Summary: Earthworks in man-made facilities can cause erosion on slopes, but using geotextiles made from reclaimed fibers can prevent degradation and facilitate reclamation. This study examined the mechanical and chemical properties of geotextiles and found that they promote plant growth and enhance the colonization process on slopes.

Summary: The textile industry contributes to about 5% of global waste, with 20 billion pounds of waste landfilled annually. Advanced recycling methods are needed in the context of the circular economy. Chemical recycling is more common and produces materials with better quality compared to physical recycling. The article also discusses intelligent wearables and advanced textile processing technologies.

Summary: The leather industry generates a significant amount of solid waste. Various methods have been developed to recover and utilize these wastes, primarily by extracting collagen using chemical methods. However, the poor quality of extracted collagen limits its applications, mostly as a nitrogen source ingredient in fertilizers. This study presents a new process based on enzymatic hydrolysis to extract collagen from tanned leather solid wastes for use as a filling agent in low quality leather. The extracted collagen retains its integrity and quality due to the enzymatic hydrolysis. Additionally, an enzymatic cross-linking reaction between collagen and casein was developed to enhance the filling effect. The results suggest the potential of extracted collagen to be employed in leather processing as both an additive and a substitutive filler.

Summary: Poly(ethylene terephthalate) is widely used polymer due to its excellent properties, but the disposal of PET waste is a global environmental issue. Chemical recycling using Sn-doped ZnO catalyst has been studied for complete depolymerization of PET waste. The catalytic activity was evaluated by synthesizing Sn-doped ZnO nanoparticles and testing the aminolysis depolymerization. The results showed that higher doping percentages of Sn led to increased yield of depolymerized product BHETA.

Summary: Leather industries contribute to soil pollution, particularly through the disposal of leather wastes containing chromium. This study successfully extracted chromium from leather wastes and developed an aluminum-based composite material using the extracted chromium. After ball milling, the density of the composite material decreased, but the distribution of reinforcement particles improved. The composite material, consisting of 5% ball-milled collagen powder and 5% alumina particles, exhibited enhanced tensile strength and hardness, while reducing ductility and toughness. The corrosion weight loss and thermal expansion of the composite material were measured, and the X-Ray diffraction analysis revealed the presence of various phases. The developed composite material shows potential for applications in engine components.

Summary: India is a major leather-producing country and possesses a large amount of leather solid wastes, which are not effectively utilized. These wastes contain protein and lipids that can be used as feedstock for biofuel production. This review article demonstrates that there is significant bioenergy potential for using leather solid wastes as a green fuel. The biofuel potential includes biogas, biodiesel, bio-oil, and bio-char. Factors that affect the efficacy of the biofuel process should be considered when establishing a biofuel recovery plant. The utilization of leather solid wastes for biofuel production not only brings economic benefits, but also has positive environmental impacts.

Summary: The leather industry is facing two opposite paths: one towards cleaner production methods driven by legislative trends for eco-sustainability, and the other towards competitiveness improvement through the development of innovative and high-quality products in response to the rise of alternative materials. Leather finishing, a crucial phase in leather production, requires the use of polluting chemical products. This research aims to develop an eco-sustainable finishing formulation that meets market requirements by utilizing collagen extracted from tanned wastes and cross-linking it to the leather surface. The developed bio-based leather finish exhibits the same quality standards as resin-based finishes.

Summary: This study demonstrates the production of kombucha-derived bacterial cellulose (KBC) from different modified kombucha and diverse bio-waste sources using Komagataeibacter xylinus for cost-effective industrial scalability. The KBC synthesized with sour whey and whey/apple juice/brewer's spent grains mixture media showed superior production yields and could potentially be used as a leather substitute.

Summary: The study aimed to reduce composite porosity, decrease flammability, and improve mechanical properties of natural fibre products by chemically modifying roving and fabric with silanization and flame retardant treatment. Various types of silanes and flame retardant compounds were utilized, along with testing methods such as microcalorimeter and X-ray tomography to evaluate the modifications. By combining flame retardancy and enhanced fibre impregnation, promising results were achieved in optimizing modifications in fibre and matrix.
