Sustainability Procurement Expands Recycled Fiber Use
Brand owners increasingly specify recycled fiber duplex board previously limited to small premium pilot lines, applying surface-coating precision across an expanding list of mid-size regional converters as sustainability procurement standards increasingly make documented recycled-fiber content a measurable compliance attribute rather than a manageable material detail. This shift is creating substantial new demand beyond the category's traditional virgin-fiber base, giving formulation-capable mills a genuine growth avenue tied to procurement-driven adoption rather than pure standard-category volume growth. Mills with established converter relationships are capturing disproportionate share of this expanding demand across newly converted accounts worldwide. This dynamic also shapes the corrugated board market, valued by MMA at USD 38.0 billion in 2025 and expected to reach USD 58.5 billion by 2036.
