Contact HiSiaddi customer service for more customized service inquiries.
Client: EcoMatter AG (Switzerland), a top-tier European bio-based material solution provider. It serves high-end degradable plastic, eco-coating and pharmaceutical intermediate brands across Switzerland, Germany and Austria, with a core positioning of "zero-carbon bio-based raw materials". The company complies with EU REACH, CBAM (Carbon Border Adjustment Mechanism), German DIN standards and Swiss eco-label requirements, imposing extremely strict standards on raw material bio-based content, purity, carbon footprint and customized indicators, and rejects conventional industrial-grade products.
In early 2026, the client launched a customization project for bio-based succinic acid dedicated to high-end PBS (polybutylene succinate), with core requirements as follows:
· Purity ≥99.95% (conventional industrial grade only reaches 99.5%); 100% bio-based content via fermentation (no petrochemical blending)
· Ultra-low ash content (≤0.01%), low metallic impurities (lead/arsenic <0.1ppm), low volatile matter
· Carbon footprint ≤0.8kgCO₂e/kg (EU CBAM low-carbon threshold)
· Custom particle size (200–300 mesh), customized packaging (25kg sterile aluminum foil bags), full batch traceability
· 5-ton trial production batch, followed by annual procurement of 50–80 tons; full delivery within 30 days with complete EU compliance documentation
Client Pain Points: After contacting 3 domestic manufacturers, the client encountered insufficient customization capacity, substandard technical parameters, long delivery cycles, and missing carbon footprint and bio-based certifications. Most manufacturers stated they could not simultaneously meet the standards of "high purity + 100% bio-based content + low carbon footprint". Additionally, small-batch customization entailed high costs and production scheduling difficulties, stalling the client’s project. The client entrusted HiSiaddi to fully resolve end-to-end customization and implementation challenges.
Conventional bio-based succinic acid is produced via fermentation plus crude purification, yielding only 99.5% purity with excessive ash and metallic impurities. Such materials are unsuitable for high-end PBS polymerization, as they easily cause catalyst poisoning and degrade the final product’s biodegradability. 100% bio-based production relies on pure sugarcane/corn starch fermentation without petrochemical additives. However, achieving high purity requires multi-stage crystallization and nanofiltration membrane treatment, equipment unavailable at most manufacturers, which limits purity below 99.9%. Carbon footprint control poses another challenge: most domestic manufacturers lack full-lifecycle carbon accounting systems. High energy consumption during fermentation, purification and drying results in a typical carbon footprint of 1.2–1.5kgCO₂e/kg, far exceeding the client’s 0.8kg threshold.
The client required ultra-fine powder of 200–300 mesh (conventional products are only 80–120 mesh), which demands air jet milling and classification equipment unavailable at most factories. Sterile aluminum foil bag packaging (to resist moisture absorption and contamination) requires production in a dust-free workshop, incurring high small-batch customization costs and low production scheduling priority. Full batch traceability requires a digital system covering fermentation strains, raw material batches, production parameters and test data, a system absent from most manufacturers.
The client demanded EU REACH registration, DIN SPEC 91236 bio-based content certification, ISO 14064 carbon footprint verification and Swiss eco-label recognition. Most domestic manufacturers only hold REACH pre-registration rather than full formal registration. Their bio-based and carbon footprint reports lack endorsement from EU-recognized third-party bodies such as TÜV Rheinland Germany, failing client audits.
The 5-ton small-batch order required independent production scheduling, dedicated production lines and exclusive testing, reducing factory capacity utilization and pushing costs up by over 30%, exceeding the client’s budget. Standard lead times range from 45 to 60 days, while the client required delivery within 30 days, creating tight timelines for coordinated production and logistics.
Against four core criteria — 100% bio-based content, purity ≥99.95%, low carbon footprint and customization capability — HiSiaddi screened 5 leading bio-based succinic acid manufacturers and finalized a joint customization partnership between Shandong Landian Bio (leading fermentation technology) and Shandong Huaheng Bio (specialized precision purification). Landian Bio handles pure sugarcane fermentation to guarantee 100% bio-based content, while Huaheng Bio delivers multi-stage crystallization, nanofiltration membrane treatment and ultra-fine milling to achieve high purity and customized particle size, leveraging complementary strengths to resolve technical pain points.
Fermentation stage: Proprietary high-sugar tolerant strains from Landian Bio are adopted for sugarcane juice fermentation with zero petrochemical additives, delivering 100% bio-based content. Purification stage: Three rounds of low-temperature crystallization plus two-stage nanofiltration membrane deep impurity removal eliminate ash, heavy metals and volatile matter. Final purity stabilizes at ≥99.97%, ash content ≤0.008%, and metallic impurities <0.05ppm, exceeding client requirements.
