Biodegradable hemp fiber masks

Currently, it is estimated that 129 billion disposable masks are used and thrown away every month in the world, representing serious public health and environmental problem. A French startup called Geochanvre presents a biodegradable alternative.

After the coronavirus erupted in the world, this company saw that its compostable material - used for planting and packaging - could also be used as a safe filter for masks, responding to the health emergency with its vegetable felt.

Their mask has a filtration efficiency level of 89% at 3 ?m particles and an air permeability of 459 litres / m2 / sec. They cost less than one euro each, they can be ordered in packs of 50, 250 or 400 masks, as well as personalised with different logos. The box of 50 sells for only 34.29 euros.

Considering that disposables that end up in the ocean will take up to 450 years to decompose, according to the Waste Free Oceans campaign group, it is worth betting on biodegradable alternatives made from hemp or wood fibres.
