Integrated C4 Value Chains and Green Procurement Standards Are Reshaping the Maleic Anhydride Downstream Market

BEIJING / SHANDONG, October 12, 2026 – The global maleic anhydride (MA) industry is moving beyond its traditional role as a merchant intermediate. Downstream value chains are extending toward biodegradable polymers, n-butane-based integrated projects are becoming the dominant production model, and carbon-footprint verification is emerging as a procurement entry criterion. For producers such as Binzhou Dayou New Energy Development Co., Ltd., these shifts are redefining what it means to be a reliable partner along the C4 chain.

The Downstream Chain Extends Toward Biodegradable Derivatives

MA is no longer consumed mainly by unsaturated polyester resins alone. Through hydrogenation, MA is converted into 1,4-butanediol (BDO), tetrahydrofuran and succinic acid, and further into biodegradable materials such as PBS and PBAT. Industry data suggest that BDO demand for MA reached about 790,000 tonnes in 2025 and is projected to exceed 850,000 tonnes in 2026, making the BDO chain the fastest-growing engine of MA demand. In China, the succinic acid chain features diversified upstream feedstocks, coexisting chemical and bio-based routes, and a downstream structure led by biodegradable plastics — a structure that gives MA a strategic position as the pivotal intermediate of the C4 platform.

n-Butane Integrated Projects Become the Mainstream Model

The n-butane oxidation route now accounts for more than 90 percent of global capacity, favored for its higher feedstock conversion, lower energy intensity and cleaner environmental profile compared with legacy benzene-based technology. New-generation projects apply vanadium-phosphorus-oxide catalysts and recycle by-product steam into surrounding plants, while converting MA in situ into BDO, succinic acid and PBS on the same site. This “C4–MA–BDO–succinic acid–PBS” integration model enables deep processing of intermediates and maximizes the value of the whole chain, and it is rapidly becoming the benchmark for capacity addition.

Carbon Footprint and Green Supply Chains Become Procurement Gateways

Sustainability is moving from a differentiating factor to a precondition in purchasing decisions. Downstream converters increasingly require MA with tight acid-value stability, low peroxide content and high thermal stability, supported by real-time quality data sharing. In the lubricant additives segment, customers typically demand benzene residues below 10 ppm and sulfur below 5 ppm, together with full life-cycle carbon-footprint reports; several international majors have incorporated suppliers into Scope 3 reduction programs targeting a 20 percent drop in carbon intensity of MA procurement by 2028. Producers that have secured environmental product declarations and entered green supply-chain lists are gaining priority status among global buyers.

Dayou’s Response: Consistency and Compliance Along the C4 Chain

Binzhou Dayou New Energy Development Co., Ltd. operates a 60,000-tonne-per-year MA plant based on the n-butane oxidation route, combining stable batch-to-batch quality with internationally recognized certification, including ISO, SGS and FAMI-QS. With exports to more than 30 countries and regions, Dayou positions its products to serve downstream customers across BDO, succinic acid and biodegradable polymer projects, supporting the industry’s transition toward integrated and low-carbon value chains. As green procurement standards continue to tighten, the company will keep strengthening quality consistency, process reliability and environmental compliance — the foundations that connect MA producers with the next generation of downstream value creation.
