Oyster mushrooms grow faster and degrade plastics better when cardboard or other organic waste is mixed in.
Mixed substrates combining cellulose-rich materials like cardboard with plastics provide additional carbon sources that stimulate fungal growth. Oyster mushrooms colonize these composite substrates more rapidly, leveraging the nutrients from cellulose to produce enzymes capable of attacking polymer chains. Researchers observed higher laccase and peroxidase activity in mixed-substrate experiments compared to plastics alone. The cellulose matrix also increases substrate porosity, improving oxygen diffusion and hyphal penetration. Oyster mushrooms exhibit adaptive metabolic flexibility, allocating energy from rich substrates to challenging plastics. These findings highlight the potential to convert waste mixtures into valuable biomass while reducing synthetic polymer pollution. Applied mycology benefits from integrating unconventional substrates to enhance efficiency. The approach demonstrates innovative strategies for sustainable, circular waste management using fungi.
