We looked into bio plastics and bamboo for both the tube and closing cap. It’s easy enough to find bamboo-based biodegradable tubes but the closing cap is pretty much always still normal plastic. Biodegradable plastic also has its controversies: it won’t degrade in clean ways outside of commercial composting facilities. There’s also a bamboo-based plastic controversy around toxicity of the product in e.g. bamboo-plastic cups.
