    Abstract

    The role of pentachlorophenol treated wood for emissions of dioxins into the environment

    This study has investigated the part played by pentachlorophenol-treated wood in emissions of dioxins into the environment. A thorough inventory of the use of different products treated by different methods has been carried out, in addition to chemical analyses of four different treated wood products. The tested products were an indoor panel from a swimming pool in Finspång, Sweden, a utility pole from Oregon in the USA, and a field test stake exposed outdoors in Denmark since 1968, looking at both the part above ground and that in the ground.

    Between 1956 and 1978 approximately 640 tonnes of pentachlorophenol were used in Sweden for pressure impregnation of wood products, and 1000 – 1500 tonnes for diptreatment of freshly sawn wood before further storage or transport. A further 200 tonnes or so were used for consumer products (DIY), and approximately 15 tonnes for remedial treatments.

    The estimated amount of dioxins (I-TEQ) in the Swedish environment today due to the use of chlorophenol-treated wood products is estimated to be between 0,4 and 3,7 kg. The considerable uncertainty is due to the wide variation in analytical data. In addition, a quite high figure has been used to approximate the amount of wooden products still in use, in order to avoid underestimation.

    Dioxin sources resulting from the use of chlorophenol-treated wood products are diffuse and scattered, and thus difficult to clean up efficiently. The most efficient method of reducing dioxin emissions is to ensure that all demolition wood is destroyed in a modern incinerator with efficient air pollution control systems.

    Key words: Preservative-treated wood, pentachlorophenol, PCP, dioxins, emissions

    Textilåtervinning: Tekniska möjligheter och utmaningar2015Report (Other academic)
    Abstract [sv]

    I regeringsuppdraget ingår också att bedöma vilken typ av materialåtervinning av textilier som kan komma till stånd på kort och lång sikt och hur det bör påverka utformningen av insamlingssystemet. Naturvårdsverket gav därför i uppdrag till SP Sveriges Tekniska Forskningsinstitut att kartlägga befintlig teknik och aktuella utvecklings- och forskningsinitiativ samt att utföra en kvalificerad bedömning om möjlig framtida teknisk utveckling inom området textil materialåtervinning.

    I forskarstudien analyseras tekniska och miljömässiga utmaningar samt potentialen för textilåtervinning. Utifrån textilåtervinningens tekniska och miljömässiga förutsättningar ges rekommendationer för hur utmaningar kan bemötas och miljövinsten med materialåtervinning optimeras. Bedömningarna och rekommendationerna baseras på livscykelanalyser av olika scenarier för hur återvinningen kan ske.
