    In the present invention there is provided an integrated method for classifying solid waste comprising combinations of fractionation techniques that include, but are not limited to, manual separation, separation according to the size of the material, separation according to the density of the material, separation according to the dimension of the material, separation according to the optical properties of the material, and separation according to absorption properties
    20 x-ray material. The procedure provides for the efficient generation of several high-value recovered streams for recycling and conversion into higher value products including (1) clean bio-wastes that are suitable for glucose production, (2) recycled streams for recycling that include the classification of plastics, paper, cardboard, beverage cartons, glass and / or metals, (3) waste derived fuel,
    25 (4) optional preparation of fermentation products from glucose, and (5) optional preparation of synthesis gas from one or more streams rich in isolated organic compounds.
    More particularly, the apparatus, methods and procedures of the present invention
    30 provide an effective classification of MSW to provide a stream of high purity clean bio-waste comprising cellulose and low concentrations of enzymatic and fermentation inhibitors, such as clay and inorganic salts, which is suitable for conversion into monosaccharides and optional fermentation products at an acceptable rate and commercial performance. The present invention further provides
    35 streams of recyclable plastics that are classified according to the type of plastic, such as polyethylene terephthalate ("PET"), high density polyethylene ("HDPE") and poly (vinyl chloride) ("PVC"). The present invention also additionally provides a residual solid fuel ("CSR") having a caloric value of at least 17 megajoules per kilogram which is

    stream of fine material 102 and a stream of flat material 105. Compared to the through stream 21, the stream of rolling stock 101 is enriched in bottles and cans, the stream of thin material 102 is enriched in organic and inorganic compounds, and the Flat material stream 105 is enriched in paper and cardboard. The
    5 stream of fine material 102 is combined with the through stream 12 to form the stream of raw cellulosic bio-wastes 15.
    As a further reference to Figure 1, the crude cellulosic bio-waste stream 15 is fractionated into a trommel 30 having openings of about 5 mm to about 20 mm to form a through current 31 and a sinking current
    35. The through stream 31 predominantly comprises inorganic material and organic material, where the inorganic material is in excess. In some aspects of the present invention, the through current 31 is purged from the process. The sink current 35 is enriched in organic material such as cellulose, hemicellulose and starch, but additionally comprises some amount of inorganic materials and recyclable material comprising plastic. The sink current 35 is fractionated by density separation 150 to form a stream of dense material 151 enriched in inorganic compounds when compared to the sink current 35 and a stream of light materials 155 enriched in organic material compared to the stream of sinking 35. 20 The stream of light materials 155 is divided into a barrel 40 that has openings of about 20 mm to about 30 mm to form a clean bio-waste stream 45 and a sink current 41. The sink current 41 is fractionated by optical classification 170 to recover the stream rich in organic material 171 and a recycled stream 175 that is enriched in recyclable material that
    25 includes plastic. The particle size of the stream rich in organic material 171 is reduced in a mill 180 to form the bio-waste stream 181 that is combined with the clean bio-waste stream 45 to form a clean bio-waste stream 47 for conversion into monosaccharides.
    30 As a further reference to Figure 1, the rolling stock stream from the ballistic separation 101 and the stream rich in recyclable materials 175 are fractionated by optical sorting and manual sorting 110 to form a series of recovered streams 111 including plastic films 112, PEAD 113 plastic, PET 114 plastic, mixed plastic 115, beverage cartons 116, paper / cardboard 117 and CDR 120 current.
    35 flat material stream by ballistic separation 105 is optionally fractionated by optical classification 210 to form the CDR 215 current and the paper and cardboard current 211. The CDR streams 120, 202 and 215 combine to form the CDR 205 current that is processed by conditioning CDR 220 described herein

In additional relation to Figure 2, the raw cellulosic bio-waste stream 15 is divided into a trommel 50 which is a two-stage trommel having a first section with openings of about 20 mm to about 30 mm and a second section that it has openings of about 40 mm to about 60 mm to form a first through current 51 that crosses openings of 20 mm to 30 mm, a second through current 55 15 that crosses the openings of 40 mm to 60 mm and a sink current 56 where The first through-flow 51 is enriched in inorganic compounds compared to the second through-stream 55. In some aspects, the thromel 50 can comprise two single-screen trommels arranged sequentially. The through stream 51 is divided into a trommel 30 having openings of about 5 mm to 20 about 15 mm to form a through current 31 and a sinking current
    35. The through stream 31 predominantly comprises inorganic material and organic material, where the inorganic material is in excess. In some aspects of the present invention, the through current 31 is purged from the process. The sink current 35 is enriched in organic material such as cellulose, hemicellulose and starch. The sinking current 35, the passing current 55 and the sinking current 56 are fractionated by X-ray separation 160 to form the bio-waste stream 165 having an average particle size of less than about 25 mm and the bio-waste streams 161A and 161B, each having a particle size greater than about 25 mm, and the current 162 which is enriched in inorganic material if 30 is compared with any of the streams 161A, 161B and 165. As graphically depicted in the Figure 6, X-ray separation 160 may comprise 3 stages of X-ray separation, 160A to process stream 35 to form a stream rich in bio-waste 165 and a stream rich in inorganic material 162, 160B to process stream 55 to form a stream rich in bio-waste 161A and a stream rich in
    35 inorganic material 163, and 160C to process stream 56 to form a stream rich in bio-waste 161B and a stream rich in inorganic material 164. The particle size of the streams of bio-waste 161A and 161B is reduced in a mill 180 to form the mill 180 bio-waste stream 181 that is combined with the bio-waste stream 165 to
