This paper discusses activities and results of the REBAF project: a two-year Italian regional research project focused on the energy conversion of biomass residues from river, canals and basins maintenance activities. Innovative pathways for the exploitation of grass and woodsy biomasses were investigated. Gasification and pyrolysis are the key technologies for biomass conversion into energy. Woodsy biomass was tested as fuel in a small scale commercial gasification power plants that produce heat and power using a IC engine. A valuable by-product of the process was biochar. This was tested as soil improver in giant reed crop parcels and a sensible increase of dry biomass production was achieved in comparison with control parcels. The grass residues obtained from canals maintenance were carbonized in lab-scale pyrolyzer at a temperature of about 450 °C through the hot exhaust of the engine fueled by the gasifier. The pyrolysis gases were used directly in the gasifier in substitution of the gasifying agent. The residual carbon afterward the pyrolysis process was used as filler in cements, plasters and polyurethane panels increasing performance of these building materials.

Abstract

This paper discusses activities and results of the REBAF project: a two-year Italian regional research project focused on the energy conversion of biomass residues from river, canals and basins maintenance activities. Innovative pathways for the exploitation of grass and woodsy biomasses were investigated. Gasification and pyrolysis are the key technologies for biomass conversion into energy. Woodsy biomass was tested as fuel in a small scale commercial gasification power plants that produce heat and power using a IC engine. A valuable by-product of the process was biochar. This was tested as soil improver in giant reed crop parcels and a sensible increase of dry biomass production was achieved in comparison with control parcels. The grass residues obtained from canals maintenance were carbonized in lab-scale pyrolyzer at a temperature of about 450 °C through the hot exhaust of the engine fueled by the gasifier. The pyrolysis gases were used directly in the gasifier in substitution of the gasifying agent. The residual carbon afterward the pyrolysis process was used as filler in cements, plasters and polyurethane panels increasing performance of these building materials.
