Popis: This paper reports on the methodology to collect volatiles from the hot-wire cutting of expanded polystyrene. Analytical scale pyrolysis was used to model the conditions in the field. It appears that gas chromatographic profiles are little affected by the presence or absence of flame retardants. Pyrolysis in air or in an inert gas generates very similar pyrograms but the temperature at which pyrolysis takes place is the major factor affecting amount and distribution of volatiles. An experimental design is discussed that permits to model in the laboratory the production of volatiles generated in the field.
