PlanToys is a toy manufacturer orignated in Thailand. It makes its toys out of rubberwood, a sustainable by-product of the latex industry's harvesting of trees used for natural rubber production once their productivity declines. Using the trees as a resource in this way for wooden toys made by PlanToys is considered environmentally responsible. PlanToys also uses preservative-free rubberwood and non-formaldehyde glues, as well as recyclable packaging and safe, non-toxic water-based dyes. Their products are marketed as "green," and are recognized as such by various buying guides endorsing green products for children.
