The textile industry is a cornerstone of India’s economy, providing employment and producing goods integral to our daily lives. However, it is also a major contributor to environmental pollution, consuming vast amounts of water and energy and generating significant waste. Did you know that the textile industry is responsible for 10% of global carbon emissions and 20% of global wastewater? It’s clear that there’s a pressing need for sustainable solutions in this industry. But there’s good news – there are already overlooked methods that are driving sustainability in the textile industry!
Here, we explore some overlooked approaches driving sustainability in India’s textile sector.
The textile industry, ranking as the second largest sector in the global trade market, is projected to grow from USD 920 billion in 2018 to USD 1,230 billion by 2024. Despite its lucrative potential, the industry poses significant environmental challenges, necessitating strict monitoring and adherence to guidelines. Sustainable fashion aims to create thriving ecosystems and communities by increasing the value of local production, extending material lifecycles, valuing timeless garments, reducing waste, and minimizing environmental harm. Additionally, it seeks to educate consumers about environmentally friendly practices and promote green consumption.
Sustainability in the textile and clothing industry now extends beyond using organic materials and efficient processes. The textile supply chain consumes vast amounts of water and energy and involves the use of numerous chemicals and harmful substances. The discharge of hazardous waste by many textile industries threatens natural ecosystems. Therefore, adopting environmentally friendly manufacturing methods and utilizing natural resources responsibly are crucial to sustaining both the textile industry and the environment.
The following practices have long been overlooked, and are steppingstones in driving sustainability in the textile industry.
Water is essential in textile manufacturing, especially in dyeing and finishing processes. Traditionally, these processes use large amounts of water and release heavily polluted wastewater. However, the adoption of closed-loop water systems is changing this scenario.
Closed-loop water systems treat and recycle water within the manufacturing process, significantly reducing freshwater consumption and wastewater discharge. These systems use advanced filtration technologies to remove dyes, chemicals, and other contaminants from the water, allowing it to be reused multiple times. By implementing closed-loop systems, textile manufacturers can save a lot of water and reduce their environmental impact. To quote one, Tirupur, a major textile hub in Tamil Nadu, has successfully implemented such systems, significantly reducing its water footprint.
Digital printing technology is transforming the textile industry by offering a more sustainable alternative to traditional dyeing and printing methods. Conventional textile printing involves multiple steps, all of which consume large quantities of water, energy, and chemicals. In contrast, digital printing simplifies this process, leading to significant environmental benefits.
Digital printing uses less water and fewer chemicals, as it directly applies the ink to the fabric without the need for extensive pre- and post-treatment processes. This technology also reduces waste by allowing for precise color application and eliminating the need for excess dye. Furthermore, digital printing enables on-demand production, reducing overproduction and minimizing textile waste. The Indian textile industry, especially in regions like Surat and Ludhiana, is gradually adopting digital printing to enhance sustainability.
The widespread use of synthetic fibers like polyester and nylon has led to the problem of microplastic pollution. These fibers shed tiny plastic particles during washing, which eventually end up in oceans and water bodies, harming marine life and ecosystems. To combat this issue, the development and use of biodegradable textiles are gaining momentum.
Biodegradable textiles are made from natural fibers, such as organic cotton, hemp, and bamboo, which decompose naturally without leaving harmful residues. These materials offer an eco-friendly alternative to synthetic fibers, reducing the environmental impact of textile waste. Innovations in biotechnology are also leading to the creation of new biodegradable fibers from renewable sources, such as algae and fungi, further enhancing the sustainability of the textile industry. Indian startups and researchers are exploring these materials, aiming to reduce the environmental footprint of the textile sector.
The textile manufacturing process is energy-intensive, relying heavily on fossil fuels for powering machinery and heating processes. Transitioning to energy-efficient machinery can significantly reduce the industry’s carbon footprint and lower operational costs.
Modern textile machinery is designed to optimize energy consumption through advanced engineering and automation. For example, new-generation dyeing machines utilize lower temperatures and shorter cycles, reducing energy usage by up to 50%. Similarly, energy-efficient spinning and weaving machines incorporate regenerative braking systems and variable speed drives, minimizing power consumption.
By investing in such machinery, textile manufacturers can enhance their sustainability efforts while maintaining production efficiency. In India, regions like Coimbatore and Ahmedabad are adopting similar energy-efficient technologies to stay competitive and sustainable.
In the textile industry’s quest for sustainability, advanced technologies are being deployed to transform its supply chain.
For instance, Artificial intelligence (AI) driven optimization can reduce material waste by up to 15% and improve energy efficiency by 10-20% in textile manufacturing processes. This percentage can vary widely depending on factors such as the type of AI implementation, the complexity of manufacturing processes, the baseline efficiency levels, and other operational variables unique to each factory or production environment.
Textile recycling poses challenges due to fabric complexity, but technological progress has spurred innovative approaches like chemical and mechanical recycling. AI-driven automated sorting systems can segregate textiles based on fiber type, aiding efficient recycling processes. boosting recycling rates annually.
The Internet of Things (IoT) allows real-time monitoring and control of manufacturing equipment, cutting resource usage and pinpointing inefficiencies.
Implementing IoT electricity meters and smart metering systems can help textile factories monitor and optimize their energy consumption in real time. These devices provide real-time data on energy use, enabling companies to identify inefficiencies and take corrective actions immediately. By reducing unnecessary energy consumption, factories can significantly lower their carbon footprint.
Water management is another critical area where IoT solutions can make a difference. Automatic water level controllers can ensure that water usage is optimized, and waste is minimized. By precisely controlling water flow in various processes, these controllers help conserve water, a precious resource in textile manufacturing.
Supply chain transparency and traceability are critical for ensuring ethical and sustainable practices in the textile industry. Consumers are increasingly demanding information about the origins of their products, including the conditions under which they were made and the environmental impact of their production. Blockchain technology offers a powerful solution to meet these demands.
The textile industry is at a crossroad, facing increasing pressure to adopt sustainable practices and reduce its environmental impact. While well-known solutions like organic cotton and recycling programs are essential, these overlooked methods offer significant potential for driving sustainability in the industry. As the industry continues to evolve, it is crucial to explore and implement diverse strategies to create a more sustainable future for textiles.
