Abstract The two distinct types of composite materials (5% to 10%) were developed using recycled polyvinyl alcohol fiber (RPA), silicon nitride fiber (SN), and reduced carbon nanoparticles (RCN). Enhanced microstructural properties and mechanical strength were attained through the application of the 3-glycidoxypropyltrimethoxysilane coupling method. The combination of the resin-like properties of RPA-SN fiber resulted in the formation of robust outer strength and a high bonding structure. RPA-RCN composite materials with a weight percentage of 10% exhibited a tensile strength of 42 MPa. In contrast, RPA-SN-RCN composite materials containing 5% to 10% demonstrated enhanced tensile, bending, and… More >

Abstract Concrete production often relies on natural aggregates, which can lead to resource depletion and environmental harm. In addition, improper disposal of thermoplastic waste exacerbates ecological problems. Although significant attention has recently been given to recycling various waste materials into concrete, studies specifically addressing thermoplastic recycled aggregates are still trending. This underscores the need to comprehensively review existing literature, identify research trends, and recognize gaps in understanding the mechanical performance of thermoplastic-based recycled aggregate concrete. Accordingly, this review summarizes recent investigations focused on the mechanical properties of thermoplastic-based recycled aggregate concrete, emphasizing aspects such as compressive… More >

Abstract With the rapid development of the Internet of Things (IoT), artificial intelligence, and big data, waste-sorting systems must balance high accuracy, low latency, and resource efficiency. This paper presents an edge-friendly intelligent waste-sorting system that integrates a lightweight visual neural network, a pentagonal-trajectory robotic arm, and IoT connectivity to meet the requirements of real-time response and high accuracy. A lightweight object detection model, YOLO-WasNet (You Only Look Once for Waste Sorting Network), is proposed to optimize performance on edge devices. YOLO-WasNet adopts a lightweight backbone, applies Spatial Pyramid Pooling-Fast (SPPF) and Convolutional Block Attention Module… More >

Abstract Industrial processes often involve rotating machinery that generates substantial kinetic energy, much of which remains untapped. Harvesting rotational kinetic energy offers a promising solution to reduce energy waste and improve energy efficiency in industrial applications. This research investigates the potential of electromagnetic induction for harvesting rotational kinetic energy from industrial machinery. A comparative study was conducted between disk and cylinder-shaped rotational bodies to evaluate their energy efficiency under various load conditions. Experimental results demonstrated that the disk body exhibited higher energy efficiency, primarily due to lower mechanical losses compared to the cylinder body. A power… More >

Abstract Saccharification of lignocellulosic wastes is the bottleneck of different bio-based chemical industries. Using enzymes for saccharification of lignocellulosic materials has several advantages over using chemicals. In the current work, the application of the Maximyze^® enzyme system, which is industrially used in papermaking, was investigated in the saccharification of paper sludge and fiber dust wastes from the tissue paper industry. For optimizing the saccharification process, the effects of the consistency %, enzyme loading, and incubation time were studied and optimized using the Response Surface Methodology. The effect of these factors on the weight loss of paper sludge… More > Graphic Abstract

Abstract Electrical energy can be harvested from the rotational kinetic energy of moving bodies, consisting of both mechanical and kinetic energy as a potential power source through electromagnetic induction, similar to wind energy applications. In industries, rotational bodies are commonly present in operations, yet this kinetic energy remains untapped. This research explores the energy generation characteristics of two rotational body types, disk-shaped and cylinder-shaped under specific experimental setups. The hardware setup included a direct current (DC) motor driver, power supply, DC generator, mechanical support, and load resistance, while the software setup involved automation testing tools and… More >

Abstract In laser powder bed fusion (LPBF), the unmelted powder recovered from the powder bed is degraded due to particle-laser interaction during continuous processing. The sensitivity of LPBF performance and molding quality to powder properties, waste powder is usually discarded after several molding cycles, which increases the cost of raw materials. At the same time, the low laser absorption rate and high thermal conductivity of copper and copper alloys inhibit the complete melting of copper powder prepared by LPBF. Therefore, it is challenging to fabricate copper alloy components with full high density and high conductivity through… More >

Abstract The textile industry generates large volumes of waste throughout its production process. Most of this waste is colored, therefore, discoloration is an important step toward recycling and reusing this waste. This study focused on the chemical reductive discoloration of textile waste composed of cotton dyed with reactive dye. The experimental design demonstrated the significant influence of the concentration of reducing agent and time of reaction on the degree of whiteness of the cotton fibers. The concentration of the alkaline agent was not significant in the process. The optimization of the reaction conditions lead to Berger… More > Graphic Abstract

Abstract The composition of paper cups creates a challenge for the recycling industry, as the paperboard–plastic film composite is hard to separate. Therefore, paper cups are sent to landfills or waste incinerators. This study explores the combined use of red worms (Eisenia fetida) and Greater wax moth (Galleria mellonella) in the biodegradation of paper cups. The study investigates the conditions and combinations that promote using Eisenia fetida and Galleria mellonella for degrading paper cups. The study considered the influence of environmental temperature, the presence of food waste, varying the number of Eisenia fetida worms, and the… More > Graphic Abstract
