After the complete design of the prototype, MFC4Sludge partners have joined efforts in order to build the 10L pre-commercial protoype. Such prototype has been installed at GURAK facilities, more specifically, at Alduna in San Sebastian (Spain). There, at the wastewater treatment plant operated by GURAK, the prototype will be tested under real operational conditions. This will contribute to the technology upgrading, paving the way for market penetration.

A start-up phase follows the construction of the prototype and it is expected that both systems, the partial anaerobic digestion and the microbial fuel cell can provide as good results as have been shown at lab-scale during the first part of the project.

Some pictures of the building process are provided next.
