| abstract |
The present invention provides an explosive charge that includes a casing containing explosive material, a cap coupled to the casing, and fungal spores that, when activated, metabolize and degrade the explosive material. The fungal spores may be located in the ullage of the casing, contained in a biodegradable cap, or encapsulated in biodegradable pellets that are mixed into the explosive material. A wicking strip and/or deliquescent salts may be used to draw moisture into the charge in order to activate the fungal spores, and supporting nutrients may be added to help support fungal metabolism. In one embodiment, the casing also has a biodegradable plug that allows moisture into the casing to support fungal growth. The casing itself may also be biodegradable. |
