| Technology description including background system | The LCA of 1 kg of flax fleece covers the cradle-to-gate phase, that is, the production of raw materials, the agricultural flax production and the fleece production including packaging. The insulation fleece consists of 85% flax fibres and 15% polyester fibres as support fibre. At the end, the raw fleece is impregnated with 4% soda, referring to the weight of the raw fleece. The system boundaries are represented by the ready-for-shipment product at the factory gate. Transports from the factory to the building site are not considered and must be included according to the system boundaries. In module C1, a manual dismantling (no loads) is assumed, collecting losses are neglected. The transport in module C2 to the recycling plant takes place with a truck (50km). Module C3 takes into account the grinding and thermal treatment (combustion) of the material. It is assumed that the material reaches the end of the waste status immediately after dismantling. The CO2 absorbed and stored in the material by photosynthesis (from module A1) is written off in C3 (CO2 neutrality within the product system according to EN 16485: Round and sawn timber - Environmental Product Declarations - Product category rules for wood and wood-based products for use in construction, 2014). Module D contains the loads through the operation of the recovery facility (excluding biogenic CO2, see above) and credits for the substitution of electricity (German electricity mix) and thermal energy (from natural gas). The calculation of combustion emissions and credits takes into account the specific calorific value of the material and the material composition. |
