According to research reports, high-cycle glass and plastic bottles reduce the release of greenhouse gases.
Recently, research conducted by the Waste Resource Coalition (WRAP) has been highly praised by the British Glass Corporation because it will eliminate the prejudice that people are able to release large amounts of carbon dioxide for glass production.
Researchers inspected the production and transportation of glass bottles and found that high recycled glass bottles produce as much greenhouse gas as light PET bottles. Although more CO2 is released during the PET bottle production process, the amount of gas released during transport is less.
Mr. Rebecca Cockin, Recycling Manager of British Glass Company, pointed out that “we are very encouraged to report the results of the research. The report helps us to expel some of the criticism and negative impact on the glass packaging industry and promote the development of the glass packaging industry.â€
WRAP Chairman Richard Swannell said, "This proves that the recycling rate of lightweight glass bottles is a positive factor for the environment."
This study compares 75cl glass bottles with PET bottles. Bottle types include 45g PET non-recycle bottles, typical 496g glass bottles with 81% recycle rate and 365g lightweight glass bottles with 81% recycle rate.
At the same time, the study also included 365g glass bottles with a cycle rate of 92% and PET bottles with the same mass cycle rates of 50% and 100%. The study found that the gas release of the 54g PET bottle was within the 365g glass bottle release range.
