Wood industries pollutants

Castilla y Leon, and Castilla la Mancha. This part is also the most significant for industrial plants such as biomass crops and oilseed rape. In the southernmost regions of Castilla La Mancha and Catalunya, dry fruit trees and vineyards increase in significance, while the Ebro River delta supports a well-developed rice farming activity. Diffuse pollution originated by pesticides application in the basin has been widely studied [1-3]. A historical pollution from chemical plants manufacturing solvents and chlorinated pesticides in the southern part of the river basin is also well known [4]. Automobile, textile, food, and wood industry as well as mining activities are important in the northern part.

Driers are used in the forest products industry to lower the moisture content of the wood product being processed. Drying of dimension lumber gives it dimensional stability. This type of drying is done in steam kilns and is a batch process. No appreciable pollutants are released.

Impermeable timbers have a good resistance to polluted atmospheres where acid fumes rapidly attack steel. Wood has given excellent service in the buildings of chemical works and railway stations. Permeable wood species and sapwood can suffer defibration problems caused by the sulphur dioxide of industrial atmospheres. Tile battens are particularly vulnerable. The heartwood of Douglas fir, pitch pine, larch, Scots pine/European redwood and many tropical hardwoods give good service in these conditions. 

The paper and allied products industry comprises three types of facilities pulp mills that process raw wood fiber or processed fiber to make pulp paper and board mills that manufacture paper or board and converting facilities that use these primary materials to manufacture more specialized products such as writing paper, napkins, and other tissue products. The process of converting paper is not a source of water or air pollution, as is the case for the first two facilities. This chapter focuses primarily on the greatest areas of environmental concern within the pulp and paper industry those from pulping processes. 

Metal profiles for two sediment cores from the Elizabeth River, VA, USA. Land use along the shores adjacent to collection site PC-1 (Paradise Creek) is primarily industrial and includes oil terminals, shipyard installations, coal transfer facilities, petroleum distribution and shipment operations, and wood treatment facilities. It has been identified as a toxic hot spot by the U.S. EPA. Land-use adjacent to WB-2 (Western Branch) is primarily residential. Excess lopb and profiles for (a) PC-1 and (b) WB-2 profiles. These were used to determine accumulation rates (1.1 to 2.3cm/y at PC-1 and <0.5cm/y at WB-2). Trace metal enrichment factor profiles (see Eq. 28.1 in text) are presented in profiles (c-g) in groups determined by the depth and shape of their concentration peaks. Source From Conrad, C. R, et al. (2007). Marine Pollution Bulletin 54, 385-395. 

Phenolic wastes are one of the most prevalent forms of chemical pollutants in industry today. The major sources of phenolic waste are insulation fiberglass manufacturing, petroleum refineries, textile mills, steel making, plywood, hardboard production, manufacture of organic chemicals, paint stripping, and wood preservatives. Eisenhauer (1964) first studied oxidation of phenolic wastes with Fenton s reagent. It has been demonstrated that the oxidation of phenol involves the intermediate formation of catechol and hydroquinone (Merz and Waters, 1949 Stein and Weiss, 1951 Wieland and...

A large fraction of the chemical industry worldwide is devoted to polymer manufacture, which is very important in the area of hazardous wastes, as a source of environmental pollutants, in toxicology, and in the manufacture of materials used to alleviate environmental and waste problems. Synthetic polymers are produced when small molecules called monomers bond together to form a much smaller number of very large molecules. Many natural products are polymers for example, cellulose in wood, paper, and many other materials is a polymer of the sugar glucose. Synthetic polymers form the basis of many industries, such as rubber, plastics, and textiles manufacture. 

As shown in this table, a zero discharge of process waste-water pollutants is required by EPA for all facets of the timber products industry except wet storage of legs, wet-process fiber products manufacture, and one segment of the wood preserving industry. This requirement, by definition, holds that a zero discharge is "the best practicable technology currently available" by which the affected industries can control pollution.
