A process is described for using tropical fibers to recover spilled oil, gasoline, kerosene, hydrocarbons, pentachlorophenol, creosote or other hazardous liquids from land or water. The sorbent fiber material is produced from agricultural byproducts from cultivation of banana, plantain, cavendish plant, pineapple, coconut, palm, or other tropical fruit bearing plants. The sorbent fibers are produced by separating the raw plant materials; washing the separated fibers in a solution of 1% alum; pressing the fibers to extract liquids and natural juices; further separating the fibers by beating or agitating; and drying the fibers. The sorbent fibers have a water and natural liquid content of less than 10% by weight and may be applied to the surface or periphery of an oil or chemical spill, whereupon they will sorb the oil or chemical. Once the oil or chemical is sorbed the fibers may be collected and the oil or chemical may be partially recovered by compressing the fibers. The fibers may be disposed of by landfilling or may be thermally treated. When thermally treated in a boiler or furnace, the liquid laden fibers may also be a valuable source of fuel.

A multi-layer protective wrap system for wood or metal pilings and poles comprising multiple organic polymer layers (an inner seal wrap, an optional foam conformation layer, and an outer compression shell) secured to the pilings by a bar-and-band system provides resistance to decay, thereby extending the life of pilings / poles in both new and retrofit installations. The 2- or 3-layer wrap system not only extends the life of pilings / poles by protecting them from new infestation by organisms, but also starves existing organisms of the oxygen they require to survive. In addition, because the inventive wrap system seals the piling / poles, it prevents leaching of creosote or other protective coating materials into the environment, reducing the threat of toxicity. This permits industry current standard practice of impregnating pilings with creosote to act as a third or fourth layer inside the 2-3 layers of the inventive wrap system.

This invention is based upon the discovery that activated carbon can be used to sequester polycyclic aromatic hydrocarbons that may be present in asphalt and creosote compositions. The treatment of asphalt and creosote compositions with activated carbon accordingly reduces the level of free polycyclic aromatic hydrocarbons in such compositions by sequestering them therein or removing them from the composition. After being sequestered the polycyclic aromatic hydrocarbons remain trapped in the asphalt or creosote composition, and are not available to the environment during normal processing into useful industrial products. This sequestration reduces the risk of exposing humans and the environment to the polycyclic aromatic hydrocarbons which would otherwise be free to migrate from the asphalt or creosote product during manufacturing and the service life of the product. In other words, the polycyclic aromatic hydrocarbons are absorbed onto the activated carbon and are not available for bioaccumulation from the environment.
