Comment gérer la biomasse végétale issue des phytotechnologies ? Perceptions des opérateurs de filières de valorisation

Abstract : A survey was carried out in 4 European countries to gather end-user’s perceptions of using plants from phytotechnologies in combustion and anaerobic digestion (AD). 9 actors of the wood energy sector and 11 AD platform operators from France, Germany, Austria and Sweden were interviewed. Questions related to installation, input materials, performed analyses, phytostabilization and phytoextraction. Although the majority of respondents did not know phytotechnologies, results suggested that plant biomass from phytomanaged areas could be used in AD and combustion, under certain conditions. As a potential advantage, these plants would not compete with plants grown on agricultural lands, contaminated lands being not suitable for food/feed production. Main limitations would be related to additional controls in inputs, end-products and installations that might generate additional costs. In most cases, the price of biomass from phytotechnologies was mentioned as a driver to potentially use it. Plants used in phytostabilisation were thought to be less risky and benefited from a better theoretical acceptance than those issued from phytoextraction.
