Herbaceous
Herbaceous refers to plants that have non-woody stems and typically die back to the ground at the end of the growing season. These plants, which include grasses, legumes, and flowering plants, are characterized by soft, green, and flexible stems.
In the context of bioenergy and biomass, herbaceous materials, such as switchgrass, miscanthus, and crop residues (e.g., straw and corn stover), are used as feedstock for producing biofuels, pellets, and biogas. Herbaceous biomass is valued for its high growth rate and availability, making it a sustainable resource for renewable energy production.
