Study on Biodegradation of Palm Oil-based UV-Curable Films in Soil

The palm oil-based ultraviolet (UV)-curable films were subjected to an outdoor soil burial test to investigate the biodegradation under natural environment. The films were burial in the soil experiment plot at the Nuclear Malaysia's Dengkil complex which is near the BTS building at block 42. Biodegradation tests are more specific to burial film in soil experiments for 12 months under natural conditions. The biodegradability of palm oil resin based UV-curable films were investigated and compared with the petrochemical resin based film. The films properties were compared with respect to properties of the film morphology and the film weight loss which are analyzed using the scanning electron microscope (SEM), an optical microscope and the weight loss of film calculation. These findings suggested that the palm oil-based UV-curable films show quite satisfactory biodegradation levels. (author)
