Reducing Waste in Small-Batch Manufacturing
Reducing waste in small-batch manufacturing solves two major problems: overproduction and environmental harm. By producing fewer items based on actual demand, manufacturers avoid surplus inventory and cut down on waste. The fashion industry generates 92 million tons of waste annually, but small-batch methods offer a way to address this issue while meeting consumer preferences for ethical and sustainable products.
Key strategies include:
- Material Selection: Using recycled fabrics, deadstock, and ethically sourced materials minimizes waste and supports sustainable practices.
- Production Techniques: Zero-waste pattern cutting and lean manufacturing reduce fabric scraps and improve efficiency.
- Made-to-Order Models: Producing only what’s purchased eliminates unsold inventory and storage costs.
- Post-Production Waste Management: Take-back programs, upcycling fabric scraps, and designing garments for recyclability extend material lifespans and reduce landfill contributions.
These methods not only reduce waste but also cut costs, improve profit margins, and align with growing consumer demand for sustainable products. For manufacturers, waste reduction is both a practical and profitable approach to improving operations.
How To Track Raw Materials In Your Warehouse When Doing Batch Production
Material Selection and Sourcing for Waste Reduction
In small-batch manufacturing, the materials you choose play a massive role in cutting waste. They’re the backbone of any smart waste reduction strategy, helping you balance sustainability with the quality your customers expect. By evaluating materials across their entire lifecycle, you can meet both environmental and business goals.
Using Recycled and New Materials
Recycled materials are a game-changer when it comes to reducing waste without sacrificing quality. For instance, recycled polyester not only keeps plastic bottles out of landfills but also cuts down on the need for virgin resources [8]. Take Patagonia as an example: in 2024, they’re incorporating recycled polyester and nylon into many of their products [10].
Some natural options are also worth considering. Organic cotton, for example, uses just 243 liters of water per T-shirt compared to the staggering 2,700 liters required for conventional cotton. Similarly, Tencel Lyocell, made from sustainably harvested wood pulp, offers benefits like superior drape and biodegradability [8][9].
When it comes to new materials, look for options produced with waterless processes or non-chemical-based dyes. While these might come with slightly higher initial costs, they align with the increasing demand for products that are genuinely sustainable [8][9].
Using Deadstock and Reclaimed Fabrics
Deadstock fabrics - those leftover, surplus, or deemed unsuitable for large-scale production - offer a practical way to cut waste. These materials help reduce the 92 million tons of textile waste generated annually while offering cost savings and creative opportunities [3].
Deadstock is often cheaper than newly manufactured fabrics and comes in limited quantities, making it perfect for creating unique, exclusive designs [2][3]. To make the most of these materials, ensure rigorous quality checks and partner with suppliers who specialize in circular resources [2].
Ethical Sourcing Practices
Ethical sourcing is a cornerstone of sustainable material selection. Alarmingly, 22% of cotton used by global brands comes from regions tied to severe human rights issues, highlighting the importance of choosing suppliers carefully [4].
Building long-term relationships with suppliers not only ensures consistent quality but also supports ethical production. Rather than chasing lower costs, focus on suppliers with certifications like Fair Trade, SA8000, or GOTS (Global Organic Textile Standard) [6][7]. Transparency is key - map your supply chain from raw materials to finished products to ensure every step aligns with your values. Consumer data backs this up: 66% of shoppers consider sustainability when making purchases, and 75% of millennials are willing to pay a premium for sustainable options [5].
The textile industry’s environmental impact is significant, contributing to 20% of industrial water pollution and 35% of microplastic pollution in oceans [2]. That’s why working with vendors who openly share their sourcing practices and sustainability efforts is so important. Additionally, collaborating with local manufacturers, seamstresses, and artisans not only ensures fair wages and ethical working conditions but also cuts down on transportation emissions [7].
At dorsaLi, we’ve made sustainable and ethical sourcing a core part of our mission. Every piece we create reflects our commitment to quality and environmental responsibility.
These material strategies naturally tie into production methods that further cut waste, creating a seamless approach to sustainable manufacturing.
Production Methods to Minimize Waste
Once sustainable materials are secured, the next step is refining production methods to cut down on waste. By combining smart material choices with forward-thinking techniques, manufacturers can reduce fabric scraps, energy consumption, and overproduction - without compromising quality.
