An industry producing billions of pairs of shoes a year around the world is being picked over its environmental footprint. Typical manufacturing of shoes produces a lot of pollution, waste, and resource depletion, from sourcing the raw material through manufacturing processes to end-of-life disposal. In this complex ecosystem, the humble thread goes unnoticed but plays a vital role. Eco-friendly stitching and environmentally friendly threads offer an excellent opportunity to reduce the environmental input of shoe production and pave the way to a green industry.
The Environmental Impact of Conventional Threads:
Some of the traditional fossil fuel-based threads are polyester and nylon. Energy and greenhouse gas intensive production is involved in their production, causing climate change. These synthetic fibers are also non-biodegradable and will, in a landfill, potentially release microplastics into the environment once biodegradable fibers are removed. These threads are often dyed in fairly hazardous chemicals that are polluting waterways and destroying ecosystems.
Natural fiber cotton is frequently offered as a less sustainable alternative. Although conventional cotton farming is a resource intensive enterprise consuming large quantities of water, fertilizers and pesticides. It deteriorates soil, pollutes water, and causes the dwindling of biodiversity. Yet, organic cotton only helps to an extent, and its use is still not universal because of the higher costs and lower yields.
The Need for Sustainable Thread Alternatives:
A change is necessary towards the shoe industry becoming more sustainable as a means to greatly decrease how environmentally damaging it is. They should also have certain key characteristics in these alternatives.
- Biodegradable and Renewable: Natural, renewable, and can decompose naturally, reducing waste and pollution.
- Low Environmental Impact Production: Manufactured out of processes that require minimal energy, water, and chemical consumption.
- High Performance: Able to do the required job of shoe manufacturing, long lasting and a quality product.
- Ethical Sourcing: Purchased from sources that uphold workers’ rights and foster fair labor practices.
Exploring Sustainable Thread Options:
There are a number of emerging promising sustainable thread alternatives suitable for the shoe industry.
- Recycled Polyester Sewing Thread (rPET):
- The production of rPET is obtained from post-consumer waste such as plastic bottles.
- It also helps decrease virgin polyester demand and cut down on plastic waste going to landfills and the seas.
- Producing this requires less energy than virgin polyester, therefore emitting less greenhouse gas. However, microplastic shedding continues to be of concern.
- rPET is a good alternative material for lots of parts within a shoe and can be coloured in a myriad of ways to create polyester embroidery thread.
2. Organic Cotton:
- Dropped for synthetic pesticides and fertilizers and grown without impacting the environment.

- Lyocell is a very strong and durable thread and feels good.
4. Linen:
- Flax fibers are made from naturally sustainable crops, low water, and pesticides.
- Strong, durable, and naturally biodegradable.
- It has a low environmental impact from design through the lifecycle.
- Linen has an appearance and a feeling all its own and is a very tough fabric.
5. Bamboo:
- This is a fast-growing and renewable resource that also has low water and pesticide requirements.
- Naturally antibacterial and breathable.
- Biodegradable and compostable.
- However, processing bamboo into fibers involves chemicals.
- Bamboo is also naturally antimicrobial and is a strong and durable thread.
6. Piñatex:
- Made from pineapple leaf fiber, a product of pineapple harvesting.
- It reduces the waste and provides them with an extra income stream from their production.
- Biodegradable and compostable.
- Offers a leather-like texture and appearance.
- Pinatex is a very original material, from the whole shoe or just the stitching.
7. Mylo (Mushroom Leather):
- Produced from mycelium, the root structure of mushrooms.
- Mimicking one’s origins in a controlled environment.
- Biodegradable and compostable.
- Offers a leather-like texture and appearance.
- The other very innovative material in this case is Mylo, which is very sustainable.
8. Bio-based Polyamides:
- Made of renewable resources such as castor beans or corn.
- Have similar performance characteristics as conventional polyamides.
- Reduce reliance on fossil fuels.
- Biodegradability is being continually improved.
- Traditional nylon is good for its place out of traditional choices, however, bio-based polyamides are a good alternative.
Challenges and Opportunities:
However, several obstacles prevent the spread of such sustainable thread alternatives since now it’s available in growing numbers.
- Barrier to entry: Sustainable threads tend to come at a higher price than conventional threads, which will be a barrier for price-sensitive manufacturers.
- Scalability: Part of the reason that some sustainable threads are not widely available is due to the fact that it is difficult to produce the threads at a large scale in order to provide them for the large-scale mass manufacturing of shoes.
- Performance and Durability: High-performance sustainable threads are needed in order to meet the durability requirements of various shoe types and applications.
- Consumer Awareness: The first step is educating the consumers about the benefits of sustainable threads and moving towards eco-friendly shoes.
- Traceability and Transparency: This verifiability begins right from the supply chain, where the manufacturers of the thread need to ensure that they are ensuring traceability and transparency throughout their supply chain.
To these challenges, however, there are also several opportunities for innovation and collaboration.
