In recent years, the construction of a "circular economy" that aims to achieve economic growth while securing resources and decarbonizing has been attracting attention. Material recycling of plastics is an important means, however in order to circulate recycled resins that have value as materials, it is necessary to clarify the substances contained in them. However, since chemical information is lost in recycled resins, comprehensive analysis of additives by non-targeted analysis is required. In this study, by combining the Heart-Cut pyrolysis GCMS and Direct Analysis in Real Time (DART)-MS, additives were comprehensively analyzed with a sample amount of about 10 mg for polypropylene (PP) recycled from market collections. We tried to develop a method that can be evaluated rapidly.
