U.S. production of bromine trifluoride is several metric tons per year mostiy used in oil-weU cutting tools. Air Products and Chemicals, Inc. is the only U.S. producer. The 1992 price was ca 80/kg. 

About 800 million metric tons of raw steel is produced annually throughout the world. Its usehilness is enhanced by the fact that it is inexpensive. The price as of the mid-1990s ranged from ca 440/kg for the common grades to several dollars per kg for special steels such as certain tool steels. Prices have remained relatively constant since the early 1980s. 

Annual world production of titanium carbide is thousands of metric tons. It is manufactured mainly in-house by cutting-tool manufacturers by the reduction of titanium dioxide with carbon ... 

This technique is also called nonaxisym-metric blow molding. In conventional EBM the parison enters the mold rather in a straight tube. In 3-D BM the parison is laid or oriented in the mold prior to closing. It is manipulated in the tool cavity providing complex geometric products that can have... 

Whilst LCA is a powerful tool, which will become increasingly useful, as it is refined and becomes more objective, its complexity and cost, and the length of time taken to carry out a full analysis make it an impractical tool to use on a day-to-day basis for research and development chemists and chemical engineers. What is really required for most practising technologists is a simple set of metrics to aid the decision-making process involved in choosing one synthetic route or product over another. 

In this chapter, we focus on strategies, tools and metrics that help chemical choosers to green their chemical product inventories and to benchmark progress. The term chemical chooser applies to those who purchase chemicals for use in the development of formulated products or those who purchase formulated chemical products for use in their use in activities such as maintenance, repair and operations. Most product manufacturers are chemical and material choosers in contrast to chemical or raw material manufacturers who process, synthesize and supply chemicals as raw materials. 

Strategies, tools and metrics support the process of change toward the adoption of green chemical inventories at each step. 

Once the inventory of chemicals in raw materials or products is complete, the next step on the path to integrating green chemical inventories is to assess and evaluate the associated hazards. Using the following rather simplistic distinctions helps to assess and evaluate hazards. Each of these distinctions brings with it a different set of strategies, tools and metrics. 

In this chapter we describe strategies, tools and metrics that are currently and publicly available for advancing green chemical inventories in products and processes. The science of green chemistry will continue to advance as will the frameworks, strategies, tools and metrics that support understanding, implementation and reporting.
