Summary

The Journal of Renewable Materials (JRM) is born ten years ago, and 10 years for a new journal is a date to celebrate. This is the reason why such Special Issue has been created, both to celebrate past achievements but mainly to look confidently to the future achievements which will not fail to come. These past 10 years have been rich of growth in several fields of both Materials Science and Environmental Science for our journal and they have seen the growth of the journal to increase incredibly with a variety of renewable and recyclable materials and their applications being addressed and published. The variety of materials and applications has been really incredible, attesting for the present day liveliness of the “renewables” field. The JRM has then grown and continues growing both in citations to the research work presented in it, confirming its importance in its chosen “Renewables” area, as well as growing in reputation within the scientific community it serves.

 

The reason for launching such a wide-ranging Special Issue is to encourage all scientists involved in renewable materials to have a showcase for the multitude of different aspects of renewable materials, namely renewable biomaterials of any kind used for:

 

1. Biomaterials for construction

2. High–tech biomaterials of any kind

3. Biomaterials for pharmaceutical/medical applications

4. Biocomposites and biofibres of any kind

5. Bioadhesives, bioresins, biopolymers and bioplastics

6. Electronics from renewable biomaterials

7. Biomaterials substitutes for any synthetic material in any application

8. Chemicals from renewable biomaterials

9. Recyclables from renewables

 

And so many other areas, the list being so long that is almost impossible to define the multitude of fields which are of interest for this issue. Dear colleagues and friends, let’s go for it, let’s make this a memorable special issue to showcase all what renewable can do.

    Abstract Chitosan films with propolis aqueous extract were obtained in order to improve the antioxidant capacity of the materials. Likewise, oleic acid (OA) was also incorporated to enhance the film hydrophobicity, with and without previous infusion with propolis, to extract other potentially active compounds. The propolis extracts and the chitosan film-forming dispersions were characterised as to their particle size distribution, zeta potential and rheological behaviour. Chitosan-based films with aqueous extract and with oleic acid, containing or not propolis compounds, were obtained and characterised as to their microstructure, mechanical, barrier and optical properties and antioxidant capacity in… More >

    Abstract The escalating demand for energy coupled with environmental concerns necessitates exploring sustainable alternatives to fossil fuels. The study explores the viability of using large ocean-based seaweeds as a source of third-generation biomass, specifically focusing on their conversion to biofuel via the process of pyrolysis. Sargassum plagiophyllum and Ulva lactuca represent prevalent forms of macroalgae, posing significant discharge challenges for coastal regions globally. However, the exploration of their potential for bio-oil generation via pyrolysis remains limited. This study investigates the pyrolysis process of S. plagiophyllum and U. lactuca for biofuel production, aiming to provide valuable insights into their utilization and… More >

    Abstract The present work emphasizes the isolation of cellulose nanofiber (CNF) from the kenaf (Hibiscus cannabinus) bast through a chemo-mechanical process. In order to develop high CNF yield with superior properties of CNF for improving compatibility in varied applications this method is proposed. The fiber purification involved pulping and bleaching treatments, whereas mechanical treatment was performed by grinding and high-pressure treatments. The kraft pulping as a delignification method followed by bleaching has successfully removed almost 99% lignin in the fiber with high pulp yield and delignification selectivity. The morphology of the fibers was characterized by scanning electron More >

    Abstract Biomass has become of recent interest as a raw material for ‘green’ graphenic carbon (GC) since it promotes an environmentally friendly approach. Here, we investigate a single pyrolysis route to synthesize GC from coconut shells which provides a simple method and can produce a high yield, thus being convenient for large-scale production. The pyrolysis involves a stepped holding process at 350°C for 1 h and at 650°C or 900°C for 3 h. The GC sample resulted at the 900°C pyrolysis has a thinner sheet, a less porous structure, a higher C/O ratio, and an enhanced More >

    Abstract In this research, activated carbon from mangosteen peel has been synthesized using sulfuric acid as an activator. The adsorption performance of the activated carbon was optimized using malachite green dye as absorbate. Malachite green dye waste is a toxic and non-biodegradable material that damages the environment. Optimization of adsorption processes was carried out using Response Surface Methodology (RSM) with a Box-Behnken Design (BBD). The synthesized activated carbon was characterized using FTIR and SEM instruments. The FTIR spectra confirmed the presence of a sulfonate group (-SOH) in the activated carbon, indicating that the activation process using… More >

    Abstract In recent decades, the ozone layer has suffered considerable damage, increasing the entry of ultraviolet (UV) light into the atmosphere and reaching the earth’s surface, negatively affecting life. Accordingly, researchers aimed to solve this problem by synthesizing advanced UV-shielding materials. On the other hand, developing an easy and green strategy to prepare functional materials with outstanding properties based on naturally abundant and environmentally friendly raw materials is highly desirable for sustainable development. Because biomass-derived materials are sustainable and biodegradable, they present a promising substitute for petroleum-based polymers. The three main structural constituents of the plant More >

    Abstract This study is the first to evaluate the phytochemical content and biological properties of Tunisian T. platyphyllos Scop. A total of 23 compounds of essential oils were identified by gas chromatography-mass spectrometry (GC-MS) analysis of bracts and fruit extracts. The results show that oxygenated monoterpenes were the dominant class of essential oils. The phenolic composition was investigated by matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF). The analysis showed that the chemical profiles of the ethanolic extracts of bracts and fruits are substantially similar. The highest polyphenol content was found in the ethanolic extracts of the fruits (7.65… More >

    Abstract The huge volumes of crop residues generated during the production, processing, and consumption of farm products constitute an ecological nuisance when ineffectively managed. The conversion of crop residues to green hydrogen is one of the sustainable management strategies for ubiquitous crop residues. Production of green hydrogen from crop residue sources will contribute to deepening access to clean and affordable energy, mitigating climate change, and ensuring environmental sustainability. However, the deployment of conventional thermochemical technologies for the conversion of crop residues to green hydrogen is costly, requires long residence time, produces low-quality products, and therefore needs… More >

    Abstract This study aimed to investigate the water absorption capacity of thermally modified and non-modified spruce and blue-stained spruce wood. The wettability of wood depends on various factors, including its type, density, porosity, and surface treatment. Wood can swell and become distorted when exposed to water or humidity, impacting its structural integrity. Hence, it is crucial to consider the water and water vapour uptake in the wood when choosing materials for applications that are likely to be exposed to moisture. Various moisture absorption tests were conducted to assess water absorption capacity, including short-term and long-term water… More >
