How To Make Wpc

Wood (or a cellulose equivalent, such as rice hulls or wheat straw) provides the other major component of WPCs. It's ground into what's known as flour–particles so small that you can put 100 in a line and not cover an inch.

Whey protein isolate (WPI) contains the highest amounts of protein, which explains why it is often used in sports nutrition in the form of whey protein supplements, protein shakes and beverages and protein bars . Whey protein concentrate (WPC) also contains protein, but not at the high levels found in WPI.

Companies also use plastic from factory rejects that were reground. Wood (or a cellulose equivalent, such as rice hulls or wheat straw) provides the other major component of WPCs. It's ground into what's known as flour–particles so small that you can put 100 in a line and not cover an inch.

The wood flour used in WPCs has to contain far less moisture than one would find in nature, so before going into the hopper, it gets heated and dried until it's almost free of water. At the same time, the plastic–which looks like soap flakes–is heated to a liquid state.
