The microbial response to biodegradable polylactic acid microplastics during anaerobic fermentation of waste activated sludge

Key Points

• Microbial response increased with exposure to biodegradable polylactic acid microplastics during fermentation.
• Key evidence shows an enhancement in microbial activity linked to the presence of these microplastics, influencing degradation rates.
• Experimentation involved anaerobic fermentation processes on waste activated sludge with varying microplastic concentrations.
• This highlights the potential for biodegradable options to interact beneficially in waste treatment settings, requiring further studies.
