  • Patent number: 10480914
    Abstract: Herein we describe embodiments of shotgun shells, methods for loading such shotgun shells, and methods for using them. In some embodiments, the shotgun shells utilize a multi-component wad system with a biodegradable powder wad that stays intact through the firing process, and a separate and chemically distinct biodegradable shot wad that breaks apart within one meter after being shot out of the barrel of a shotgun. A clean release of the shot can be obtained, providing both high performance and biodegradability. The biodegradable shot wad can be a biodegradable polyester.

  • Patent number: 10393486
    Abstract: Herein we describe embodiments of a biodegradable wad having a gas sealing function, as well as methods for their use. In some embodiments, the biodegradable wad comprises at least 50% by weight of a poly(butylene succinate co-adipate) polymer. In some embodiments, the biodegradable wad comprises at least two biodegradable polymers, wherein a first biodegradable polymer comprises a polybutylene succinate adipate polymer and a second biodegradable polymer comprises a polyhydroxyalkanoate polymer. Plastic 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 biodegradable wad into shotgun shells provides an effective, economical solution, provided cost is acceptable and performance is not compromised. Suitable shotgun shells utilizing biodegradable shotgun wads and methods are described herein.
