Abstract
The purpose of this work was to characterize, through analytical methods, the physicochemical and toxicological properties between commercial polystyrene and recycled polystyrene. The characterization of the respective products was started with X-Ray Fluorescence (FRX), Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). The in vitro analysis of toxicity in microcrustacean Artemia salina was carried out. The FRX analyzes indicated the presence of chlorine and bromine in the commercial PS. It was observed that recycled PS presents greater thermal stability when compared to commercial PS. No toxicity results were observed for the two types of samples cited in this research.
Highlights
Several sectors have sought alternatives in order to reduce the environmental impacts resulting from industrial production processes, as well as from the use of polymeric products and their disposal (Jesus et al 2019).In addition, with the inherent popular concerns about the recycling theme, followed - the consequent technological innovations that sought, from scientific analyzes and methodologies, to align ideas in search of viable solutions to solve the recurrent problems of the high level of consumption and production of waste of the current society (Araújo et al 2021).Plastics cause a lot of damage to the environment, as they take hundreds of years to undo, causing many problems for people and the environment (Da Cruz et al 2020)
The Fluorescência de Raios X (FRX) analysis showed the presence of chlorine and bromine components in the commercial PS sample, while in the recycled PS sample the mentioned components were eliminated
Recycled PS showed greater thermal stability compared to commercial PS

According to Carvalho & Motta (2019), polystyrene (PS) can be reused from discarded waste, reducing the environmental impact of disposing of this difficult-to-decompose polymer and improving the properties of new or modified materials in which it is incorporated. Polystyrene is a polymer that gives rise to microparticles with a hydrophobic surface, by polymerizing styrene at high temperatures (80 °C) (Severino et al 2011)
