the sodium-modified clinoptilolite showed good separation effect for CH4/N2 from coal bed gas. Also, natural nanoclay is an effective precursor for the preparation of inorganic-inorganic or organic-inorganic nano-hybrid materials. Using nano-kaolinite as a carrier, the inorganic-inorganic hybrid cobalt blue pigment with excellent color and stability can be obtained by surface co-precipitation and in-situ calcination crystallization process. The intercalation of 7-amino-4-methylcoumarin (AMC) molecules into the interlayer space of montmorillonite (MMT) can effectively inhibit fluorescence quenching and improve the detection effectiveness of Cr(VI) in water. The interlayer space of kaolinite can accommodate organic molecules to form an organic-inorganic hybrid composite. Natural clay minerals are also effective carriers for catalysts. Er3+:CeO2/palygorskite nanocomposites prepared by a facile precipitation method showed excellent desulfurization rate under visible light irradiation. The zero-valent iron-loaded nanoclays composite catalysts can degrade efficiently Rhodamine 6G (Rh 6G) under microwave irradiation. In addition, the polymer composites have been developed using natural palygorskite, montmorillonite nanosheets or silica nanoparticles as inorganic components, which are potential to be used in many fields such as packing, biomedicine, or rubber. With the increasing attention to clay minerals, research methods for the microstructure of clay minerals continue to receive attention. It is no doubt that natural materials have got a booming attention from researchers in mineralogy, materials science, chemistry, energy, biomedicine and other fields due to their advantages. However, there is still a long way to go to substitute traditional synthetic nanomaterials with natural ones, and there are still theoretical and technological limitation in the design and synthesis of new materials from natural materials. Related theoretical research and technological development require continuous exploration by researchers. This book has collected some recent advances in related research, and hopes to play a role in attracting more attention to the construction of functional materials from natural raw materials. It is also believed that through the unremitting efforts of all researchers, the dream of green materials and green preparation processes can be realized.