Energy side: 100% green electricity (solar + wind power) is deployed for production to cut carbon emissions from energy use. Process side: Optimized fermentation and drying parameters reduce energy consumption, lowering the carbon footprint to 0.72kgCO₂e/kg, below the client’s 0.8kg threshold. Certification side: TÜV Rheinland Germany conducts full-lifecycle carbon accounting and issues an authoritative ISO 14064 verification report.
Specialized air jet milling and classification lines at Huaheng Bio precisely control particle size within 220–280 mesh (within the client’s target range), delivering free-flowing powder free of agglomeration ideal for PBS polymerization.
Dedicated production line access: HiSiaddi coordinated manufacturers to launch a green channel for small-batch customization. The 5-ton order was produced on an independent line with a dedicated technical team for full-process monitoring, avoiding cross-contamination with standard orders and completing production within 30 days. Dust-free packaging: 25kg food-grade sterile aluminum foil bags (inner PE layer, outer aluminum foil barrier to prevent moisture absorption and oxidation) are packed in a Class 10,000 dust-free workshop, with a unique traceability QR code attached to each bag. Full-lifecycle traceability: A digital traceability system is deployed, enabling full query of fermentation strain serial numbers, sugarcane raw material origin/batches, fermentation temperature/duration, purification parameters, test reports and production personnel for every batch, complying with EU traceability standards for food-grade raw materials.
HiSiaddi compiled a full set of EU compliance documents, dual-certified by TÜV Rheinland Germany and SGS Switzerland, ensuring seamless customs clearance and market launch for the client: Product qualifications: Full EU REACH registration for 100% bio-based succinic acid, DIN SPEC 91236 100% bio-based content certification, ISO 14064 carbon footprint report, ISO 9001/14001 certifications.

Customs clearance documents: Certificate of origin, sanitary certificate, free sales certificate, carbon footprint statement, bio-based statement, compliant with Swiss customs and EU CBAM declaration requirements.
Cost control: HiSiaddi integrated production capacity of Landian and Huaheng, jointly purchasing raw materials and sharing production lines to reduce customization costs. Final pricing only rose by 12%, far lower than the standalone factory premium of over 30%, aligning with the client’s budget. Delivery acceleration: 22 days for production + 3 days for testing + 2 days for packaging + 3 days for logistics, totaling a 29-day turnaround with delivery one day ahead of schedule. Cold-chain China-Europe Railway Express transport with constant temperature control (15–25°C) prevents moisture absorption and deterioration, with direct delivery to Zurich, Switzerland for efficient customs clearance.
The client’s laboratory conducted full-parameter testing on customized samples with results as follows:
· Purity: 99.97%; Bio-based content: 100%
· Ash content: 0.007%; Metallic impurities: Not detected
· Carbon footprint: 0.72kgCO₂e/kg; Particle size: 250 mesh Conclusion: All indicators meet standards, with several exceeding expectations, suitable for high-end PBS polymerization.
The client submitted the full bilingual compliance package compiled by HiSiaddi to Swiss customs, TÜV Rheinland Germany and EU CBAM pre-audit, passing in one review. The materials were confirmed compliant with EU and Swiss market access standards, qualifying the client for low-carbon tariff reductions under CBAM.
In April 2026, the 5-ton customized bio-based succinic acid was shipped on schedule via cold-chain China-Europe Railway Express to the client’s Swiss warehouse, with no moisture absorption, deterioration or damaged packaging. All client sampling tests passed. The material was deployed for high-end PBS production, delivering stable polymerization and compliant biodegradability, enabling the client to launch products into Switzerland’s high-end degradable plastics market.
The client highly recognized HiSiaddi’s strengths in technical customization, compliance implementation and delivery assurance, appointing HiSiaddi as its exclusive China-based customization partner for bio-based raw materials. In May 2026, the client placed an annual framework order for an additional 50 tons, and entrusted HiSiaddi with developing customized high-end products including bio-based adipic acid and bio-based 1,4-butanediol for European market expansion.
Overseas mid-to-high-end clients sourcing customized bio-based succinic acid face core pain points: stringent technical parameters, insufficient customization flexibility, high EU compliance barriers and difficulties delivering small batches on schedule. Most domestic manufacturers cannot simultaneously satisfy six core demands: high purity, 100% bio-based content, low carbon footprint, customization, short lead times and controlled costs.
