Interview Questions for Fashion Sustainability

In the fashion industry, a circular economy moves away from the traditional ‘take-make-dispose’ linear model towards a cyclical system. Instead of discarding clothes after use, the circular economy focuses on keeping materials and products in use for as long as possible, extracting maximum value, then recovering and regenerating products and materials at the end of each service life.

Think of it like this: Imagine a closed loop. Instead of creating new clothes from raw materials, we prioritize extending the life of existing garments through repair, reuse, and resale. Once a garment is truly at the end of its life, it’s disassembled, and its components are recycled or upcycled into new products, minimizing waste and resource depletion. This includes innovative solutions like textile-to-textile recycling, where old clothes are transformed into new fabrics.

For example, brands are now investing in clothing rental services, promoting clothing swaps, and designing garments for easy disassembly and material recovery. This shifts the focus from ownership to access and responsible disposal, creating a more sustainable and resource-efficient fashion ecosystem.

Implementing sustainable practices in the fashion supply chain faces significant hurdles. Three key challenges are:

• Lack of Traceability and Transparency: The complex and often opaque nature of global fashion supply chains makes it difficult to track materials and labor practices throughout the production process. This makes it hard to ensure ethical sourcing and environmental responsibility at every stage.
• High Initial Investment Costs: Transitioning to sustainable materials, technologies, and processes requires significant upfront investment. Smaller brands and businesses, especially, may struggle to afford these changes, hindering widespread adoption.
• Consumer Behavior and Demand: Consumers often prioritize price and fashion trends over sustainability, leading to high demand for cheap, fast fashion and a low demand for more sustainably produced, higher-priced garments. This lack of consumer awareness and willingness to pay a premium for sustainable fashion can limit its market viability.

Textile production carries substantial environmental impacts across its lifecycle. These include:

• Water Pollution: Dyeing and finishing processes release large amounts of wastewater containing harmful chemicals into water bodies, damaging aquatic ecosystems.
• Greenhouse Gas Emissions: The production of synthetic fibers like polyester relies heavily on fossil fuels, contributing significantly to greenhouse gas emissions. Cotton cultivation, while natural, also requires substantial water and pesticide use, impacting the environment.
• Land Use and Deforestation: Cotton farming requires extensive land, sometimes leading to deforestation and habitat loss. Other natural fibers also have associated land use impacts.
• Waste Generation: Textile waste from manufacturing and consumer disposal creates massive landfill burdens, contributing to pollution and resource depletion.

These impacts highlight the urgent need for innovative solutions and responsible production practices throughout the textile supply chain.

Life Cycle Assessment (LCA) is a crucial tool for evaluating the environmental impact of a product throughout its entire life cycle, from raw material extraction to disposal. In the fashion industry, LCA helps brands identify environmental hotspots in their supply chains.

By analyzing factors like water consumption, energy use, greenhouse gas emissions, and waste generation at each stage, LCA provides a comprehensive picture of a garment’s environmental footprint. This data enables brands to pinpoint areas for improvement and develop strategies to reduce their environmental impact. For instance, an LCA might reveal that a particular dyeing process is a major source of water pollution, prompting the brand to switch to a more sustainable alternative.

Ultimately, LCA helps to drive informed decision-making, promote transparency, and support the development of truly sustainable fashion products. It fosters continuous improvement and allows for credible environmental claims.
