Continuous growth in the production of plastics, as well as an increase in plastic waste, which may be a source of environmental pollution, are of great importance for modern science. Nowadays, composites containing unsaturated polyester resin (UPR) are widely used in the shipbuilding, rail, aerospace, automotive, and construction industries due to their high mechanical properties and chemical resistance. However, their high flammability and toxic smoke emission during fires pose a serious threat not only to human health and property but also to the environment. A proper level of fire safety can be achieved by the use of flame retardants (FRs). Although limitations on FRs have been imposed, 39% of their global production accounts for FRs that pose a threat to human health and the environment. For this reason, in recent years, the replacement of halogenated and organophosphorus FRs, and others has led to the development of more sustainable FRs of natural origin. Moreover, it is advisable to look for other sources of non-toxic and effective FRs, along with their economic availability. The aim of the study is to analyse the influence of L-arginine salts with high nitrogen content on the thermal degradation and emission of gaseous combustion products of UPR. Based on the conducted research and the analysis of volatile products changes in the degradation process of modified UPR are discussed and the most promising and efficient compounds in terms of enhancement of flame retardancy of UPR are proposed.
