AB  - The current work discusses ground coffee waste (GCW) reinforced high-density 
      polyethylene (HDPE) composite. GCW underwent two types of treatment (oil 
      extraction, and oil extraction followed by mercerization). The composites were 
      prepared using stacking HDPE film and GCW, followed by hot compression molding 
      with different GCW particle loadings (5%, 10%, 15% and 20%). Particle loadings of 
      5% and 10% of the treated GCW composites exhibited the optimum level for this 
      particular type of composite, whereby their mechanical and thermal properties 
      were improved compared to untreated GCW composite (UGC). SEM fracture analysis 
      showed better adhesion between HDPE and treated GCW. The FTIR conducted proved 
      the removal of unwanted impurities and reduction in water absorption after the 
      treatment. Specific tensile modulus improved for OGC at 5 vol% particle loading. 
      The highest impact energy absorbed was obtained by OGC with a 16% increment. This 
      lightweight and environmentally friendly composite has potential in high-end 
      packaging, internal automotive parts, lightweight furniture, and other composite 
      engineering applications.
