Understanding Recycled Polyester

Before diving into whether recycled polyester is better for the environment, let’s understand what it is. Recycled polyester, often known as rPET, is made by melting down existing plastic and re-spinning it into new polyester fiber. This plastic often comes from clear plastic water bottles, or sometimes even from other polyester fabrics.

The Environmental Benefits

1. Reduces Waste: One of the most significant benefits of recycled polyester is its role in reducing waste, particularly plastic waste. By repurposing plastic bottles that might otherwise end up in landfills or the ocean, rPET gives a second life to materials that are notoriously hard to decompose.

2. Saves Energy and Water: The process of recycling polyester uses less energy and water compared to producing virgin polyester. It’s estimated that manufacturing rPET generates about 75% less CO₂ emissions than virgin polyester.

3. No Petroleum Required: Virgin polyester is made from petroleum, a non-renewable resource. Recycled polyester, on the other hand, bypasses this requirement, reducing our dependence on oil.

4. Less Pollution: The process of making virgin polyester is not only energy-intensive but also polluting, with various chemicals and dyes involved. Recycled polyester often requires fewer processes, thereby reducing pollution.

The Other Side of the Coin

However, it’s important to also consider some drawbacks:

1. Quality and Longevity: Sometimes, the quality of recycled polyester can be lower than virgin polyester. This can affect the longevity of products, potentially leading to a faster cycle of disposal and purchase.

2. Chemical Recycling Process: The process of breaking down plastics into fibers can involve chemicals, though advancements are being made to make this process more eco-friendly.

3. Microplastic Shedding: Like all synthetic fibers, recycled polyester can shed microplastics when washed. These tiny particles can end up in waterways and oceans, contributing to pollution.

So, Is It Really Better?

Despite the drawbacks, the answer leans towards a ‘yes’. Recycled polyester is a step in the right direction towards a more sustainable and environmentally conscious world. It helps to tackle the problem of plastic waste, reduces dependency on new petroleum-based products, and generally has a lower environmental impact than virgin polyester.

Ultimately, recycled polyester is part of a larger conversation about sustainable practices in manufacturing and consumption. It’s not the silver bullet to all environmental issues, but it is a viable, more sustainable option that can be part of a broader strategy to reduce our environmental footprint.


Recycled polyester offers a more sustainable alternative to virgin polyester, with significant benefits like reducing waste, conserving resources, and decreasing pollution. However, it’s important to continue improving the ways we produce and use materials, striving for even more environmentally-friendly solutions.
