For phase II, no specific process validation activity is required unless process improvement changes potentially affect prior phase I validation work [14], Assay validation efforts should continue, however, so assays are ready for phase III validation and process development should be finalized before phase III [14], Most process and assay validation activities begin in phase II and often extend far into phase III [4], occurring in parallel with phase II and phase III clinical material production [3], Intensive process characterization often is delayed until after completion of phase II studies to conserve resources [65], About 12-15 months are allowed for its completion before the process validation runs [65], To minimize risk, if all phase II clinical data are not available, these activities can be ramped up slowly over the first few months. Raw material vendor audits should be performed between phases II and III before the manufacturing process is fixed [47]. 

Intensive research efforts have been focused on protecting the viability of probiotic cultures both during product manufacture and storage, and through the gastric transit until the target site is reached. Protection may be achieved by several ways, among them, encapsulation. 

Some models combine material manufacture and product manufacture into one stage [2]. At every stage in the life cycle, energy and material inputs are considered, as well as waste emissions. Therefore, a very clean process to manufacture a chemical may be considered less desirable, from an LCA standpoint, if a raw material (or a raw material for a raw material) is manufactured using a process that is very energy intensive or that produces large amounts of waste. 

The leading states in milk production in decreasing order are Wisconsin, Minnesota, New York, California, and Pennsylvania. These states produce - 45% of the U.S. milk supply. Less than 5% of the total production is used on farms and the remainder is sold for commercial purposes. Whereas milk and cream were formerly shipped in 19-, 30-, or 38-L cans from the farm to the plant, in the 1990s most commercial production, particularly for fluid milk, is moved in bulk from the cows to refrigerated farm tanks to insulated bulk tmck tankers and to the manufacturing plant. The investment in equipment and the cost of hired labor are associated with large, capital-intensive production centers. 

Anhydrous aluminum chloride, AIQ, is manufactured primarily by reaction of chlorine [7782-50-5] vapor with molten aluminum and used mainly as a catalyst in organic chemistry ie, in Friedel-Crafts reactions (qv) and in proprietary steps in the production of titanium dioxine [13463-67-7] Ti02, pigment. Its manufacture by carbochlorination of alumina or clay is less energy-intensive and is the preferred route for a few producers (19). 

Use of mercuric catalysts has created a serious pollution problem thereby limiting the manufacture of such acids. Other catalysts such as palladium or mthenium have been proposed (17). Nitration of anthraquinone has been studied intensively in an effort to obtain 1-nitroanthraquinone [82-34-8] suitable for the manufacture of 1-aminoanthraquinone [82-45-1]. However, the nitration proceeds so rapidly that a mixture of mono- and dinitroanthraquinone is produced. It has not been possible, economically, to separate from this mixture 1-nitroanthraquinone in a yield and purity suitable for the manufacture of 1-aminoanthraquinone. Chlorination of anthraquinone cannot be used to manufacture 1-chloroanthraquinone [82-44-0] since polychlorinated products are formed readily. Consequentiy, 1-chloroanthraquinone is manufactured by reaction of anthraquinone-l-sulfonic acid [82-49-5] with sodium chlorate and hydrochloric acid (18). 

The manufacture of sugar was early understood to be an energy-intensive process. Cuba was essentially deforested to obtain the wood that fueled the evaporation of water from the cane juice. When the forests were gone, the bagasse burner was developed to use the dry cane pulp, called bagasse, for fuel. Bagasse was no longer a waste product its minimal value is the cost of its replacement as fuel. 

Production of carbon electrodes is a capital-intensive business. Two suppHers dominate the prebaked market. Carbon paste producers are more numerous and tend to serve local markets. There is no international standard for the threaded joints on carbon electrodes. Manufacturers of straight pin carbon electrodes have followed the physical specifications adopted for graphite electrodes (37). Unified standards do not exist for pinless joints resulting in limited interchangeability among brands. Electrode diameters are offered in both English and metric sizes with no restrictions on new or unique diameters.
