Dantoy
The Dantoy are made from bio-plastic - 95% from plants, specifically the waste leaves/stalks of sugarcane. A much lower carbon footprint than petro-plastic, but with the same durability and moldability. These toys won't biodegrade in your garden / sandpit or at the beach; they'll last as long as you want them and eventually can be recycled (because, unlike many non-recyclable petro-plastic toys, they're single-material).
