Silk production from cocoons raises various sustainable issues as it is high-energy and water-intensive processing. Conventional silk production is not sustainable as it generates high volume of greenhouse gases due to consumption of large amounts of coal power to generate required energy to maintain boiling water and steam for production. Not only that a lot of synthetic dyes used during coloring of silk, pupae waste and untreated waters are regularly dumped into environment. The main environmental benefit of silk is that it is biodegradable and not derived from fossil fuels like other synthetic fibers so it doesn’t shed microplastics into the environment. This chapter explains the use of renewable sources of energy like solar heaters for generation of steam for various processes, mechanization, and automation for better energy efficiency in various processes of silk, viz., cooking, reeling, weaving, dyeing, etc. Use of eco-friendly dyeing processes, finishing of silk, digital printing, and reuse and recycling of water systems are employed to reduce the carbon footprints. Efforts are also made to minimize the dumping of silk waste in landfills by making spun silk, or utilizing it for other applications like biomaterials, cosmetics, crafting, wadding, fertilizer, poultry/fish feed, etc. By adopting sustainable silk production practices, the industry can significantly reduce its environmental impact and promote the well-being of silk-producing ecosystems.
