Publication number: 20170160062Abstract: 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.Type: ApplicationFiled: December 15, 2016Publication date: June 8, 2017Inventors: Kirk J. Havens, Donna Marie Bilkovic, David M. Stanhope, Kory T. Angstadt, Wade K. Blackwood

Publication number: 20150135580Abstract: Herein we describe fishing gear having a degradable component comprising a polyhydroxyalkanoate polymer, as well as methods for ensuring that such gear has reduced functionality after becoming derelict. Derelict fishing gear has a negative economic and ecological impact, and thus it is advantageous to use gear that will lose the ability to catch and retain fish over time. Incorporating a degradable apparatus into such gear provides an effective, economical solution. Suitable degradable components are described herein.Type: ApplicationFiled: January 23, 2015Publication date: May 21, 2015Inventors: Kirk J. Havens, Donna Marie Bilkovic, David M. Stanhope, Kory T.
