NOVELTY - Making a burnable fuel comprises: providing a source material to form an input material, where the source material comprises at least one waste or used material including a complex mixture of components, where the components comprise e.g. used or waste industrial materials, healthcare materials, medical materials, and/or metal materials; and sizing or sizing and partially or completely homogenizing the input material into a particulate burnable fuel, where the fuel is suitable for use as a fuel for e.g. cement plants, power plants and municipal incinerators for steam generation.    USE - The method and system are useful for making a burnable fuel from used or waste materials (including industrial materials, municipal materials, healthcare materials, medical materials, agricultural materials, biomass materials, electronic materials, and/or metal materials) for use as a fuel for cement plants, power plants, municipal incinerators for steam generation, and any other facility that burns fuels and converts heat derived from the burning of the fuel into a usable form of energy or for use of the heat and/or ash to make an end product (all claimed).    ADVANTAGE - The method provides conversion of used or waste materials directly into a burnable fuel without the need for exhaustive component separation.    DETAILED DESCRIPTION - Making a burnable fuel comprises: providing a source material to form an input material, where the source material comprises at least one waste or used material including a complex mixture of components, where the components comprise used or waste industrial materials, municipal materials, healthcare materials, medical materials, agricultural materials, biomass materials, electronic materials, and/or metal materials; and sizing or sizing and partially or completely homogenizing the input material into a particulate burnable fuel, where the fuel is suitable for use as a fuel for cement plants, power plants, municipal incinerators for steam generation, or any other facility that burns fuels and converts heat derived from the burning of the fuel into a usable form of energy or for use of the heat and/or ash to make an end product. INDEPENDENT CLAIMS are also included for:    (1) a system for making a burnable fuel comprising: a material supply subsystem, where at least one source material is collected to form an input material for subsequent system processing, where the input material includes many components, and a sizing or sizing and homogenizing subsystem, where the input material is sized or sized and partially or completely homogenized to produce a particulate burnable fuel having a desired particle size distribution for use as a fuel or fuel component suitable for use in cement plants, power plants, municipal incinerators for steam generation, or any other facility that burns fuels and converts heat derived from the burning of the fuel into a usable form of energy or for use of the heat and/or ash to make an end product; and    (2) a burnable fuel composition comprising a burnable fuel including a sized or sized and partially or completely homogenized input material, where the input material comprises at least one waste or used material, where each material comprises a complex mixture of components, where the materials are used or waste industrial materials, used or waste municipal materials, used or waste healthcare materials, used or waste medical materials, used or waste agricultural materials, used or waste biomass materials, used or waste electronic materials, and/or used or waste metal materials, where the fuel is suitable for use in cement plants, power plants, municipal incinerators for steam generation, or any other facility that burns fuels and converts heat derived from the burning of the fuel into a usable form of energy or for use of the heat and/or ash to make an end product.
