Definitions

• This invention relates to a composter. More particularly, but not exclusively, this invention relates to a toiiet
• Waterless toilets are well known. Generally, they are relatively expensive and include moving parts such as fans and rotating drums.
• a composter includes a liquid lank through which liquid can be circulated, the liquid tank being coupled to or containing a liquid heater, a perforated housing located above the liquid tank and into which perforated housing material to be composted can be discharged, a removable container interposed between the perforated housing and the liquid tank in which receptacle composted material from the perforated housing can be discharged, a cover located over the perforated housing, and a closure in the cover through which closure access can be gained to the perforated housing, so that Jn use of the composter, air heated by liquid In the liquid tank can pass upwardly through the composter and draw fresh air into the composter to facilitate composting of material In the perforated housing.
• the liquid heater is a solar heater, with a closed liquid circuit being formed between the solar heater and the liquid tank.
• Circulating means is preferably provided between the sofar heater and the liquid tank.
• the ctrcutating means may be a pump.
• the pump may be powered by an electricaf solar panel.
• the liquid tank may have a capacity of about 10 fitres and the total liquid capacity of the sofar heater and the liquid tank may be in the order of 30 litres.
• the sofar heater may be about 1 m 2 fn size. Suitable anfi-freeze may be added to the water to reduce the freeztng temperature of the water to prevent the water from freezing and damaging the liquid tank, the solar heater and associated piping.
• Insulating means may be provided below the liquid tank.
• the insulating means is a layer of ciosed-cell rubber foam.
• the composter is preferably supported on a base which may itself be made of an insulating material.
• the base Ss made of solid rubber.
• the perforated housing is preferably supported on legs and has perforated sidewails, an open top, and a grid located over an open bottom.
• the grid may be formed by a plurality of spaced elongate members located at their opposite ends in apertures in opposed sldewalts of the perforated housing.
• the elongate members may be pipes. Preferably they are 25 mm pipes.
• a rake may be provided for raking material in the perforated housing.
• tines of the rake locate between the elongate members of the grid, and the handle of the rake projects through the perforated housing and the cover, so that the rake can be manipulated from the outside of the cover to d ⁇ sfodge materiaf caught between the elongate members of the grid.
• the rake may also include blades extending upwardly from its head for aerating the manure and shredding paper.
• the composter is a waterless toilet.
• the waterless toilet preferably includes a chimney connected to the cover to facilitate a draft through the c ⁇ mposter.
• the waterless toilet preferably has a toilet seat supported on the cover, and a closure in the form of a toM seat cover.
• the removable container may be in the form of a drawer.
• the drawer is preferably narrower than the perforated housing so that in use fiquid in the form Df urine can be discharged through apertures in the sidewalls of the perforated housing onto the liquid tank without entering the drawer.
• the drawer preferably contains some perforations through which any liquid entering the drawer can be discharged.
• the liquid tank may have circumferentially upwardly extending sidewalls to form a tray within which urine can collect to be heated by hot liquid in the liquid tank and then evaporated from the tray.
• the liquid circulated through the liquid tank is preferably water-
• Kit for a composter Includes liquid tank, perforated housing, removable container, and cover as described above.
• the comp ⁇ ster may be a waterless toilet, In which event, the ioilet preferably Includes a chimney, solar panel and a pump as described above.
• a method composting material includes the steps of heating liquid in a solar panel, circulating the heated fiquid through a liquid tank located below a perforated housing containing material to be composted thereby causing an inflow of fresh air which is heated and in turn heats ihe material to facilitating the composting of the material.

• a composter in the form of a waterless toilet 10 includes an outer cover 12 with an opening 14, a toiiet seat 16, a toilet seat cover 18 and a chimney 20.
• the outer cover 12 has an opening 22, which contains a drawer 24 siidabiy located in drawer slides and removable from the outer cover 12.
• a solid rubber baseplate 26 is located below the outer cover 12.
• the base of the outer cover 12 is located within sidewaiis 28 of a tray 30.
• the base of the tray 30 Is formed by the upper surface 32 of a liquid tank, here a flat hot water tank indicated with the reference numeral 34.
• a perforated housing or basket 36 has legs 38, four perforated sidewaiis 40, an open top 42, an open base 44, ancl a grid 46 formed by spaced pipes 48 located above the open base 44.
• the perforated housing 36 stands in the fray 30 on the hot water tank 34.
• rake 50 is provided for raking the manure in the perforated housing 36.
• the rake has a head 52 with tines 54 and sharpened blades 56 extending in the opposite direction to the fines 54.
• a handle 58 extends from the head 52.
• a removable knob 60 is located at the end of the handle 58.
• the fines 54 locate between the pipes 48 of the grid 46, and the handle 58 of the rake 50 extends from the outer cover 12.
• the hot water tank 34 is connected to a solar heater 70 via piping 72.
• the solar heater 70 includes an electrical solar panel 72 and a pump 74.
• the electrical s ⁇ lar panel 72 provides electrical power for the pump 74.
• the hot water tank 34 has a capacity of about 10 litres and the total liquid capacity of the solar heater 70 and the hot water tank is in the order of 30 litres.
• the solar heater 70 is about 1 m 2 in size. It is envisaged that a suitable arrti-freeze can be added to the water to reduce Vne freezing temperature of trie water to prevent the water from freezing and damaging the hot water tank, the solar heater 70 and associated piping.
• insulating means can be provided below the hot water tank.
• the insulating means is a layer of closed-cell rubber foam.
• the solar heater 70 heats water therein, and the hot water is circulated by the pump 74 through the hot water tank 34. Fresh air is drawn into the outer cover 12 as the air Is heated by the hot water. The rising heated air heats manure in the perforated housing 36.
• the chimney 20 assists in providing a draft and a constant influx of fresh air Into the toilet.
• the rake 50 is periodically moved to and fro to clear any blockages on the grid 46, to shred paper and to aerate the manure in the perforated housing 36. Composted material falls through the grid 46 into the drawer 24.
• the drawer 24 is removed from the toilet to discard the composted materia!. Any urine ⁇ the fray 30 is heated and evaporates.
• the drawer 24 is spaced from the tray 30, and hence any urine in the tray 30, fay drawer slides. This allows the urine to evaporate without hindrance from the drawer 24.
