Compost collection bin

Abstract

A sealable bin for collecting waste biomass in a household kitchen comprising a container for receiving biomass, a sealable lid for placement over the container, venting means for circulating air within the waste biomass, and a handle. Venting means is contained in the lid. The inside surfaces of the container have a series of parallel features comprising either channels or projections in order create pathways into and out of the container for aeration of the biomass and dehumidifying of the biomass so as to deter anaerobic decomposition and odours.

1 . A composting collection bin comprising a sealable container having a volume for receiving waste biomass; and, a lid adapted to seal said container and provide for venting of said volume within the container. 
   
   
       2 . The bin of claim further comprising a handle for comfortably carrying said collection bin. 
   
   
       3 . The bin of  claim 1  wherein the container comprises four sides and a bottom having inside surfaces, said inside surfaces comprising means for aerating and dehumidifying said waste biomass. 
   
   
       4 . The bin of  claim 2  wherein said means comprises a series of parallel recesses integral to said inside surfaces, said series of parallel recesses adapted to permit air flow from outside the container to permeate the waste biomass. 
   
   
       5 . The bin of  claim 3  wherein the series of parallel recesses are further adapted to promote evaporation of moisture within the waste biomass to the said air flow so that said moisture is carried out of the container. 
   
   
       6 . The bin of  claim 2  wherein the means comprises a series of parallel projections integral to the inside surfaces, said series of parallel projections adapted to create passages for air flow around the waste biomass. 
   
   
       7 . The bin of  claim 1  wherein said lid has a surface area and said surface area is perforated with a plurality of perforations. 
   
   
       8 . The bin of  claim 7  wherein the plurality of perforations can be opened and closed by venting means. 
   
   
       9 . The bin of  claim 1  wherein the lid is removeably hinged to the sealable container. 
   
   
       10 . The bin of  claim 1  wherein the container further includes at least one tab depending from the bottom surface of the container adopted for hand grasping when the lid is in a rearward position. 
   
   
       11 . The bin of  claim 2  wherein the container includes two adjacent dished tabs depending from the bottom surface thereof and adopted for hand grasping.
