According to research reports, high-recycle glass and plastic wine bottles can reduce the release of greenhouse gases. Recently, the research conducted by the Waste Resources Association (WRAP) has been well received by British glass companies because it will eliminate the prejudice that glass production can release a large amount of carbon dioxide. Researchers inspected the production and transportation process of glass bottles and found that light glass bottles with high circulation rate produced as much greenhouse gas as light PET bottles. Although the amount of CO2 released during the production of PET bottles is relatively large, the amount of gas released during transportation is relatively small. Mr. Rebecca Cockin, Manager of Recycling Department of British Glass Company, pointed out, "We are very encouraged by the report's research results. The report will help us expel some criticisms and negative influences on the glass packaging industry and promote the development of the glass packaging industry." WRAP Chairman Richard Swannell said, "This proves that the recycling rate of lightweight glass bottles is a positive factor for the environment." This study compared 75cl glass bottles and PET bottles. Bottle types include 45g PET non-recycling bottles, typical 496g glass bottles with a circulation rate of 81% and 365g lightweight glass bottles with a circulation rate of 81%. At the same time, the study also included 365g glass bottles with a 92% circulation rate and PET bottles with the same mass circulation rate of 50% and 100%. The study found that the gas release of 54g PET bottles was within the release range of 365g glass bottles.
