To keep up with the rate of growth and global demand, it is necessary to manufacture products with high performance and improved durability. Wood-plastic composites (WPCs) are a rapidly growing class of construction materials formed by mixing wood fibers with a polymer matrix at a high temperature. However, significant technical issues remain, such as low thermal resistance, low water resistance, and limited interfacial contact or compatibility between wood fiber and the polymer matrix, which results in poor adhesion of the wood particles, etc. The structure and properties of the matrix/fiber interface can indeed have an impact on the final properties of the composites. To this end, good interfacial adhesion improves stress transmission from the matrix to the fiber, as well as composite performance. Therefore, chemical modification has been the most effective way to chemically bond the matrix to the filler. in this study, the modification is achieved by using maleic anhydride as a coupling agent which promotes the formation of chemical or material bonds between the wood flour (WF) and the polymer matrix. Three WF/high-density polyethylene (HDPE) composite blends with WF contents of 40%, 50%, and 60% were evaluated for density, flexural properties, hardness test, and thermal analysis. Physical tests showed that increasing the wood content of the composite from 40% to 60% increases the density and hardness of the WPC from 1,047 g/cm3 to 1,097 g/cm3 and from 64.5 to 67.7 respectively. On the other hand, increasing the wood flour content to 60% decreases the flexural strength from 37.524 mPa to 27.512 mPa, while the flexural modulus increases from 2176.125 mPa to 3568.284 mPa. in general, the results indicate that the developed WF/HDPE has suitable mechanical and thermal properties for outdoor applications. © 2022

The industrial sector accounts for a significant share of global energy consumption and CO 2 emissions, with steam systems playing a critical role in process heating and power generation. This paper presents a comparative analysis of three case studies conducted in morocco's pulp and paper, agri-food, and plastic industries, all of which are considered energy-intensive sectors. The objective is to assess the performance of these industries' steam systems using the steam system scoping Tool (sssT) and evaluate their system efficiencies. The study highlights energy-saving actions implemented in each case and demonstrates how simple maintenance measures, such as repairing steam leaks, controlling excess air, and improving insulation, can significantly enhance energy efficiency and reduce costs. By adopting a systems approach to steam optimization, the study proves that cost-effective actions with short payback periods can lead to substantial energy savings without requiring major capital investments. The annual cumulative financial savings across the three case studies amounted to $608,547, with energy savings of 40,987.65 GJ and an emissions reduction of 2,809.65 tons of CO 2 . Despite focusing on different industries, the findings are applicable to a broad range of sectors, as the core components of steam systems are widely shared. Additionally, this work supports the African Union's Agenda 2063 and the United Nations sustainable Development Goals (sDGs) by providing practical insights and recommendations for improving industrial energy efficiency and reducing environmental impact.

The demand for natural fiber-reinforced composites in engineering design has increased, offering advantages like low density and environmental benefits. However, their long-term behavior, particularly under cyclic loading, remains limited. This study aims to predict the fatigue behavior of composites reinforced with natural fiber using several predictive models of regression trained on a database of studies. This model reduces experimental testing and improves prediction quality by avoiding computationally intensive data points.

The moroccan industrial sector has considerable share in the total energy consumption of the country (22%). Furthermore, it is mainly based on fossil energy sources and thus responsible for 13% of national energy related CO 2 emissions. However, to bring this sector on the path of decarbonization, industrial energy efficiency is a key axis for this energy transition. The purpose of this article is to draw up the findings of scientific research in the field of energy efficiency in the moroccan industry. To do this, 15 relevant articles have been systematically selected and analyzed to develop a four-dimensional classification scheme: energy audit, energy prediction, energy optimization and, energy efficiency drivers and barriers. Once this is accomplished, the gaps in this topic have been highlighted to open the way for future research issues. The main pointed out gaps are related to the lack of benchmarking tools, key performance indicators, energy efficient production planning and, machine learning models.

in The introduction of biomaterials into the realm of 3D printing represents a significant advancement with manifold implications in the fields of medicine, biomedical research, and customized manufacturing. 3D printing, also known as additive manufacturing, provides an innovative method for creating three-dimensional objects with precision and complexity, layer by layer. in this study, we conducted a numerical simulation of a biomaterial composed of a bioload in the form of chicken feathers randomly distributed in a matrix of PLA (polylactic acid), a material widely used in 3D printing. in this article, we numerically investigated 3D printing technology to create a biomaterial before advancing to a bio-printing stage. The results indicate an increase in stiffness accompanied by a reduction in density with an increase in the percentage of bioload, resulting in a decrease in density of approximately 0.1 g/cm3 and an increase in Young's modulus of 0.5 GPa. Aligned with the industrial trend focused on decreasing weight relative to volume, along with the potential utilization of chicken feather and PLA waste during recycling, explored in forthcoming articles.

High-density polyethylene (HDPE) is increasingly used in the manufacture of culverts and drainage pipes because of its many advantages. The question of the longevity of HDPE pipes made from recycled resins compared with those made from virgin resins has aroused growing interest in the scientific community. several recent studies have confirmed the high durability of HDPE, estimating its lifespan at over 100 years. However, external factors, such as environmental conditions and operating constraints, can influence this longevity. However, its oxidative thermal ageing is crucial to its durability. This study investigates the effects of thermo-oxidative ageing on the mechanical and physico- chemical properties of PE, highlighting the degradation mechanisms induced by prolonged exposure to high temperatures and oxygen. A method combining experimental tests and predictive modelling was developed to assess the lifetime of the materials. The Arrhenius model was used to estimate degradation kinetics and predict PE lifetime as a function of ageing conditions.
