- The new Grangemouth biorefinery will be ten times larger than Celtic Renewables' current plant.
- Allen Associates will conduct a seven-month FEED study to refine design and cost estimates.
- The FEED study aims for a cost estimate accuracy of +/-10% and will outline the project execution plan.
- The biorefinery will support the transition to a green economy, creating high-value jobs.

Project Overview
Celtic Renewables is advancing plans for a large-scale biorefinery in Grangemouth, appointing Allen Associates to finalize the facility's design. The new plant will be ten times the size of the current demonstrator plant.
FEED Study
Allen Associates, based in Stirling, will conduct a seven-month Front-End Engineering Design (FEED) study. This study will refine the design and improve cost estimate accuracy to within +/-10%, while also establishing the project schedule and execution plan.
Industry Expertise
Allen Associates has extensive experience in the Scotch Whisky industry, which uses similar processes and technologies to those required for the biorefinery. This expertise will be leveraged to ensure successful project delivery.
Economic Impact
The new facility is part of a broader strategy to transition Grangemouth from its petrochemical heritage to a hub for Scotland's green economy, creating new high-value jobs in the process.
