The attention towards managing food waste (FW) and transforming it into compost has significantly increased in recent years, driven by the potential advantages it offers for sustainable agriculture and waste reduction. Biochar, a carbon-rich amendment derived from biomass through pyrolysis, has gained significant attention due to its potential benefits to enhance compost quality. This systematic review analyzed 11 studies to assess the role of biochar in optimizing FW composting. Studies revealed several benefits of biochar addition, including shortening of the time to reach the thermophilic stage and an increase in composting temperature. Biochar also improved compost quality by maintaining nitrogen content, reducing ammonia emissions, and promoting a favorable pH for microbial activities. Its porous structure created a suitable habitat for microbes, potentially accelerating organic matter degradation. Additionally, biochar's high cation exchange capacity (CEC) helped immobilize potentially toxic metals, reducing their availability in the final compost. However, our knowledge of biochar's benefits in improving compost quality remains incomplete. The reviewed studies neglected to evaluate the microbial quality of the resulting compost and the cost-effectiveness of biochar application. Future research should prioritize long-term studies to assess plant uptake from soils amended with biochar. Additionally, investigations into the optimal biochar-to-compost ratio, as well as the most effective timing and methods for land application, should be undertaken. Addressing these knowledge gaps is crucial for optimizing the utilization of biochar in FW composting, thereby leading to sustainable waste management practices and enhanced soil fertility.

Studies on structural health monitoring of timber bridges are limited. The unique characteristics of timber, such as anisotropy, hygroscopicity, and high variability under climate changes, necessitate the customization of a structural health monitoring system for each specific configuration. This paper provides a thorough examination of the existing methodologies for structural health monitoring of timber bridges, including the timber bridge deterioration mechanism, the practical non-destructive testing techniques, potential future advancements such as artificial intelligence, digital twin, and sensor/data fusion and Internet of Things in the application of structural health monitoring to timber bridges. Structural health monitoring of timber bridges has received less attention than monitoring of bridges manufactured from other materials such as steel or concrete. More specifically, most studies have been conducted on monitoring moisture, temperature, structural performance, and vibration behavior under the loads in timber bridges. However, these studies have not investigated the correlation between the factors that affected the structural performance of timber bridges. Also, studies related to data-driven and artificial intelligence methods applied to timber bridges are limited. Therefore, the current study is about structural health monitoring of timber bridges by focusing on deterioration mechanisms of timber, non-destructive tools for damage detection, and discussion about emerging approaches, including artificial intelligence tools, sensor/data fusion and Internet of Things, and digital twin.

Monitoring and management engineering technologies, as well as crude oil production, have recently advanced significantly. Technology advancements aside, monitoring, administration, wait times, and emergency response remain quite poor, especially for the crude oil production cycle, where real-time management and monitoring are difficult. Several methodologies and technologies utilized for continuously monitoring and managing crude oil manufacturing are analyzed in light of the integrating of the Industrial Internet of Things (IIoT) and Edge Computing (EC). The ultimate objective is to monitor and manage the whole value chain process to increase production dependability and availability and generate better economic products and services. This study goes over crude oil production guidelines and unresolved research difficulties. The IIOT and EC integration are viewed as a possible approach for establishing domestic services and corporate procedures for increasing crude oil production. One hundred eighty-eight relevant studies published between 2017 and 2023 were indexed in the WOS (Web of Science), SCOPUS, OnePetro, and IEEE Xplore databases. A survey based on a literature review showed 50 studies (selected from those studies through the literature review stages) and their architectures and frameworks to automate crude production to better monitor alerts and production control. This survey aims to provide a comprehensive overview of multiple studies to highlight the deficiencies in recent research and serve as a reference for subsequent endeavors to develop solutions for a straightforward process monitoring system. Such a system would empower process operators to promptly and effortlessly detect any sources of abnormality within the process.

