Basalt fibers are increasingly being used for various structural engineering applications. Production capacity is being ramped up globally. There was a lot of experience with this material in the Soviet Union, where basalt was used mostly for military applications. Ex-Soviet countries is still where most of the experience is (Ukraine in particular). Given that the Soviet Union disintegrated almost 20 years ago, much of this information should be in the public domain now, but may not be easily accessible.

Will it scale down ?
Let's not kid ourselves, this is a high-tech, difficult process. Not all basalts work, and the material has to be heated up to 1,400°C (2,550°F). This all sounds very capital intensive. Still, this can potentially be made to work on the small scale, and the fibers could displace some steel and even carbon fibers.
Product Ecology
Biogas -- methane from biogas can be used to heat the basalt.
Gasifier -- alternatively, syngas can be used for melting.
Induction_Furnace -- can melt glass, so it should also be able to melt basalt.
Waste heat -- In cold climates, any kind of waste heat can be used for heating winter greenhouses and for other space heating needs.
