South West Wales DATGLOI Powering Cleaner Rivers Project - Specialist Consultancy Services

Procurement reference

PROC/2627/090

Procurement description

Pembrokeshire County Council on behalf of the South West Wales Corporate Joint Committee is developing the South West Wales DATGLOI Powering Cleaner Rivers project to explore how catchment-scale anaerobic digestion can support Wales’s climate change and nature recovery targets by bringing together agricultural nutrient management, renewable energy generation, river restoration and circular economy innovation within a single integrated model.

The project will focus on the potential development of anaerobic digestion infrastructure at a pilot site at Cwm Gwyrdd Nantycaws; the emerging circular economy park in Carmarthenshire. The study will assess how agricultural slurry, and other organic waste streams could be collected, processed and converted into renewable energy, while also supporting improved nutrient management in sensitive river catchments.

It will investigate how anaerobic digestion could improve slurry management, generate low-carbon energy, recover nutrients for reuse and export out of the catchment, reduce reliance on imported fertilisers, and support wider catchment recovery objectives. The project will also explore opportunities to process digestate into higher-value products, including potential biochar applications, creating further opportunities for carbon sequestration and circular economy development.

Engagement process description

South West Wales Corporate Joint Committee undertook a period of market engagement prior to the announcement of the DATGLOI fund within the Anaerobic Digestion sector with projects funded by Welsh Government via Smart Living WSRID (Whole Systems Research and Innovation for Decarbonisation) and the SBRI Agri-Food Technology Challenge. Discussions were held with a small number of organisations possessing relevant technical knowledge, experience and expertise as the SWWCJC looked at opportunities for anaerobic digestion to tackle nutrient management challenges alongside energy generation.

The purpose of the engagement was to improve the organisation’s understanding of the market and inform the development of an appropriate regional strategy and identify opportunities for project development. Participation in the engagement did not confer any advantage, preference or commitment in relation to any future procurement opportunity. No supplier was selected, shortlisted or otherwise favoured as a result of the engagement.

The engagement demonstrated market interest future projects and identified a range of potential technical, operational and delivery approaches. This complemented wider stakeholder engagement undertaken at sector events.

The information obtained through the market engagement has been used solely to inform the Authority's understanding of the market and the development of its requirements. The engagement has not determined the final specification, procurement procedure, award criteria, contract structure or the selection of any future supplier.

Any future procurement will be conducted through a fair, open and competitive process. All interested and eligible organisations will have an equal opportunity to participate. Relevant non-confidential information and key findings arising from the preliminary market engagement will be made available through the procurement documentation where appropriate to ensure transparency and maintain a level playing field for all potential tenderers.
