The presented paper investigated the influence of brewers’ spent grain (BSG) extrusionparameters on the photo-oxidative resistance of poly(ε-caprolactone)-based wood polymer composites.Filler samples characterized by the higher melanoidin content were more efficient in hindering of polymerdegradation, inhibiting the decomposition of the polymer amorphous phase. As a result, deteriorationof mechanical performance was limited, which was expressed by the higher values of aging factorfor samples containing BSG extruded at higher temperatures.
