Wood mulch - shredded paper and styrofoam. 32 hours to make one of these domes by Aircrete Harry. You make the air form out of Tyvek. Lay out a patterm of masonite. Lay tyvek on top. 12 pieces stacked. Then you use angle iron, slit part way, as arches. Use a leaf blower. Plus flap on top, that controls the amount of air pressure. Grout - cement + sand stiffens it up. Use 8" styrofoam. Leave blower running until insulation layer is done.
