Summary: The study investigated the use of YMeat and bone meal (MBM) ash for phosphate wastewater treatment and phosphorus recovery, finding that the phosphate in the ash was mainly hydroxyapatite. Particle size significantly affected the phosphate removal capacity, with smaller sizes showing higher removal capabilities, and an acidic environment was favorable for phosphorus recovery.

Summary: The impact of wood ash on metal uptake and transfer factor of lettuce grown on soil amended with poultry litter, digestate, and its fraction was evaluated. The results showed that wood ash had positive effects on the properties of the amended soil and led to better lettuce productivity, particularly when used with poultry litter. The organic treatments had lower potential toxicity in lettuce compared to inorganic fertilizer. Therefore, wood ash can be used as a nutrient booster for organic fertilizers and an alternative to inorganic fertilizers for leafy vegetables.

Summary: This study obtained a high-quality phosphorus raw material by mixing meat-bone meal and sewage sludge, with a high P(2)O(5) content. The resulting material does not contain harmful fluoride compounds or radioactive substances, and the production process incorporates cleaner technologies and circular economy principles.

Summary: This research examines the properties of hydroxyapatite ashes obtained from burning meat and bone meal in an industrial rotary kiln. The ash has a high carbon content (10%), relatively low phosphorus (34%), and sulfides. However, by decreasing the calcining temperature and recycling the ashes with dosed meat and bone meal, it is possible to eliminate hydrogen sulfide emissions, reduce carbon content, and increase the P2O5 content in the ash. This allows the production of hydroxyapatite ash that can be used as a substitute for phosphorites in fertilizer production.

Summary: This study investigated the solubility and speciation of plant nutritional elements (K, Ca, and Si) in wood ash treated with sulfuric acid or phosphoric acid. The addition of these acids did not affect the solubility of K, but decreased the water soluble and citrate soluble K in the ash. The solubility of Ca increased significantly in the ash treated with sulfuric acid, while the solubility of Si decreased in the acid-treated ash. The degree of Si polymerization and the decrease in pH influenced the solubility of Si in the acid-treated ash. Sulfuric acid-treated ash is suitable for Ca fertilizer, while phosphoric acid-treated ash is suitable for Si fertilizer.

Summary: This study investigated the impact of biochar and coal fly ash amendments as soil amendments on the retention efficiency of soluble phosphorus fertilizer in Ultisols. The results showed that these amendments reduced the leachable phosphorus fractions in soil through various retention and fixation pathways, thereby reducing phosphorus leaching loss.

Summary: In this study, the properties of anaerobic digestate were improved by adding acids and wood ashes, achieving solid-liquid separation. The amount of water-insoluble phase of wood bottom ash increased after treatment, while the formation of water-soluble extract of wood fly ash and agrowaste digestate increased. This treatment method can be applied to the management of other organic fertilizers to reduce storage and transportation costs.

Summary: The research aimed to develop an effective, sustainable technology by using wood waste ash as an alternate binder for fly ash in concrete production. The findings showed that 30% replacement of wood waste ash yielded the best results, filling the research gap in finding an alternative binder for fly ash and demonstrating the potential environmental and economic benefits.
