The present subject matter relates to apparatuses and methods for separating grass clippings from air in a recirculating bagging apparatus for a lawnmower. For instance, a recirculating bagging apparatus for a lawnmower can include a grass-collecting compartment for collecting grass clippings discharged from a lawnmower and an air discharge channel in communication with and disposed below the grass-collecting compartment. The grass-collecting compartment can have a non-breathable bottom floor for receiving and supporting collected grass clippings. The air discharge channel can be adapted for passage of air discharged from a lawnmower through the grass-collecting compartment and out of the bagging apparatus.
