Studies have shown that high-circulation glass bottles reduce carbon dioxide emissions

High-circulation glass and plastic bottles can reduce greenhouse gas emissions, according to a study. A recent study by The Waste Resources Federation (WRAP) has been hailed by UK glass companies as removing the stigma that glass production releases large amounts of carbon dioxide. The researchers examined the production and transportation of glass bottles and found that lightweight glass bottles with high recycling rates produced the same amount of greenhouse gases as lightweight PET bottles. Although the amount of CO2 released in the production process of PET bottle is high, the amount of gas released in the transportation process is low. Rebecca Cockin, Recycling Manager at UK Glass, said: "We are encouraged by the findings of the report, which helps to dispel some of the criticisms and negative impacts on the glass packaging industry and to promote the development of the glass packaging industry." Sir Richard Swannell, chairman of WRAP, said: "This demonstrates that the recycling rate of lightweight glass bottles is an environmental positive." In this study, 75Cl glass bottles and PET bottles were compared. Bottle types include 45g PET non-circulating bottles, typical 496g glass bottles with 81% cycle rate, and 365g light glass bottles with 81% cycle rate. The study also included glass bottles with 365g cycle rates of 92% and PET bottles with the same mass cycle rates of 50% and 100%. The study found that the 54G PET bottle was in the 365g glass bottle release range.
