Polymer industry pollution potential

Can be released as point source pollution during manufacture, transportation and end use. Once APTES is added to a consumer or industrial product, the parent silane reacts with the components of the formulation and is generally present as the parent silane at 0.1-0.2% until after curing (use). After curing the parent silane is consumed into the polymer matrix and no longer exists and greatly reduces potential for consumer or worker exposure. APTES polymerizes during use. 

The author discusses application of ELM, SLM, and polymer inclusion membrane techniques in separation of metal ions (precious metals, Cu, Ni, Zn, Pb, Cd, Cr(VI), Pu, Am, etc.) and organic pollutants (phenols and its derivatives, carboxylic acids, antibiotics, etc.) from wastewaters using laboratory, pilot, and industrial scale modules. Effects of experimental variables upon the solute flux for the various types of liquid membranes are analyzed. The author discusses potential and commercial aspects of hquid membrane technology in wastewater treatment. 

Some polymers from styrene derivatives seem to meet specific market demands and to have the potential to become commercially significant materials. For example, monomeric chlorostyrene is useful in glass-reinforced polyester recipes because it polymerizes several times as fast as styrene (61). Poly(sodium styrenesulfonate) [9003-59-2], a versatile water-soluble polymer, is used in water-pollution control and as a general flocculant (see Water, industrial water treatment Flocculating agents) (63,64). Poly(vinylbenzyl ammonium chloride) [70504-37-9] has been useful as an electroconductive... 

Starch has been one of the first materials extensively studied for its potential as polymer for biodegradable plastics. Impetus in this direction has come from shortage of municipal landfills and pressure to reduce the visual pollution caused by plastic residues abandoned in the landscape. Despite considerable interest from both the academic and industrial sectors, production of commercially viable materials has been delayed for technical and economic reasons. The former are inherent to the chemical structure of starch itself the vast quantity of internal hydrogen bonds hampers thermoplastic behaviour, and the hydrophilic nature of the polysaccharide translates into sensitivity to the environmental humidity that, in its turn, may affect the mechanical properties of the material. 

Chapter 1 is a comprehensive review of the polymer PHB, poly(hydroxybutyrate), which is new to industrial manufacturing but is a naturally occurring substance. It has potentially valuable properties but has excited interest especially because it is biodegradable. It may, therefore, provide one means of reducing environmental pollution. 

We are exploring synthetic transition metal catalysts in the heterogeneous aqueous environments of polymer colloids. Potential uses of such catalysts are decontamination of water and industrial organic chemical syntheses. Initial efforts are focused on oxidations. Organic pollutants in water can be difficult to degrade if they lack polar functional groups. 

Nowadays, petroleum-derived polymers are the most widely used materials in the packaging industry. However, there are important problems related with their use, such as no renewability, high costs, and potential pollution they can create (Thakur et al. 2012a, b, c, d, e). The extensive degradation time associated to these...
