Ammonia-Derived Acidic Compound Pretreatment: Fractionation of Lignocellulosic Biomass for Boosting Enzymatic Hydrolysis to Efficiently Produce Bioethanol by Yeast.

Development of pretreatment to reduce biomass recalcitrance is essential to produce fermentable sugars, which is used as carbon sources for microorganisms to synthesize biofuels. Lignin in lignocellulose is generally removed by alkaline pretreatment (e.g., NH4OH, ethanediamine), while the severe environment causes equi...

Ammonium Hydroxide Pretreatment of Sugarcane Bagasse and Corn Cob: Saccharification Enhancement and Ethanol Production by C6/C5 Cofermentations

The pretreatment of lignocellulosic biomass is a key step in second-generation (2G) ethanol production. In this study, sugarcane bagasse (SCB) and corn cob (CC) were pretreated with 28–30% ammonium hydroxide (1:10 w/v ratio, 30 min, 180 °C) to promote lignin removal and enhance enzymatic hydrolysis. Delignification lev...

Biomass and Activated Carbon from Zea mays Stems as Potential Adsorbents of Acid Green 25 from Aqueous Solutions—Kinetics, Isotherms, Thermodynamics, and Theoretical Study

In the present research, Zea mays stem (ZMS) agricultural waste and its corresponding activated carbon (AC-ZMS) were successfully utilized as alternative low-cost adsorbents for the removal of Acid Green 25 (AG25), a highly resilient and toxic contaminant textile dye. The evaluation was systematically conducted using s...

From Waste to Resource: Upcycling Spent Coffee Grounds into Biochar Functionalized with CaFe2O4 for Phosphate Removal

Eutrophication caused by excess phosphorus in water bodies represents a significant environmental challenge, requiring efficient, selective, and sustainable technologies for its mitigation. In this study, a magnetic biochar (BiMag) was developed through the valorization of residual coffee grounds and functionalized wit...

One-step H3PO4-activated pyrolysis of cocoa (Theobroma cacao) shell waste: insights into product characteristics and adsorption performance

The conversion of agricultural residues into high-performance adsorbents offers a sustainable approach to treating dye-contaminated wastewater. Cocoa shell (CS), a major agro-industrial byproduct of Theobroma cacao, contains approximately 21.20% cellulose, 20.12% hemicellulose, and 51.93% lignin, making it a promising...
