The cumulative biodegradation rates (in %) for the two concentrations of test material at 3, 5, 7, 10, 14, 17, 20, 24, 28 and 29 days were 1.0 and 1.0, 2.1 and 2.4, 4.5 and 4.57, 4.98 and 5.83, 8.28 and 10.4, 13.3 and 15.4, 16.3 and 18.1, 17.4 and 21.8, 21.7 and 27.6 and 23.2 and 28.5, respectively. At the same time intervals, values (in %) for inoculum controls were 12.9 and 12.7, 15.1 and 15.4, 17.2 and 14.4, 22.0 and 22.7, 25.6 and 23.5, 20.7 and 21.2, 24.4 and 23.4, 25.5 and 24.5, 23.3 and 23.4 and 20.1 and 19.6, respectively.

Since a >= 60% biodegradation rate was not achieved within 28 days, the material was not deemed readily biodegradable. The material was considered inherently biodegradable.
