Comparative field‐scale assessment of TLUD and Kon‐Tiki biochar systems: agronomic performance and net CO2e‐based techno‐economics

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
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 ...

Integrating agro‐residue valorization and clean hydrogen production: coconut fiber‐based catalysts for NaBH4 hydrolysis

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract A novel phosphoric acid‐treated green coconut fiber (GCF‐C) was developed as a catalyst for hydrogen production from the hydrolysis of sodium borohydride (NaBH4). Characterization techniques confirmed structural modifications, including X‐ray diffraction, scanning electron microscopy, X‐ray fluorescence, Fourier transform infrared, and ...
