92 million tons of old jeans and discarded t-shirts are building the future - literally. In London, a groundbreaking idea is converting the fashion industry's waste into a solution for the construction sector. Architecture student Clarice Merlet has connected these two fields with a new innovation: bricks made from discarded textiles. In 2017, Merlet realized the construction industry’s huge environmental impact and turned to discarded clothing as a solution. By 2019, her initiative, 'Fabric', was turning old fashion into new building materials. Here's why Fabric's innovation is capturing attention across industries: > Dual impact:  ‘Fabric’ addresses two major environmental issues at once: the fashion industry produces 92 million tons of waste each year (Global Fashion Agenda) and construction causes 39% of global carbon emissions (World Green Building Council). This solution tackles both problems together. > The process is remarkably straightforward: Collect and sort discarded clothing Shred the textiles into fibers Mix with eco-friendly binding agents Compress the mixture into molds Air-dry to create solid, durable bricks > These aren't just bricks. They're building blocks for furniture, décor, and architectural elements, opening new avenues for sustainable design. > These fabric bricks retain the colors of original textiles, eliminating the need for additional dyeing and further reducing environmental impact. > With global textile waste expected to rise to 148 million tons by 2030 (Global Fashion Agenda), Fabric is a prime example of the circular economy in action. This innovation highlights that cross-industry collaboration can lead to unexpected environmental solutions, and waste from one sector can become valuable in another. As fashion professionals, Fabric's story challenges us to think beyond conventional boundaries. How can we reimagine 'waste' in our field? What unexpected partnerships might lead to the next sustainability breakthrough? #SustainableFashion #CircularEconomy

Your next outfit could be on your grocery list. Sounds unbelievable, right? But it’s already happening. The skins, seeds, and stems left behind in winemaking are being transformed into beautiful, durable textiles. Grapes that once went into glasses are now going into garments - turning“waste” into durable raw material. And it’s not just wine. Coffee grounds, olives, apple peels, pineapple skins - innovators like Planet of the Grapes, Arda Biomaterials Oleatex, PINATEX AIELO SL, MycoWorks Sway, Organoid are experimenting with everything we throw away, turning it into shoes, jackets, handbags, and everyday essentials. Why does this matter? Because fashion is one of the most polluting industries in the world. Leather and polyester carry enormous environmental costs, animal cruelty, and fossil fuel dependence. But when fashion starts to look at food waste as fabric, we unlock circular systems where nothing is discarded and everything has worth. It’s culture, climate, and creativity stitched into one. So the next time you raise a glass or at the grocery store, imagine nature’s produce as a design breakthrough, and the future of fashion.

Around 9 billion coconut husks are discarded or burned each year 🌎 Coconut husks, an abundant agricultural byproduct, are typically burned or discarded despite their potential for industrial use. One emerging application is their use as a natural alternative to expanded polystyrene (EPS) foam in insulation for coolers and packaging. As industries face increasing pressure to reduce environmental impacts, the use of coconut-based materials presents a promising solution aligned with circular economy principles. The fibrous structure of the coconut husk provides adequate thermal insulation, moisture resistance, and durability, making it suitable for cold-chain and consumer applications. When processed and incorporated into product design, it can replace synthetic foam with a renewable, biodegradable input—contributing to reduced dependency on fossil fuel-based materials and diverting waste from open disposal. Integrating coconut-based insulation into commercial production can support circularity by creating value from organic waste, reducing virgin material extraction, and promoting more regenerative supply chains. However, this transition is not without challenges. Consistency in material quality, scalability of supply, and the development of processing infrastructure remain key considerations. Companies must also assess cost competitiveness and ensure that performance standards are reliably met across different use cases. There are additional concerns around lifecycle impacts, including the energy and resources required for fiber treatment, and the risk of limited end-of-life recovery pathways if materials are not properly composted or reused. These factors highlight the need for robust material design, responsible sourcing, and clear communication of disposal practices to end users. Despite these risks, the use of coconut husk insulation illustrates how circular economy thinking can drive material innovation. By repurposing waste streams into viable commercial inputs, companies can enhance the sustainability of their products, build resilience in supply chains, and meet growing stakeholder expectations for environmentally responsible solutions.

