Impact of the plastic bottle production on the natural environment. Part 2. Analysis of data uncertainty in the assessment of the life cycle of plastic beverage bottles using the Monte Carlo technique
Processes for prodn. of poly(ethylene terephthalate) (PET) and polylactide (PLA) bottles were compared according to environmental life cycle assessment rules to det. the level of reliability of the rules. The Monte Carlo anal. was used. The possibility of practical use of log-normal probability distributions in eco life cycle assessment under conditions of uncertainty was demonstrated. The probability distributions were based on collected industrial data. The prodn. of PLA bottles had higher negative impact on the environment and human health than the process for prodn. of PET bottles.
