Could Mushrooms be the Future of Plastic?
A lot of plastic foam is used to make packaging containers.
Unfortunately, the containers are used only for a few weeks to protect your brand-new computer or TV on its journey to your house, and then they end up in landfills.
Eben Bayer, an eco-friendly product designer, recognized that plastic foam has a negative impact on the environment.
He wanted to remove the need for it.
So, after years of experimenting, he created a 100% biodegradable packaging material.
The main ingredient of the packaging material is mushrooms.
Cheap, useless agricultural waste, like the husks of rice and wheat grain, is also needed to make mushroom packaging.
After the waste is cleaned, it is mixed with mycelium, a material that can be found at the root of mushrooms.
The mycelium holds the agricultural waste together and then the mixture is put into a mold.
With the mixture growing in the mold, the mushroom packaging takes the shape of the mold.
After a few days, the mixture is removed from the mold and it is dried to prevent any additional growth of the mycelium.
Finally, a 100% biodegradable package is ready for use.
Eben Bayer hopes that this mushroom packaging will replace plastic foam.
He says, “What I want to guarantee is that in 10,000 years, our descendants, our children’s children, will be living happily and in harmony with a healthy Earth.”
