1. A biocomposite material fabrication method, comprising:
compacting along a plane a cultured biomass comprising cultured plant and/or algae cells from a suspension culture, the cultured plant and/or algae cells having a water content of at least 10 wt %, and a turgor pressure,
the compacting performed by continuously applying to the cultured biomass an increasing pressure perpendicular to the plane until reaching an applied pressure corresponding to the turgor pressure of the cultured plant and/or algae cells to provide a compacted biomass;
the method further comprising
drying the compacted biomass by
a) applying a drying pressure to the compacted biomass, and/or
b) applying a drying temperature to the compacted biomass,
to obtain a biocomposite material having a water content from 0.1 to less than 15 wt %, a mass loss from the cultured biomass of 80-99 wt %, and/or a dry density of 500-1500 kg/m3.
