The present disclosure relates, according to some embodiments, to an absorptive solid (e.g., an animal bedding) produced from a microcrop such as Lemna. An absorptive solid of the present disclosure may comprise (i) an odor-absorbing amount of chlorophyll, and (ii) a carbohydrate extracted from a microcrop, the carbohydrate itself comprising at least some of the odor-absorbing amount of chlorophyll. A process for generating an absorptive solid may comprise the actions of: (i) lysing a microcrop consisting of at least one photosynthetic aquatic species to generate a lysed microcrop； (ii) separating the lysed microcrop into a solid fraction and a juice fraction； (iii) separating the solid fraction to form a solid； and at least one of: (a) milling the solid to generate an absorptive powder, (b) shaping the solid to generate the absorptive pellet or an absorptive granule； and (c) extruding the solid to generate an absorptive extrudate.
