Celtic Renewables awards Grangemouth biorefinery expansion FEED study

November 25, 2025 |

In the UK, Celtic Renewables is moving forward with plans to build a new industrial-scale green chemical production plant in Grangemouth. It has appointed engineering design consultancy Allen Associates, part of the Forsyths Group of companies, to undertake extensive work to finalise the design of the proposed new facility.

Stirling-based Allen Associates will carry out the Front-End Engineering Design (FEED) study based upon the design work completed by Celtic’s engineering team for the new commercial scale biorefinery that the company intends to build in Grangemouth. The capacity of the new facility will be ten times that of the company’s current demonstrator plant.

The seven-month study will further develop Celtic’s existing plans for the proposed facility. It will provide an improved cost estimate accuracy (+/-10%), secure the basis for the overall project schedule, and set out the project execution plan for the detailed design and construction phases. The details from the FEED will also provide verification of the associated business model, including projected revenues.
