A Belgian company grows mushrooms from coffee grounds. Coffee grounds are leftover coffee. You have them after you make coffee. They are usually waste.
The company gets 5.5 tons of coffee grounds from cafes every month. Workers mix the grounds with mushrooms spores. Then the mushrooms grow inside small bags.
Mushrooms need 15 days to grow. Workers then harvest the mushrooms. They empty the bags.
They use the material to make insulation tiles. Insulation tiles protect a place. By 2025, the company plans to make 13 tons of tiles every month. The plan is a good way to use less plastic.
