Coreva is a stretch material made from natural rubber, it is biodegradable. It is currently used only with cotton to make a stretch denim, developed by Candiani Denim. Sorona has also developed a more environmental friendly stretch material, but it us just 37% bio-based.
For stretch material, instead of using synthetic stretch such as elastane/lycra, try to work with the way a garment is knitted instead, and use natural materials.
