Influence of anaerobic digestate and wood ash on phenanthrene bioaccessibility and mineralisation in soil

Key Points

• Phenanthrene bioaccessibility increased with anaerobic digestate, indicating improved degradation potential in contaminated soil.
• Mineralisation rates showed significant enhancement by wood ash, leading to more efficient soil recovery.
• Assessment using soil samples treated with anaerobic digestate and wood ash demonstrated effective remediation of pollutants over four months.
• Findings highlight the potential use of these additives in waste management strategies for soil health improvement.
