A Review of Nature-Based Solutions for Valorizing Aromatic Plants’ Lignocellulosic Waste Through Oyster Mushroom Cultivation

A creative, nature-based way to solve environmental issues and promote sustainable development could be the cultivation of Pleurotus spp. mushrooms to use the lignocellulosic waste from Medicinal and Aromatic Plants (MAPs). Pleurotus species are characterized by flexibility and biodegradative capacities to generate bioactive compounds with antibacterial, antioxidant, and nutraceutical properties using lignocellulosic substrates. Aromatic plant residues, such as those from lavender, sage, and mint, can improve the resultant mushrooms’ metabolic profiles and act as nutrient-rich substrates. Higher levels of phenols, flavonoids, and terpenoids can be among these enhancements, which could make mushrooms useful as functional foods. This strategy could provide scalable and affordable waste management solutions by utilizing already existing agricultural systems, including mushroom cultivation, during slow times. Incorporating Pleurotus-based systems can help to produce renewable bio-based products, reduce pollution, and improve soil health. This study not only attempts to demonstrate how Pleurotus species may convert industrial and agricultural waste into valuable, bioactive products, reducing waste and promoting ecological remediation in a circular economy, but also to highlight the viability of using natural processes for economic and environmental sustainability. To exploit the potential of this nature-based approach, future research should concentrate on maximizing substrate consumption, scaling these solutions to industrial levels, and guaranteeing regulatory compliance.
