New Separation Technique for Waste Plastics

Tribo-aero-electrostatic Separation of Micronized Waste Plastics

Electrostatic separation of granular plastics mixtures has become a wellestablished technology, with industrial applications in the area of waste electric and electronic equipment (WEEE) recycling. The aim of this work is to validate the feasibility of selectively sorting of micronized waste plastics in a two-rotating-disks-type tribo-aero-electrostatic separator. The experiments are carried ou...

Waste-Wood-Derived Fillers for Plastics

Filled thermoplastic composites are stiffer, stronger, and more dimensionally stable than their unfilled counterparts. Such thermoplastics are usually provided to the end-user as a precompounded, pelletized feedstock. Typical reinforcing fillers are inorganic materials like talc or fiberglass, but materials derived from waste wood, such as wood flour and recycled paper fiber, are also effective...

Heavy Media Column Separation: a New Technique for Petrographic Analysis

A heavy media column is used for the separation of the mineral fractions of a sample. Thus the directly weighed per cent of the mineral composition of the rock or ore sample is accomplished. ttre teihnique may be applied to the concentration of a particular species, e,ren i.r trace amounts, for further mineralogical studies or for practical commercial metallurgical mineral beneficiation purposes'

A new technique for the separation of radiophosphorus from sulfur

A new approach to the separation of radiophosphorus from sulfur has been found which makes a unique use of ion exchange resins. Separations using resin columns are especially suited to problems involving radioactivity since they require a minimum of handling.