Zero-Waste Pattern Cutting
Zero-waste pattern cutting (ZWPM) turns traditional garment-making on its head by eliminating fabric waste altogether. This approach merges pattern design with cutting techniques to ensure every bit of fabric is used.
Typically, conventional garment production wastes 15–20% of fabric due to inefficient pattern placement [11]. In fact, around 15% of textiles meant for clothing end up discarded during the cutting process [12]. This represents a significant loss, both in terms of materials and cost.
The secret to successful zero-waste cutting lies in understanding fabric constraints from the outset. Timo Rissanen, co-author of Zero Waste Fashion Design, highlights this critical point:
"The textile width is always a crucial consideration in zero-waste design. You can't design zero-waste without knowing exactly how wide the textile is. The textile width is the space within which you create zero-waste fashion design." [12]
Designers employ creative methods like folding, rotating, and tessellating patterns, alongside exploring alternatives such as draping, knitting, and crocheting to use only the required material. For example, the Redress Design Award has showcased pioneering techniques: Le Ngoc Ha Thu reimagined a yukata, creating a zero-waste pattern for a shirt, while Laura Krause hand-knitted a dress to her model’s exact measurements, completely bypassing traditional cutting and sewing [12].
Ada Zanditon, a fashion designer, offers this advice:
"Think before you cut and be inventive and experimental. Construct a zero-waste pattern or drape the textile. Sew or heat-seal the textile together. Knit and you will only ever use the necessary amount of material. Be inspired by origami." [12]
Starting with simpler projects can help designers build confidence in these methods. Modular designs, where pieces can be rearranged and reused, are another exciting area to explore. These techniques, combined with AI-assisted tools, are paving the way for smarter, leaner production processes.
Lean Manufacturing and AI Optimization
Lean manufacturing focuses on reducing waste and improving efficiency by analyzing every step of the production process - from material handling to packaging. By identifying where time, energy, or materials are being wasted, manufacturers can make targeted improvements.
AI technology takes this a step further by optimizing pattern layouts and fabric usage [13]. AI-driven automation has been shown to increase productivity by up to 40% and cut supply chain costs by 30% [15]. The AI-driven fashion market is expected to grow significantly, reaching $4.95 billion by 2028, with a projected annual growth rate of 40.2% [16].
One standout example is Stylumia, a fashion intelligence company based in Bengaluru. Stylumia has helped its clients cut garment production by over 60 million pieces while simultaneously increasing sales and profits. Their AI system identifies consumer trends in real time, allowing designers to make more accurate decisions about styles and colors - improving precision by up to 30% [17].
As Matthew Dwyer from Patagonia explains:
"Data should lead to an insight and an insight should lead to an action which is better informed than the one you took before." [18]
By integrating lean principles with AI tools, manufacturers can digitize their supply chains, creating a more agile and cost-efficient production system.
Benefits of Made-to-Order Production
Made-to-order production offers a game-changing solution to overproduction by ensuring only purchased items are manufactured. This approach eliminates unsold inventory, which often ends up in landfills, and reduces storage costs. It also allows for more customization, giving consumers tailored products while minimizing waste [1].
Small-batch production is another advantage of this model, enabling designers to experiment with new techniques and materials without the financial risk of large unsold inventories. Sandrine Devillard, a senior partner at McKinsey, notes:
"Shein's ability to execute small production batches and test them out with customers exceeds the capabilities of other retailers." [14]
Made-to-order systems also provide valuable insights into customer preferences. By directly linking demand to production, brands can fine-tune future designs and material choices. The industry is now shifting toward "on-demand local-for-local production." As Lutz Walter, an expert in textile innovation, explains:
"Highly digitised automated micro factories for clothing and fashion will be one important building block for on-demand local-for-local production which will make the wasteful long lead time offshore production model obsolete." [18]
Brands like dorsaLi are leading by example, using efficient made-to-order processes that align with the push for environmentally responsible practices. These forward-thinking production methods lay the groundwork for better waste management after production.

