A method for continuous aeraulic separation of particulate materials consisting of a mixture of particles that is heterogeneous in both particle size and density is provided. The method includes grinding particles of materials, generating a gas stream conveying the ground particles, first aeraulic separation on the gas stream in order to separate the particles it contains into a first fraction consisting of the coarsest particles with variable densities and a second fraction consisting of the finest particles. A second aeraulic separation is performed on the first fraction in order to separate the particles that it contains into a third fraction consisting of the coarsest and/or most dense particles and a fourth fraction consisting of the least coarse and/or the least dense particles. A re-injecting of the third fraction or the fourth fraction at the inlet of the grinding is performed while simultaneous recovery of the second fraction as well as the fourth fraction or the third fraction, respectively, as output products.

A process and system for producing an engineered fuel product that meets customer specifications for composition and combustion characteristics is provided. The engineered fuel product is preferably a high-BTU, alternative fuel that burns cleaner than coal or petroleum coke (petcoke) and has significantly reduced NOx, SO.sub.2 and GHG emissions.

Provided is a sorting method for valuable resources, including a thermal treatment step of thermally treating a target containing valuable resources, to melt aluminum and separate a melt, a pulverizing step of pulverizing a thermally treated product remaining after the melt is separated, to obtain a pulverized product, a magnetic sorting step of sorting the valuable resources from the pulverized product by a magnetic force, and a wind force sorting step of sorting one valuable resource from another valuable resource in the valuable resources by a wind force.

Methods and systems for separating mixed plastic waste are provided herein. The methods generally comprise separating the mixed plastic waste into a PET-enriched stream and one or more PET-depleted streams. The separating may be accomplished using the combinations of two or more density separation stages. Exemplary density separation stages include sink-float separators and centrifugal force separators. The PET-enriched and PET-depleted streams may be recovered and/or directed to downstream chemical recycling processes.
