Summary

An EfW facility based upon conventional combustion technology, located at Earls Gate Park, Grangemouth in Scotland. The facility is forecast to have a maximum capacity of 215,000 tonnes per annum (with a permit extension pending to take it to 274,000 tonnes), and will be a Combined Heat and Power facility, exporting 21.5 MW electricity and heat to the nearby chemical company CalaChem and to other adjacent industrial plants, with any excess power fed into the national grid. The cost of the project is circa £200m, which was provided by the investors Brockwell Energy, the Green Investment Group and Covanta.

In March 2022 EQT, the owner of Covanta (now branded Encyclis, bought the interests of the Green Investment Group in this and three other projects (Rookery Pit Energy Recovery Facility (Rookery South), Protos EFW, and Newhurst EFW) to leave Green Investment Group with no further interest in the projects.

The facility was developed by Brockwell Energy, and was originally planned to be operated by MES Environmental for a contract duration of 25 years. Subsequently Hitachi Zosen Inova were contracted to complete the construction of the plant and were awarded a 25 year contract to operate it.

The EfW will replace an existing gas-fired energy plant on the site.

The facility was expected to become operational by the end of 2021 but ran into delays through the construction subsidiary of CNIM responsible for delivery of EfW projects running into financial difficulties in January 2022. This is also impacted a second plant under construction at Lostock Sustainable Energy Plant.

The plant was reported as becoming operational in May 2025 on the Hitachi Zosen Inova LinkedIn page and on the company website as February 2024.

Technology

The moving-grate combustion technology was provided by CNIM.

Construction

CNIM was the original EPC contractor for this facility, with Clugston in charge of the civil engineering. Construction commenced in January 2019 and was scheduled to take 3 years, with commissioning ending and operations beginning in 2021. However, with CNIM falling into financial difficulty, and ultimate collapse, Hitachi Zosen Inova took over the completion of the construction and the O&M contract.

Waste Input

The facility will accept residual waste as feedstock.
