Our Commitment to Sustainable Manufacturing
"We haven't inherited resources from our ancestors, but have borrowed them from our children."
Sustainability requires seeing the world as an integrated system — one that connects business, society, and the environment rather than treating them as separate concerns. Our mission is to manufacture responsibly: through processes engineered to minimize negative environmental impact, conserve energy and natural resources, and remain genuinely economically sound at the same time. Below is exactly how that commitment plays out across our facility — not as a claim, but as a set of measurable practices.

Water Conservation & Zero Liquid Discharge
Water conservation is the need of the hour, and we do our part by continually enhancing our production processes to limit water use at every stage.
We've constructed a rainwater harvesting tank with capacity for up to 8 crore litres of water. Our manufacturing setup also runs a Zero Liquid Discharge (ZLD) unit that recycles and purifies wastewater, leaving negligible discharge at the end of the treatment process. That unit is backed by a dedicated wastewater treatment plant that recycles up to 98% of effluent — significantly limiting our net consumption of fresh water across production.
Energy Conservation in Textile Manufacturing
The need for energy conservation has taken on real urgency in the textile industry — rising energy costs on one side, real supply shortages on the other.
As a leading vertically integrated textile manufacturer, Premo Denim continually works on energy conservation through improved operational and maintenance practices across every unit, in line with our broader commitment to conserving natural resources.
In practice, that's meant replacing illuminating devices with energy-efficient alternatives, ensuring optimal utilization of equipment across our facility, and maintaining full suction pressure through our OHTC dust collection system across the ring frame, speed frame, link coner, and TFO machine areas in our spinning plants — reducing energy waste at the equipment level, not just on paper.
Recycled Waste Materials: PET-to-Yarn Manufacturing
Considering the larger picture of a sustainable environment, waste management has never mattered more than it does today.
One of the ways textile manufacturing is helping reduce pollution is by producing clothing and fabric from waste materials like PET (polyethylene terephthalate) — the same plastic behind much of the world's bottle and packaging waste.
The process begins by melting plastic waste into pellets, then forming chips, which are spun into threads and smaller fibre yarns. Those fibres are stapled together with different fibre varieties as required, producing full-length recycled yarn ready for fabric production.
Beyond reducing plastic pollution directly, this recycling process reduces landfill volume, lowers dependence on virgin fibre production, cuts pollution emissions associated with raw fibre processing, and reduces the use of harmful chemicals and dyes across the broader production chain.
Recycled PET is one part of a broader sustainable yarn program — see our full guide to 7 sustainable yarns below, and explore finished fabric on our Denim Fabric page.
7 Sustainable Yarns We Use in Denim & Fabric Manufacturing
Every fabric Premo Denim produces starts as a yarn decision. Alongside conventional cotton, we work with seven sustainable and specialty yarns — each suited to a different combination of feel, performance and environmental footprint. Here's what each one actually does, so you can specify the right one for your collection.
Quick Comparison
| Yarn | Made From | Best For |
| Hemp Yarn | Cannabis sativa stalk fibre | Durability, shape retention, UV resistance |
| Recycled Polyester (rPET) | Post-consumer plastic bottles | Lower carbon footprint, infinitely recyclable blends |
| Recycled Cotton | Reclaimed cotton fabric waste | Lower water use, circular collections |
| EcoVero | Certified sustainable wood pulp | Soft hand-feel, EU Ecolabel-certified sourcing |
| Bamboo Yarn | Inner bamboo stem fibre | Softness, odour resistance, breathability |
| Banana Yarn | Banana tree bark fibre | Fine, spinnable natural fibre alternative |
| Coffee Charcoal | Spent coffee grounds | Moisture-wicking, odour control performance wear |
1. Hemp Yarn
Hemp yarn is made from the outer stalk fibres of the cannabis sativa plant. It's one of the strongest and most durable natural fibres available, generally outlasting cotton over repeated wear and washing.
- Made from the outer portion of cannabis sativa plant stalks
- Among the strongest natural fibres, with a longer usable life than most alternatives
- Low stretch, so garments hold their shape well over time
- Better colour retention than cotton
- Naturally porous, breathable, and quick-drying
- Thermoregulatory, UV-resistant, antimicrobial and washable
- Holds up consistently even under prolonged sun exposure
2. Recycled Polyester Yarn (rPET)
Recycled polyester yarn is made from post-consumer plastic bottles. At Premo Denim, the plastic is melted into pellets, formed into chips, and spun into threads and fibre yarn, which can then be stapled with other fibre types as an order requires — the same recycling process behind our plant-level sustainability practices.
- Made from recycled PET (polyethylene terephthalate) plastic bottles
- Durable and eco-friendly compared to virgin polyester production
- Significantly reduces carbon footprint versus virgin polyester manufacturing
- Can be recycled indefinitely without losing usability
- Diverts plastic waste from landfill into usable fibre
3. Recycled Cotton Yarn
Recycled cotton yarn — also known as reclaimed cotton, regenerated cotton, or shoddy — is made by converting existing cotton fabric back into reusable fibre for new textile production.
- Converts cotton fabric waste into fibre that can be respun and reused
- Also referred to as reclaimed cotton, regenerated cotton, or shoddy
- Requires less water than growing virgin cotton, reducing both water and energy consumption
4. EcoVero Yarn
EcoVero is a viscose-based yarn made from certified, sustainably sourced wood pulp, produced under the EU Ecolabel's strict environmental standards.
- Made from certified and controlled, sustainably sourced wood and pulp
- Lower emissions and water impact compared to conventional viscose
- Certified under the EU Ecolabel for strict production methods
- Cuts CO2 emissions and fossil fuel consumption by up to 50%
- Up to 50% lower water impact than conventional viscose
- Biodegradable, soft, and comfortable against the skin
5. Bamboo Yarn
Bamboo yarn is derived from the inner stem of the bamboo plant, producing a fibre that's noticeably softer than cotton with useful built-in performance properties.
- Made from the inner bamboo stem; softer to the touch than cotton
- Naturally antimicrobial and resistant to odour buildup
- One of the most eco-friendly and thermoregulatory fibres available
- Has natural skin-soothing properties and helps protect against UV exposure
- Low risk of skin allergies
- Breathable and moisture-resistant
6. Banana Yarn
Banana yarn is a biodegradable natural fibre derived from the bark of the banana tree — a byproduct fibre that performs surprisingly well against more familiar alternatives.
- Biodegradable natural fibre derived from banana tree bark
- Made of thick-walled tissue, naturally bound together by plant gums
- Composed of cellulose, hemicellulose and lignin
- Visually similar in appearance to bamboo fibre
- Often outperforms bamboo and other natural fibres in fineness and spinnability
7. Coffee Charcoal Yarn
Coffee charcoal yarn is made from spent coffee grounds (SCG) — the residual byproduct left behind by the world's most consumed beverage.
- Made from spent coffee grounds, a waste byproduct of coffee production
- An estimated 33 million pounds of spent coffee grounds are discarded globally every single day
- Efficiently wicks moisture from skin to fabric and absorbs sweat quickly
- Helps control body odour throughout the day, making it well suited to performance and activewear-adjacent denim
