If disposable nappies have only been around for 20 years or so?

by determining the decay rate of a sample of the specific components of any specific product under controlled, and uncontroled enviorments in sample time periods. which requires the testing by various terraneous or subterraneous conditions with a variety of humidities, dampness and oxygen levels to determine the decay rates for each condition. and the results are usualy interpeted as an average of the sample and the accelerant of the decay rate. so that you have enough time period samples to project an intrepeted epilog of decay prognosis interpolated, to predict the approximate time of complete decay of the complete sample. and in waste management you need to know what conditions are ideal for dealing with specific or general broad based waste products. and what possible dangers to the enviroment, they can produce as a side effect of decompositions. and since most products today, are not one specific compound, you need to know what decays first and last and what are the resultant byproducts of decompositions under various controled or uncontroled schemes.
