The Pharmaceutical Packaging Plastics Survey conducted by the Franklin Union compared the total energy consumption, solid waste and greenhouse gas emissions per 100,000 ounces of soft drinks in 20-ounce PET bottles, 8-ounce glass bottles or 12-ounce aluminum cans. According to the survey, the results show that PET bottles emit less greenhouse gases, waste and energy consumption throughout their life cycle. When comparing the energy consumption, emissions, and solid waste of 10,000 equally sized 12-ounce containers, the overall energy consumption is similar. However, the greenhouse gas emissions of PET medical packaging plastic bottles are only 2/3 of the aluminum can emissions, which is about half of the glass bottle emissions.
When comparing a 12-ounce PET bottle to a 12-ounce aluminum can or a 12-ounce glass bottle, the former produces less solid waste. However, from the volume point of view, the volume of solid waste produced by the aluminum can is 16.5 cubic yards, the PET plastic bottle is 29.9 cubic yards, and the glass bottle is 37.3-44.1 cubic yards.
The survey compared 100,000 ounces of soft drinks in 20-ounce PET bottles, 8-ounce glass bottles, and 12-ounce aluminum cans. PET bottles emit 59% less greenhouse gas than aluminum cans over their life cycle. 77% less. The total energy consumption of PET plastic bottles is 11 million BTU per 100,000 ounces of soft drinks, 16 million BTUs for aluminum cans and 26.6 million BTUs for glass bottles.
