Abstract
Herein we describe shotgun shells each having a degradable wad comprising a polyhydroxyalkanoate polymer, as well as methods for ensuring that such wad degrades quickly after landing in an aquatic environment. Plastic, aquatic debris has a negative economic and ecological impact, and thus it is advantageous to use implements that will degrade into environmentally benign compounds. Incorporating a degradable wad into shotgun shells provides an effective, economical solution. Suitable degradable shotgun wads and methods are described herein.
