Building a greenfield industrial waste processing facility is rarely a clean handoff from design to operation. Post-pandemic logistics introduced an additional layer of complexity. Equipment availability forced the team into a “design-as-you-build” paradigm, with equipment arriving in unpredictable phases. Engineering had to evolve alongside construction as schedules and priorities shifted. Operators worked closely with development and design teams to enhance functionality while learning the system in real-time. At the same time, management coordinated with regulators to ensure full compliance.
In this environment, it is not enough to build an automation solution “as specified”. Rather, it is imperative that through extensive collaboration between all the disciplines we build an intuitive, robust, adaptable and scalable system which will sustain the evolving operations from startup.
For this facility, those realities drove the need for an industrial automation and controls solution that could safely and reliably coordinate multiple complex waste streams while meeting stringent environmental compliance and regulatory reporting expectations.
Executive leadership prioritized multidisciplinary team collaboration to develop a solution that reduced operational risk, accelerated commissioning, and delivered audit ready data transparency across both continuous and batch-like processes. GPA was engaged to design and implement the automation and controls foundation needed to move confidently from construction through startup and into stable, long term operations.
Customer Challenge
Project leadership faced a convergence of strategic, operational, and regulatory challenges:
Greenfield Automation Delivery: End-to-end design and implementation of a 5,000+ I/O automation system, incorporating distributed control architecture, isolated automation islands, and high-availability operational technology.
Regulatory accountability: Automation decisions demanded first-time correctness, requiring compliance controls to be embedded within control logic to reduce operational exposure and ensure regulatory adherence.
Mixed continuous and batch processing complexity: Executive stakeholders required consistent, defensible data across liquid and solid waste streams operating on different time bases within a single control architecture.
Concurrent startup and evolving design: Shifting upstream documentation necessitated an agile, standards, driven automation strategy to protect schedule integrity and long-term system reliability.
Cross-system integration gaps: Subsystems were independently engineered as a self-contained automation solution, optimized for its own functionality, communication standards, and assumptions. When combined into a unified control system, these differences created significant challenges in interoperability, coordination, and overall system reliability.
GPA's Solution
GPA delivered a scalable industrial automation strategy aligned with executive priorities for reliability, compliance, and long-term value:
Unified resilient controls architecture: A high availability O.T network architecture with self-diagnostic capabilities was delivered. Adhering to the Purdue Model, the tiered network provided connectivity to over a dozen controllers, 10 local visualization units, 5000 I/O, and dozens of smart devices such VFD’s, analyzers, watchdogs etc.
Embedded environmental compliance logic: Specialized libraries were developed to comply with the unique process of regulatory compliance requirements. These libraries broke the waste information into its component parts performing and recording rolling averages at different intervals from one minute to 12 hours of each component as well as combinations of components.
Purpose built visualization solutions: A hybrid HMI architecture with a distributed HMI and visualization portal for all standalone specialty process areas was developed, emphasizing clear operator workflows, alarm rationalization, and operational resilience. Alarm design incorporated explicit indication of drive faults, permissive, and interlocks so operators could quickly distinguish process conditions from equipment availability issues.
Historian and data governance alignment: Controls, HMI, and historian layers were aligned to support executive visibility, audit readiness, and defensible long-term data retention.
Verification ready system design: Structured verification and validation methodologies were incorporated to support third party review, reduce compliance risk, and simplify future system modifications.
Remote startup and optimization support: GPA provides sustained remote automation support to accelerate commissioning, enable controlled system changes, and support operational continuity.
Project Scope
The automation scope delivered by GPA addressed both operational execution and decision‑maker priorities:
Enterprise grade controls architecture for mixed continuous and batch ‑waste processing‑ operations.
Development of the main distributed control system using FactoryTalk and ControlLogix platforms, with the capability to process 17 streams of waste concurrently.
Integration of vendor packages for the subsystems including PLC programming, HMI integration and communication interface setups.
Development of logic and graphic libraries for specialized process operations.
Integration with enterprise system that provided batch-like information on the chemical components of material in each stream.
Development of an inventory system for liquid streams with automatic transfers from trucks to tank farm to the streams.
Safe and reliable integration with CEMS, and BMS Regulatory systems.
Historian alignment to support regulatory averaging, traceability, and executive reporting.
Third party ‑ ready verification and testing documentation for regulatory compliance.
Multi‑phase remote startup, commissioning, and operational improvement support.
Redundancy and High Availability self-diagnosing systems.
OT infrastructure, networking, and connectivity tooling are intentionally excluded from this edition and will be addressed separately in Edition 2: End-to-End OT Delivery for a Greenfield Waste Processing Facility.
Results & Impact
The automation program delivered measurable value aligned with executive performance objectives:
Improved commissioning efficiency: Standardized automation and remote startup support reduced schedule risk and enabled controlled system deployment.
Operational consistency and risk reduction: Unified PLC, HMI, and alarm standards improved operator response, reduced ambiguity, and enhanced system resilience.
Regulatory confidence: Embedded compliance logic and verification artifacts provide a defensible foundation for audits, inspections, and regulatory reviews.
Scalable, future ready platform: The controls architecture supports expansion, innovation, and additional equipment integration without fundamental redesign.
Conclusion
This case study demonstrates GPA’s ability to deliver end-to-end industrial automation solutions for complex, regulated greenfield facilities. By aligning controls architecture, compliance logic, and startup execution with executive priorities, GPA provided a scalable automation foundation that supports safe operations, predictable commissioning outcomes, and long term regulatory confidence. The resulting platform empowers leadership with operational transparency today while enabling controlled growth and optimization in the future, with OT and infrastructure enhancements documented in a subsequent edition.
