Life-Cycle Environmental Impact Assessment of Primary Beverage Containers: Glass versus Plastic Bottles
AI summary Read the abstract
This study compared the full life-cycle environmental impacts of glass versus polyethylene terephthalate (PET) plastic beverage bottles using Leopold Matrix analysis. Both container types generated significant negative environmental impacts across abiotic, biotic, and anthropic components, with glass scoring -712 and plastic -690, indicating comparable harm to ecosystems and human health.
Pollution originating from the life cycle of packaging is increasing and can have potentially irreversible consequences for the environment.In the beverage industry, the most common materials used for the production of primary packaging are glass and plastic.The objective of this study was to compare the environmental impacts of polyethylene terephthalate and glass bottles.The Leopold Matrix was applied to evaluate the environmental impact of the life cycle of both bottles, using information from a wide range of scientific articles and peer-reviewed indexed journals.The evaluation took into account the abiotic, biotic, and anthropic components generating negative consequences for ecosystems, human health, and fauna and flora.The study found that both containers generate negative environmental impacts throughout their life cycle.This was evidenced in the results of the matrix, where the total values symbolize -712 and -690 for glass and plastic, respectively.

AI summary Read the abstract
This life cycle assessment of beverage packaging compared glass, aluminum, PET, HDPE, milk cartons, and Tetra Pak containers across three drink categories, finding that 100% recycled aluminum cans, Tetra Pak, and milk cartons were less environmentally impactful than plastic bottles in their respective categories.
Life cycle assessment of single-use and reusable plastic bottles in the city of Johannesburg
AI summary Read the abstract
A life cycle assessment compared the environmental impact of single-use and reusable PET plastic water bottles in Johannesburg, South Africa. Reusable bottles had a lower overall environmental impact when used multiple times, but manufacturing and end-of-life disposal still carry significant costs. The study provides guidance for improving plastic bottle policies in South Africa.
