Problems solved by technology

[0012] However, the energy balance of many recirculation systems is below average or, in some cases, negative
For example, many recycling systems tend to misdirect recyclable material, which reduces the efficiency of downstream processing and wastes some of the valuable energy and / or material that could be recovered from recycled waste.
In other cases, the process of recycling, transporting, and reusing reusable materials is so inefficient that the energy consumed by these processes is greater than what could be saved by simply dumping waste into landfill and using the raw materials to make new products

Embodiment Construction

[0030] I. Introduction and Definitions

[0031] Municipal Solid Waste ("MSW") (i.e., waste or garbage) is a category of waste material that consists primarily of household waste, sometimes with additional Commercial waste collected by the unit. They are in solid or semi-solid form and generally do not include industrial hazardous waste.

[0032] MSW contains many components that have energy values ​​if properly separated, isolated and processed. For example, MSW can contain large quantities of organic waste materials (e.g., food and kitchen waste, green waste (e.g., yard clippings, plants, vegetation, branches, lawns, etc.), paper, textiles, rubber, plastics, and Recycled materials (such as cardboard and some paper products, glass, ferrous, aluminum and other non-ferrous metals, and certain plastics), and inorganic waste (such as concrete, soil, rocks, and debris). Rather than grouping nearly all MSW categories together and sending them to landfill or incineration, any and ...

Abstract

A method and system for separating mixed waste into a wet organic fraction, a dry organic fraction and an inorganic fraction by: (i) shredding the mixed solid waste; (ii) sizing the shredding stream fractionation to produce two or more particle size waste streams; (iii) processing one or more of the particle size waste streams using density separation to produce an intermediate waste stream, and (iv) recovering homogeneous waste streams from the intermediate waste streams Products (for example, reusable materials or organic fuels).
