A trusted process for successful plant modernization

ANDRITZ implements a proven, reliable, and transparent process to smoothly and successfully modernize your plant – on time, and on budget.

Step 1

Feasibility and concept definition

The first stage assesses plant performance, asset condition and compliance to define a modernization concept and go/no-go decision.

Step 2

Process design and specifications

Performance gaps are identified, and capacity, quality, and efficiency targets defined, with required utility, automation, and control upgrades.

Step 3

Engineering and layout

The upgrade is translated into a retrofit design, covering layouts, equipment selection, and integration, with shutdown planning to ensure efficient execution.

Step 4

Procurement and contracting

Sourcing of upgrade components and a phased execution strategy is defined. Budget and schedule are then finalised for clear alignment.

Step 5

Construction and installation

Modernization is executed through retrofit activities, including equipment and automation upgrades, minimizing operational impact.

Step 6

Commissioning and start-up

Upgraded systems are commissioned and tested, with operator training to ensure stable performance and improved operation.

Step 7

Optimization and handover

Finally, upgraded processes are fine-tuned to maximize efficiency and reliability. The plant is handed over as a future-ready operation.

Frequently asked questions

Modernization is planned around your production reality. We phase upgrades and align work with planned stops to avoid unnecessary full-plant shutdowns

We start by identifying where your plant is losing value — bottlenecks, energy losses, quality variation, waste, maintenance pressure, and manual dependency. Then we prioritize upgrades based on business impact: cost per ton, uptime, energy savings, product consistency, and ROI — so you invest where it matters most

Automation improves consistency and reduces manual dependency, while digital tools give real-time visibility and control — helping your team improve uptime, quality, and decision-making

We treat modernization as a controlled journey. Upgrades, retrofits and automation are introduced step by step so you continue producing while performance improves

We define expected improvements upfront — capacity, efficiency, energy savings, reduced downtime, and operating cost impact — so you have a clear business case performance audit, energy benchmarks, ROI models, and ranked upgrade options before implementation

We start with a performance assessment to identify the real constraint — process, equipment, or controls — and recommend the option that delivers the strongest business case

By targeting energy losses, waste, and process inefficiencies, modernization helps reduce resource consumption while improving overall plant performance
