Maple Sap Tapped as Potential Green Products Source

The maple tree already provides Canadians with a beautiful part of the landscape, a national emblem and the sticky sweet syrup created from its sap. Now researchers have tapped into a new use for the sap: a base for a natural, biodegradable polymer, one they say may reduce our dependence on fossil fuel-based plastics. The discovery could potentially provide a new range of biodegradable products such as more environmentally friendly packaging material, and could be used for medical applications like drug delivery systems and surgical sutures
