Recycling applications

Recycle of HBr to bromine is highly desirable both from an economic and an environmental standpoint. Catalytic oxidation offers the potential to recycle HBr from contaminated waste streams to bromine. We have demonstrated that the oxidation catalyst is stable against deactivation by a wide range of contaminants found in waste HBr streams. Strategies to deal with the contaminants will depend on the recycle applications in which the catalytic oxidation unit serves. 

Plastic and Metals Recycling Electrostatic separation has been increasingly applied to recover nonferrous metals from industrial plastics (telephone and communication scrap). It also is an important step in the recycling of beverage bottles to reject any remaining nonferrous metals. Both of these recycling applications make use of roll-type ion-bombardment separators (Fig. 19-6lb).

From the first recycling applications conducted in the United States, it was reported that the recycled asphalt production cost, when produced in a stationary plant, ranged between 10% and 39%, depending on the project (Finn 1980 TRB 1978). Similarly, when recycling was conducted in situ, the total reduction in construction cost was on the order of 33%.

To identify areas of potential recycling applications, the easiest is to examine the various uses of cobalt. The amount of cobalt used in various applications obviously varies with time with new applications being developed and other becoming obsolete. 

MF is also sometimes employed for recycling of CMP wastewater. In recycling applications where the objective is to recover the water, the MF permeate may undergo additional treatment by reverse osmosis to recover a purified water recycle stream. Alternatively, the reject from a membrane filter can be employed as a means of recovering and recycling the slurry itself (Testa et al., 2011, 2014).
