ABSTRACT = {Novel mycelium-based biocomposites (MBB) were obtained from local
agricultural (hemp shives) and forestry (wood chips) by-products which were
bounded together with natural growth of fungal mycelium. As a result, hemp
mycocomposites (HMC) and wood mycocomposites (WMC) were manufactured.
Mechanical, water absorption and biodegradation properties of MBB were investigated. MBB were characterized also by ash content and elemental composition.
The results of MBB were compared with the reference materials such as the commercial MBB material manufactured by Ecovative<sup>®</sup> Design (EV), hemp magnesium oxychloride concrete (HC) and cemented wood wool panel (CW),
manufactured by CEWOOD<sup>®</sup>. The mechanical properties of HMC and WMC
showed that the bending strength difference was about 30%, with a better result
for HMC. Compression strength was better for WMC by about 60% compared to
that of HMC. The mechanical strength of HMC and HC materials was equal; both
materials contained hemp shives but differed by the binding material. Water
absorption and volumetric swelling tests showed that HMC and WMC could
be considered as potential biosorbents. Ash content and elemental analysis
showed that reference materials (CW, HC) contained significant amounts of inorganic compounds that decreased the biodegradation rate, compared to the case of
HMC and WMC materials. The biodegradation results of HMC and WMC, after
12 weeks, revealed a mass loss (ML) above 70%, while in the case of EV, HC and
CW, it was about 60%, 17% and only 6%, respectively. MBB were completely
biodegradable.},
