The BIO+ Project involves valorising waste for energy through anaerobic digestion. The technological improvements developed by this project have led to greater efficiency and environmental protection.

The aim of this project is to valorise the non-hazardous waste managed by FCC as well as the sewage sludge generated at facilities as part of its integrated water management activities, using anaerobic process technology to increase biogas production. It also minimises environmental impacts and reduces costs.

Proven useful benefits

Using the BIO+ project technology for waste valorisation meets two key objectives. The first of these is increased production of biogas as a source of renewable energy. The second is the reduction in the amount of biodegradable waste sent to landfill.

Other benefits include the improved quality of biosolids as a result of anaerobic waste digestion, and increased destruction of the volatile solids during the process.

In order to achieve these objectives, certain operating conditions are fundamentally important, such as thermal hydrolysis using Cambi technology, and the ability to harness the complementary composition of urban waste and sewage sludge, among others.

Allows knowledge to be exchanged

The Bio+ Project is part of a research line that was launched in 2002 in partnership with private and public institutions in Spain and France.

Particularly noteworthy has been its collaboration with the University of Salamanca through the Centre for Water Research and Technological Development (CIDTA), as well as the University of Huelva and the Biotecnologie de l’Environnement laboratory at the Institut National de la Recherche Agronomique INRA (Montpellier Centre).
