Combined with the Road article that indicates 13M acres of available roadsides - and bale density of 110 kg/m3, [1] - and a bale yield of approximately 2 dry tons per acre [2] - we have:
- 26 million tons of bales
- 236 million cubic meters of bales
- 19" straw bales (~50 cm) - R27 [3]
- One cubic meter of bale gives about 2 square meters of wall insulation.
