“…Of interest is a topical article which raises the possibility of synthesizing sodium polystyrene sulphonate from waste plastic cups and employing it for coagulation and flocculation in wastewater treatment, followed by flotation [56]. The article showed that this process provided better results than several commercial polyacrylamides of non-ionic and anionic character.…”

The use of flotation for the treatment of wastewaters in general, but especially for the removal of oil, grease, general organic matter, and suspended solids, is well established as a low energy process. Polyelectrolytes (PEs) can enhance performance without adding to the solids load that occurs with inorganic additives such as alum. The bridging of pollutants and the attachment of the resulting aggregates to the air-water interface can be effectively carried out with most wastewaters. Hydrophobic modification of the PEs can be useful for difficult species. It should be applied to the flotation of polyfluoroalkyl substances, for example, as they are not amenable to economical conventional treatment. Similarly, the removal of microplastic particles from sewage effluents by flotation could be enhanced.

“…Polystyrene (PS) has, in general, good mechanical, thermal and electrical resistance and low density. Due to these properties, it is used to produce disposable materials such as cups, food trays and plastic bags [18]. Some commercial plasticizer admixtures or superplasticizers incorporated into concrete and mortar have the presence of the sulfonate group, chemically modified group, responsible for the strong interactions with cement particles.…”

“…Polystyrene can be recycled for the production of new materials. In a previous work, the PS obtained from discarded cups and food trays was used for the production of ion-exchange membranes [5], in the water treatment as an auxiliary agent of coagulation, flocculation and flotation for water and wastewater treatment [1,18], and as an admixture to concrete with excellent results, such as increased workability and water reduction, being classified as a superplasticizer admixture [19][20][21]. The objective of this study was to examine the application of sulfonated polystyrene, obtained from discarded plastic cups, as an admixture in mortars.…”

In this work, we studied the addition of sulfonated polystyrene produced from waste plastic cups as an admixture for mortars. Mortars were analyzed with polystyrene content of 0.0; 0.2; 0.6; 1.0 and 1.4% in relation to the cement mass. The influence of polystyrene on the mortars' properties was evaluated by the consistency index, water retention, water absorption, porosity, elasticity modulus, compressive strength, flexural strength, bond tensile strength and microscopy. The increase in the sulfonated polystyrene content decreased the elasticity modulus of the mortar and, despite higher porosity, there was a reduction of water absorption by capillarity. In relation to mortar without admixture, the modified mortar showed an increase in water retention and consistency index, and a large increase in flexural strength and bond tensile strength. The significant increase of bond tensile strength (214% with admixture 1%) highlights the potential of the produced material as an adhesive mortar.
