There are many, I believe the best ones are TUV certified water-biodegradable (‘OK Biodegradable Water’ cert). It’s means it’s 100% biodegradable and non-ecotoxic to a high standard, with at least 90% fully biodegrading in fresh water in 56 days or less, and confirms it does not biodegrade into microplastics - which some ‘bioplastics’ do.
‘BioGlitter’ is one example, a British invention now owned by a German company and made in Germany. From quick research it seems to be made primarily of Eucalyptus (leaf?) cellulose and wood pulp.
