Abstract
LCA of manufacturing processes and waste treatments of packages for drink is studied using published data. PET bottles, tin steel cans, aluminum cans, glass bottles and carton are selected as packages for drink. The waste treatments of landfill, incineration with and without electric power generation, “package to others” recycle and “package to package” recycle are compared.
The inventory results are the following: Incineration of PET bottle is better than material recycle in reducing solid waste. In future, the use of PET bottles by raw material of in steel making will be the best option. Recycle of steel and aluminum cans are better than landfill. Ninety five percent of CO2 emission of collection and transportation of waste is from collection process. The CO2 emission of one-way-use glass bottle is much higher. Glass bottle should be used repetitively. The CO2 emission of carton was very little as compared with other package for drink because it is made from biomass. Recycle from carton to toilet tissue was the best option.
