The global cellulosic fiber market is witnessing a new wave of capacity expansion. Grasim Industries, flagship company of the Aditya Birla Group, announced an investment of ₹3,094 crore (approximately $324 million) to build Phase II lyocell capacity of 110,000 TPA at its Harihar plant in Karnataka. The expansion will consist of two 55K TPA lines, each with a daily output of 150 tons. Once operational, Grasim's total lyocell capacity will surpass 200,000 TPA, placing it among the few global players capable of large-scale supply.
Strategic Logic Behind the Expansion
The timing of the project, scheduled for 2026, aligns with a surge in global demand for sustainable fibers. Lyocell, produced via a closed-loop process with over 99% solvent recovery, has become a priority in the ESG procurement lists of European and American brands. For the Aditya Birla Group, this move is not just about volume. With existing viscose and modal lines, the lyocell expansion completes a three-tier product matrix: viscose for cost-sensitive segments, modal for mid-range, and lyocell for high-end eco-friendly applications. This differentiation hedges price volatility across fiber types and strengthens bargaining power with large fabric buyers.
Impact on Global Fiber Supply
The capacity release will trigger three shifts. First, substitution pressure on viscose staple fiber will intensify. Currently priced at 60%-70% of lyocell, viscose's cost advantage may shrink to within 20% as lyocell scales, prompting mills to switch blends. Second, the cotton market faces indirect headwinds. With rising planting costs and climate disruptions in major cotton-producing countries, lyocell fills the gap when cotton prices are high. Global lyocell capacity is projected to exceed 600,000 tons by 2025 and approach 1 million tons by 2028, exerting long-term downward pressure on cotton prices. Third, polyester staple fiber will feel the pinch. Although polyester remains cheaper, concerns over microplastic pollution and fossil fuel dependency are pushing fast-fashion brands toward lyocell blends. Assuming a 50% export ratio, the new 110,000-ton capacity could release about 55,000 tons annually to Europe and China, directly challenging polyester's market share.
Responses Across the Textile Chain
For China's textile clusters, two implications stand out. First, the supply stability of imported lyocell improves, enabling fabric mills in Keqiao and Shengze to develop high-count, high-density lyocell fabrics or lyocell/cotton blends, raising export unit prices. Second, domestic lyocell producers must accelerate technology upgrades and cost control. China's current lyocell capacity is about 150,000 tons, but most lines are 10,000-20,000 tons per line, far smaller than Aditya Birla's 55,000-ton lines. The cost gap is significant. End-brand reactions are telling: H&M and Zara have raised lyocell's share in their 2026 sustainable fiber procurement targets from 5% to 12%. Fabric traders should lock in annual contracts with Grasim and other top suppliers early to avoid price spikes during the initial capacity release.
