“…Therefore, due to its versatility, polycarbonate has wide ranging applications. It is used in the construction (safety helmets, power tools, windows, skylights, stadium roofs) and automobile industry (headlamp lenses, wheel covers, bumpers), manufacturing of glasses and eye lenses due to its transparent nature, food packaging, table ware (plastic plates, bowls, cups, cutlery), and polycarbonate polyols (coatings, adhesives, elastomers/urethanes) [195][196][197][198][199][200]. Its transparent nature also offers a better alternative to glass, which can easily break and become a danger to people [193].…”

Cumulative plastic production worldwide skyrocketed from about 2 million tonnes in 1950 to 8.3 billion tonnes in 2015, with 6.3 billion tonnes (76%) ending up as waste. Of that waste, 79% is either in landfills or the environment. The purpose of the review is to establish the current global status quo in the plastics industry and assess the sustainability of some bio-based biodegradable plastics. This integrative and consolidated review thus builds on previous studies that have focused either on one or a few of the aspects considered in this paper. Three broad items to strongly consider are: Biodegradable plastics and other alternatives are not always environmentally superior to fossil-based plastics; less investment has been made in plastic waste management than in plastics production; and there is no single solution to plastic waste management. Some strategies to push for include: increasing recycling rates, reclaiming plastic waste from the environment, and bans or using alternatives, which can lessen the negative impacts of fossil-based plastics. However, each one has its own challenges, and country-specific scientific evidence is necessary to justify any suggested solutions. In conclusion, governments from all countries and stakeholders should work to strengthen waste management infrastructure in low- and middle-income countries while extended producer responsibility (EPR) and deposit refund schemes (DPRs) are important add-ons to consider in plastic waste management, as they have been found to be effective in Australia, France, Germany, and Ecuador.

“…Polystyrene (PS) is a widely used polymer type of plastic, being the 6th most demanded plastic in Europe in 2018 and having a similar position on the global demand of plastic in 2015 (PlasticsEurope, 2019; Ryberg et al, 2018). PS is an amorphous thermoplastic made from styrene monomer, which exhibits low specific weight, high transparency and brilliance, absence of color, low shrinkage, chemical inertness, and a simple production process (Begum et al, 2019;Gausepohl and Nießner, 2001). It can be found in the market under different varieties, such as general-purpose polystyrene (GPPS), high impact polystyrene (HIPS), expanded polystyrene (EPS), and extruded polystyrene (XPS).…”

“…It can be found in the market under different varieties, such as general-purpose polystyrene (GPPS), high impact polystyrene (HIPS), expanded polystyrene (EPS), and extruded polystyrene (XPS). Because of its characteristics, PS has been widely used as a packaging material for food and non-food applications, as a building insulator, on the manufacture of household items, on aquaculture, and on the electric, electronic and automobile industries (Begum et al, 2019;Chen et al, 2018;Gausepohl and Nießner, 2001;Gu et al, 2017).…”

Plastic pollution is one of the major issues impacting on the marine environment. Plastic polymers are known to leach industrial chemicals and associated contaminants. In this review, we focused on assessing the global distribution and concentration of two polystyrene-derived contaminants, hexabromocyclododecanes (HBCDs) and styrene oligomers (SOs), in marine sediments and seawater. Overall, most of the studies were carried out in Asia, North America, and Europe. Relatively high concentrations of these contaminants are generally attributed to the proximity of urban cities, plastic industries, polystyrene pollution, and aquaculture. Moreover, the concentrations in sediments are many times higher than in seawater. HBCDs were found to be a negligible risk to marine biota when compared to the ecotoxicological endpoints. However, realistic concentrations of SOs could compromise the wellbeing of certain species in highly polluted sites. The future perspectives and research were discussed.

Precipitation or coprecipitation of polyelectrolytes has been largely investigated. However, the precipitation of polyelectrolytes via addition of charged and non‐charged surfactants has not been systematically studied and reported. Consequently, the aim of this work is to investigate the effect of different surfactants (anionic, cationic, non‐charged and zwitterionic) on the precipitation of cationic and anionic polymethylmethacrylate polymers (Eudragit). The surfactants effect has been investigated as a function of their concentration. Special attention has been dedicated to the CMC range and to the colloidal characterization of the formed dispersions. Moreover, the effect of salt (NaCl) and pH was also addressed. It is pointed out that non‐ionic and zwitterionic surfactants do not interact with charged Eudragit E100 and L100. For oppositely charged Eudragit E100/SDS and Eudragit L100/CTAB, precipitation occurs, and the obtained dispersions have been characterized in terms of particle size distribution and zeta potential. It was established that the binding of SDS molecules to Eudragit E100 polymer chains is made through the negative charges of the surfactant heads under the CMC value whereas binding of CTAB to Eudragit L100 chains is made at a CTAB concentration 5 times above its CMC. For Eudragit E100/SDS system, a more acidic medium induces aggregation. A same result was observed for the Eudragit L100/CTAB at a more basic pH. Moreover, it was observed that increasing salt concentration (higher than 100 mM) led to aggregation as generally observed for polycations/anionic surfactant systems.
