This chapter examines the following concepts: problem of emissions and how to deal with them, governmental regulations, material storage, contamination in the plant, disposal, waste, and recycling, and factory simulation. Some aspects of the information in this and succeeding sections have already been discussed in earlier chapters. However, because this chapter may be examined by itself and because a stronger focus is needed on some of the points, the material is treated here again in some detail. New material is also presented, which is unique to this chapter. Another aspect of composites manufacturing that has some governmental control is the storage of hazardous or potentially hazardous materials. Great caution should be exercised in disposing of any liquid materials. The efficiency of factory operations can mean the difference between profit and loss for a company. If the manufacturing process is poorly laid out or the plant is messy and dirty, the result is not just contamination and poor quality.
