1. The Composition of Plastic Bottles

Plastic bottles are commonly made from polyethylene terephthalate (PET) or high-density polyethylene (HDPE). These materials, while durable and convenient, pose challenges in the decomposition process.

2. Factors Influencing Decomposition

Several factors impact the rate at which plastic bottles decompose. These include exposure to sunlight, temperature and the type of plastic. Understanding these factors is vital to comprehend the journey of plastic from consumption to decomposition.

3. Timeline of Plastic Bottle Decomposition

The decomposition timeline varies based on the conditions. Generally, it takes hundreds of years for plastic bottles to break down completely. The breakdown process involves photodegradation, where sunlight breaks the plastic into smaller particles over time.

4. Environmental Consequences

The extended decomposition period results in severe consequences for the environment. Plastic pollution poses a threat to marine life, wildlife and ecosystems. Microplastics (the remnants of decomposed plastic) infiltrate water sources affecting both aquatic and terrestrial ecosystems.

5. Sustainable Alternatives

To address the environmental impact of plastic bottles, embracing sustainable alternatives is imperative. Packaging made from materials such as glass, stainless steel and aluminium offer a greener option. However, these materials can be expensive and come with their own pitfalls, glass for example can be very energy intensive to manufacture.

Using the framework of reuse, reduce and recycle we came up with a hybrid solution. Our pouches contain 80% less plastic*, use up 9 times less carbon emissions* and come with a thin aluminium lining to prevent plastic impurity contamination. Not only that, they can be reused and recycled through our zero waste programme.

6. Conclusion

In conclusion, the decomposition of plastic bottles is a prolonged process with far-reaching environmental consequences. As consumers, we play a vital role in mitigating this impact by making informed choices and adopting sustainable alternatives.

By understanding the journey of plastic bottles from production to decomposition, we can make conscious decisions to reduce our environmental footprint. Together, we can contribute to a healthier planet for current and future generations.
