According to the literature, BSG can be used as a replacement of other biomasses such as sawdust or wood particles for already know composite materials. Several studies have been reported with BSG introduced as filler for construction materials, such as bricks (3.5-15 wt% of BSG), or for the production of particle board with unaltered properties if the amount of BSG is kept below 10 wt%. It was also used as a sawdust replacement for isocyanate composite materials but resulted in a performance decline with properties being halved due to BSG's presence. Polyurethane and polyisocyanate foams have also been mixed with 16.7 wt% BSG for applications in thermal insulation but the authors focused more on the polymer matrix properties rather than the impact of the filler. Ferreira et al. designed composite materials from BSG and potato starch by hot pressing to produce inexpensive natural composite materials, to be compared with EPS (extended polystyrene). Several BSG percentage were investigated yielding materials with higher flexural strength and rigidity than the standard EPS. However, it was shown that these materials were prone to water uptake, drastically reducing their performances. The addition of a crosslinker, chitosan or glyoxal, or the coating of the produced trays with beeswax were proposed as innovative strategies and successfully reduced water absorption and avoided the drop in performances previously observed. BSG can also be used as filler for composite materials using more traditional plastics.
