A New, 100% Biodegradable Anchoring Staple

Green_e-staple_photo_mediumAmerican Excelsior Company offers E-Staple®, a 100% biodegradable turf staple, which is not just another turf staple.  E-Staple is the result of years of research and development that has produced the most unique turf staples available today.        

Material Characteristics

E-Staple’s unique composition sets it apart from other 100% biodegradable staples.  E-Staples are comprised of a natural plastic that originates from materials that are abundantly grown in the United States.  E-Staple composition is Polyhydroxyalkanoate (PHA) plastic that is made from plant sugars and oils.  ”Natural plastics” eliminate the use of petroleum-based materials, which ultimately helps reduce our dependency on oil.  This innovative composition produces unique and unmatched physical and chemical features and benefits.  All of these features and benefits, along with the independent pull out testing results vs. other turf staples, are detailed in the E-Staple TechNote.

E-Staples biodegrade by a surface attack mechanism triggered by soil microbes naturally present in the soil.  With this in mind, E-Staples will biodegrade fasteCircled_E-Staple_in_Side_View_mediumr in more fertile soil because that means there are more microbes breaking down the material.  E-Staples biodegrade in cold (43 °F) to hot (180 °F) conditions and do not require a pre-hydrolytic reduction in molecular weight for degradation to begin.  Pre-hydrolytic reduction generally requires a hot (140 °F – 149 °F) and moist composting step, which is not a common condition for soils where turf staples are used.  E-Staples will biodegrade completely from the soil in 8-24 months depending on site conditions.
