Reclamation and Recycling of L8A1 Red Phosphorus Grenade Mix

Abstract

Mix from unserviceable L8A1 red phosphorus grenades was recovered and recycled as feedstock for L8A3 red phosphorus grenades. Reuse of the mix avoided destruction of the L8A1 mix as a waste and reduced the amount of new raw materials needed for the manufacture of L8A3 rounds. Both control L8A3 grenades (made from all new raw materials) and experimental L8A3 grenades (made from recovered L8A1 mix) were placed in storage at cold conditions (-51 deg C, -60 deg F), ambient conditions (21 deg C, 70 deg F), and hot conditions (65 deg C, 150 deg F). Control and experimental rounds were fired after approximately one week of storage and approximately ten weeks of storage. The experimental L8A3 grenades generated smoke equivalent in quantity and quality to the control L8A3 grenades. Significant cost avoidance was realized through successful reclamation and reuse of the L8A1 mix in the L8A3 grenade manufacturing program.
