Site History

The existing landfill site (Phase 2) has been operational since 1997. Prior to that, Phase 1 which adjoins but is physically separate from Phase 2 was operated by the local authorities. Phase 1 is now under aftercare and restoration.

Design Principle

The site comprises five landfill cells, and each one has been designed on the basis of engineered containment. Ground and surface water is protected against contamination by the provision of a composite geomembrane / mineral liner placed on to a contoured landform.

Restoration

The landfill site will be restored progressively to agricultural land using a composite geomembrane / drainage layer with a further subsoil and topsoil capping layer which will have the dual effect of controlling leachate volumes and restoring the usefulness of the land for stock grazing.

Nantycaws Landfill Site

Nantycaws landfill site provides an option for the disposal of residual waste in Carmarthenshire and its immediate environs. CWM Environmental Ltd. fully understands and supports through ancillary activities the progressive statutory and regional initiatives to reduce, recycle, reuse and pre treat municipal, commercial and industrial wastes. However, it is envisaged that there will always remain a regional need to cater for the landfilling of this diminishing final fraction. The company objective is to ensure the provision of a professionally managed facility to cater for its customers needs.

Directions

The site is located approximately 8 km to the east of Carmarthen on the A48 and lies 1.5 km to the south-east of the small village of Nantycaws.

Site Licence

The site is licensed under:

The Pollution Prevention and Control (England and Wales) Regulations 2000
Landfill (England and Wales) Regulations 2002

Permit Number - CP3735PB

Site Inputs

The site is authorised to accept a maximum of 150,000 tonnes of non hazardous waste per annum. All vehicles depositing waste must report to the weighbridge in the first instance.

Environmental Controls

Landfill Gas
Buried biodegradable organic waste (such as food and paper) decomposes by anaerobic microbial action which produces landfill gas. The gas generated at the Nantycaws Site is drawn off and converted to energy. An active gas management system operates at the site. Landfill gas is passively vented to the surface through a series of gas vents and a perimeter gas collector and then pumped to an on site Waste to Energy Plant. The current system will be extended as the landfill continues to develop.

Leachate
During the operational life of the site the arising leachate is collected from the wastes by a series of gravity drains that transport the leachate to cell sumps. The leachate is then removed from the sumps to a holding lagoon prior to being tankered away for off site treatment / disposal.

Monitoring
The site maintains and implements an emissions monitoring programme which ensures that emissions are monitored from specified points, for parameters listed in and to the frequencies and methods described in the site ‘Permit’. All monitoring data is reported back to the Environment Agency.
