TRASH TO TREASURE (Sustainable extraction of lignin from sugarcane bagasse and its addition in hydrogels for wound healing)

The project primarily focused on the extraction of lignin and its application in the medical industry, particularly its incorporation into hydrogels for enhanced wound healing. While cellulose has long been utilized for energy generation and various other applications, lignin—a plentiful component of plants—has historically been overlooked. Once considered waste, lignin is now being repurposed in innovative ways. The developed product represents a renewable, sustainable, and eco-friendly strategy for addressing climate change. These lignin-infused plasters are designed to promote wound healing by providing moisture and antioxidant properties while maintaining a durable structure that can be used for several days. However, the project faced challenges, including a shortage of necessary chemicals in the market and limited access to required instruments.

The project focusing on the extraction of lignin and its application in the medical industry, particularly in hydrogel-based wound healing plasters, creates a significant impact on multiple fronts. Traditionally, lignin, an abundant biopolymer found in plants, has been overlooked and discarded as waste, while cellulose has dominated industrial applications. This project challenges that norm by leveraging lignin’s unique properties, such as its antioxidant capabilities and moisture-retaining qualities, to develop a more sustainable and effective solution for wound care. The lignin-based hydrogel plasters created through this initiative present a renewable, eco-friendly alternative to conventional wound dressings, offering enhanced moisture retention to promote an optimal healing environment and reduce infection risks. Additionally, the antioxidant properties of lignin help neutralize harmful free radicals, further accelerating the healing process. This innovative approach aligns with global efforts to mitigate climate change by utilizing renewable resources and reducing waste. The challenges encountered, including limited access to specific chemicals and instruments, underscore the need for better resource allocation in research fields. Nevertheless, this project paves the way for future innovations in biopolymer applications, demonstrating lignin’s potential beyond its traditional, overlooked status, and emphasizes the importance of sustainable materials in advancing medical technologies and reducing environmental impact.
