Summary: This study investigated the removal of cadmium (Cd) and nickel (Ni) by Pseudomonas stutzeri immobilized on rice husk biochar (PRHB). The results showed that PRHB exhibited a higher removal efficiency compared to free cells, which could be attributed to multiple mechanisms such as adsorption, ion exchange, complexation, precipitation, and bioaccumulation caused by the biochar carrier and bacteria.

Summary: A hydrothermal pre-treatment method was developed to improve sewage sludge quality and biocrude yield by solubilizing nitrogen-containing compounds. The pre-treatment successfully transferred nitrogen into the aqueous phase and retained carbon in the solid phase, leading to increased biocrude yield and quality.

Summary: In this paper, a method for the determination of antibiotics and their metabolites in sewage sludge and agricultural soil was proposed. The method utilizes ultrasound-assisted extraction, dispersive solid-phase extraction clean-up, and liquid chromatography-tandem mass spectrometry. The method was validated and showed good accuracy and precision. The results revealed that macrolides and fluoroquinolones were the antibiotic classes found at the highest concentrations in all types of samples.

Summary: This study aims to develop an efficient process for extracting saponifiable lipids and preparing biodiesel from sewage sludge. Results showed that direct extraction method using hexane at room temperature was able to achieve saponifiable lipids' extraction in the range of 19-21.5 wt%. These extracted lipids were then converted into biodiesel through acid/base transesterification with high yields and conversion efficiency. Biodiesel produced from sewage sludge has potential as a carbon-neutral fuel with low cost and low sulfur content.

Summary: In this study, a series of nickel-based bimetallic catalysts supported on homemade SiO2 nanospheres were investigated for the decarboxylation of fatty acids. The NiCo/SiO2 catalyst showed the best performance, achieving high conversion and selectivity. The synergy between Ni and Co and the carbon resistance properties of homemade SiO2 contributed to the efficient decarboxylation reaction. The NiCo/SiO2 catalyst was also successfully applied for the upgrading of MS HTL bio-crude, resulting in a significant improvement in the theoretical higher heating value (HHV), indicating the potential for converting MS bio-crude to biofuels.

Summary: This paper focuses on upgrading sewage sludge-derived pyrolysis oil through hydrotreatment using catalysts. The results show that effective heteroatom removal can be achieved, especially with the NiMoPS/Al2O3 catalyst at 400 degrees C. Additionally, the catalysts used in the process accumulate certain impurities, indicating the importance of selecting appropriate catalysts and construction materials for further study.

Summary: The global environmental problems caused by sewage sludge generated from population growth and urbanization have caught the attention of scientists worldwide. This study explores the potential of using sewage sludge from wastewater treatment plants to improve and stabilize collapsible soils. Different soil-sludge mixtures with varying percentages of sludge were analyzed through physical, chemical, and edometric experiments. The findings suggest that adding sludge to the soil reduces void index, enhances particle packaging, and decreases soil collapsibility at specific dry apparent weights, making it a promising method for improving collapsible soils.

Summary: The study evaluated the efficacy of various P-La modified sewage sludge biochars on soil phosphate-retention and ryegrass growth in alkaline soil. Results showed that La-SSBC-P treatment significantly improved plant growth and altered soil characteristics. La-SSBC-P biochar could potentially serve as a substitute for P-fertilizer, with further field experiments needed for validation.

Summary: The study evaluated the selective phosphorus recovery from sewage sludge ashes using wet chemical extraction and precipitation, achieving efficiency between 54% and 92%. Optimal operating conditions included sulfuric acid at 0.2M, liquid-to-solid ratio of 20, and contact time of 2 hours. However, some elements exceeded limits for fertilizer application, necessitating further purification steps.

Summary: Mechanical sludge dewatering is an essential step in municipal wastewater treatment to reduce sludge generation and transportation cost. This article discusses the theory of flocculation, sewage sludge, and its dewatering process. It explores the mechanisms, kinetics, and classification of flocculants, as well as the impact of various parameters on the efficiency of flocculation and dewatering. Experimental studies on different types of sludge are compared, and the literature review provides insights into the progress and future directions in this field.

Summary: The study aimed to determine the effect of Tytanit foliar application on Festulolium braunii fiber fractions, nutritional value, and feed intake, comparing it with nitrogen. Results showed that reducing traditional nitrogen fertilizers and using Tytanit instead can improve forage quality. Higher Tytanit doses led to increased NDF and ADF content, but decreased RFV, ADL, and DMI for Festulolium braunii.

Summary: The aim of the research was to evaluate the impact of slurry and soil conditioners on the yield and selected parameters of Phleum pratense, as well as on soil nutrients. The study also aimed to determine whether the combined application of slurry and soil conditioners would lead to increased accumulation of nitrogen, phosphorus, and potassium in the soil compared to the application of slurry alone or with NPK fertilizers. The results showed that the interaction of slurry with Humus Active or Rosahumus significantly increased the biomass of Phleum pratense, and the interaction with Rosahumus also increased its crude fiber content.

Summary: The aim of this experiment was to evaluate the impact of different organic materials on the yield of Dactylis glomerata, the content of selected macroelements (K, Ca, and Mg), and the ratios of K:Ca, K:Mg, and K:(Ca + Mg). Dactylis glomerata is a common forage plant in Poland due to its rapid growth, resistance to various conditions, and adaptability to meadows, pastures, and grasslands. A three-year pot experiment was conducted in a greenhouse, involving the application of organic materials (chicken manure, mushroom substrate, and rye straw) mixed with soil before the experiment. The results showed that the use of mineral and organic fertilizers significantly increased the yield of Dactylis glomerata, with the highest biomass yield observed in the groups treated with manure, straw, and mineral fertilizers, as well as mushroom substrate, rye straw, and mineral fertilizers.
