Plant fibres for insulation or reinforcement


A number of regional projects have been carried out in this field during the past 10 years. Plant fibres, primarily hemp, but also flax, sisal, coir and ordinary wood pulp, have been subject to studies as to their properties and potential as reinforcement in concrete. In one particular case, elemental sulphur was used to replace cement and water in a hemp fibre reinforced concrete intended for use in severe chemical environments. Materials Technology has also carried out projects emphasizing cultivation, harvesting and renewable energy aspects of hemp. The most recent project has involved processing of hemp using tornado technology. This implies that the hemp is dried and decorticated in one single step. In this way fibres suitable for insulation purposes can be produced in a cost effective way.
