In the context of the increasing global population and the resultant increase in the consumption of resources, one of the greatest challenges of our society is to produce innovative polymeric materials by valorization of the renewable resources in an attempt to diminish the dependency of European companies on petroleum-based plastics. Renewable residues, such as cereal biomass, fruits, medicinal and aromatic plants waste, natural proteins extracted from mammalian skin by-products together with bioadditives and nanoparticles, are among the most promising of the next generation of raw materials used for environmentally friendly applications, such as food packaging and medical devices.

The development and testing of these innovative materials will provide key insights into recent legislation on the management of waste worldwide as well as relevant case studies to illustrate the enormous potential of valorization of polymeric materials from renewable resources for a more sustainable society. Environmental impact and socio-economic analyses will allow the assessment of profitability and comparative advantages of the new materials under investigation leading to business opportunities for stakeholders.

This Special Issue covers the recent development of renewable resources valorization strategies for the sustainable production of polymeric-based biocomposites/bionanocomposites designed for various purposes. Topics of interest include the processing of polymers from renewable resources (melt processing, electrospinning, 3D printing, coating) for obtaining polymeric-based biocomposites with multifunctional properties (mechanical, thermal, biocompatibility, antioxidant or antimicrobial features) when compared to conventional materials, especially in terms of environmental friendliness. The aim of this Special Issue is to increase the knowledge of valorization of renewable resources by publishing the latest research information. Original research and review articles are welcome.

Potential topics include but are not limited to the following:

• Food waste valorization and polymeric materials from renewable resources
• Extract proteins valorization and polymeric materials from renewable resources
• Environmentally friendly modified polymeric-based biocomposites
• Green processing technologies and polymeric materials from renewable resources
• Edible food packaging and polymeric materials from renewable resources
• Advanced applications of polymeric biocomposites/bionanocomposites-based renewable resources
• Bio-based macromolecular products
• Life cycle assessment analysis and polymeric materials from renewable resources
