Garden twine is far better to support your runner beans that those plastic green ties, which can harm wildlife and birds, if they fly away.
Never leave any kind of twine, string or ribbon in gardens (biodegradable or not). Because birds may take it to make nests, and it can strangle or tangle chicks or other garden wildlife.
If growing food, learn how to make gardens safe for pets (includes indoor plants to avoid).
