the following link, it is possible to appreciate the final
explanatory video of the LEGUVAL project.
the last three years, RTD performers from Europe (CNR-IPCF of Pisa, SSICA,
Tecnalia, and Polieko) have been working together with three industry
associations (Consebro, PCS, ASSOCOMAPLAST) and five companies (Iris, Tehnos,
RDX, Tuba, Lagrana) to find more sustainable, and renewable, sources for the
particular, the main achieved goal of the LEGUVAL project has been the
valorisation of by-products that are currently discarded by the legume
processing industry, in order to use them in the preparation of materials for
agriculture, packaging and automotive applications for the plastics industry.
researchers involved in the project have adjusted the formulation so as to
produce plastic materials easy to be processed at pilot scale, with the aim of
integrating such materials into current industrial facilities. Moreover, the
leftover biomass is being employed as additive for the preparation of
composites and evaluated as a source of energy by anaerobic digestion, which
will add new value to legume by-products .
studies have been finalised and developed during the second half of the project
to validate the results at industrial scale.
most relevant achievements of the LEGUVAL research were the following:
simple and sustainable method for extracting proteins and fibers from legume
by-products, achieving high percentages in the final extracts.
recyclable, non toxic and environmentally friendly multilayer system based on
PLA and LEGUVAL coating with improved barrier properties.
biodegradable formulation to convert legume protein powder into thermoplastic
material, and suitable processing conditions for its plasticization and
formulation to prepare bio-based and biodegradable composites based on a
plasticised bio-based polymer matrix added with legume fibers, and suitable
processing condition for the transformation of the developed biodegradable
fractions isolated during the treatments
of legumes by-product were used as source of biogas in continuous mode
research leading to these results has received funding from the European Union’s
Seventh Framework Programme for research, technological development and
demonstration under grant agreement no. 315241 (www.leguval.eu).
