  • Energy required, air emission, and solid waste generation are calculated with available foreign data ad domestic status using Life Cycle Analysis in order to compare the environmental impact of beverage containers such as PET bottle, aluminum can, glass bottle, and paper pack. Glass bottles are found to be the worst acceptability when considering only recycling rate of glass cullet, however it becomme the best when the refill(reuse) rate of glass bottles is accounted into. To assess tile current and future environmental impact of beverage containers, energy required, air emission, solid waste generation of current data and recycling goals are compared. As a result of the study, recycling of each containers and the reuse of glass bottles must be increased by governmental enforcement to reduce the environmental impacts by beverage containers. Further study on this subject using detailed LCA(life cycle assessment) data should be implemented for the exact environmental and economic assessment.

  • Greenhouse gas (GHG) emissions are a major cause of global warming and climate change, and are currently emerging as serious environmental problems worldwide. Among them, glass bottles do not decompose naturally, and a lot of resources and energy are input into the production and processing processes, so recycling of glass bottles is important in terms of resource conservation, minimizing environmental pollution, and reducing GHG. Therefore, this study created a material flow diagram of glass bottles using related statistical data such as domestic glass bottle production and processing volume. In addition, the US EPA WARM model, Germany Prognos calculation method, and Denmark Christensen's calculation method were used to estimate the greenhouse gas reduction amount of glass bottles. As a result of the study, out of about 490,000 tons of waste glass bottles discharged as municipal waste, about 300,000 tons (61.2%) were recycled, and the rest were incinerated (22.1%) and landfilled (17.3%). As of 2022, it is estimated that approximately 73,399 tons CO2eq/yr will be reduced when applying the US EPA WARM model, approximately 52,847 tons CO2eq/yr when applying the Prgonos calculation method, and approximately 135,201 tons CO2eq/yr when applying the Christensen's calculation method. Further research is warranted that the methodology and GHG saving emission factors by reflecting glass recycling conditions and processes in Korea should be developed to reduce uncertainty of the results.
