(IN200500823-I3)   NOVELTY - Apparatus for treating biomass/organic waste, comprises: a container incorporating a shaft at the axis, affixed on which are plough type blades and an opening preferably at the top side for feeding the material; a chopper assembly (15), where at least the blades of the chopper assembly are inserted into the container; a discharge assembly preferably connected at the bottom side of the container; and a door at the connecting junction of the container and the discharge assembly, which can be opened and closed. The door may be a part of the container or the discharge assembly.    USE - The apparatus and the method are useful for converting biomass/organic waste to organic fertilizer (claimed) and fuel for domestic, and industrial heating.    ADVANTAGE - The apparatus is simple, convenient to operate, economic, maintenance free, beneficial to the environment, and requires minimum efforts to operate without the need for constant attention.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a process for converting bio-degradable waste/biomass material into organic fertilizer, comprising: feeding the material into the container and chopping it; adding a microbial culture or substance obtained; optionally adding a moisture absorbing substance; running the motor for mixing, taking out the material preferably on the ground to make a heap; and ensuring aerobic conditions till the material matures into an organic fertilizer;    (2) a process for bio-stabilization of bio-degradable waste/biomass material comprising feeding the material into the container of the apparatus and chopping it; adding a microbial culture or substance obtained there from; optionally adding a moisture absorbing substance; and running the motor for mixing; and    (3) a process for converting bio-degradable waste/biomass material into fuel comprising biostabilizing the material; optionally spreading it in a suitable mould, pressing and cutting into pieces of suitable size; and drying it.    DESCRIPTION OF DRAWING(S) - The drawing shows the chopper assembly with blades inside the container.    chopper assembly (15)
