Life Cycle Assessment as a tool for resource optimisation of continuous basalt fibre production in Iceland - (PPT)

摘要

An electric Icelandic production may result in lower emissions than the Russian production. In both cases furnace energy consumption is identified as the largest contributor. The reduction of furnace energy consumption is dependent on numerous parameters, such as type of furnace, furnace size and CBF production rate. Energy input decreases with increased production capacity (kWh per kg of continuous basalt fibre produced) due to the increased size of furnace, however a larger furnace requires continuous operation and takes longer to heat up. For most environmental indicators, carbon fibre followed by glass fibre are much less environmental friendly than CBF, including those produced in Russia. Future work will include: 1. a sensitivity analysis to evaluate the effect of the size of the plant; 2. an economic evaluation using LCC; 3. a comparison of the different fibers based on an application (e.g. building element).
