Current forestry practices often generate significant waste biomass in the form of bark and other non-timber components. This approach overlooks the potential value of these residual materials. This waste biomass generally ends up filling landfills. In this study, we explore the multifaceted utilization of Red Sanders (Pterocarpus santalinus L.) bark, a valuable endemic tree species. Red Sanders bark, typically discarded, possesses a unique composition rich in bioactive compounds with potential applications. The extracts exhibit UV radiation protection and antifungal properties, suggesting its suitability for developing coating and antifungal agents. Furthermore, the high lignin content makes it a promising candidate for lignin valorization, transforming lignin into bio-adhesives. Additionally, the bark’s high calorific value allows for conversion into bio-briquettes, a sustainable fuel source. The residual cellulosic material can be further utilized in paper production or vermicomposting. This comprehensive approach transcends the traditional focus on timber, transforming waste into valuable products for a more holistic and responsible approach to forest resource management.
