Environmental Disposal

Spills should be cleaned immediately to prevent the spread of carbon black. If it is necessary to clean up a remote or small spill by dry sweeping, great care should be taken not to disperse the carbon black into the air.

Throughout the history of the development of fats and oils, many wet chemical methods have been developed to assess the quaUty of the raw materials and products. As sophisticated instmmentation develops, many of the wet methods are being replaced. Particular attention is being given to methods that eliminate the use of solvents which cause an environmental disposal problem. Many in-line sensors are also being developed to allow corrections of critical parameters to be made more quickly in the process. 

Nickel-metal hydride is a popular alternative to Nicad batteries since they are capable of operating 75 percent longer after each charge, are less likely to suffer memoiy effects, and pose less of an environmental disposal problem. The difference between nickel-metal and Nicad batteries is that the negative... 

The other choice is to use environmentally friendly disposable diapers like Tushies. They re a cotton-blend diaper made with chlorine-free wood pulp that contains no chemicals or gels. (Some other brands of environmental disposables do use gel if you read the fine print.) Tushies can be found at Whole Foods,... 

A new vanadium pentoxide battery produces more electrical energy per pound than the lead storage batteries in cars today. They are also likely to cause fewer environmental disposal problems. 

Since the beginning of time, polysaccharides have been of immense importance to human civilization. They are a vital component of our food as an energy source (e.g. starch), and also as roughage (e.g. cellulose fibers) which aids in digestion. They are the earliest known structural materials, i.e. in the form of wood (which is chiefly cellulose, a polysaccharide), that still hold a prominent place as an engineering material. The role of polysaccharides in human civiUzation is vast, and they surround us all the time, even in this era of synthetic materials/plastics in the form of textiles, paper, glue, food and food additives, etc., without causing any major environmental disposal problems (unlike their synthetic counterparts).