The largest challenges to the globe are energy scarcity, freshwater shortages, and global warming are the world's largest challenges. Fossil fuels harm the environment and intensify global warming. Solar distillation technology will replace fossil fuels sooner or later, as it produces freshwater without polluting the environment or being expensive. The distillation structure only requires exposure to the sun's rays. Solar achieving the best freshwater production with the greatest thermal energy performance and the lowest cost, solar distillers (SD) have recently experienced a number of designs. These include the stepped SD, double-slope SD, inclined SD, and pyramid SD. Most of the time, nanofluids, phase change materials (PCMs), wick materials, reflectors, organic fluids, corrugated absorber plates, flat SDs, bi-layered structures, heat localization, hybrid systems, SD with solar heaters, energy storage materials, porous absorbers, and cover cooling are used to change SDs. This essay evaluates and discusses the detailed examination of the wick type materials in solar stills with several configurations, considering the wick type floating, spinning, inclined, and corrugated. To make these materials more suitable for use in a range of applications to produce clean water, different recommendations are made. There have been many improvements, resulting in enhanced productivity rates, according to a literature review. Depending on design, geography, and accessory selection, Wicks technology increased distillers' productivity by 20%–30 %. Additionally, combining this technology with other technologies like PCMs and nanomaterials can achieve high productivity.

This review discusses the opportunities and challenges of 3D printing using clay and natural fibers with a focus on wood sawdust in direct ink writing (DIW) method. Using earthen and natural materials promotes sustainable and affordable construction. Additive manufacturing also offers low-cost and fast construction and facilitates the transition towards automated and customized practices. Considerations in preparing print slurry using clay and sawdust/natural fiber are presented. The key rheological tests and criteria to assess the printability and characteristics of fresh printing slurry are discussed. Printability of fresh slurry is explained with a focus on flowability, extrudability, and buildability. Additionally, the mechanical properties of 3D-printed clay composites reinforced with natural fibers are reviewed. The review shows the complex role of using wood sawdust and natural fiber in clay 3D printing. While such an addition may compromise the strength properties of clay composite, it improves the shrinkage and cracks following print task. The study concludes that post-printing performance shall be linked to proper design of print slurry via rheological characterization techniques. Further research is required to establish the fresh ink printability criteria. These criteria should account for rheology of fresh slurry, different loading scenarios of in-service printed structure, and geometrical complexities and requirements of final product. To fully leverage the power of 3D printing in customized fabrication and construction, additive manufacturing can be practiced by focusing on aesthetic and architectural design. Clay 3D printing can also be integrated with computational design to fabricate building structures with exterior (façade) and/or interior applications.

MXene-based supercapacitors utilize symmetric or asymmetric electrodes. Symmetric electrodes use the same MXene material for positive/negative electrodes, providing balanced performance and stability. Asymmetric electrodes incorporate different MXene materials or combine MXene with other substances to enhance energy density (ED), stability, specific capacitance (SC), and power density (PD). The symmetric and asymmetric configurations make MXene-based supercapacitors versatile for various applications. In this review, we have summarized MXene-based supercapacitors using symmetric and asymmetric electrode materials. A comparative study has been done on the surface modification of the MXene-based supercapacitor electrodes using doping, polymer decorations, anchoring of nickel materials, and coupled carbon nanomaterials methods. The discoveries from this research serve as an invaluable reference for upcoming researchers, contributing to their comprehension of the performance and potential applications of MXene electrodes of supercapacitor technology.

The evolution of advanced engineering materials and high-speed cutting techniques has emphasized the critical role of cutting fluids (CFs) in machining processes to meet sustainability requirements. Cutting fluids application offers several key benefits, including temperature reduction during cutting, decreased friction between the workpiece/chip and tool, extended tool lifespan, enhanced machining efficiency, and boosted surface finish. These positive outcomes are primarily attributed to the core functions of cutting fluid, namely lubrication, cooling, cleaning, and corrosion protection. However, they have serious disadvantages such as posing risks to ecosystems and human health as well as high disposal costs. Despite these disadvantages, ongoing research and development efforts are focused on improving the environmental sustainability, health and safety, and performance of metal cutting fluids through the use of green biodegradable oils, developing advanced recycling technologies, and the use of efficient application methods such as high-pressure cooling and minimum quantity lubrication (MQL). This review paper sheds light on sustainable machining technologies that are utilized to minimize the environmental impacts of conventional cutting fluids. Different types of CFs including their benefits and role in cutting operations are also introduced. Finally, sustainable assessment including economical, environmental, and social aspects of green machining technologies is discussed.
