• Maintain EU companies and Institutes at forefront of CF processing technologies.
Potential impacts of LIBRE
LIBRE utilised lignin rich side streams from European biorefineries as carbon source materials. This new fully bio-based feed stock will allow European producers to rely less on imported precursors and imported CF, thereby securing a sustainable, indigenous, European CF manufacturing base not reliant on petrochemical based precursor materials.Between 40 and 50 million tons of lignin are produced worldwide per year; while some is being used for low- and medium-value applications (e.g. binding and dispersing agents in materials such as cement and bio-based leather substitutes most is currently treated as a non-commercialized waste product or a low value fuel to produce energy - representing a market value of roughly $730 million).
LIBRE went beyond the state of the art by producing CF from cheaper bio based precursor materials utilising newly developed energy efficient microwave processing techniques.
The LIBRE consortium has validated 3 new bio based products in WP7: Components for the automotive industry, aircraft secondary structures and wind turbine blades
LIBRE established a new value chain for lignin by utilizing low commercial value waste material (WP1) to produce CF which will inturn be processed into CFRP for high value added applications in the automotive, energy and construction sectors (WP7)
LIBRE has increased competiveness through 1) the liberation from petroleum based products such as PAN precursor, 2) novel routes for the reuse of waste lignocellulose streams and a more cost effective production base allowing new materials and materials processing techniques to be developed cheaply and efficiently. LIBRE will enable EU industries to lead the way by directly targeting end users in the transportation, energy and construction industries. LIBRE will aid in the transition towards a competitive European bio economy with all the associated societal implications in terms of jobs creation in rural areas, and sustainable development.
