Abstract
This study focuses on the effect of environmental factors on composites of polylactide and lowdensity polyethylene with oxidized polyethylene added as an analogue of recyclable materials. Moisture and ultraviolet light were found to significantly affect the polylactide–polyethylene composites at the first stage. The presence of oxidized polyethylene in the composite containing 30 wt % polylactide has a minor effect on water uptake by the composites. The average weight loss in the samples incubated in soil for 360 days is 5–10%.
