Cardiff EfW

Cardiff Timelapse

Trident Park Energy Recovery Facility in Cardiff is now only a few months away from completion.

Once fully operational the facility will be handling 350,000 tonnes of residual waste, or post-recycling waste, per year, generating 28MW of electricity - enough to power around 50,000 households.  172,000 tonnes of that waste will be coming from five Councils that make up the Prosiect Gwyrdd partnership: Cardiff, Newport, Monmouthshire, Vale of Glamorgan and Caerphilly. 

LATEST UPDATE FROM SITE - 30 September 2014 @ 1445

The facility is currently in the hot commissioning phase, whereby heat is being introduced to the plant and all the systems and elements involved are tested and prepared for normal operations.

Hot commissioning is progressing well, with refractory dry out and boiler flushing completed and bag filter installation complete on Line 1 and due for completion on Line 2 on 30 September.

With affect from 30/9/14, we are scheduled to start raising low pressure steam in the boiler and conducting early low pressure steam blows, in preparation for full steam blowing next week.

From 3pm onwards on 30 September,  you may notice some steam venting from the roof of the building and, from a temporary silencer sited at ground level, some associated noise.

This procedure will involve firing and running the boilers using low sulphur diesel (<0.1% sulphur content) in accordance with the Permit.  This procedure may create a darkish plume of smoke from the stack, which is part of the commissioning process only and will not form part of normal operations.

The first delivery of waste has arrived on site and the first burning of waste is scheduled for Thursday 2 October.

Full high pressure steam blowing is currently scheduled for w/c 6 October.  This process involves high pressure steam running through the pipes to ensure they are clean and clear following the construction process.  Steam blowing will produce a visible plume of steam and can be a noisy process consisting of a loud rumbling noise.   The full steam blowing process will involve a single blow each day (including the weekend) lasting for approximately 15 minutes, and will continue for a period of around 10 days.

Steam blowing is a standard and safe process that is part of the commissioning process only.   Exact dates and timing of the full steam blowing process will be published on this site as soon as they are confirmed.

Should anyone have any concerns about the facility or operations at the site, please contact: 07717 873063
