Special Issue Information

Dear Colleagues,

Worldwide, the perception of environmental concerns has caused the appearance of sustainable and eco-friendly green materials, which are renewable resource-based, recyclable, and biodegradable. The utilization of renewable and recycled resources decreases the demand for petrochemicals and minerals, thus preventing natural resource depletion. Commercial products, as well as their wide range of applications, are now being developed based on green composites. Green composites are considered the next generation of sustainable composite materials produced using natural/green materials in order to advance sustainability, eco-efficiency, and green chemistry, as these green materials garner considerable attention from academia and industry. Nowadays, green composites have been used in various applications including biomedical, energy, automobile, toys, sports, and so on. This Special Issue aims to present the latest progress in green composites’ fabrication, characterization, testing, and applications.

Designing a novel platform capable of providing a proper tissue regeneration environment is a key factor in tissue engineering. Herein, a green composite based on gelatin/agarose/zeolite with pomegranate peel extract was fabricated as an innovative platform for tissue engineering. Gelatin/agarose was loaded with pomegranate peel extract-loaded zeolite to evaluate its swelling behavior, porosity, release rate, and cell viability performance. The composite characteristics were evaluated using XRD and DSC. The hydrogel performance can be adjusted for the desired aim by zeolite content manipulation, such as controlled release. It was shown that the green nanocomposite exhibited proper cellular activity along with a controlled release rate. Moreover, the hydrogel composite’s swelling ratio was decreased by adding zeolite. This study suggested a fully natural composite as a potential biomaterial for tissue engineering, which opens new ways to design versatile hydrogels for the regeneration of damaged tissues. The hydrogel performance can be adjusted specifically by zeolite content manipulation for controlled release. Full article

Transformation of waste into resources is an important part of the circular economy. Nowadays, the recovery of materials in the most effective way is crucial for sustainable development. Composite materials offer great opportunities for product development and high performance in use, but their position in a circular economy system remains challenging, especially in terms of material recovery. Currently, the methods applied for recycling composites are not always effective. The aim of the article is to analyse the most important methods of material recovery from multilateral composites. The manuscript presents three case studies related to the recycling of products manufactured from composites: used tyres, wind turbine blades, and solar panels. It shows the advantages and disadvantages of currently applied methods for multilateral composite utilisation and presents further trends in composite recycling. The results show that increasing volumes of end-of-life composites have led to increased attention from government, industry, and academia. Full article
