Nanollose's origins are in a co-founder noticing a leathery substance in a batch of wine that went bad.

15 years later, the company says it is close to selling the first commercial garment out of "microbial cellulose". Its lyocell rayon fibres come from fermented food waste (currently the focus is coconut water by-products) instead of wood pulp, and it is in partnership with a global rayon leader to industrialise this "tree-free" substitute.

It says the lyocell is stronger than tree-derived rayon, needs less water and chemical additives in processing, and doesn't contribute to deforestation.
