Case study – development and custom manufacturing of specialty ingredients compound for a TOP5 global chemical company

In the specialty chemicals industry, accelerating innovation while ensuring safety, quality, and regulatory compliance is a critical challenge. This white paper demonstrates how SEQENS, a global CDMO and industrial partner, successfully transforms complex chemical processes into robust, scalable, and sustainable industrial manufacturing. Through a real case study with a leading global chemical company, it highlights SEQENS’ ability to combine advanced R&D capabilities, engineering expertise, and strong regulatory management to deliver efficient time‑to‑market and long‑term industrial performance.

Project Development Phase

During the development phase, SEQENS deploys a structured approach to chemical process development, combining scientific excellence, raw‑material sourcing, risk assessment, and pilot‑scale validation. Over six months, multidisciplinary teams optimize the synthesis route using Design of Experiments and advanced analytical technologies. Early sourcing ensures cost competitiveness and supply chain reliability, while regulatory assessments (toxicology, REACH, IP) secure compliance. A three‑month pilot stage validates process robustness at ton scale, qualifies suppliers, optimizes operating conditions, and delivers the first industrial‑representative quantities. This phase lays the foundation for a predictable and scalable industrial transfer.

Industrial Implementation and Site Adaptation

To transition from pilot to commercial production, SEQENS adapts and upgrades the Couterne site with tailored industrial capabilities. These include dedicated storage for sensitive materials, enhanced reactors with improved exothermic control, automated powder‑handling systems, and customized gas‑scrubbing equipment. Analytical capabilities are reinforced to ensure precise in‑process control, while utilities such as steam, nitrogen, and electricity are secured to support industrial ramp‑up. These targeted upgrades enable SEQENS to deliver safe, efficient, and compliant large‑scale manufacturing aligned with the customer’s process requirements.

Timeline and Project Management

The industrial implementation relies on strong project governance over an 18‑month period (). This includes preliminary CAPEX evaluation, heat and mass balance modeling (ASPEN), equipment specification, and coordination with engineering firms during construction. The detailed design and build phase ensure cost control and planning accuracy. Final qualification activities include equipment commissioning, operator training, and a technical validation batch to confirm alignment between the new installations and product specifications. This structured roadmap ensures a seamless scale‑up to commercial manufacturing.

Regulatory Compliance and Quality Oversight

SEQENS manages extensive regulatory updates to ensure full compliance during industrialization. This includes ICPE and SEVESO documentation, HAZOP analyses, ATEX zoning of new areas, creation or update of Safety Data Sheets (CLP), REACH registration activities, and support for customer regulatory dossiers when required. Environmental monitoring across air, water, and soil ensures the new installation meets all safety and environmental protection requirements. This comprehensive regulatory framework guarantees safe, compliant, and responsible chemical manufacturing.

Performance and Success

The industrial implementation delivers significant performance improvements. Process optimization and recycling loops reduce effluents and waste by a factor of three. A 20% reduction in carbon footprint is achieved compared with the initial technical package. Digitalization—through enhanced monitoring, automated controls, and data‑driven decision‑making—improves right‑first‑time performance by 20% and increases overall equipment effectiveness (OEE). These results demonstrate SEQENS’ ability to combine operational excellence with sustainability and innovation in specialty chemical manufacturing.

By integrating advanced R&D, tailored engineering solutions, rigorous regulatory oversight, and strong sustainability performance, SEQENS offers a powerful and reliable industrialization model for specialty chemical projects.
