Meat packing plants

There has been only one major use for ozone today in the field of chemical synthesis the ozonation of oleic acid to produce azelaic acid. Oleic acid is obtained from either tallow, a by-product of meat-packing plants, or from tall oil, a byproduct of making paper from wood. Oleic acid is dissolved in about half its weight of pelargonic acid and is ozonized continuously in a reactor with approximately 2 percent ozone in oxygen it is oxidized for several hours. The pelargonic and azelaic acids are recovered by vacuum distillation. The acids are then esterified to yield a plasticizer for vinyl compounds or for the production of lubricants. Azelaic acid is also a starting material in the production of a nylon type of polymer. 

In many process industries, food factories, meat packing plants, textiles plants, commercial laundries and other facilities, wide load swings are the norm rather than the exception, so that maintaining adequate steam purity is often very difficult. 

One of the first significant empowerments of the fledgling FDA was when Congress enacted the Food and Drug Act (also known as the Wiley Act) in 1906 directed to address unhygienic conditions in Chicago s meat-packing plants (see Upton Sinclair s...

Guidelines for Meat Packing Plants, OSHA Publication 3123 (revised 1993). The assessment included a check for potential exposures to communicable diseases from the slaughtered animals. The committee developed a list of questions about safety and health conditions and potential hazards in the plant. To answer these questions, the committee performed a series of walk-throughs coupled with employee interviews. 

Within these general categories of pollutants are included most of the possible sources of recognized water-quality problems. Only bacterial and viral presences fall outside the group of pollutants to which industry contributes materially. (However, even they are not entirely outside the scope of the polluting activities of industry. For example, meat packing plants, and other food processors in lesser measure, contribute to the presence and viability of water-borne bacteria.) Manufacturing must stand near the top of, and very probably leads, any list of potential sources of water pollution. (See Table 3.3.)...
