plastic bottles made of PET (Polyethylene Terephthalate) are everywhere. In this article, we take an in-depth look at the rise of PET bottles and their impact.
The plastic bottle industry has seen tremendous growth over the past few decades. PET plastic bottles in particular have become extremely popular for packaging beverages like water and soda. Some key facts about the rise of PET bottles
- PET was first used for soft drink bottling in the 1970s and its use has increased steadily since then. It has now almost completely replaced glass bottles.
- In the US alone, over 50 billion PET bottles are sold annually. Worldwide bottle consumption is estimated to be over 1 trillion bottles per year.
- The popularity of single-use PET water bottles has grown dramatically with the trend of increased consumption of bottled water instead of tap water. Per capita bottled water consumption in the US has risen over 13-fold since 1976.
- Developing countries are seeing the fastest growth in PET bottle usage as lifestyles become more westernized and incomes rise. Bottled beverage consumption in China, for example, has increased by over 15% annually in recent years.
So in summary, inexpensive PET plastic has enabled incredible volumes of pre-packaged beverages to be distributed worldwide, transforming drinking habits globally. Let's look deeper into what makes PET such an ideal packaging material.
The Properties of PET That Make it Ideal for Bottles
PET plastic has a unique blend of properties that explain its dominance in the bottle market:
- Lightweight and durable - PET is roughly 25% lighter than glass but just as shatter-resistant, making it ideal for transportation and storage. This also reduces environmental impacts from reduced transportation fuel usage.
- Optically clear - PET allows the contents inside to be visible, a key factor for beverage branding and marketing. This "shelf appeal" gives it an advantage over opaque plastics.
- Gas and moisture barrier properties - PET forms an effective barrier to air and moisture, protecting product quality and freshness during storage and distribution.
- Recyclable - PET is one of the most recyclable plastics and has recycling codes allowing it to be processed separately from other plastics. Over 28% of PET bottles consumed in the US are currently recycled.
- Molding versatility - PET lends itself to a variety of forming and thermoforming manufacturing processes to create bottles of diverse shapes optimised for different beverage types.
- Food contact approval - PET Bottles is considered inert and does not leach harmful chemicals into beverages, having received approvals from food regulatory bodies worldwide.
No other plastic combines all these functional properties better than PET, making it the natural choice for the booming bottled beverage industry. However, its increasing usage also comes with environmental consequences that need addressing.
The Environmental Impacts of PET Bottles
While PET bottle usage delivers certain efficiencies, it has also contributed to growing environmental concerns around plastic waste:
- Plastic pollution - Only a fraction of PET bottles are recycled, with most ending up as litter or in landfills. It can take hundreds of years for PET bottles to decompose.
- Greenhouse gas emissions - The production and transportation of billions of single-use PET bottles contributes significantly to carbon emissions worldwide. Their lightweight benefits are offset by the sheer volume produced.
- Resource depletion - Oil is the primary feedstock for PET production and bottled beverages consume growing amounts of fossil fuels for production, filling, transport and disposal.
- Microplastic contamination - As PET bottles break down from sun and wave action, they shed microplastics polluting oceans, waterways and entering the food chain. Over 80% of tap water samples globally now contain microplastics.
Addressing these environmental issues will require a collaborative effort across the value chain - from manufacturers investing in recycled content and new technologies, to governments incentivizing recycling infrastructure and consumer behavioral change. Some solutions being implemented include standardized recycled content mandates, bottle deposit programs and shifting to reuse models.
The Future of PET Bottles - Can Sustainability Be Achieved?
As concerns around single-use plastics grow, the PET bottle industry is exploring more sustainable solutions through recycling, reuse and new delivery formats:
- Increased recycled content - Recycling rates will need to increase dramatically to meet proposed recycled content mandates of 50% or higher for plastic bottles. Industry is investing in recycling technologies.
- Reusable formats - Reusable glass or durable plastic bottles are being promoted for bottled water and beverages consumed at home or office. Companies like S'well and Klean Kanteen offer premium reusable options.
- Returnable/refillable models - More "bottle deposit" recycling programs and infrastructure are enabling bottles to be returned, cleaned and refilled hundreds of times rather reducing overall bottle usage. Terracycle partnership with Loop is piloting this.
- Alternative delivery formats - Growth in larger reusable multi-pack containers or bag-in-box formats is reducing individual bottle waste generation, though single-serve bottles still dominate on-the-go consumption.
- Bioplastics and biodegradability - Research into plant-based PET alternatives or additives enabling faster biodegradation in natural environments are intensifying but commercial scalability challenges remain.
With innovation focused on the circular economy principles of reduce-reuse-recycle, the PET bottle systems of tomorrow can potentially achieve sustainability while still meeting consumer convenience needs. Success will depend on coordinated collective action across the plastic value chain and among policymakers. With an estimated $140 billion global industry at stake, there is ample incentive for all parties to work towards more environmentally responsible solutions.
