Halophyte-derived biochar for organic removal from biogas slurry: Tunable adsorption performance and mechanism by feedstock type and pyrolysis temperature

Key Points

• Organic removal efficiency from biogas slurry is notably influenced by feedstock type and pyrolysis temperature.
• The study highlights a significant adsorption performance variability, ranging from 75% to 90% based on specific conditions.
• Investigation employed a mechanistic approach to understand the adsorption properties of biochar derived from halophytes.
• Findings suggest potential for tailored biochar to enhance waste management processes in various agricultural settings.
