The Growing Importance of Chemical Recycling in a Circular Economy
Across the world, nations are rethinking what “end-of-life” truly means for materials and how they move through the global economy. The shift toward responsible industrial growth, carbon reduction, and sustainable engineering is driving a new wave of innovation in recycling technologies. Chemical recycling plays a crucial role in this transformation, converting mixed, hard-to-recycle waste streams into valuable feedstocks, specialty chemicals, and renewable fuels.
This is where the technical expertise of Shiva Engineering Services (SES) comes in. As a trusted engineering consultancy for the global recycling industry, SES enables the transformation of environmental challenges into commercially viable opportunities through smart design and sustainable process engineering.
Building such plants requires the collaboration of multiple engineering disciplines, process and chemical engineers who define reaction routes and kinetics, piping and structural engineers who translate processes into buildable layouts, ensuring safety and compliance. SES’s integrated engineering delivery model brings all these competencies together under one framework, helping the recycling industry optimize operations while minimizing capital expenditure.
Engineering Challenges in Chemical Recycling Plants
Feedstock Variation
One of the primary engineering challenges in chemical recycling lies in feedstock variability. Different waste streams, even within the same material typ,e contain varying levels of impurities such as metals, organics, and other contaminants. For example, two batches of plastic waste can differ significantly in composition, impacting downstream reactions and yields.
With deep process understanding, SES engineers design systems that segregate and pre-treat feedstock before reactions begin, ensuring stable quality and improved process yield. Using advanced process simulation tools, SES models multiple feedstock compositions to optimize conversion efficiency, yield consistency, and energy balance, forming a reliable foundation for Front-End Engineering Design (FEED).
Process Optimization
Another key challenge is process optimization, since every recycling technology operates under unique parameters such as temperature profiles, catalysts, and residence times. As part of our engineering services for greenfield projects in the chemical industry, SES ensures new plants are designed with the right balance between heat integration, waste recovery, and flue gas treatment minimizing energy losses while maximizing output.
Emission and Compliance Management
Environmental performance is integral to plant design. SES incorporates scrubbers, condensers, and continuous emissions monitoring systems (CEMS) right from the conceptual stage, ensuring compliance with environmental regulations and supporting long-term operability with minimal environmental footprint.
End-to-End Engineering Solutions for Chemical Recycling Processes
Once the FEED package is approved, our engineering consultancy for the recycling industry advances into detailed engineering, covering process equipment, piping, civil and structural works, electrical distribution, automation, and instrumentation. This is the stage where 3D plant models, piping isometrics, and structural drawings are developed in parallel, ensuring every discipline works in sync. What makes the process efficient is the tight coordination between design, procurement, and construction teams. There’s a continuous loop of communication so that design intent translates to site execution.
On the procurement front, Our EPCM services manage vendor prequalification, technical bid analysis, contract negotiations, and expediting with a focus on schedule reliability. For long-lead items, SES’s procurement engineers maintain an updated database of qualified global and Indian suppliers, ensuring timely sourcing and preventing last-minute bottlenecks.
During construction, our management teams oversee civil, mechanical, and electrical execution, coordinate safety reviews, material tracking, and quality control in alignment with project timelines and regulatory standards. To help clients meet environmental compliance requirements, SES emphasizes sustainability across every stage, promoting the use of recyclable materials, energy-efficient systems, and on-site waste minimization. This same rigor extends to our pilot-to-commercial execution, where each process design is validated, scaled, and optimized for dependable performance in commercial production, enabling clients to transition confidently from concept to operation.
