Ringtest

Grow2Build has carried out a so called "ringtest". What is a ringtest?

The idea of a 'ringtest' is to compare the performance of decortication lines. A number of flax and hemp decorticators from different countries have been selected to participate to this ringtest. Those companies will all receive a certain quantity of the same flax and/or hemp straw, and will process it on their respective decortication line. The final products from these production lines will be analysed in the laboratory of one of the Grow2Build partners.
With the technical results obtained from the analyses, the best possible applications for the different products will be determined and some recommendations will be made by the project partners in order to improve the performances of those products and/or decortication lines.

With the 'ringtest' the industrial decorticators and the project partners have worked together towards a larger and better use of flax and hemp fibres in the building sector.
Results ring test on flax and hemp products – Celabor
In order to support the utilisation of flax and hemp building materials from production of raw material to the realisation of end products at a consumer level, a ringtest has been carried out with hemp and flax. By the ring test, processors got the opportunity to obtain an objective evaluation of the fiber quality they produce in comparison with average quality profiles.

Technical results

Pilot with Chanvribloc - Crepim
The goal of this pilot test is to improve the fire reaction of hempcrete manufactured by CHANVRIBLOC. As hempcrete is a construction element, it is subjected at European fire reaction tests: EUROCLASSES system.

Study on biocomposites - Materia Nova
The study consists in the preparation and characterization of composites with thermosetting matrices (for the moment) totally or partially bio-sourced reinforced by unidirectional long fibers of flax.

Report on enzymatic Flax Retting for Potential Bio-composite Applications - Saxion
This report is benchmarking study in the area of enzymatic flax retting process for potential biocomposite application. A state of art of conventiaonl flax retting process have been presented with all the associated advantages and disadvantages. A systematic approach has been adopted to design and partially scale up enzymatic flax retting process.

Report on Ten Cate: Development Midstream processing of Flax-fiber - Saxion
Overall, the reported implicates that quality fiber production from flax plant can be a feasible, sustainable and a renewable production process. Feasibility of the process can be obtained by, (1) retting at low-cost process conditions of 20°C and using water without any addition of chemicals, (2) with increased flax retting rate by recycling water, (3) with increased flax retting rate by introducing mixing forces, and the ability to lower the energy consumption of the overall process, (4) producing biogas from the COD with anaerobic digestion and (5) producing pyrolysis oil and pyrolysis charcoal.

Report on protection of wood with a biofilm
The results achieved up until now show the feasibility to protect wood with a biofilm. All-important process steps required are at least at the stage of pilot or demonstration. Although some steps still have to be taken in order to be able to upscale the different production facilities, the overall project is on track to have the first pilot products on the market end of this year (2015). Furthermore additional projects are initiated to create the resources required to pursue progress in the development of this wood protecting technology in future.
