Embodiment Construction

[0021] In order to provide a more precise understanding of the subject matter of the present invention, the following approaches are set forth. Features of the invention are illustrated with reference to the figures, wherein like reference numerals are used to designate like parts throughout the figures.

[0022] Figure 1 illustrates the flow chart for sorting MSW into various types of materials. For example, MSW can be transported from a delivery truck to a facility where the system of the present invention is placed, via various equipment. A receiving hall can be provided so that delivery trucks can store MSW in a designated area so that the MSW can then be removed by, for example, a front end loader, away from sloped ground connected to the designated area. Bins or lift bins for bulky waste and hazardous materials are available in the receiving hall.

[0023] The MSW (100) is loaded into the feed hopper of the bag opening machine (110) from eg a front loader, for example,...

Abstract

A method, and associated system, of sorting municipal solid waste into types of materials, the method including the steps of: sorting the solid waste into an oversize fraction, a midsize fraction and an undersize fraction; using at least manual-based, density-based, further size-based and metal-based sorting means to obtain a partial oversize fraction, a first partial midsize fraction and a second partial midsize fraction; combining the partial oversize fraction and the first partial midsize fraction to produce an oversize-midsize combined fraction, and combining the undersize fraction and the second partial midsize fraction to produce an undersize-midsize combined fraction; and, using further sorting means to further sort the oversize-midsize combined fraction and the undersize-midsize combined fraction into types of materials.

Description

technical field [0001] The present invention relates to systems and methods for sorting solid waste materials, in particular, systems and methods for sorting municipal solid waste to enhance the recovery of recyclable, reusable materials from municipal solid waste, or useful Resources. Background technique [0002] Traditionally, municipal solid waste ("MSW") (ie, bagged or non-bagged MSW materials) has posed a disposal challenge. This difficulty is exacerbated by population expansion and by the increase in solid waste generated per capita. Typical municipal solid waste includes various components worth recycling. For example, various resources such as organic matter, glass, metals, plastics, paper components, etc. are very valuable in both economical and environmental sense and are worth separating from mixed MSW. [0003] In the past, MSW was disposed of through incineration and / or landfill. With current concerns related to environmental protection, and because of the ...
