A method of manufacturing a pallet made of a composite cellulose fiber reinforced polyethylene is disclosed. The composite polyethylene is produced through a process which blends preheated cellulose fibers with molten polyethylene. The blend of polyethylene and fibers is combined with ozone gas to form a polyethylene and fiber matrix. The polyethylene and fiber matrix is then fed to an extruder where it is further mixed, heated and then extruded through one of a series of dies to create the components of the pallet. The pallet has excellent rigidity and is welded together by coating meeting surfaces with a bonding material of blended high density polyethylene and iron oxide, placing the pallet into an electromagnetic field, and energizing the pallet with electromagnetic field having a frequency between 1 megahertz and 100 megahertz, causing the bonding material to melt and fuse the meeting surfaces.
