Abstract: | Biodegradation of plastic films based on polyvinyl alcohol and protein hydrolysate under aerobic condition was assessed by means of respirometric test (bod measurements) and/or Zahn-Wellens test. The tests were provided in water envirofnment after inoculation by activated sludge drawn-up from waste water treatment plant. 13 mixed film blends were tested it was found that biodegradation of these blends was practicaly non-independečntable on their compoisiton. |
