50. ‘Mylo’ is an un-leather fabric and a very sustainable product. It is made from which of the following organic material?
[A] Mushroom
[B] Bamboo
[C] Eucalyptus
[D] Coconut
Show Answer
Correct Answer: A [Mushroom]
Notes:
Mylo is a leather-like material made from mycelium, the underground root structure of mushrooms. Mylo is a sustainable alternative to leather because it can be grown without polluting substances. It is also more sustainable than synthetic leathers, which are usually made from petroleum-derived inputs.
Mylo is grown in a controlled indoor environment. The growing process is designed to be low impact and takes less than two weeks. It emits fewer greenhouse gases and uses less water and resources than animal-based leather.
Mylo is 80% bio-based and is completely biodegradable and compostable. However, when extra durability is needed, the mushroom leather is reinforced with polyurethane, which decreases its biodegradability.
