Abstract This study aimed to produce and characterize mycelium leather (Mylea) derived from oil palm empty fruit bunch (OPEFB). Variations in OPEFB composition (10%, 20%, 30%, and 40%) were tested using a 10% w/w Ganoderma lucidum inoculum. The mycelium underwent boiling, plasticization, drying, pressing, waxing, and Tencel fabric reinforcement to form Mylea. The physical, mechanical, and flammability properties of OPEFB-based Mylea were evaluated as a potential animal leather substitute. The highest tensile strength (8.47 MPa) was observed in the 0% OPEFB sample due to reinforcement with the Tencel fabric layer. Meanwhile, the 20% OPEFB sample after drying More > Graphic Abstract

Abstract This study explores vegan leather, an eco-friendly substitute for conventional animal-derived leather. Using materials like polyurethane, pineapple leaves, cork, and recycled plastics, vegan leather aims to transform the fashion industry and consumer products while addressing environmental concerns. Despite its advantages, challenges related to availability and durability persist. The booming market for vegan leather is expected to reach billions of dollars, reflecting a broader societal shift towards sustainable and cruelty-free alternatives. The review traces the historical development of vegan leather from its origins in Germany to modern innovations like Mylo and Piñatex. By comparing these materials More >

Abstract Leather manufacturing process involves a lot of waste disposal which pollutes environment, some of the processes are inevitable. In the present investigation, 3D printing technology was used to reduce the wastage and to cover defective regions in leather. The present study focuses on synthesis of acrylic binder using emulsion polymerization technique. These binders were analysed for solid content for better optimisation of the amount of binder to be utilised for finishing operation. The experimental binder was prepared with 26% solids. Particle size and thermogravimetric analyses were carried out to understand the size and shape of… More >

Abstract Taking an industrial sludge and its preparation of sludge wrap shell aggregates (WSAs) instead of sand to prepare baking-free brick as the research object, the development law of mechanical properties and the influence mechanism of macro and micro characteristic parameters of the bricks under different sludge and WSAs replacement rates were studied through the macroscopic mechanical properties test, with the help of nuclear magnetic resonance (NMR), transmission electron microscopy-energy spectrum and other testing technology and pores and cracks analysis system (PCAS) software. The results showed that the compressive strength of each sample decreased with the… More > Graphic Abstract

Abstract Collagen powder hydrolysates were reacted with a solution of commercial mimosa bark tannin extract. The mixture was prepared at ambient temperature and prepared at 80°C to determine what reactions, if any, did occur between the collagen protein through its amino acids and the polyphenolic condensed tannin. The reaction products obtained were analyzed by matrix assisted laser desorption ionization time-of-flight (MALDI ToF) mass spectrometry. Reactions between the two materials did appear to occur, with the formation of a relatively small proportion of covalent and ionic linkages at ambient temperature but a considerable proportion of covalent linkages… More >

Abstract Based on a novel triazine compound, the properties of tanned leather and commercial feasibility in pilot scale have been investigated. Then this novel approach tanning was compared with conventional chrome tanning: in the condition of less-salt pickling and chrome free, the physicochemical properties including thermal stability and mechanical strength were analyzed. Meanwhile, the surface roughness and fiber dispersion were evaluated as well. The results show that the thermal stability and mechanical strength of the triazine compound tanned leather are similar to conventional chrome tanned leather, the fiber bundle is well-dispersed and much evener than that More >
