Claim 7:
8. A system for making a rigid foam substitute comprising:
a cleaner configured to remove trash from at least two decompressed natural fiber materials that were mixed during an opening process,
wherein said cleaner breaks said at least two decompressed natural fiber materials into pieces of natural fiber material via a plurality of rollers having a specific length,
wherein trash of said at least two decompressed natural fiber materials is removed from said at least two decompressed natural fiber materials while said at least two decompressed natural fiber materials are broken into said pieces of natural fiber materials,
wherein said trash of said at least two natural fiber materials comprises at least one of leaf, stone, iron particles, jute, polypropylene, colored fibers, and feather,
wherein said trash of said at least two decompressed natural fiber materials is removed by at least one of a comb and paddle of said cleaner,

a mixer operably connected to said cleaner and configured to create a fluidic mixture within a vat using said pieces of natural fiber material, a liquid, and a natural binding material,
wherein said pieces of natural fiber material are received in a first hopper of said mixer,
wherein said natural binding material is received in a second hopper of said mixer,
wherein said pieces of natural fiber material of said first hopper and said natural binding material of said second hopper are transferred to said vat of said mixer,
wherein said pieces of natural fiber material received from first hopper and said second hopper differ in at least one of size, grade, source, or type,
wherein a specified amount of a liquid is transferred to said vat,
wherein said mixer maintains a desired temperature range while said pieces of natural fiber material, liquid, and natural binding material are mixed within said vat,

a molder operably connected to said mixer and configured to shape said fluidic mixture into a cast having a desired shape,
wherein said molder automatically receives said fluidic mixture from said mixer and compacts said fluidic mixture into at least one mold to create a cast,
wherein said desired shape of said cast is based on said at least one mold within said molder,
wherein said cast is pushed out of said at least one mold, and

a kiln operably connected to said molder and configured to cure said casts.
