New Dutch traffic signs made out of rice skin
The Dutch Ministry of Waterways and Public Works (Rijkswaterstaat, RWS) is proud to announce that 300 of the 4 000 new traffic signs along the Dutch highways already are ‘bio-based’. They’re no longer made of environmentally unfriendly aluminum. They’re produced out of a waste product of rice.
Since the recent introduction of the 100 km/hour speed limit on the Dutch highways during the day, the Dutch government had to install 4 000 new traffic signs to indicate the new measure. Most of them still are made of aluminum. However, the authorities were looking for a more sustainable solution. “Sustainability is a priority to us, and we want to produce as little waste as we possibly can,” says Diederik Fleuren of RWS.
The 300 new traffic signs that are already installed are the first of a series of sustainable and environmentally friendly signs that will be used in the coming years. “We applaud the use of natural products like rice skin and bamboo,” Fleuren continues. “As long as it’s recyclable and not harmful to the environment.”
The idea for the product comes from Rolf Lebbink, owner of Textline Reclamecentrum. He had been looking for a suitable and more environmentally friendly material to produce information boards. Then, suddenly he discovered a unique and circular material. “This board material is for 60% made out of rice skin, the waste product of the most popular food in the world.”
The rice skin is mixed with 22% of stone salt and 18% mineral oil. The result is a unique product that is 100% recyclable. It is also used for boats and terraces as a replacement for teak wood.
