Fairchild Media released an article explaining how, “Today, 6.4 percent of textiles are produced with wood-based feedstock, according to sustainability nonprofit Textile Exchange. With deforestation responsible for up to 10 percent of greenhouse gas emissions, pivoting to ‘forest-positive’ sourcing for man-made cellulosic fibers (MMCF) such as viscose, lyocell, modal and acetate, has never been more critical.”
It’s always been more than just chopping down and replanting trees, since trees and forests support a complex network of biodiversity and life.
Additionally, “The United Nations estimates that one-quarter of the world’s population, or 1.6 billion people, depend on forests for their subsistence needs, livelihoods and incomes.”
The proposed solution is man-made cellulosic fibers (MMCF), which are “regenerated fibers usually made from the dissolved wood pulp or ‘cellulose’ of trees. Viscose, lyocell, and modal are all kinds of manmade cellulosics. Because they’re plant-based, MMCFs are renewable, and so have the potential to be a climate-friendly material if the wood is sourced sustainably and the processing chemicals are handled properly,” according to Textile Exchange.
For apparel products in particular, this new type of material will disrupt the current fashion system, which is operating “in a linear manner of extracting virgin resources and disposing of clothing once it has reached its perceived end-of-life, generating a huge amount of waste,” according to Fashion For Good. “Textile-to-textile recycling holds significant potential to close the loop in MMCF — alleviating the strain on virgin resources (problem 1) and reducing the amount of used textiles going to landfill / incineration (problem 2).” Using cotton waste is also more efficient than virgin wood in terms of its yield, “given the purity of cellulose in cotton.”
For Julia Kozlik, textile program lead at the Programme for the Endorsement of Forest Certification (PEFC), this issue is at the forefront of her mind. Although all of this sounds promising, “Kozlik said that much of this is still new to many brands that might be just beginning to implement certain policies around MMCF sourcing. They might not be aware of what tools they can use to trace and verify materials once they leave the forest.” She also stated, “They might not even know that viscose comes from trees. But also there’s little visibility — we don’t really have enough verified statements, claims or anything about the origins of those fibers that consumers can see from their garments.”
According to Fairchild Media, the aim is to support retailers so they’ll begin:
- Understanding the sourcing landscape, which includes the location of forests and their specific social and environmental contexts.
- Establishing a sourcing policy that encompasses sustainable forest management standards.
According to Kozlik, “The market share of MMCFs verified by PEFC and the Forest Stewardship Council has been increasing from 55 percent to 60 percent in 2020 to 60 percent to 65 percent in 2021. But that leaves another 35 percent of the fibers with unknown sources.”
Ultimately, all of this bodes well as many fashion brands have also pledged to completely switch to deforestation-free leather by 2030.
Without any current loud opposition to this new MMCF system, there don’t appear to be any cons at the moment.
