Paper looking at improving the test methodology for compost stability

A paper by Dr Thomas Aspray of Heriot Watt University (and others) outlines how the methodology of the stability test ORG20 can be modified to give more precise results. 

The ORG0020 dynamic respiration test is effective at distinguishing source segregated organic waste derived composts across a wide range of stabilities when compared to other standard tests; however, using the original setup, the test is affected by variability in flow rate with time and across sample replicate vessels. This paper modified the set up and provides evidence of greater precision of the modified setup compared to the original.
