Fluorinated Compounds In Carpets

Symposium paper one of the emerging waste streams that will likely be disposed of in combustors is carpet due to its high heating value and combustibility.

Fluorinated compounds in carpets.

Validating methods under epa s sw 846 to measure certain pfas in groundwater surface water wastewater and solids e g soils sediments and sewage. This paper reports on a study in a 0 73 kw pilot scale rotary kiln incinerator simulator to qualitatively and where applicable. Quantitatively assess the potential for emissions of fluorinated. Cleaning compositions and methods for cleaning carpets and other materials are disclosed.

The extremely strong carbon fluorine bond the strongest in organic chemistry makes them thermally. Myths versus facts long chain highly fluorinated chemicals including pfoa pfos and other c8 compounds were used for decades to give water repellent stain resistant and non stick properties to furnishings carpets food packaging outdoor gear and other products. Perfluorinated compounds pfcs are a class of anthropogenic chemicals incorporated over six decades into a wide range of industrial and consumer use products including surface treatments for carpets and textiles paper and packaging non stick cookware firefighting foams and insecticides. The cleaning compositions contain nanolatexes and the methods for cleaning carpets and other materials use such compositions.

Phased out due to the increasing evidence that bioaccumulation of the chemicals is significant and that in humans the compounds persist with a. In particular has come to be expected in a wide variety of products such as carpets shirts ties and sofas. The compositions may also contain a source of peroxygen bleach and or a fluorinated compound. Because perfluorinated compounds pfcs repel both water and oil they are used as durable repellent treatments for textiles such as outdoor clothes and for home products such as carpets in addition pfcs are widely used in the production of fluoropolymers such as polytetrafluoroethylene trade name teflon which is widely used in coatings for electronic automotive and outdoor products.

Once final it will be included in the sw846 compendium.
