The technology, developed by CNR-ICB, is based on an innovative bioprocess called "Caphnophilic (CO2-requiring) Lactic Fermentation (CLF)”, developed in the hyperthermophilic bacterium Thermotoga neapolitana (EP patent: EP2948556B1), which allows the production of "green" hydrogen and capture and valorization of CO2 in L -lactic acid (98% e.e.).

The invention is about the development of a device and its methodology for measuring the active and reactive sound intensity from the impedance computation. The active intensity is calculated directly in the frequency domain multiplying the complex impedance and power spectrum of the air particle velocity. A second line of post-processing is applied to obtain the overall complex sound intensity.

Geopolymers belong to the class of chemically bonded ceramics: they are synthesized at low temperatures and are eco-friendly, as besides the low consolidation temperature required by the process they can be produced from secondary raw materials and industrial waste of various kinds, thus reducing the energy demand and the environmental impact of the entire production cycle. Materials such as fly ash, steel mill slag, biomass ash, sludge and silt, extractive residues, mineral and ceramic powders, organic or inorganic waste fibers, plastics, etc.
