Converting waste polystyrene into a polymer flocculant for

We have succeeded in converting waste polystyrene from electrical appliances into a polymer flocculant for treating some kinds of wastewater after chemical modification. Waste polystyrene, such as polystyrene foam and additive-containing TV cabinets, was converted into a water-soluble polymer, polystyrene sulfate (PSS), and PSS of various degrees of aqueous viscosity was obtained by

Potential uses and value-added products derived from waste

While the recycling of waste PS into construction material and artefacts is gaining acceptance in SSA, its chemical conversion into high value products is lagging behind. Future research is likely to pursue chemically converting waste PS into flocculants for heavy metal removal from solution, and for other applications like paints and adhesives.

We have developed a method of recycling technology to use scrap plastic for cleaning waste water from a semiconductor plant. This is a technology which transforms polystyrene waste from electrical products which contain additives such as coloring materials into water-soluble polymers by sulfonation. These polymers work as a flocculant for the disposal of waste water from factories. A new

Ni Ink-Catalyzed Conversion of a Waste Polystyrene–Sugar

The disposal of organic waste materials such as polymers is a serious problem to natural ecosystems as some of them can be non-biodegradable and potentially toxic. Thus, there is immense interest in developing processes that convert waste polystyrene into useable carbon. In this work, we developed a unique approach for obtaining graphitic carbon from waste polystyrene as a raw carbon source

An attempt has been made to recycle Styrofoam waste to a novel functional polymer, Phenyl thiosemicarbazone surface (PTS). Polystyrene (PS) obtained from Styrofoam waste was acetylated and then condensed to PTS by reacting it with 4-Phenyl-3-thiosemicarbazide ligand and characterized by FT-IR spectroscopy and elemental analysis.
