This project seeks to improve energy efficiency by promoting cogeneration from biomass or biofuel. This highly energy-efficient technology also produces electricity and exploitable heat simultaneously. Cogeneration engines may be powered by several types of combustible matter. Ecotec 21 intends to test these – particularly glycerol as well as waste from the agricultural and wood industries – by installing engines in various existing infrastructures to study the resulting energy benefit. It is also planning on facilitating these installations by listing the related procedures and establishing models (installation authorisation, supply contract, energy management, etc.). Lastly, it is going to raise users', inhabitants' and decision-makers' awareness.
