Converting biomass waste into valuable biomaterials and bioactive compounds: an overview of antimicrobial activities in the pursuit of global sustainability and health.

The escalating global population poses formidable challenges to addressing pressing environmental concerns, hindering progress towards sustainable development goals. Unregulated human activities, particularly the excessive reliance on fossil fuels and unsustainable agricultural practices, contribute to pollution, climate change, and resource depletion. Inadequate waste management systems exacerbate environmental degradation and pose risks to public health. Leveraging biological resources and urban/industrial waste emerges as a promising solution. Various waste materials, such as food waste and agro-industrial by-products, have been efficiently repurposed into valuable bio-based products. This review explores the diverse applications of agricultural and food waste repurposing, including microbial production of biopolymers and biosurfactants, as well as the extraction of biologically active compounds for potential antimicrobial drugs.
