Sustainable Fashion: Do you want your clothes to shrink our forests?

Brands seeking to make more sustainable materials using less energy, water and biodegradable are ironically relying on fibres extracted from forest produce like wood pulp.  An estimated 300 million trees are cut down for these manmade cellulosic fibres every year, and there have been reports linking rampant deforestation with some of the world’s largest pulp and viscose producers

Do you know what you’re wearing? I don’t just mean if it’s a shirt or a jumper, or whether it’s designer or fast fashion. I’m talking about the fabric — and its source.

Cotton is fairly recognisable, and many know wool comes from sheep. But do you know that linen is made of the blue-flowered flax plant? That cashmere and mohair come from different breeds of goat, while angora comes from a type of rabbit? And polyester and polyamide are made out of oil?

Perhaps the least well-known origin story, and one of the most significant for the climate and biodiversity crises, is that fabrics such as viscose, lyocell and modal were once trees.

These materials, known collectively as man-made cellulosic fibers (MMCFs), are made of dissolved wood pulp and account for just over 6 percent of our clothing. Yet production is growing as brands seek more sustainable materials. These forest fibers tend to use less water and energy than other types of fabric. They also have the potential to be fully biodegradable (depending on which chemicals are used to treat and dye the fabric) and come from a renewable resource. So far, so good.
