Article
Full-text available
Plastics play a vital role in modern society but their non-biodegradable nature has led to environmental concerns. Biomass-derived biodegradable bioplastics offer an eco-friendly alternative and protein and starch-based bio-plastics, sourced from agro-food residues, are gaining prominence due to their renewability. However, many bio-based materials...

Full-text available
Conventional plastics pose environmental threats due to their non-biodegradable nature and their reliability on fossil resources, leading to the exploration of sustainable alternatives. In this sense, biodegradable bioplastics derived from renewable resources offer a promising solution to mitigate ecological impacts. This study focuses on the combi...
Article
Full-text available
The high production rate of fossil-based plastics, coupled with their accumulation and low degradability, is causing severe environmental problems. As a result, there is a growing interest in the use of renewable and natural sources in the polymer industry. Specifically, rice bran is a highly abundant by-product of the agro-food industry, with vari...

Chitosan (CH) is a very well-known biopolymer that has been widely used for the development of biomaterials with a wide range of applications in the biomedical field, such as the preparation of hydrogels, owing to its outstanding anti-inflammatory, antibacterial and antifungal properties, biocompatibility and biodegradability, although they present...

Article
Full-text available
Rice bran is an underutilized by-product of rice production, containing proteins, lipids and carbohydrates (mainly starches). Proteins and starches have been previously used to produce rice bran-based bioplastics, providing a high-added-value by-product, while contributing to the development of biobased, biodegradable bioplastics. However, rice bra...
Article
Full-text available
The manufacture of eco-friendly bioplastic materials from renewable resources to replace petroleum-based plastics has attracted increasing attention. For many years, proteins, lipids and polysaccharides have been proposed as natural biopolymers sources to obtain biodegradable plastic materials. As by-product from the rice industry, rice bran, is an...
Article
The agro-food industry produces huge amounts of wastes and by-products with high levels of carbohydrates and proteins, basic food groups that, properly treated, can be employed for the development of bioplastics. These high added-value products represent an alternative to traditional polymers. In this research work, rice bran was mixed with glycero...

The regeneration of soft tissues that connect, support or surround other tissues is of great interest. In this sense, hydrogels have great potential as scaffolds for their regeneration. Among the different raw materials, chitosan stands out for being highly biocompatible, which, together with its biodegradability and structure, makes it a great alt...
Article
Full-text available
The nature of the plasticizer fraction within a bioplastic matrix is of extreme importance. Thus, brittleness has sometimes been observed when water has been used. The goal of the present manuscript has been to assess the effects of the addition of sucrose and trehalose in gluten-based bioplastics either in presence or absence of water. It was foun...
Article
Millions of tons of malt sprouts, a low added-value by-product of the brewing industry, are produced after barley malting (germination of sprouting). Their valorisation can rise from their use for the development of bioplastics whose main source can be found in different wastes and by-products of the food industry, being an abundant, inexpensive an...

The high production rate of conventional plastics and their low degradability result in severe environmental problems, such as plastic accumulation and some other related consequences. One alternative to these materials is the production of oil-free bioplastics, based on wastes from the agro-food industry, which are biodegradable. Not only is rice...
Article
The present study addresses the immobilization of the GOX enzyme into a conventional polyvinyl alcohol (PVOH) membrane and a multi-layer membrane system (PCL/PVOH/PCL), both synthetized through electrospinning technique. More specifically, the enzyme was encapsulated inside a PVOH hydrophilic membrane, which was in turn protected by two hydrophobic...
Article
The development of green nanotechnology is generating research interest in the ecological biosynthesis of nanoparticles (NPs). In this study, the biosynthesis of stable iron nanoparticles was carried out using Phoenix dactylifera L. extract which is able to reduce iron ions to iron nanoparticles. The process comprises maceration extraction overnigh...
Article
The excessive use of fertilizers in horticulture applications generates subsoil and groundwater contamination due to their high solubility. A possible solution to this problem is the incorporation of nutrients in biodegradable matrices, allowing nutrients to be released in a controlled manner depending on the needs of the crops. The principal objec...
Article
Full-text available
Nowadays, biodegradable protein‐based matrices capable of storing micronutrients and releasing them in a controlled manner are being studied in order to avoid an excessive use of fertilizers. One of the methods to add micronutrients into matrices is through an immersion stage in a saturated solution, which provides matrices with high superficial co...
