Biodegrading Material (IMAGE) University of California - San Diego Caption Biodegradation of PU cubes over 12 weeks. Degradation was analyzed through A) Change in appearance, B) Cube mass and C) Maximum force at 50% compression force deflection (CFD). Error bars indicate sample standard deviations of the triplicate measurements. For compost and soil mass loss, p<0.01 and for compost and soil CFD, p<0.01 (Table 2 in published paper).
