Cattle hair biochar has good adsorbent properties which can be enhanced by alum but has not been tested before. Testing of used biochar/alum adsorbent as fertilizer is scarce despite the organic fertilizer role of biochar which can be enhanced by organics and inorganics like phosphate adsorbed from the effluent. This study is aimed at evaluating the efficiency of cattle hair waste biochar fortified with alum in removing colour and sulfate from vegetable oil refinery wastewater and investigating the effects of used adsorbents on the growth performance of maize. Biochar produced by pyrolysis at 465 °C gave a yield of 69.36 % and was characterized using FTIR, XRD, and SEM-EDX analysis. Colour and sulfate removal were studied using the parameters such as contact time without stirring, stirring time, concentration, pH dose of biochar and temperature were studied. Biochar/alum recovered after water treatment was tested as fertilizer on growth performance of maize for 34 days. This biochar is rich in carbon, very porous and contain C-O and OH^- groups. The percentage removal of colour removed was higher than that of sulfate for all the parameters. For example, colour removal attained a maximum of about 98 % in 40 mins without stirring, against 74 % in 10 mins for sulfate. When the process is stirred, equilibrium is attained in 20 mins for both colour and sulfate with respective removal efficiencies of 95 and 77 %. 100 % colour was removed at pH 4–10 against pH 6 for maximum sulfate removal. Maximum colour removal of 97 % occurred at 25 °C and 86 % for sulfate at 20 °C. Colour removal is more favourabele K_L = 478.468 ABS g⁻¹ compared to 0.619 L g⁻¹ for sulfate. Recycled adsorbent after treatment showed better maize growth performance than the control (the average leaf area index was 282.2 ± 36.7 on day 34 for recycled adsorbent treatment compared to 210.5 ± 13.5 for the control). Tested biochar fortified with alum is very efficient in improving the quality of studied wastewater, and the recycled adsorbents enhance maize growth.</div></div>","PeriodicalId":101197,"journal":{"name":"Sustainable Chemistry One World","volume":"6 ","pages":"Article 100061"},"PeriodicalIF":0.0,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143881838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its leaves naturally accumulate steviol glycoside (SVglys) sweeteners. Currently, the demand for calorie-free sweeteners has prompted researchers to study other \"natural\" sweeteners that can replace sugar in the global market. Optimization of stevia perennial cultivation in Morocco is based upon breeding adapted high-value genotypes. The basis of a pre-breeding program is to evaluate in field conditions the performances of a large set of genotypes that could be used as genitors for new varieties. This study investigates the dry leaves production and the variability in total SVglys, rebaudioside A (RebA) and stevioside (STV) contents in stevia genotypes cultivated in two distinct regions of Morocco, Agadir and Marrakech, over four years. The analysis reveal significant year-to-year variability in dry leaf yields and SVglys content, with notable increases observed in the second year, indicating that specific climatic conditions were highly favorable during Y2. In addition, the results showed significant difference of SVglys, STV and RebA yields across the 4-harvest years. The STV represented the major SVglys in the both studied regions over the four harvest years with an amount reaching up to 12.63 %, followed by the RebA. In Agadir, the mean cumulative production per plant over four years was 518.57 g of dry leaves, 18.79 g of RebA, 51.37 g of STV and 80.87 g of SVglys. While in Marrakech, the cumulative dry leaves production was 529.9 g, 22.93 g of RebA, 41.99 g of STV and 77.95 g of SVglys.

SC-CO₂ extraction achieved a higher oil recovery (44.580 ± 0.572 %) than hexane extraction (41.783 ± 0.377 %). Notable differences in oil properties were observed. SC-CO₂-extracted oil had a higher specific gravity (0.949 ± 0.001) than hexane-extracted oil (0.913 ± 0.003), indicating improved functional characteristics. It also demonstrated superior thermal stability, with a higher flash point (320.224 ± 2.128 °C) and fire point (342.325 ± 2.248 °C) compared to hexane-extracted oil (flash point: 317.477 ± 0.467 °C; fire point: 340.786 ± 3.742 °C), making it suitable for food and industrial applications.
