Each needle box is made with biodegradable sugar cane fiber that is both recyclable and compostable. The needle and guide tube pouch packs are made from PET, or no. 1, plastic, and is the most widely recyclable plastic available. You may wish to double-check with your community curbside recycling program, but typically PET plastics are accepted. Otherwise, the pouch packs can easily be recycled at your local zero-waste recycling depot.
