Abstract: The ISOBIO project proposes an innovative strategy to bring bio-based construction materials
into the mainstream. A key innovation consists of the use of bio-based aggregates from a local
culture, with green binders for the production of ecofriendly composites. This work aims to
combine existing technologies in order to develop bio-based panels with high insulating
properties, low embodied energy, low embodied carbon and hydrothermally efficient. This study
aims to value the agro-resources by-products from flax, hemp, corn, rape and wheat, provided
by one of the project partner, for find out new alternative materials that respond to sustainable

development criteria. In the present work, the chemical characterization of agro-resources’s by-
product are studied by Van soest method and Phenol sulfuric method to determine the content of

cellulose, hemicellulose, lignin and polysaccharides. Measurement of thermal conductivity and
Moisture Buffer Value are also achieved in these raw materials to determine their hygrothermal
properties at bulk density. Thermal Conductivity and MBV evolve according to the density
whatever the agro- resources type. All these materials have different properties but they are all
excellent hygric regulators. These results suggest that agro-resources’s by-product may be used
as a raw building material but not for the same types of use. In fact, some raw materials would
be more suitable for thermal insulating products and others would be better suited to indoor
facing panels.
