Method & Evidence

AimTo investigate the potential of activated sapropel as an ecological binder for wood processing waste to develop a thermal insulation biocomposite, and to analyze the influence of binder activation, particle size, and compaction on its thermal conductivity and compressive strength.
MethodExperimental research and materials testing.
ProcedureSapropel was mechanically activated to improve its consistency and tensile strength. Wood processing waste was used as filler, with particle size controlled. Biocomposites were fabricated using varying amounts of sapropel, different levels of mixture compaction, and controlled wood particle sizes. Thermal conductivity and compressive stress were then measured.
