NOVELTY - A small scale worm composter has frame (5) having a height of 50-100 cm, length of 100 cm, and width of 50-100 cm. The frame is manufactured from plastic sheets, wood or iron sheets, stainless steel or plywood of 10-60 mm thick, where frame is insulated with cardboard, and on upper side a lid (6) is placed which is opened and closes hermetically with clips. The frame can be constructed from four iron bars in conjunction with above sheets. The frame is crossed by a traverse perforated pipe from iron, stainless steel, plastic or copper that extends until the opposite backside.    USE - Small scale worm composter.    ADVANTAGE - The composter achieves high yield at optimum operation condition; is energy free without gas emissions; and converts organic wastes to humus without need of a shredder machine.    DETAILED DESCRIPTION - The small scale worm composter has frame (5) having a height of 50-100, preferably 90 cm, length of 100 cm, and width of 50-100 cm. The frame is manufactured from plastic sheets, wood or iron sheets, stainless steel or plywood having thickness of 10-60 mm, where frame is insulated outside and above with cardboard or other insulating material, and on upper side a lid (6) is placed which is opened, with the help of joints, and closes hermetically with clips. The frame can be constructed from 4 iron bars in conjunction with above sheets. The frame on the front surface is crossed by a traverse perforated pipe from iron, stainless steel, plastic or copper of 30-50 mm in diameter that extends until the opposite backside. The pipe has 2 nuts that lock the front and back side (bigger dimension) in order to offer more support to these sides of the construction, where more parallel pipes running exist for bigger height of construction. The pipes are covered with anti-mosquito mesh. The frame is provided on a constant bases (1, 2, 3, 4) constructed from iron or stainless steel bars, where additional traverse joint bars (11, 12, 13, 14) are installed every 30 cm of base length for more compact construction and resistance in load, and a mesh of stainless steel or coated iron is placed 5 mm in thickness between frame and base. The mesh has square or rectangular holes of 50-60 mm, where stainless steel or iron is placed on the mesh which can move frontward and backward inside the frame limits. The arms of bar penetrate frame via 2 holes in the down part of frame, where base is welded from metal sheets (7, 8, 9, 10) below the mesh. The base space is covered externally with metal sheet or plywood sheet, and above the sheet-metal a closed space is created for the collection of finished product. The space brings 2 opposite front doors, where 2 side covers of composter can be raised and removed in order that composter can be extended with other similar composter in row. The upper cover has a hole 70 mm in diameter, and a box is placed above with mesh for ventilation and bad smells elimination, where ready compost or carbon filter is added in the box for fermentation gases (methane, nitrous oxides, carbon dioxide) to be trapped, and a fan (with electric or solar source) can be placed above box for rejecting heat, if it is necessary, due to biochemical reactions, or due to increase of outside temperature. The water pipes with automate flow system in zigzag pattern run below the cover, in case the composter needs additional humidity supplies. The composter is equipped with electronic control unit and sensors for humidity, temperature, pH and oxygen reduction sensor for better operation and monitoring. The electronic control unit comprises LCD panel, keyboard and AVR(RTM: processor), Atmel(RTM: processor) or Intel(RTM: processor) for autonomous operation with batteries and with ports RS-232, RS-484, Universal Serial Bus, for communication. The electronic control unit checks water supplies and fan's function. The composter has flat metal plastic tray under mesh of same shape with the composter for collection of the ready product. The tray has elevated lips of approximately 5 cm, where front end of tray is provided with groove to facilitate the unloading of ready product bags. The tray also collects liquid compost tea from exaggerated water. The joints of metal frame are welded (massive construction) or screwed, (except the base that is welded) for modular construction and extension.
