Multistage treatment of almonds waste biomass: characterization and assessment of the potential applications of raw material and products

Almond shells are waste biomass generated in agro-industrial activities, which represent a resource that can be further valorized upon treatment. The purpose of this work was to assess new value-added products obtained through a novel multi-stage delignification process of almond shells. A comprehen...