Circularity and Post-Production Waste Management
Even with the best production practices, some waste is inevitable. The challenge is to create systems that reclaim and reuse these materials instead of letting them end up in landfills. By focusing on post-production strategies, manufacturers can transform potential waste into resources, extending the lifespan of materials and minimizing environmental harm. These efforts build on earlier steps like smart material selection and efficient production methods, bringing the concept of a circular economy full circle.
Take-Back and Recycling Programs
Take-back programs provide a straightforward way to tackle textile waste by collecting used garments from customers and reintroducing them into the manufacturing process [20]. Instead of the traditional linear flow - manufacturer to consumer - these programs reverse the cycle, redirecting used items for recycling.
The scale of the textile waste issue is staggering. Kristy Caylor, founder and CEO of For Days, highlights the problem:
"We put 50 billion garments into landfill every year in the US" [19].
Traditional donation systems are limited in their impact, with 25% of textiles still ending up in landfills and 40–50% entering problematic global second-hand markets [20].
Effective take-back programs focus on measurable outcomes. For Days, for instance, runs a Take Back Bag program that recycles up to 95% of the clothing and textiles it collects. Each bag can divert up to 15 pounds of waste from landfills and reduce CO₂ emissions by as much as 92 pounds. Their results show that 50% of items are downcycled, 45% are resold, and only 5% are discarded as trash [19].
Other brands have also introduced successful take-back initiatives with customer incentives. For example:
- Girlfriend Collective: Accepts bras, leggings, and shorts for recycling and offers $15 in store credit [20].
- Universal Standard: Takes wardrobe items from any brand and provides $25 per recyclable item, up to $100 [21].
- Etiko: Focuses on footwear, offering $10 gift vouchers for sneakers and $5 for thongs returned through their program [20].
Transparency is key in these programs. Kristy Caylor advises:
"Look for companies that offer transparency: how much is collected, how much is 'recycled' and where the clothes go" [19].
Beyond take-back programs, there’s also great potential in repurposing leftover materials.
Upcycling Fabric Scraps
Garment manufacturing often generates significant fabric waste - up to 40% of the total fabric used. However, much of this waste can be upcycled into new garments, with certain leftovers, like spreading loss and excess fabric, reaching up to 80% upcycling potential [22].
Attraction, for example, has implemented a system to turn scrap waste into useful materials. In October 2024, the company partnered with Mécanec Transformation Textile (MTT) Inc. to shred textile scraps, converting them into padding, nonwoven materials, and insulating products. This initiative will divert around 30 tons of textile waste from landfills annually [23].
Julia Gagnon, Vice President of Operations at Attraction, shared the company's drive for this initiative:
"We are very proud of this new development. We have been looking for ways to upcycle our textile scraps for several years. It was unacceptable to send the remnants of our quality organic cotton and recycled polyester apparel to the landfill" [23].
She also outlined their long-term vision:
"The ultimate goal would be to eventually use our own textile scraps to create a locally made recycled yarn that could then be used to manufacture our Ethica products" [23].
Elsewhere, Ameramark in Santa Ana, CA, takes a different approach. At their Ensenada, Mexico facility, they upcycle scraps into products like scrunchies and cosmetic bags, demonstrating how waste can inspire entirely new product lines [23].
Designing for Recyclability
To truly close the loop, garments must be designed with recycling in mind. Currently, less than 1% of clothing materials are recycled into new clothing, largely because most garments are not made to be disassembled and processed [24].
Improving recyclability starts with fabric choices and construction methods. Monofiber fabrics, or those with fewer fiber types, are easier to recycle. On the other hand, blended textiles pose significant challenges for mechanical recycling, which involves cutting and shredding fibers.
Certain design features can simplify or complicate the recycling process. For example, avoiding components like membrane structures, padding, film prints, and laminations makes garments easier to recycle. When these elements are necessary, they should be designed for easy removal. Accurate labeling of materials is also critical to ensure proper recycling [24].
A standout example is Unspun, a Hong Kong-based denim brand. They’ve partnered with Resortecs to use dissolvable stitching threads, enabling them to recover fabric and trims from worn jeans. Through their take-back program, these materials are then used to create new products [24].
