Abstract Post‐harvest agricultural residues in Latin America are commonly underutilized, leading to greenhouse gas emissions and lost opportunities for bio‐based value creation. This study tests the hypothesis that decentralized, farmer‐scale pyrolysis technologies can deliver comparable agronomic benefits while exhibiting distinct techno‐economic and ...

Abstract The long‐term viability of Jatropha curcas as a biodiesel feedstock has been widely debated. Many early initiatives failed to deliver consistent economic returns despite promising environmental attributes. This study re‐evaluated J. curcas‐based systems within an integrated environmental–economic framework, focusing on their potential role in ...

Abstract The development of renewable energy sources is important in order to achieve the United Nations Sustainable Development Goals (SDGs). Waste cooking oil (WCO) is a promising feedstock for biodiesel production through transesterification. Heterogeneous bifunctional catalysts offer a sustainable alternative to conventional homogeneous bases such ...

Potassium hydroxide activation of microalgal biochar for improved adsorption efficiency
Abstract Activated carbon was prepared from Chlorella by carbonization and potassium hydroxide activation, and its structural properties and methylene blue (MB) adsorption performance were evaluated. Raw Chlorella exhibited an adsorption capacity of 287.2 mg g−1, which decreased to 214.8 mg g−1 after carbonization.
