The biodegradable badge has a paper name tag placed within a translucent envelope carried by a lanyard secured to the envelope by at least one clamp. The paper name tag degrades readily. The translucent envelope shows the name tag but upon disposing of the envelope, it degrades in the waste stream and at a landfill. The envelope has a material that degrades rapidly by solar, thermal, and chemical action with minimal release of toxic and volatile organic compounds. The lanyard also degrades readily in the waste stream with material such as textile blends or that of the envelope. The clamp joins the lanyard to the envelope. Designed for single use, the clamp strongly grips the lanyard and then the envelope, and then the clamp degrades when placed in the waste stream. The entire biodegradable badge poses no long-term pollution of the environment as it uses formulations, such as polyethylene terephthalate (g) and poly lactic acid, along with natural fibers such as cotton and wool.
