Sustainable Material Sustainable Manufacturing Sustainable Mind World Class Recognition SUSTAINABLE MATERIAL Rubber trees PlanToys® are made from natural rubber wood trees that no longer produce latex. To keep the wood pure, no fertilizer is added to the soil three years prior to cut the trees down. Chemical-Free Kiln-Dried To strengthen the wood, PlanToys® uses a chemical-free kiln-drying process. PlanWood PlanWood™ is another high quality, safe and sustainable material in our toy-making process. This material will be used in harmony with our solid rubberwood. Non-Formaldehyde Glue PlanToys® is assembled using a certified E-Zero formaldehyde free glue in place of traditional toxic wood glue. Organic Color Pigment PlanToys® commits itself to find the best eco-friendly material. The organic color is not only good for children but also for our environment. Water-based Dyes PlanToys® does not use chemical dyes containing lead or any other heavy metals. Soy Ink and Recycled Paper Recycled paper and Soy ink are used for our printed materials. Soy ink is more readily biodegradable and can be recycled more efficiently than standard chemical ink.
