**Abstract**
 High density polyethylene (HDPE) - coffee dregs (COFD) composites were studied over a range of seven different temperatures, under isothermal crystallisation conditions, using differential scanning calorimetric (DSC) analysis. The aim was to observe the influence of filler content in the crystallisation kinetics of HDPE. Seven blends were prepared, the polymer-filler ratio ranging from 100-0 to 40-60%. The results were evaluated using the Johnson-Mehl-Avrami-Kolmogorov equation. The equilibrium melting temperature was determined by applying the Hoffman-Weeks method. The materials were also evaluated through scanning electron microscopy, differential scanning calorimetry and thermogravimetry/derivative thermogravimetry. 32 Refs.
