Special Issue Information

Dear Colleagues,

Polymeric materials, more commonly known as plastics, are versatile materials that offer specific solutions for applications in various sectors, such as packaging, construction, automotive, electronics, sports, agriculture and medicine. These materials, due to their attractive and interesting properties such as light weight, durability, easy workability, low cost and good thermo-mechanical properties, are produced in large volumes. However, there are still some limits that absolutely must be eliminated, such as waste abandonment and end-of-life treatment, for a circular and efficient economy. Overcoming this challenge would also allow plastics to act in realizing a more sustainable future.

Food packaging, represents the largest field of application of plastics and it is responsible for the highest production of waste as most of these are single use plastics. Even if reuse or recycling are the preferred options, they are not always possible, especially when the packaging is dedicated to food, due to contamination risks. Therefore, the development of new eco-friendly biopolymer-based materials, such as biodegradable and/or bio-based and/or edible films, is strongly encouraged, for an environmentally sustainable development. In addition, the COVID-19 pandemic has generated changes in human consumption patterns, as a result of rigid public policies that have affected all socioeconomic sectors, causing an increase in the generation of plastic waste and incorrect disposal of them, transforming the crisis in the health sector into an economic, social and environmental threat. In this way, the dependence on disposable plastic products was evidenced, as well as the fragility of the waste management system and reduction of these materials, which is extremely important, mainly due to its long-term repercussions in a post-pandemic world. Therefore, now more than ever, it is necessary to develop new technologies that can mitigate the use of plastics, especially those derived from non-renewable sources (petroleum). Eco-friendly materials can represent a valid alternative as they can at the same time satisfy the requirements of biodegradability, biocompatibility with the environment in which they are disposed of and the release of non-toxic degradation products, also avoiding the dependence from non-renewable sources. 

This special issue will give academia and industry the opportunity to present an overview of new sustainable materials. The main goal of this Special Issue will be to collect recent progress in the preparation of eco-friendly materials for potential applications including but not limited to food, packaging, biomedical and engineering. The themed research topic is expected to provide more awareness of the use of such materials in innumerable aspects of our daily routine.

Research areas may include (but not limited to) the following: research papers, review, case study, short-note.

We look forward to receiving your contributions.

Currently, from the sustainable development point of view, edible films are used as potential substitutes for plastics in food packaging, but their properties still have limitations and require further improvement. In this work, novel edible carrageenan films reinforced with starch granules and nanocellulose were developed and investigated for application as a bio-based food packaging system. The nanocellulose was used to improve film mechanical properties. Aloe vera gel was incorporated for antibacterial properties. Glycerol and sesame oil were added as plasticizers into the nanocomposite film to improve flexibility and moisture resistance. The interactions between charged polysaccharide functional groups were confirmed by FTIR spectroscopy. The migration of starch particles on the upper film surface resulting in increased surface roughness was demonstrated by scanning electron and atomic force microscopy methods. Thermogravimetric analysis showed that all films were stable up to 200 °C. The increase in nanocellulose content in films offered improved mechanical properties and surface hydrophilicity (confirmed by measurements of contact angle and mechanical properties). The film with a carrageenan/starch ratio of 1.5:1, 2.5 mL of nanocellulose and 0.5 mL of glycerol was chosen as the optimal. It demonstrated water vapor permeability of 6.4 × 10−10 g/(s m Pa), oil permeability of 2%, water solubility of 42%, and moisture absorption of 29%. This film is promising as a biodegradable edible food packaging material for fruits and vegetables to avoid plastic. Full article

This manuscript concerned customer recognition of biodegradable packaging. The authors of this study took up this issue due to its topicality and importance for enterprises and customers. The authors conducted a survey among consumers that showed how customers perceived 100% biodegradable packaging. It explored the role of these packages in marketing activities in the organic products market. The purpose of this article was to determine customer awareness of 100% biodegradable packaging. A diagnostic survey with a sample of 1000 respondents was used. The survey results indicated that customers declared environmentally friendly attitudes; however, they were not always able to recognize biodegradable packaging. Providing correct answers on this topic did not depend on gender, health status, or place of residence, only on the age and education of respondents. The research results may have both practical and theoretical implications. The results contribute to the development of management sciences. The conclusions from the manuscript allow producers, not only in food, to design new, biodegradable packaging in accordance with the feelings and expectations of consumers. Thus, it can contribute to increasing the demand for products in ecological packaging. Full article
