A machine for compacting agricultural fibrous matter into a board, said machine comprising:
- a hopper for receiving the agricultural fibrous matter;
- and
- an extruder, the extruder comprising:
- an extrusion passage downstream of the hopper;
- and
- a ram configured for moving in a reciprocal manner along the extrusion passage, wherein
