Abstract Bamboo parenchymal cells (PCs) represent an underutilized resource with significant potential as a sustainable and versatile bio-based material. Despite the extensive research on bamboo fibers, PCs, comprising a considerable portion of bamboo, have been largely overlooked. This review examines the multi-scale structure of bamboo PCs, including their microcapsules, multi-wall layers, and pits, which provide the structural foundation for diverse applications. Various physical and chemical isolation methods, impacting the properties of extracted PCs, are also discussed. Notably, the review explores the promising applications of bamboo PCs, highlighting their use as filler materials in formaldehyde-free composites, as More > Graphic Abstract

Abstract In this study, the casting process is used to fabricate modified polyvinyl alcohol (PVA), starch (S), and carboxymethyl cellulose (CMC) polymer blend films (PVA/S/CMC) loaded with various concentrations of iron-doped carbon quantum dots (Fe-CQDs) and denoted as (PVA/S/CMC@Fe-CQDs). A one-step microwave strategy was employed as a facile method to prepare Fe-CQDs. Through a series of characterization techniques, fourier-transform infrared (FTIR) spectroscopy, x-ray diffraction (XRD) analysis, and scanning electron microscopy (SEM) have been used to show the successful integration of Fe-CQDs into the PVA/S/CMC matrix. Loading the synthesized Fe-CQDs to the polymeric matrix significantly enhanced the… More > Graphic Abstract

Abstract The development of actuators based on ionic polymers as soft robotics, artificial muscles, and sensors is currently considered one of the most urgent topics. They are lightweight materials, in addition to their high efficiency, and they can be controlled by a low power source. Nevertheless, the most popular ionic polymers are derived from fossil-based resources. Hence, it is now deemed crucial to produce these actuators using sustainable materials. In this review, the use of ionic polymeric materials as actuators is reviewed through the emphasis on their role in the domain of renewable materials. The review… More > Graphic Abstract

Abstract The article presents the results of a study on the possibility of synthesizing biodegradable poly(3-hydroxybutyrate-co-4-hydroxybutyrate) [P(3HB-co-4HB)] from renewable waste fish oil (WFO) by the Cupriavidus necator B-10646 bacterium. For the first time, waste oil generated during the processing of Sprattus balticus in the production of sprats was used as the main carbon substrate for the synthesis of P(3HB-co-4HB), and ε-caprolactone was used as a precursor instead of the more expensive γ-butyrolactone. Samples of P(3HB-co-4HB) with a 4HB monomer content from 7.4 to 11.6 mol.% were synthesized, and values of the bacterial biomass yield and the total yield of the… More > Graphic Abstract

Abstract The accumulation of non-biodegradable plastic debris in the environment raises serious concerns about potential long-term effects on the environment, the economy, and waste management. To assess the feasibility of substituting commercial plastics for a biodegradable renewable polymer for many applications, low-density polyethylene (LDPE) was mixed with varying concentrations of algal biomass (AB). Algae are considered a clean, renewable energy source because they don’t harm the environment and can be used to create bioplastics. Algal biomass grown in a high rate algal pond (HRAP) used for wastewater treatment used at 12.5–50 weight percent. Mechanical, thermal,… More > Graphic Abstract

Abstract The increasing severity of air pollution necessitates more effective and sustained air filtration technology. Concurrently, the desire for more environmentally friendly, sustainable materials with better filtering performance and less environmental impact drives the move away from conventional synthetic membranes. This review presents lignocellulosic biocomposite (LigBioComp) membranes as an alternative to traditional synthetic membranes. It focuses on their materials, fabrication, and functionalization techniques while exploring challenges and proposing methods for resourceful utilization. Renowned for their abundance and renewable nature, lignocellulosic materials consist of cellulose, hemicellulose, and lignin. Various applications can benefit from their antibacterial properties,… More > Graphic Abstract

Abstract This review is composed of three main parts each of which is written by well-known top specialists that have been, in a way or other, also the main participants of the majority of the developments reported. Thus, after a general part covering the grand lines and more in-depth views of more recent tannin, lignin, carbohydrate and soy bioadhesives, some mix of the other bio raw materials with soy protein and soy flour and some other differently sourced bioadhesives for wood, this review presents a more in-depth part on starch-based wood adhesives and a more in-depth… More > Graphic Abstract

Abstract This article aims to present the feasibility of storing thermal energy in buildings for solar water heating while maintaining the comfort environment for residential buildings. Our contribution is the creation of insulating composite panels made of bio-based phase change materials (bio-PCM is all from coconut oil), cement and renewable materials (treated wood fiber and organic clay). The inclusion of wood fibers improved the thermal properties; a simple 2% increase of wood fiber decreased the heat conductivity by approximately 23.42%. The issues of bio-PCM leakage in the cement mortar and a roughly 56.5% reduction in thermal… More > Graphic Abstract

Abstract Globally, fossil fuel dependence has created several environmental challenges and climate change. Hence, creating other alternative renewable and ecologically friendly bio-energy sources is necessary. Lignocellulosic biomass has gained significant attention recently as a renewable material for biofuel production. The large amounts of plantain and banana plant parts wasted after harvesting, as well as the peels generated daily by the fruit market and industries, demonstrate the potential of bioenergy resources. This review briefly assesses plantain and banana plant biomass (PBB) generated in the developing, developed, and underdeveloped countries, the consumable parts, and feasible products yield.
