Abstract:
1. A method for recovering recyclable materials from mixed solid waste stream, comprising: providing a mixed solid waste stream that includes a mixture of mixed wet organic waste materials, mixed dry organic waste materials, and mixed inorganic waste materials; fractionating the mixed waste stream by size by performing an upper size cut and a lower size cut to produce a sized waste stream, the sized waste stream having a size range where the ratio of an upper cut-off to a lower cut-off is less than 8; fractionating the sized waste stream by density using at least three density separators in parallel and/or in series to produce at least three separated waste streams including at least a separated mixed wet organic stream enriched in mixed wet organics, a separated mixed dry organic stream enriched in mixed dry organics, and a separated mixed inorganic stream enriched in mixed inorganic materials; and recovering at least one product from each of the at least three separated waste streams or a downstream portion thereof.
