A quiet competition is unfolding in the upstream textile sector: trees versus wheat straw. According to a new study led by Canopy, wheat straw—an agricultural waste—can fully replace wood pulp in producing viscose and lyocell fibers under laboratory conditions. This could disrupt a dissolving pulp market worth tens of millions of tons annually, introducing a cheaper and more abundant alternative.
Raw Material Cost and Supply Chain Disruption
Currently, wood pulp accounts for 40% to 60% of the raw material cost for viscose and lyocell. China, the world’s largest viscose producer, consumes about 7 million tons of dissolving pulp annually, with nearly 70% imported from Brazil, Canada, and Indonesia. If wheat straw fiber achieves industrial-scale production, its raw material cost could be 30% to 50% lower than wood pulp. China produces over 200 million tons of wheat straw each year, much of which is burned or left unused.
For man-made fiber mills, this could significantly expand procurement bargaining power. However, the key question is whether the pulping process for wheat straw can maintain viscose’s strength, dye uniformity, and hand feel while keeping production costs below those of wood pulp systems. Currently, Canopy’s research remains at lab scale, with no data from commercial-scale lines.
Regional Industrial Clusters and New Material Fit
China’s textile industrial clusters will see localized adjustments if wheat straw fiber is adopted. Key viscose-producing regions like Xinjiang, Shandong, and Jiangsu are also major wheat-growing areas. Xinjiang has about 1.7 million hectares of wheat, Shandong 6 million hectares, and Jiangsu 3.5 million hectares—short collection radii and low transport costs.
In contrast, coastal viscose mills in Zhejiang and Fujian, which rely on imported wood pulp, may face logistical disadvantages in switching to wheat straw. However, if the dry or wet spinning processes for wheat straw are compatible with existing equipment, mill retrofitting costs will be minimal. Major lyocell producers like Lenzing and Sateri have begun exploring non-wood fiber sources but have not disclosed specific investment plans.
The Real Cost of Sustainability
The environmental benefits of wheat straw fiber are clear: reduced deforestation, utilization of agricultural waste, and lower carbon emissions. But the industry must confront hidden costs. Wheat straw’s cellulose content is only 35% to 45%, compared to 50% to 60% in wood, requiring more raw material per unit of output. Additionally, higher silica content in wheat straw increases chemical consumption and equipment wear during pulping.
For buyers, if wheat-straw-based viscose or lyocell is only 5% to 10% cheaper than wood-based alternatives, the risk of switching may outweigh the reward in a supply chain that prioritizes stability. Fast-fashion giants like H&M and Zara have committed to 100% sustainable fibers by 2030, but wheat straw fiber must first pass third-party certifications such as Higg Index or FSC to enter their procurement lists.
