The paper explores how biodegradable packaging materials influence microbial respiration in activated sewage sludge. Experiments were conducted to measure biological oxygen demand (BOD) and anaerobic biodegradation, evaluating the biodegradability and methane production potential of different bioplastic samples. These bioplastics often contain metal additives like silver, zinc, and titanium, which are incorporated to enhance antimicrobial properties, durability, and functionality. The presence of these metals can influence the degradation behavior of the materials, affecting both aerobic and anaerobic processes.
