Abstract
Abstract. The production and use of plastics is increasing rapidly as
they are widely used in packaging, construction materials, furniture, foils,
etc. As a consequence of their widespread use and often disposable
nature, vast streams of plastic waste are continuously generated, a
considerable fraction of which are combusted in households worldwide. In
this paper, various types of commonly used plastics (PE, PET, PP, PU, PVC,
PS, ABS) as well as treated wood samples (LDF, low-density fibreboard) and firewood were combusted
separately in a test stove under controlled conditions. The particulates
emitted during the combustion test were collected on filters, potential
tracers for each waste type were identified by GC-MS, and their relative
abundances were determined. The emission factor of 1,3,5-triphenylbenzene
was found to be higher for polymers containing aromatic rings in their
structure. The application of terphenyls and quaterphenyls as tracer
compounds has also been investigated. The trimer of styrene was found to be
a potential tracer for the combustion of polystyrene and/or styrene-containing copolymers. Novel tracers were proposed for the burning of PET
and furniture plates (LDF), which are among the most widely used waste types
burned in households.
