Mizuiro creates plant-based crayons made from vegetables and rice

Mizuiro Inc., a Japanese company, founded by Naoko Kimura, a designer, created a crayon that is very safe for kids to use. They are not the traditional crayons as they were made from all-natural ingredients.

The coloring material that is mostly used for kids’ art projects is called the Oyasai Crayons, and they are also known as vegetable crayons. These are produced from food waste, so they are more sustainable and safer to use compared to the pigmented wax version that everyone is familiar with.

The introduction of eco-friendly crayons

The Crayon Collection project that was set up to make sure that all the children around the world would have access to crayons and develop their creativity stated that every year, around 150 million crayons are disposed of in the United States alone.

Environmental Leader noted that most of the crayons are not eco-friendly as well, and unfortunately, these are the types that are being sold in the market. These crayons are made of paraffin wax, where petroleum is one of its main components. This is a toxic chemical and obviously not safe for children, especially if they are accidentally swallowed.

What’s more, if these types of crayons are not recycled, they always end up in landfills and never decompose, so they remain as waste. Now, the Oyasai Crayons were introduced, and apart from the appearance, this is nothing like the traditional crayons.

How the plant-based “vegetable” crayons are made

These are made from rice and vegetables, so they are 100% all-natural. The rice bran oil and the wax from the rice bran are the main ingredients. The rice oil and wax are said to be byproducts of the rice polishing process, so the crayons are basically made from waste.

The pigments are from recycled materials as well, and leaves of vegetables are used for this. The discarded or rejected vegetables are collected during harvest periods and processed to create the color pigments in the plant-based crayons.

Since the crayons are made from vegetables, each color is given a name of the vegetable where it was actually made from, such as Japanese yam, corn, carrot, green onion, burdock, long potato, apple, purple potato, takesumi (a bamboo charcoal) and cassis.

As per Inhabitat, these pigments are the same ones that are used as ingredients in food. While this is not edible, it is surely all-natural, so parents can allow their kids to use crayons without any worries.
