Valorization of Lignite Use in “Green” Technologies: A Review
The increased utilization of lignite in "green" technologies represents a critical step toward the rational use and valorization of low-grade fossil fuels. This study examines the current state of lignite deposits in Ukraine and explores its potential applications in non-energy and environmentally sustainable energy sectors. The chemical composition of humic acids derived from brown coal was analyzed, along with their ability to undergo hybrid modification with biodegradable materials such as hydrogels, biofilms, and composites.
