The prepared composite is used to enhance the electrochemical microenvironment (ECM), hence improving the efficiency of the transesterification process to convert PCFO into methyl ester fatty acids (MEFA).

This spatial combination increases charge carrier mobility as well as electron and ion transport, thereby enhancing the nucleophilic attack of methoxide ion on triglyceride molecules. The supporting electrolyte, i.e., sodium chloride, reduces the resistance of the solution, thereby increasing charge transfer efficiency within the ECM. Under optimized conditions (25 °C, 20 V, and reaction time of 100 min), the system reaches an exceptional MEFA yield of 98.4 %.

Bone char samples were produced under different temperatures (400–1000 °C), acidified, and characterized structurally using X-ray diffraction, attenuated total reflectance Fourier transform infrared spectroscopy, and scanning electron microscopy coupled with energy dispersive spectroscopy. Bone char samples were compared with commercial P sources of high (simple superphosphate) and low solubility (Bayóvar), and with untreated bone char. Bone char produced at 400 °C was selected for a solubility assessment, including P release, soil diffusion, and soil incubation, complemented by a greenhouse experiment with maize. This material was chosen based on total P content analysis of materials across a temperature range of 400 °C–1000 °C, which revealed no significant differences, and because the low-temperature treatment exhibited the lowest energy demand. Characterization of acidified bone char (bone char-H<sub>2</sub>SO<sub>4</sub>) revealed an intense CaSO<sub>4</sub> signal. The presence of distinct phosphate and sulfate ion bands, high P solubility in water, and the elemental composition of C, O, P, S, and Ca were observer in the bone char-H<sub>2</sub>SO<sub>4</sub>. Bone char-H<sub>2</sub>SO<sub>4</sub> exhibited enhanced P solubility and high agronomic efficiency, performing comparably to simple superphosphate. The results validate the potential of bone char-H<sub>2</sub>SO<sub>4</sub> as a sustainable P fertilizer from biowastes of the meat and dairy industry.</div></div>","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"204 ","pages":"Article 108459"},"PeriodicalIF":5.8,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145325159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