The textile industry is at a pivotal moment. Increased consumption, rapid fashion cycles, and resource constraints have turned waste into a major challenge. However, this issue also offers a significant commercial opportunity for those prepared to rethink core practices. Sustainability is central to our ethos. It is a responsibility that should guide how we design operations, develop supply chains, and measure long-term value. We are guided by a simple principle: we only take what we can give back. This approach guides how we manage waste, energy, water, and materials across our value chain. From the outset, we made a strategic decision to treat waste as the starting point of a new lifecycle. Each year, we recycle 1.83 billion PET bottles into 51,850 metric tonnes of recycled polyester fiber. Instead of ending up in landfills or the ocean, this material becomes high-performance yarn that meets industry standards. Recycled polyester now represents nearly 50% of our total fiber use, proving that circularity can scale without sacrificing quality or cost-effectiveness. Our boilers are transitioning from coal to biofuels made from agricultural residues. Renewable sources now supply nearly 70% of our total power, supported by a 60 MW partnership with Adani. All manufacturing units fully recycle water under a zero-liquid-discharge framework. Textile waste is now addressed across its lifecycle. Pre-consumer waste is reused in production, and post-consumer garments are recycled, reused, or rented. Fiber-to-fiber technology is accelerating this transition. As raw material costs rise and regulations tighten, circularity becomes a strategic advantage. The future of textiles will favour those who treat waste as a resource and responsibility as a core aspect of leadership. #recycling #sustainability #textilewaste #manufacturing #textiles #viksitbharat

From Weed to Wonder. Designers and innovators are thinking outside the box—or in this case, outside in the garden—as they turn to weeds for sustainable packaging solutions. Instead of seeing these plants as nuisances, they're tapping into their unique properties to create eco-friendly alternatives to traditional packaging materials. One exciting approach is the creation of weed-based bioplastics. Innovators are extracting cellulose and polymers from weeds to make packaging materials that are both biodegradable and compostable. Some designers are getting creative with the sturdy and flexible fibres found in certain weed species to reinforce their packaging. This makes the packaging more durable and highlights the versatility of these often underestimated plants. Weed-based paper, adhesives, inks, dyes, and films are also being explored for various packaging applications. By considering weeds as a valuable resource, designers are not only reducing the environmental impact of packaging but promote local sourcing and community initiatives. Take for example soft rush, a common weed found in Dutch wetlands. In the Netherlands, state forestry removes thousands of kilos of the soft rush each year. Currently, the only use is conversion of the soft rush into biogas through fermentation, otherwise, the strands are used to improve agricultural soil that contains a lot of sand. While it's often seen as a nuisance, Don Kwaning saw potential where others saw a problem and decided to explore this common weed's potential. His approach was simple—by separating soft rush into its pith and fibres, he opened up a whole new world of possibilities. To create packaging, he ingeniously transforms the pith into a lightweight, foam-like material. Its inherent qualities enabling it to be compressed into a substance resembling the widely used MDF, all without the need for binding agents. His versatile material offers exceptional protection in various forms, ranging from solid blocks to long, string-like structures, making it an ideal choice for both packaging and storage applications Through curiosity and an ability to connect seemingly unrelated elements, Kwaning has not only created useful sustainable products from a pesky weed, but opened the door for an entirely new material option for a range of manufacturing markets. Challenges our notions of waste and resources and reminds us that with a little imagination, even the most unlikely materials can be transformed into something beautiful and eco-conscious. Can you envision a future where materials like these are standard rather than the exception—what steps would be required to make them commercially viable and widely adopted? #packaging #sustainablepackaging #sustainabledesign #productdesign #sustainability 📷Don Kwaning

♻️ From Beer to Biodegradable Fashion: Brewing Waste Finds New Life in Textiles What if the yeast left behind in breweries could help solve fashion’s sustainability crisis? Researchers have developed biodegradable fibres spun from waste yeast proteins, offering a compelling alternative to cotton, wool, and polyester. 🔑 Why this matter: Cotton demands enormous water and land resources. Polyester sheds microplastics into our environment. Wool is costly to produce and raises animal welfare concerns. By contrast, yeast-based fibres: Repurpose brewing and pharmaceutical waste streams. Are reportedly stronger than natural fibres. Can be manufactured for $6/kg vs. $10–12/kg for wool. Are biodegradable, reducing long-term pollution. Imagine sweaters as soft as wool, but woven from the byproducts of beer-making. This innovation not only closes industrial loops but also points toward a circular economy in fashion. 👕 The pilot-scale demonstration has already produced over 1,000 pounds of material, showing real potential for scaling. 💡 Sustainable fashion doesn’t just mean new fabrics - it means rethinking waste. Turning brewing byproducts into clothing fibres is a powerful example of how chemistry and circular design can reshape industries. #sustainablefashion #circulareconomy #materialsscience
