Chapter 1. Biodegradable Polymers and Their Bionanocomposites Based on Layered Silicates: Environmental Applications
Bionanocomposites are hybrid materials comprising inorganic nanoparticles or nanofillers disposed in a biopolymer matrix. Different functional materials have been prepared using a wide type of biopolymers (naturally or synthetic) and inorganic particles (silica, metal, carbon nanotubes, cellulose nanowhiskers or layered silicate clays) with different compositions and topologies. In this chapter, special attention is paid in layered silicates because of their availability, low cost and their easy intercalation chemistry. The natural polysaccharides (chitosan, starch and alginate), proteins and the synthetic polylactic acid incorporating to layered silicates of the smectite group constitute the bionanocomposites most studied for environmental applications. In this work, the physicochemical and structural properties of developed bionanocomposites including the different methods of preparation and characterization techniques have been discussed. Finally, environmental applications of bionanocomposites based on layered silicates in the field of food, agriculture, soil and water treatments, both in cleaning and desalination, are contemplated.

Chapter 3. Preparation and Applications of Chitosan–Gold Bionanocomposites
The advancement in new technologies, industrial development and dramatic population explosion has resulted in the environment pollution. As a consequence, a sharp enhancement in the utilization of freshwater has been experienced in the last few decades leading to the generation of huge amount of wastewater.

Chapter 4. Environmental Properties and Applications of Cellulose and Chitin-Based Bionanocomposites
Bionanocomposites are class of bio-based nanostructured hybrid materials, which exhibit at least one dimension on the nanometer scale. In general, bionanocomposites are comprised of biopolymers and other organic or inorganic sources. Cellulose and chitin are the two most abundant biological polymers in nature. In recent decades, cellulose and chitin-based bionanocomposites have triggered a great deal of attention to understand such composite materials and their applications. Thanks to their renewable, biodegradable, biocompatible, low-cost, low-density, eco-friendly properties, and low energy consumption, cellulose and chitin-based bionanocomposites are excellent green technology materials. Currently, cellulose and chitin-based bionanocomposites are widely used in a variety of fields, such as environmental protection, electronics device industry, biomedicine industry, food industry, and agriculture industry. In this chapter, the sources and properties as well as the extraction and preparation methods of the corresponding cellulose and chitin bionanocomposites are introduced. The environmental characteristics of cellulose and chitin-based bionanocomposites and their applications in various fields are reported.

Chapter 5. Polylactic Acid/Halloysite Nanotube Bionanocomposite Films for Food Packaging
The average production of agricultural products globally has reached 23.7 million tons of food per day in recent years, while the destruction and waste of food annually account for a significant amount of this reform [1]. The Food and Agriculture Organization (FAO) estimates that about 1.3 billion tons of food is wasted annually, or about 15% of total annual production [2]. This number is equivalent to 33% of the average daily consumption of an adult. The U.S. Department of Agriculture (USDA) says a significant portion of this food spoilage occurs at the retail level, most related to vegetables and fruits [3]. Smarter use of food packaging can significantly reduce the waste of various foods [4].

Chapter 7. Polymeric Nano-Composite Scaffolds for Bone Tissue Engineering: Review
Bone tissues have an amazing ability to repair and regenerate. However, complex bone fractures and defects still present a significant challenge to the researchers in biomedical field. Current treatments center on autograft-allograft and metal implant to substitute bone loss. While metal implant and allograft treatments are  associated with several complications such as donor site morbidity and limited supply of material. Therefore, scaffolds can provide a new method to resolve such problems by restoring and improving tissue functions. An ideal scaffold should have biocompatible and biodegradable, as well as suitable 3D porous interconnected structure to facilitate cells and tissues in growth with proper circulation of bone mineralization. To date, various biomaterials are available for bone tissue engineering including ceramics, polymers and composites composed by calcium and phosphate bone minerals. Polymeric scaffolds can be modified to improve bioactivity and osseointegration mechanical strength in order to tailoring biological properties. In this chapter, strategies and techniques to engineer new kind of polymer surface to promote osteoconduction with host tissues will be discussed. Also, benefits and applications of polymeric composite scaffolds for orthopedic surgery will be discussed.

Chapter 8. Biodegradable Polyvinyl Alcohol/Starch/Halloysite Nanotube Bionanocomposite: Preparation and Characterization
The researchers’ attention has been drawn to the need to replace petroleum-based polymers with appropriate alternatives derived from biomass due to growing environmental and sustainability concerns (Joseph et al. in Emergent Mater. 3:1–15, 2020). As a result, biopolymers have gained widespread acceptance and have experienced significant growth in a variety of industries during the previous few decades (Rao et al. in Sci. Rev. Chem. Commun. 4:61–68, 2014). Biopolymers are an important component of bionanocomposites that have piqued the interest of researchers.

Chapter 9. Environmentally Friendly Bionanocomposites in Food Industry
Petroleum-based (fossil fuel-based) materials found versatile applications in human life. However, there are rising concerns over the use of petroleum-based products such as their adverse effects on the environment and human and animal health. In recent years, there is a mounting interest in developing bio-based materials as alternative sources for petroleum-based (fossil fuel-based) chemicals to protect the environment as well as the well-being of humans and animals.
