Biogas purification and enrichment: sustainability metrics analysis of dry anaerobic digester with cashew apple bagasse substrate

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study hypothesizes that cashew apple bagasse‐based anaerobic digestion, combined with biochar purification, enhances biogas quality and sustainability. This study aims to investigate the performance and sustainability of a biochar‐based biogas purification technology using cashew apple bagasse as a substrate, with a focus on environmental
