Samples that made up groups II and III still clustered into the upper left. The early samples from the full-scale composting of nitrogen amended or unamended MSW (F/MSW0/ and +) fell into the same region as early samples of material composted at the pilot-scale facility.
When this amended or unamended MSW was composted at the full-scale and cured at the pilot-scale, it clustered with
the other older materials sampled.
