How do you approach the challenge of integrating sustainability into the core practices of established fashion brands?
As a sustainability fashion expert, I help brands incorporate sustainable strategies to benefit the environment and become more resilient for the future. Working with established brands is challenging due to their rigid structures and traditional ways of operating.
Often, they have been in business for a long time, making it easier to continue with business as usual rather than implement change. Therefore, I focus on incorporating practices that are environmentally friendly, economically viable, and socially responsible. Here are the strategies I recommend:
- Adopt a circular design philosophy: Shift from traditional linear models to circular, regenerative systems. This involves creating products that can be reused, recycled, or repurposed at the end of their lifecycle, thus minimising waste and pollution.
- Material choices and product design: Select sustainable raw materials and design products for longevity. Avoid blends that are difficult to recycle, like cotton-polyester, and opt for mono-material fabrics instead.
- Consumer-centric approach and product-as-a-service: Focus on what consumers actually need and consider offering products as a service. This strategy can help reduce overconsumption and mass production.
- Education and transparency: Build trust with consumers through education and transparency about your sustainability practices. Sharing the story behind each product helps consumers understand and appreciate the efforts towards sustainability.
- Technology: Embrace digital transformation, including blockchain for traceability, and incorporate digital components in fashion. This could include virtual reality and experience-based offerings, reducing the need for physical products.
- Post-consumer strategies: Implement strategies for the post-consumer phase, such as reselling, restyling, or offering repair services to extend the lifespan of products.
- Sustainable packaging: In addition to product design and manufacturing processes, focus on sustainable packaging solutions. Use materials that are recyclable, biodegradable, or made from renewable resources. Minimizing packaging and using designs that reduce waste are also crucial. Informing consumers about proper disposal or recycling of packaging can play a significant role in minimising environmental impact.
- Develop guidance material for suppliers: Work on reducing their energy and water use and waste generation.
How do the bio-based leather alternatives you're working with compare to traditional leather in terms of durability and aesthetics?
As a sustainable fashion expert, I often encounter questions about the viability of bio-based leather alternatives compared to traditional leather. The leather industry has faced a paradox in recent years. Despite an oversupply of cattle hides due to increased meat consumption and global population growth, the price and demand for leather have decreased. This situation has led to an unfortunate scenario where hides are not utilised efficiently, raising concerns about waste and sustainability. Leather, historically valued as a by-product of the meat industry, now faces competition from synthetic materials favoured for their cost-effectiveness, ease of production, and alignment with vegan principles.
However, the shift towards synthetic materials, predominantly derived from petrochemicals, is not without its drawbacks. These materials contribute significantly to plastic pollution and lack the biodegradability of leather. The environmental impact of synthetics is a growing concern, despite their perceived eco-friendliness.
In this context, bio-based leather alternatives have emerged as a promising solution. These materials aim to mimic the durability and aesthetics of traditional leather while addressing some of the environmental concerns associated with both leather and synthetic materials. From a sustainability perspective, bio-based alternatives are designed to be less resource-intensive and more environmentally friendly than traditional leather.
When it comes to durability, bio-based leather alternatives are continually improving. While they may not yet match the longevity of high-quality traditional leather, advancements in technology are closing this gap. In terms of aesthetics, these alternatives offer a variety of textures and finishes that are increasingly similar to traditional leather. However, the biggest drawback of leather alternatives is that consumers feel less emotional attachment and perceived value toward a handbag made of 'apple waste'. For example, with a high-end leather handbag, there is an emotional attachment, and the look improves as the leather ages, creating the possibility for it to last indefinitely and be passed down to the next generation.
In conclusion, the comparison between bio-based leather alternatives and traditional leather is complex and multifaceted. While I still prefer natural leather, especially if it is tanned following responsible production practices and has a transparent supply chain, I understand the importance of designers branching out and including sustainable leather alternatives, such as recycled leather, apple leather, and so on, in their collections.
Bio-based leather materials have often been seen as plastic-bio-leather blends. Do you think this description is fair?
The characterization of bio-based leather materials as plastic-bio-leather blends provides a simplified overview and doesn't entirely cover the innovation and diversity within this sector.
Here’s my detailed perspective:
- Bio-Based Polyurethane Leather Alternative: Bio-based PU leather alternatives are increasingly crafted using renewable resources like sugar, corn, rapeseed, soy, and palm. These alternatives can replace a significant portion of the traditional petrochemical-derived polymers in PU, reducing environmental impact. This evolution represents a significant shift towards more sustainable practices in alternative materials.
- Plant-Based Leather Alternatives: The composition and production methods of plant-based leather alternatives like Piñatex, apple “leather”, and cactus “leather”, as well as recycled leather, are quite diverse. Here are a few examples:
- Piñatex: This material is made from 72% pineapple leaf fiber and 18% polylactic acid (PLA), making it predominantly natural. Under certain conditions, Piñatex is also biodegradable, offering an eco-friendly alternative to conventional synthetic leathers.
- Apple Leather Alternative: Apple leather is a biomaterial created using organic waste materials from the apple industry, primarily apple waste. It undergoes a process where the apple waste is dehydrated to a powder, which usually amounts to 20% or 30% of the overall composition. It is then combined with polyurethane to enhance durability and longevity.
- Cactus Leather Alternative: This material is made from mature cactus leaves. The leaves are processed to extract proteins and fibers, which are then used to make an organic bioresin. It is then combined with polyurethane to enhance durability and longevity.
- Mycelium-Based Materials: Leather alternatives created from the mycelium of fungi are groundbreaking developments in this field. Produced in a lab, they consume less water and produce fewer greenhouse gases compared to animal leather, marking a significant step towards eco-friendly leather alternatives.
In conclusion, while the term 'plastic-bio-leather blends' does apply to some bio-based leather materials, it overlooks the range of materials and manufacturing processes that contribute to the field's sustainability and innovation. With a growing focus on reducing environmental impact, the use of renewable resources, and the development of natural material alternatives, the bio-based leather industry is improving year after year to use less plastic in its mixes.
