Burges Salmon advises on anaerobic digestion contract

Burges Salmon has advised Gwynedd Council on a pathfinding PPP contract with BiogenGreenfinch regarding an 11,000-tonne anaerobic digestion (AD) facility at a former landfill site at Llwyn Isaf in north-west Wales.

When operational, the plant will generate 3,500MWh per year of renewable electricity.

This project — Prosiect GwyriAD — is claimed to mark a major milestone in the Wales-wide procurement ‘hub’ initiative and, once operational, will provide a full-circle solution diverting all household food waste and a significant tonnage of commercial and industrial food waste from landfill.

It will also produce renewable energy for the national grid and a nutrient-rich organic fertiliser.

The planned facility — due to start treating the council’s waste in 2013 — will be designed, constructed, operated and maintained under a 15-year contract.

It will be the first AD facility in Wales specifically designed to take local-authority source-segregated food waste and is said to have the potential to generate enough electricity annually for around 750 homes, as well as produce a valuable biofertiliser for use on nearby farmland.
