Summary: The ash generated from biomass combustion in electricity generation plants is a waste that has increased significantly in recent years, posing an environmental problem. Various studies have shown the technical feasibility of recovering biomass ash as a replacement for natural materials in civil engineering applications and construction material manufacturing. This study evaluated the use of biomass ash in the production of lightweight concrete, replacing sand (15%-25%) and expanded clay (25%-35%), as well as replacing cement after grinding the ash. The results showed improved mechanical performance and reduced thermal conductivity of lightweight concrete, making it suitable as an insulating material in construction.

Summary: This study investigated the effect of using olive pomace bottom ash as an additive in the manufacture of fired clay bricks. Adding 5% of olive pomace ash significantly increased compressive strength, but adding 20% increased porosity. Although excessive additions did not affect thermal conductivity, they led to increased water absorption, which is not desired in construction materials.

Summary: By pyrolyzing, physically activating, and sulfonating olive pomace, the activated carbon's surface area significantly increased, its structure changed to become microporous, and tar residues and aliphatic hydrocarbons were removed. Comparing to coconut husk-based activated carbon, the olive pomace activated carbon fixed three times less sulfur. After esterification reaction, the acidity of olive pomace oil and glycerides were effectively reduced.

Summary: In this study, the drying of olive pomace using a hot-air-assisted radio frequency system (HA-RF) was investigated. The effects of radiofrequency electrode distance, sample thickness, and compaction density on drying rate were evaluated. The results showed that the best drying conditions were achieved with a 10 cm product thickness, a 0.45 g/cm(3) compaction density, and a 105 mm electrode distance. The HA-RF system reduced the drying time compared to hot air drying and radiofrequency drying, and had no significant impact on the quality of the extracted olive pomace oil.

The (La0.2Gd0.2Y0.2Yb0.2Er0.2)2(Zr1-xCex)2O7 (x = 0-0.5) high-entropy ceramics with a single defective fluorite structure were successfully prepared. The thermal conductivities of these ceramics showed an unusual behavior, which can be attributed to the increased electronic and photon thermal conductivities and reduced phonon-grain boundary scattering.

Summary: Designing healthier lipids is an approach to developing potential functional foods. This study focused on olive pomace oil (OPO) and developed puff pastry margarines (PP-M) with high OPO content. The physical-chemical, mechanical properties, lipid profiles, and sensory analysis were evaluated and compared to commercial puff pastry (PP) butter and fatty preparation (CFP). A new margarine with high OPO content was formulated, which resulted in puff pastry with adequate performance, sensory quality, and a healthy lipid profile.

Summary: The efficiency of Rhodotorula mucilaginosa 1S1 as an Ag(I) biosorbent and its ability to biosynthesize recoverable silver nanoparticles have been evaluated. The process follows pseudo second-order kinetics and the Freundlich model, while optimal operational conditions are determined at 27 degrees C. Thermodynamic analysis shows positive values for enthalpy and entropy, indicating a spontaneous process, and a negative value for Gibbs free energy. The biomass exhibits a maximum biosorption capacity at 19 degrees C, and is capable of synthesizing silver nanoparticles with sizes between 12 nm and 20 nm.

Summary: This work investigated three process configurations for the biorefinery of olive oil mill leaves (OL), which include natural antioxidants, lignin, and bioethanol. Configuration 1 achieved the simplest process but had poor biomass fractionation. Configuration 2 included ethanol extraction to enhance the recovery of natural antioxidants. Configuration 3 achieved better fractionation and the highest bioethanol production with a yield of 71% of the theoretical yield. It also generated a liquid stream with higher lignin content, facilitating the obtainment of high purity lignin.

Summary: This study investigates the use of vine shoots as a renewable and widely available feedstock for hydrogen production. The results showed that physical, chemical, and biological pre-treatments can enhance the hydrolysis and fermentation of vine shoots into hydrogen. Laccase pre-treatment was found to be the most effective, leading to increased production of soluble sugars and hydrogen. Additionally, the addition of cellulase during hydrolysis further improved hydrogen production. These findings have practical implications in the field of biomass energy.

Summary: The traditional biodiesel production model using edible oils as raw materials is unsustainable due to high costs, competition with the food sector, and environmental threats. Shifting to non-edible oils as raw materials for biodiesel production offers the opportunity for increased sustainability and avoiding conflicts with food production. Processing non-edible oilseeds generates large amounts of residues, which can be upgraded to advanced biofuels and high-value products through bioconversion. However, pretreatment is required to enhance the susceptibility of these residues to enzymes and microorganisms.

Summary: This study analyzes the erosion mechanisms of NaCl solution on asphalt concrete and finds that NaCl solution softens asphalt and promotes the intrusion of crystalline salt into it. Salt crystallization alters the surface roughness of aggregates, resulting in a decrease in skid resistance but an improvement in compressive strength. Additionally, the concentration of NaCl solution initially has no significant impact on the mechanical performance of asphalt concrete, but its domination gradually increases with the intensification of cyclic effects.

Summary: This paper investigates the effect of freezing and thawing cycles on the tensile behavior of cracked ultra-high performance concrete (UHPC). The results show that long-term freezing and thawing action deteriorates the cracking strength, tensile strength, tensile strain, and strain energy of cracked UHPC. On the other hand, the action of water generally favors the development of tensile properties of UHPC. The crack distribution tends to be unsaturated under freezing and thawing environment, and the re-hydration reaction is hindered. The pore structure near the crack varies under different environments.

This study focuses on solidifying tailing sand using microbial induced calcite precipitation (MICP) to improve strength and fix heavy metals. The curing time of MICP bio-cemented tailings is found to significantly impact the strength of tailings, while its effect on heavy metal fixation is minimal. The optimized MICP curing time is 10 days, resulting in improved strength and cementation of tailings particles.
