Unlocking poly(lactic acid) degradation through biochar-induced environmental shifts and functional consortia enrichment in composting systems

Key Points

• Enhanced degradation of poly(lactic acid) occurs with biochar-induced environmental changes, fostering microbial diversity.
• Microbial consortia enriched in composting systems lead to improved breakdown of poly(lactic acid), revealing vital interactions.
• Observational analysis across various composting setups identifies optimal conditions for poly(lactic acid) degradation via biochar.
• These findings imply that strategic use of biochar can promote poly(lactic acid) breakdown, benefiting composting practices.
