If you have old cashmere items you no longer need, consider these responsible options for disposal. You can explore recycling programs, donate to local thrift stores or charities, repurpose through DIY projects, sell or give away online, check with cashmere brands for recycling initiatives, or use textile banks if available in your area. Ensure the items are clean and in decent condition before donating or recycling, and be aware of any specific guidelines set by organizations.
