Streszczenie
Plastics and cellulose are widely used in various branches of industry and in households, which affects the state of
the natural environment in terms of waste generation. Currently, the methods of disposal of plastics and cardboard produced
from cellulose include recycling, landfilling, and energy recovery. Therefore, rational waste management – including recy
cling, proper disposal and use, as well as continuous improvement of existing technologies and the implementation of inno
vative solutions – is extremely important for environmental protection.
This study undertook exploratory research on the possibility of utilizing HDPE polyethylene waste and cardboard. For this
purpose, thermal analysis techniques (DSC), FTIR spectroscopy, microscopy, and measurements of functional properties
were employed. The research was carried out for polyethylene recyclate and polyethylene composites with cardboard fibre,
with the maximum mass content determined by the applied processing method. Polyethylene composites containing 3% and
7% fibre were examined. The influence of the filler on changes in thermal parameters and the effect of structure on function
al properties were observed.
