PET is a cost-effective and environmentally friendly packaging option. A recent Life Cycle Analysis (LCA) conducted by the Allied Development Corporation determined how the environmental footprint and greenhouse gas emissions of manufacturing and transporting PET relates to alternative forms of packaging. The first study found that in North America, PET is the most favorable alternative when compared to aluminum cans and glass bottles for a 355 ml carbonated soft drink application. When measuring greenhouse gas emissions and energy consumption, PET containers had the best performance.
The following LCA studies relating to PET are available for viewing:
- CSD Beverage Package Performance in North America
- CSD Beverage Package Performance in Europe
- Wine Package Performance in North America
Bottlers have been consistently reducing the amount of material that goes into manufacturing beverage containers. Half-liter plastic water bottles now use as little as 12 grams of PET, nearly 40% less than the average amount just a few years ago. Likewise, soft drink bottles, though heavier to keep in carbonation, are becoming increasingly lighter. These lightweight PET bottles require fewer raw materials to produce, less fuel for transport and are still completely recyclable. We encourage the development of new technologies to decrease the environmental impact of PET containers, increase recycling services and improve consumer recycling habits of PET and other recyclable products.
Husky Injection Molding Systems (www.husky.ca) recently announced the development of new manufacturing equipment that helps increase the amount of recycled material in PET bottles, helping to make them even more sustainable.