Here’s a breakdown of recycling methods and their challenges:
| Method | Description | Challenges |
|---|---|---|
| Mechanical Recycling | Shreds textiles into fibers for new yarn or filling. | Fiber degradation, limited for blends, and poor contaminant removal. |
| Chemical Recycling | Breaks down fibers into monomers or polymers using chemicals. | Energy-intensive, requires specific waste streams, and involves chemical management. |
| Biological Recycling | Uses enzymes or microbes to break down fibers. | Still in development and faces scalability issues. |
The Redress Design Award sums it up well:
"Designing for recyclability is a strategy that ensures products never become 'waste', but instead allows for closed-loop material recovery" [24].
Brands like dorsaLi, known for their commitment to high-quality craftsmanship, are well-positioned to integrate these principles. By combining durable construction, recyclable materials, and transparent take-back systems, small-batch manufacturers can create production models that align with both environmental and financial goals. Designing for recyclability ensures a sustainable lifecycle for every product, keeping waste out of landfills and resources in use.
Cost Impact and Profitability of Waste Reduction
Reducing waste isn’t just about cutting costs - it’s also about building a more resilient and future-proof business. For small-batch manufacturers, waste reduction strategies lead to steady savings that improve profitability over time while helping businesses weather market fluctuations. Beyond the environmental benefits, these practices align with sustainable business values embraced by brands like dorsaLi.
Bradford Arick from RoadRunner highlights this dual advantage:
"Zero Waste is no longer simply a sustainable choice for industries. It has become a shrewd business strategy with the capability of protecting future profitability and ensuring greater affordability with waste management operations." [25]
The numbers back this up. Over the past three decades, tipping fees for waste disposal have increased by 133% [25]. This makes waste reduction not just an ethical responsibility but also a financial necessity. Meanwhile, consumer trends are shifting - nearly 40% of customers now prefer sustainable products, and over a third of global consumers are willing to pay more for sustainability [25].
Lowering Material and Disposal Costs
One of the clearest ways to save money is by cutting material waste and reducing disposal fees. For example, traditional textile cutting methods often waste 15–20% of fabric due to unusable gaps [27]. For a small manufacturer spending $10,000 on fabric each month, this means $1,500–$2,000 is effectively thrown away.
Big players in the industry show how impactful waste reduction can be. Unilever, for instance, achieved zero waste to landfill across 242 factories in 67 countries, saving more than $225 million in the process [26]. Siemens also made strides by cutting waste production by 70% at one facility, saving over $1 million annually [26].
Smarter sourcing and production techniques also play a big role. Using deadstock fabrics - materials left over from other production runs - can significantly lower costs compared to newly manufactured materials. Made-to-order production, on the other hand, eliminates the risk of unsold inventory, a common challenge in traditional manufacturing.
Zero-waste pattern cutting is another game-changer. By maximizing fabric usage, manufacturers can significantly reduce waste. Some even go a step further, repurposing leftover scraps into accessories or other products, ensuring minimal waste throughout the production process [27].
Savings also come from reduced disposal fees, lower storage costs, and more efficient waste management systems. Over time, these efficiencies add up, creating a compounding financial benefit [25].
Comparison Table of Waste Reduction Methods
Different approaches to waste reduction come with their own costs and benefits. Here’s a breakdown to help manufacturers determine what might work best for their operations:
| Method | Initial Investment | Material Cost Savings | Operational Complexity | Long-term ROI | Best For |

| Chemical Recycling | High | Variable | Very High | Variable | Large-scale operations |
*While exact savings for deadstock sourcing aren’t always specified, the cost reductions are often substantial compared to new materials.
These strategies offer both immediate savings and long-term financial benefits. For smaller manufacturers, zero-waste pattern cutting is an accessible starting point, delivering quick material savings with minimal upfront costs. Deadstock sourcing is another effective option, especially for businesses that can establish a reliable supply of leftover fabrics.
Made-to-order production stands out as a particularly strong option for brands like dorsaLi, which prioritize quality and custom craftsmanship. By producing only what’s needed, this model eliminates the financial burden of unsold inventory and aligns perfectly with the ethos of creating timeless, high-quality products.
Take-back programs, meanwhile, provide an opportunity to generate additional revenue by recycling or upcycling returned items. They also have the added benefit of fostering stronger customer loyalty, making them a win-win for businesses looking to combine profitability with sustainability.
