PET bottles: the ecological impact we can mitigate

Summary

This article analyses the life cycle and environmental impact of PET bottles, a ubiquitous material in the beverage industry. The three critical stages of their impact are explored: production, which requires huge amounts of oil; transport, which generates significant CO2 emissions; and disposal, which contributes to the global plastic pollution crisis and the spread of microplastics. It shows that a single bottle has a carbon footprint comparable to that of a car per kilometre. In the face of this “ecological bombshell”, the article presents DKR solutions, such as Water Houses and professional dispensers, not only as products, but also as a conscious choice to drastically reduce the consumption of single-use plastic and promote a responsible, zero-kilometre consumption model.

In 1973, American engineer Nathaniel Wyeth patented a material that would radically transform the packaging industry and consumption habits globally: PET (polyethylene terephthalate). Light, transparent, unbreakable and ideal for the packaging of carbonated drinks, it represented an innovative and promising solution. 

Today, billions of PET bottles are produced, marketed and consumed worldwide. However, behind an apparently simple and everyday gesture, such as buying a bottle of water, lies a worrying reality: we are contributing, often unknowingly, to a real environmental emergency.

According to the 2025 report of EA For Impact, It is estimated that about 31.9% of the plastic produced this year will be mishandled, ending up in unregulated landfills, open-air incinerators or dispersed directly into the natural environment. This translates into more than 72 million tonnes of plastic released into the air, water and soil by the end of the year.

The document also points out that, despite slight improvements in the management of plastic waste compared to previous years, overall production continues to increase, keeping the overall amount of poorly managed waste largely unchanged.

Protecting the environment and promoting more resource-conscious consumption are now top priorities. To effectively address this challenge, it is essential to understand the environmental impact hidden behind every single plastic bottle: a cost that goes far beyond the purchase price.

The life cycle of a bottle: an impact that starts long before waste

We are used to thinking about the problem of PET bottles only at the end of their very short useful life, when they become waste to be disposed of. In reality, their environmental impact is a journey in stages, each with a heavy ecological burden.

1. Production: a huge thirst for oil and energy

Each plastic bottle comes from oil, a non-renewable fossil resource whose extraction and refining are among the most polluting human activities. The worldwide production of PET bottles requires millions and millions of litres of crude oil each year, an energy-intensive process that releases large quantities of greenhouse gases into the atmosphere, contributing to climate change. We are, in effect, using a precious resource, formed over millions of years, to create a “disposable” object designed to be used for only a few minutes. The impact does not stop there: even the production process itself consumes huge amounts of water, making the idea of using water to produce a water container paradoxical.

2. Transport: the hidden carbon footprint by road

Once produced and filled, the bottles begin their long journey. Trucks travel hundreds, if not thousands, of kilometres to transport the water from the bottling source to distribution centres, then to supermarkets and finally to our homes. This logistical system generates colossal CO2 emissions. It is estimated that the carbon footprint of a single bottle of water, considering its entire life cycle, is comparable to that generated by a car travelling one kilometre. We are, in effect, transporting an asset (water) which, for the most part, we already have available on a zero-kilometre basis.

3. Disposal: the recycling myth and the ocean crisis

Even when we are diligent citizens and throw the bottle in the plastic container, the problem is far from solved. Recycling, while essential, is not a magic solution:

• Not everything is recycled: globally, only a small percentage of PET bottles are actually recycled. Many still end up in landfills, where they take hundreds of years to decompose, or worse, in the environment.
• Recycling requires energy: the process of collecting, sorting, cleaning and melting plastics consumes energy and produces emissions.
• Downcycling: Often recycled PET does not become a new bottle (bottle-to-bottle recycling), but is processed into lower quality products (fibres for textiles, padding), breaking the virtuous cycle.

The most dramatic consequence of this inefficient management is the pollution of ecosystems. It is estimated that the equivalent of a truck full of plastic waste is dumped into the sea every minute. Millions of tonnes of plastic, every year, invade the oceans, fragmenting into microplastics that enter the food chain, harming marine wildlife and ending up on our plates. The projections are alarming: according to António Guterres, Secretary General of the United Nations, speaking at the opening of the UN Conference on Oceans in Lisbon in June 2022, by 2050 the weight of plastic in the oceans could exceed the total weight of all fish.

DKR: the conscious choice for a future without single-use plastics

Faced with this scenario, resignation is not an option. The “tethered cap” (the non-removable cap for plastic bottles) is only the first phase of a wider transformation. The European Union's own directive (SUP Directive - Single-Use Plastic), which came into force in Italy on 14 January 2022, introduces a further requirement: from 1 January 2025, all packages with a capacity of up to 3 litres must contain at least 25% of recycled plastic. From 2030, this percentage must rise to 30%.

However, the solution already exists and is within reach: drastically reduce dependence on single-use PET bottles, rediscovering the value, safety and convenience of zero-mile water.

At DKR, our mission is to provide the tools necessary to make this transition simple, affordable and accessible to all. Our solutions represent real headmasters of sustainability, offering a concrete and tangible alternative:

• Water Houses: install a Water House in a municipality is a conscious choice that generates an immediate and measurable positive impact. By offering citizens the highest quality mains water (natural and sparkling, constantly monitored), action is taken on all three fronts:
  • The production of new plastic bottles is reduced, saving oil and energy.
  • Water transport by road is reduced to zero, reducing CO2 emissions.
  • It eases the burden on waste collection and disposal systems, helping to combat pollution.
• Dispensers for offices, schools and Horeca: also in work, school and catering contexts, the choice to install a dispenser connected to the water mains is a fundamental step. It means educating new generations in responsible consumption, offering employees and customers a high-quality service and communicating a concrete commitment to environmental sustainability. It is a gesture that improves the corporate image and promotes a culture of reuse and responsibility.

Liability and collective action

Pollution caused by PET bottles is a serious problem that requires a change in our habits. When we choose to fill our canteen from a Water House or a dispenser, we make a concrete choice: we do not feed an unsustainable system, we reduce waste in the sea and CO2 emissions.

The solution is simpler than it seems: safe and controlled tap water already arrives in our homes. With the right filtration technologies, we can make it our main choice, thus reducing dependence on PET bottles.
