Organic Cotton vs Recycled Polyester
The key difference between Organic Cotton and Recycled Polyester is the source material and end-of-life: organic cotton is a biodegradable natural fibre grown without synthetic pesticides (GOTS-certified), while recycled polyester (rPET) is a synthetic fibre made from post-consumer plastic bottles that diverts waste from landfill but sheds microplastics.
Head-to-Head
Organic Cotton Jersey
Strengths
- Biodegradable at end-of-life — breaks down in 1–5 months in composting conditions
- GOTS certification provides full supply-chain transparency from farm to garment
- Superior hand-feel and breathability — customers consistently prefer the touch
- No microplastic shedding during washing, unlike any synthetic
- Strong storytelling value — consumers understand and trust 'organic cotton'
Best For
Recycled Polyester
Strengths
- Diverts plastic bottles from landfill — 1 kg of rPET uses approximately 27 PET bottles
- Excellent moisture-wicking and quick-dry performance for activewear
- Higher colour fastness and UV resistance than cotton — colours stay vibrant longer
- Lower water consumption in production — uses 90% less water than virgin polyester
- GRS certification (Global Recycled Standard) validates recycled content claims

Verdict
Our Recommendation
Choose Organic Cotton for basics, t-shirts, and any garment where touch, breathability, and biodegradability matter most. Choose Recycled Polyester for activewear, outerwear, and performance pieces where moisture-wicking and durability are priorities. Many brands blend both (e.g., 60/40 organic cotton/rPET) to get the best of each.
Common Questions
Frequently Asked
Is organic cotton more sustainable than recycled polyester?
Neither is universally 'more sustainable' — they solve different problems. Organic cotton eliminates pesticides and biodegrades, but uses more water. Recycled polyester diverts plastic waste and uses less water, but sheds microplastics and never biodegrades. The best choice depends on your brand's sustainability priorities.
Can you blend organic cotton with recycled polyester?
Yes, and it's increasingly popular. A 60% organic cotton / 40% recycled polyester blend combines the softness and breathability of cotton with the durability and moisture management of rPET. Note that blended fabrics are harder to recycle at end-of-life.
Which fabric is better for screen printing?
Organic cotton jersey provides a better printing surface for screen printing and DTG, with sharper detail and more vibrant colours. Recycled polyester requires sublimation or specialised inks for best results, as standard water-based inks don't bond well to synthetic fibres.
