In January 2025, research published in MDPI on bio-microcapsules of PBS and isocyanates highlighted their potential for sustainable, safer, and more efficient adhesives – demonstrating that PBS is finding new high-value application avenues beyond its established packaging and agricultural markets, expanding the commercial addressable market for Indian PBS manufacturers.
Manufacturing Process – Step by Step
The polybutylene succinate manufacturing process uses synthesis of succinic acid, polymerisation, blending and modifying, extrusion and moulding, and quality control as the primary production method. Below are the main stages involved in the PBS manufacturing process flow:
- Raw Material Receipt and Quality Testing: Succinic acid, butanediol, and catalysts are received, tested for purity, composition, and conformance to process specification, and cleared for production scheduling following quality verification.
- Succinic Acid Preparation: Succinic acid – which can be sourced from petrochemical routes or from bio-based fermentation of plant sugars – is prepared and characterised to the required purity and physical form specification for the polymerisation process. Bio-based succinic acid sourcing is preferred where sustainability certification is required for premium eco-label market access.
- Polymerisation – Polycondensation Reaction: Polymerisation reactors combine succinic acid and butanediol in the presence of catalysts under controlled temperature and vacuum conditions through a polycondensation reaction – initially forming low-molecular-weight oligomers through esterification, then building molecular weight through polycondensation under progressive vacuum to achieve the target intrinsic viscosity and mechanical property specifications for the designated PBS grade.
- Blending and Modifying: Blending equipment combines the base PBS polymer with permitted additives – including chain extenders, nucleating agents, stabilisers, and functional fillers – to modify specific mechanical, thermal, processing, and biodegradation rate properties for application-specific grades targeting packaging, agriculture, automotive, or medical end-uses.
- Extrusion and Pelletising: Extruders and pelletisers process the compounded PBS polymer melt through a die and cutting system to produce uniform cylindrical pellets of the specified dimension and bulk density – the standard commercial form in which PBS is supplied to downstream film converters, injection moulding processors, and compounders.
- Injection Moulding (where applicable): Injection moulding machines convert PBS pellets into finished moulded products – including food containers, agricultural plant pots, and consumer product parts – where the plant includes downstream conversion capability alongside polymer pellet production.
- Quality Inspection and Testing: Quality management systems subject finished PBS pellets and moulded products to comprehensive testing – including melt flow index, intrinsic viscosity, mechanical property testing (tensile strength, elongation at break, flexural modulus), thermal analysis, biodegradation rate testing, and compostability certification testing – with batch release conditional on all parameters meeting the applicable product specification acceptance criteria.
- Packaging and Dispatch: Finished PBS pellets are packaged in moisture-protected bulk bags or 25 kg bags depending on customer requirement, with product certification documentation including intrinsic viscosity, compostability certification, and bio-based carbon content where applicable, before dispatch to packaging film converters, agricultural product manufacturers, automotive component suppliers, medical product formulators, and consumer goods manufacturers.

Key Challenges to Consider
Succinic Acid Price Volatility as the Dominant Cost Variable. Succinic acid – accounting for 65–75% of total OpEx – is the primary cost driver and the most significant risk variable in PBS production economics. Succinic acid pricing is influenced by bio-based feedstock costs and petrochemical feedstock dynamics, and any meaningful price movement directly and materially compresses gross margins. Long-term supply contracts with qualified succinic acid producers and multi-supplier qualification are essential risk mitigation strategies.
Bio-Based Succinic Acid Supply Chain Development. For manufacturers targeting premium eco-label markets that require certified bio-based carbon content in finished PBS, sourcing succinic acid from bio-based fermentation routes – rather than petrochemical synthesis – adds supply chain complexity and potentially higher feedstock costs relative to petrochemical routes. Building reliable bio-based succinic acid supply chains requires early supplier qualification and long-term procurement commitments.
Compostability Certification Requirements for Premium Market Access. Accessing the premium pricing tier in food packaging and agricultural film markets requires internationally recognised compostability certification – including EN 13432 in Europe, ASTM D6400 in North America, and applicable Indian standards for domestic market claims. Obtaining and maintaining these certifications requires testing infrastructure, third-party certification body engagement, and ongoing documentation management that adds pre-market preparation time and compliance overhead.
Competition from Established Global and Emerging Asian Producers. The PBS market is served by established Asian producers including PTT MCC Biochem, Anhui Sealong, and multiple Chinese manufacturers with growing production capacities and competitive pricing. New Indian manufacturers must differentiate through product quality consistency, bio-based certification for premium eco-label segments, application-specific grade development, or cost competitiveness for domestic packaging and agricultural volume buyers who prefer local supply chain reliability over imported alternatives.
Utility Cost Management for Polycondensation Operations. Utility costs at 15–20% of total OpEx reflect the continuous energy requirements of polymerisation reactor operation, vacuum system management for polycondensation, and extrusion line heating. Managing electricity and steam costs through efficient process design and competitive tariff procurement is a material operational priority for protecting gross margins at the 30–40% level.
Skilled Workforce for Polymer Chemistry and Process Operations. Operating polymerisation reactors, extrusion systems, and polymer quality testing laboratories requires chemical engineers and polymer processing technologists with specialised knowledge of polycondensation chemistry, PBS rheology, and biodegradable polymer quality management. Sourcing and retaining qualified personnel for this technically demanding manufacturing category presents an ongoing challenge in India’s current specialty polymer talent market.
