Paper: -Hemp paper can be made from both the outer fibres of the hemp stalk (bast fibres) as well as the inner core (or âhurdâ fibres) of the stalk. [li]. -One acre of hemp (grown in a single season) yields as much paper as up to 4 acres of trees (which take many more years to grow). [lii]. -Hemp paper is stronger, acid free, has a longer shelf life and costs less than half as much to process as tree paper.
