“…In the recent years, there was an increasing interest of both academic and industrial research on foamed materials paying particular attention in the development of environmentally friendly processes and materials that can be used in these high-volume productions [4][5][6]. In this context, biodegradable polymers obtained by renewable sources can be considered a possible approach to reduce the overall environmental impact and solve the disposal problem, especially when recycling is difficult or when biodegradation is a functional requirement of the product [7][8][9].…”

“…Foams made from conventional fossil-based polymers, such as expanded polystyrene (EPS) and polyurethane (PU), are frequently used in the food packaging sector. However, these polymers do not degrade naturally, and recycling them is not profitable, whereas foams produced from biodegradable polymers could be a promising solution to solve the disposal problem posed by petroleum-based polymeric foams [117][118][119]. Alongside starch, the most investigated biodegradable polymers for the development of biodegradable composite foams are polybutylene succinate (PBS), polycaprolactone (PCL), polylactic acid (PLA), and polyvinyl alcohol (PVOH) [117,118,120].…”

“…Several strategies, especially the formation of composites using additives, reinforcing fibers, fillers, or blending between materials, have been investigated to improve biodegradable foams' properties [118,120]. De Carvalho et al [121] produced cassava-starch-based biodegradable foam trays coated with polyvinyl alcohol (PVOH) with a higher degree of hydrolysis.…”

Advances in the Food Packaging Production from Agri-Food Waste and By-Products: Market Trends for a Sustainable Development

Agricultural waste has been a prominent environmental concern due to its significant negative impact on the environment when it is incinerated, disposed of in landfills, or burned. These scenarios promoted innovations in the food packaging sector using renewable resources, namely agri-food waste and by-products such as bagasse, pulps, roots, shells, straws, and wastewater for the extraction and isolation of biopolymers that are later transformed into packaging materials such as bioplastics, biofilms, paper, and cardboards, among others. In this context, the circular bioeconomy (CBE) model is shown in the literature as a viable alternative for designing more sustainable production chains. Moreover, the biorefinery concept has been one of the main links between the agri-food chain and the food packaging industry. This review article aimed to compile recent advances in the food packaging field, presenting main industrial and scientific innovations, economic data, and the challenges the food packaging sector has faced in favor of sustainable development.

Biobased polymers are of great interest due to the release of tension on non-renewable petroleum-based polymers for environmental concerns. However, biobased polymers usually have poor mechanical and barrier properties when used as the main component of coatings and films, but they can be improved by adding nanoscale reinforcing agents (nanoparticles - NPs or fillers), thus forming nanocomposites. The nano-sized components have a larger surface area that favors the filler-matrix interactions and the resulting material yield. For example, natural fibers from renewable plants could be used to improve the mechanical strength of the biobased composites. In addition to the mechanical properties, the optical, thermal and barrier properties are mainly effective on the selection of type or the ratio of biobased components. Biobased nanocomposites are one of the best alternatives to conventional polymer composites due to their low density, transparency, better surface properties and biodegradability, even with low filler contents. In addition, these biomaterials are also incorporated into composite films as nano-sized bio-fillers for the reinforcement or as carriers of some bioactive compounds. Therefore, nanostructures may provide antimicrobial properties, oxygen scavenging ability, enzyme immobilization or act as a temperature or oxygen sensor. The promising result of biobased functional polymer nanocomposites is shelf life extension of foods, and continuous improvements will face the future challenges. This chapter will focus on biobased materials used in nanocomposite polymers with their functional properties for food packaging applications.
