The US Army seeks proposals for biodegradable ammunition to replace the existing rounds used in training — including grenade and tank rounds – citing environmental concerns. The DoD stipulates that the new ammunition should contain seeds that produce food for animals. Brief:
Components of current training rounds require hundreds of years or more to biodegrade. Some of these rounds might have the potential to corrode and pollute the soil and nearby water. Some of these rounds might have the potential to corrode and pollute the soil and nearby water….This effort will make use of seeds to grow environmentally friendly plants that remove soil contaminants and consume the biodegradable components developed under this project. Animals should be able to consume the plants without any ill effects.
