ZERØTEC, a London-based start-up, is helping put the UK and in fact the world at the heart of fashion’s sustainability shift by tackling one of the industry’s most overlooked sources of waste, the material lost before garments ever reach the shop floor.
Brands are under growing pressure to balance innovation with environmental responsibility and through advanced digital pattern design and smarter pre-production processes, ZERØTEC and a small number of other innovators are helping fashion businesses reduce waste at the source, while opening up a wider conversation about why the earliest stages of garment creation matter more than many people realise.
No matter which industry you look at, demand has changed and consumers no longer simply want great products at a great price, they want them quickly, conveniently and with as little friction as possible. The fashion industry is no exception, but in a world of accelerated production cycles, fast-changing trends and rising expectations, it is often the environment that pays the price.
Founder of ZERØTEC Nick Betts says: “While many conversations around fashion waste focus on what happens after clothing has been bought, worn or discarded, one of the biggest issues begins much earlier. Long before a finished piece reaches a rail, warehouse, shop floor or online checkout, waste can already have been created at the design and pre-production stage.”
What is pre-production fashion waste?
Waste exists in every industry. In construction, excess materials are routinely discarded in industrial bins, while in the food and beverage sector, unused ingredients and spoilage can quickly add up.
In fashion, one of the biggest sources of waste is excess material, particularly fabric.
At the design stage, material waste often begins with pattern creation. Traditional pattern-making involves laying out garment shapes on fabric, but this process can leave unused gaps, which become offcuts that are often too small or awkwardly shaped to be repurposed. When multiple rounds of sampling and prototyping are added into the mix, the problem grows even further. Designers create test garments, revise fits and adjust styles, frequently discarding fabric along the way.
In fact, this type of waste is estimated to reach around 60 billion square metres each year, which is enough fabric to cover Austria, or roughly one million football fields.
Nick adds: “This part of the process is rarely seen by consumers, which means that by the time a finished piece reaches a store or online platform, much of the early-stage waste has already been created and overlooked.”
Why production speed and volume make the problem worse
Rapid production cycles have created clear benefits for consumers who want fast access to new styles, but they have also placed significant strain on sustainability efforts. When clothing is produced at high volume, even the smallest inefficiencies are repeated at scale, meaning that what may appear to be minor fabric loss can quickly become significant waste.
When timelines are tight, pattern development often happens at speed, leaving less time to refine layouts or make the most efficient use of available materials. Frequent style updates create yet another layer of waste, as more collections require more sampling, more revisions and more designs that may never move beyond the development stage.
Across global supply chains, the impact builds. Fabric is sourced, transported and processed, yet a portion of it remains unused, creating a system where waste is unintentionally built into the process from the very beginning.
For fashion businesses operating in competitive markets, where creativity, speed and commercial pressures often collide, the challenge is not simply to produce more responsibly, but to rethink how garments are designed before production even begins.
The true cost of fabric waste
So, what is the true cost of this waste, and what does it mean for the global economy, both financially and environmentally?
The numbers are difficult to ignore and textile production is widely recognised as one of the world’s most polluting industries, generating roughly 1.2 billion tonnes of greenhouse gas emissions each year, while projections suggest that the fashion industry could consume nearly 25% of the world’s carbon budget by 2050.
There is also a significant financial impact. A report from Boston Consulting Group, Spinning Textile Waste into Value, estimates that unrecovered textile waste represents around $150 billion in lost raw material value every year.
However, the ethical concerns go far beyond cost and emissions. Wesley Hartwell, Course Leader MA / MFA Fashion and Director of the Regenerative Fashion Archive at the University of East London, says:
“The fashion industry often operates through extractive systems that generate significant material and cultural waste long before garments reach consumers. At the Regenerative Fashion Archive, we explore approaches aligned with the UN Sustainable Development Goals, particularly Responsible Consumption and Production, investigating how digital innovation, design methodology and collaborative research can reduce waste at the earliest stages of production.”
His comments highlight a growing recognition across London’s fashion and academic communities that sustainability cannot be treated as an add-on at the end of the production process. It must be embedded much earlier, in the decisions that shape how garments are conceived, developed and made.
How technology is changing pattern design
Thankfully, technology is beginning to offer practical solutions to this challenge, with digital tools reshaping how garments are designed, tested and produced.
These tools give designers the ability to plan with greater accuracy before a single piece of fabric is cut. Software can map out pattern layouts in ways that reduce unused space and limit offcuts from the start, helping brands make better use of their materials without slowing down the creative process.
Nick, concludes: “Technology can also reduce the need for repeated physical sampling by allowing teams to test, amend and refine designs digitally before committing to material use. This not only supports sustainability goals, but also helps brands reduce costs, shorten development timelines and make more informed production decisions.
“Solutions such as our own reflect this shift and as a start-up focused on reducing waste at its source, we’re using smarter pre-production processes to help brands rethink how clothing is made from the very beginning.
“For fashion businesses, this means less material loss, lower production costs and a more creative, responsible approach to garment development. More broadly, it shows how innovation emerging from London’s start-up and fashion ecosystem can help shape a more sustainable future for the industry.”
As pressure grows on brands to reduce their environmental impact, the design stage can no longer be overlooked. The future of sustainable fashion will not only be decided by what happens to garments after they are worn, but by the choices made long before they are ever produced.
