“…The result showed that the grafted TiO 2 nanoparticles had a finer dispersion and better compatibility than bare TiO 2 , leading to an increase in mechanical properties of the nanocomposites . Moreover, TiO 2 has a high capacity to adsorb the toxic dioxins generated from the incineration of poly(vinyl chloride) (PVC)/TiO 2 composite waste, followed by catalytic decomposition .…”

To improve the physical properties of plasticized poly(vinyl chloride) (p-PVC), the p-PVC nanocomposites filled with four loading levels (3, 5, 7, and 9 parts per hundred of PVC resin) of either nanosized titanium dioxide (nTiO 2 ) or poly(methyl methacrylate)-encapsulated nTiO 2 (PMMA-nTiO 2 ) were prepared by melt mixing on a two-roll mill, followed by compression molding. The PMMA-nTiO 2 used in this study was synthesized via in situ differential microemulsion polymerization. The resulting PMMA-nTiO 2 exhibited core-shell morphology (nTiO 2 core and PMMA shell) with an average diameter of 42.6 nm. The effects of nTiO 2 and PMMA-nTiO 2 on the tensile properties, hardness, morphology, and thermal stability of the as-prepared p-PVC nanocomposites were then investigated and compared. The inclusion of either nTiO 2 or PMMA-nTiO 2 nanoparticles increased the tensile strength, Young's modulus, hardness, and thermal stability of the nanocomposites in a dose-dependent manner and reduced the elongation at break. However, the elongation at break was still higher than that for the neat p-PVC. Moreover, the PMMA-nTiO 2 nanocomposites had a higher enhancement of the tensile strength, Young's modulus, hardness, and thermal stability than the nTiO 2 nanocomposites at a similar loading level. Hence, the PMMA grafted on the nTiO 2 surface played an important role in toughening and increasing the thermal stability of the nanocomposites owing to the improved miscibility and interfacial adhesion between the encapsulated nanofiller and PVC matrix.

“…Unlike landfilling, incineration provides the following benefits [11,12] while disposing the waste: (1) more than 80% of the volume of the waste is reduced during incineration which completes in a relatively short time-scale; (2) the location of incineration facilities can be closer to the waste sources, lowering the transportation cost; (3) a fraction of cost of incineration can be offset by selling heat and power; and (4) air pollution control devices (APCDs) can be used to ensure the emissions of incineration meet environmental regulatory limits. Thus, the current trend is that incineration is gradually taking the place of landfilling [13]. In China, for example, the number of MSW incineration plants increased by 236% while the number of landfilling plants increased by 61% during the years between 2008 and 2016 [3,4].…”

“…The contamination problem caused by polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) has been drawing much attention since PCDD/Fs were detected in the fly ash from a MSW incinerator in 1977 [14]. Though there has been a lot of study on the control of PCDD/F emission [15,16], MSW incineration is still one of the significant sources of PCDD/Fs in the environment [13,17,18]. PCDD/Fs (or, as they are more colloquially mentioned, dioxins) bioaccumulate and biomagnify through food webs into different individuals (including human beings) because of their persistence in the environment and being highly lipophilic [18].…”

Landfilling, a traditional and major method for municipal solid waste management, is gradually being taken place by incineration. However, the contamination problem caused by polychlorinated dibenzo-p-dioxin and dibenzofuran (PCDD/F) emissions from incineration has also brought much concerns. Traditional offline method based on high-resolution gas chromatography coupled with high-resolution mass spectrometry for the determination of PCDD/F emissions is expensive, infrequent and time-lagging. Use of PCDD/F indicators to achieve fast indirect measurements for PCDD/Fs is a much more promising method. Six categories of potential PCDD/F indicators are discussed in this paper: CO, total hydrocarbons, specific PCDD/F congeners, polycyclic aromatic hydrocarbons, chlorophenols and chlorobenzenes. Their performance as PCDD/F indicators are verified in the following criteria: (1) structural similarities; (2) known mechanistic arguments; (3) known correlation values from the literature and (4) detectability. Comprehensively considering the four factors, chlorobenzenes may be the best suitable PCDD/F indicator. One analytical method based on Photon Ionization coupled with Time-of-Flight Mass Spectrometry has been proved effective for the online/atline measurements for PCDD/F indicators for the prediction of TEQ in incineration process. Moreover, thermal desorption and gas chromatography can be applied to provide extra separation and concentration for very complex matrices with extremely low concentrations.

“…This won"t produce any monomers, but it will produce heat, steam or energy. In this process incomplete incineration is a major problem, which produces many persistent organic pollutants, for example dioxins (Kim et al, 2008) and polycyclic aromatic hydrocarbons (Li et al, 2001) as byproducts. This leads to demands of high cost pollution control, reducing any profits.…”

The consequences of plastic debris in the marine environment were reviewed, and possible solutions were presented. The extent of marine plastic debris-related problems surpasses many other marine problems, as plastics may be transported globally and no unaffected areas seem to exist. Many animal species are in risk, most commonly studied are the effects on marine mammals and seabirds. Marine plastic debris creates new concerns such as entanglement, ghost fishing, and impaction of digestive tracts in animals. It also increases the severity of already existing concerns such as transport, exposure and uptake of organic pollution, with reduced fitness and impaired reproduction and increased mortality rates as consequences. To alleviate the problems, reducing the extent of marine plastic pollution is critical. Possible methods were identified as collecting and incentivizing recycling of marine plastic debris; redirecting production from petroleum plastics to biodegradable varieties; increase public awareness to reduce marine littering; stricter enforcement of current legislation as well as implementation of stricter legislation and harsher penalties for breaking it.Asian J. Med. Biol. Res. September 2018, 4(3): 233-241
