Carpet Fiber Dusts

The carpet industry in the United States produces about 1 billion square meters of carpet per year. Of this, approximately 70% is used to replace existing carpet this translates into 1.2 million t (1.32 million T) of carpet waste produced annually [49]. Additional wastes produced by the carpet making industry increase the total amount of waste fibers to an estimated 2 million t (2.2 million T). Several research efforts are addressing ways to include these waste fibers in both asphalt pavements and Portland cement concrete. [Pg.67]

Air-cooled blast slag (ACBFS) - If the liquid slag is poured into beds and slowly cooled under ambient conditions, a crystalline structure is formed, and a hard, lump slag is produced, which can subsequently be crushed and screened [Pg.68]

Coal bottom ash (BA) and boiler slag (BS) are the coarse, granular, incombustible by-products that are collected from the bottom of furnaces that burn coal for the generation of steam, the production of electric power, or both. The majority of these coal by-products are produced at coal-foed electric utiUty generating stations, although considerable BA and/or BS are also produced from many smaller industrial or institutional coal-fired boilers and from coal-burning independent power production facilities [50-57]. The type of by-product (BA or BS) produced depends on the type of finnace used to burn the coal. The main differences between coal bottom ash and boiler slag are summarized in Table 3. [Pg.68]

Bottom ash (BA) - The most common type of coal-burning furnace in the electric utility industry is the dry, bottom pulverized coal boiler [Pg.69]

Boiler slag (BS) - Wet-bottom boiler slag is a term that describes the molten [Pg.69]

Closed hose. Upright vacuums rely on the hose to suck air from the cleaning head into the dirt collector. Closed hoses have less air to pull dirt and dust from carpet fibers, upholstery, and other surfaces. Canister vacuum cleaners are particularly tricky because the hoses are often longer. It goes without saying Air cannot flow through a closed hose. [Pg.181]

The most frequently used methods for sampling indoor surface dust for SVOC/ POM analysis is simply to use dust from a vacuum cleaner dust bag, see for example, Krause, Chutsch and Englert (1989), or a special vacuum cleaner mouthpiece containing a filter, see for example, 0ie, Hersoug and Madsen (1997). Both the mouth-piece and the filter should be cleaned prior to use. It must be assured that the SVOCs and POMs of interest are quantitatively captured by the filter (e.g., phthalates are quantitatively captured by quartz fiber filters (Clausen and Wolkoffi 1997b)) and that the vacuum cleaner exhaust does not contaminate the samples with for example, phthalates. However, the vacuum cleaner sampling method is probably very dependent on the sampling conditions (e.g., carpet or hard floor... [Pg.27]

The term static electricity is understood to mean a high-voltage low-current electrical discharge in the form of often visible sparks caused by contact and separation of dissimilar nonconductors and also of insulated conductors of electricity. It is nowadays in constant evidence in connection with synthetic plastic films and fibers and also with wool and silk used in clothes, carpets, upholstery materials, etc. In the case of dusts, static electricity is created by the movement of the particles, and certain sensitive metal powders can ignite by being poured from a sheet of paper or plastic film. Low relative humidity favors buildup of static electricity. [Pg.39]
